1.2 Rotary switches and keys (buttons)
The following controls are mounted on the front face of the LX7007 DU
•
•
Four rotary selector switches
Six push buttons
The LX7007AU is an indicator only and has no controls; the displayed information being controlled from the
LX7000DU
ENTER button
START/ON button
VOLUME selector
ESC/OFF button
MODE selector
UP/DOWN selector
ZOOM selector
MC button
BALLAST button
EVENT button
1.2.1 ON/START button - Switching the Instrument ON and OFF
The ON/START button is multifunctional. If the instrument is not already powered up, a short press on the
ON/START button will switch the instrument ON. To switch the instrument OFF, press the ESC/OFF button for a
few seconds and the instrument will switch off. If an attempt is made to switch the instrument off during flight, the
instrument requires confirmation from the pilot, so the LX 7007 PRO IGC cannot be switched off by mistake. On
powering the unit, the first screen shows the firmware version, database version, serial number of the unit, and total
memory in hours available for IGC flight records. After a few seconds, a second screen shows details of the glider and
pilot. The unit is equipped with a facility of storing up to 30 pilot names. If no names are stored, the unit shows the
pilot name as UNKNOWN. By rotating the UP/DOWN selector, the display scrolls through the programmed pilots.
Once the correct pilot is selected, pressing the ENTER button selects the airfield elevation screen and the current
elevation should be entered, again using the UP/DOWN selector and the ENTER button. Similarly, the current QNH
should also be entered. The airfield elevation input is mandatory while the QNH input optional (See Para 3.1.1.1)
During flight the same button is used to start the task, to see more characters of airport names and, in the edit
menu, to go back one step if an error has been made (see paragraph APT).
Note!:
During flight, if main power is lost for a few seconds, the flight recorder will not produce two flights. The most
important flight parameter, altitude will remain, which means that the final glide is not interupted.

1.2.2 MODE selector (rotary switch)
The mode selector is used to change modes of operation. This switch has the highest priority in the system. Whenever
it is operated, a mode change will occur.
1.2.3 UP/DOWN selector (rotary switch)
This rotary switch has a lower priority than the mode selector switch and is active all the time in the selected mode. It is
mainly used for selecting sub menus during navigation and to scroll in the edit menu.
1.2.4 ENTER button
The main function of this key is confirmation, and to start edit procedures.
1.2.5 ESC/OFF button
This is a multifunctional key, which has two main functions. If it is pressed and held for a few seconds, then the
instrument will turn OFF as outlined in para 2.2.1 above.
If a short press is made, then the button has the following functions:
•
•
The display will jump to the menu of the next higher level (in edit only)
During alpha-numeric input with the cursor active (blinking), ESC confirms the whole line (It is not necessary to
press ENTER few times)
•
Some special functions can be activated using ESC as described in subsequent paragraphs
1.2.6 EVENT button
Activates the Event function (see Chapter 3.1.1.2, Flight Recorder)
1.2.7 MC and BAL buttons
Pressing these buttons activates the Mc Cready (MC) and ballast setting as shown below. The value is then changed with
the UP/DOWN-selector. There is no secondary function of these buttons.
1.2.8 ZOOM (rotary switch)
This is a multifunctional rotary switch. While its main function is to change the zoom level in the graphic mode, it can
also be used as follows:
•
•
•
To select turn points when in the main TP page
To select task when in the main TSK page
If an error is made during editing, it is possible to move the cursor back by rotating this knob. This can only be
done if 'editing' is active which is shown by the cursor blinking

available.
96990
The selection of the system parameters that are fixed, such as glider type, units, polar etc, are only access able by
entering the password. This facility prevents that well known gliding club pest, "the random knob twiddler" from
changing the important fixed parameters just before you launch on the flight of the year! Once you are airborne, then
the password is not necessary - the second level can be entered simply by selecting PASSWORD and pressing
ENTER.

2.1.1.1 QNH RES (QNH and Safety Altitude)
Input Procedure:
•
•
•
•
Use the UP/DOWN selector to choose the item it is required to change (QNH, MG.VAR, ALT.R. or BUGS)
Press ENTER
Use UP/DOWN to select the value required and press ENTER to input it
Once all changes are complete, press ESC top return to SETUP menu
QNH: Using this feature it is possible to offset the altitude datum, which could have changed due to pressure changes
during the flight. During the initial power up sequence, an option to enter the QNH was presented. If the actual QNH
was entered at that stage, then this feature is active. If the QNH feature was 'stepped over' during power up, then this
function is not active. As changing the QNH influences the indicated altitude, care should be taken when changing the
value as an incorrect setting can upset the final glide calculation.
MG. V. If the GPS receiver calculates magnetic variation then AUTO will be displayed here and no input is possible.
If AUTO is not displayed, then the GPS receiver is not calculating magnetic variation and it is obligatory to input the
magnetic variation for the area being flown over. If this is not done, then all calculated winds and tracks flown will be
true and not magnetic.
ALT.R. This setting is the altitude reserve or safety altitude, and is the height that the instrument adds to the final glide
altitude required so that the glider arrives over the final glide destination at the selected safety altitude. After safety
altitude input, the pilot has has to keep final glide indicator on 0 to arrive on safety altitude.
BUGS: This sets the polar degradation because of “buggy” wings. The input is in percentage degradation of glide
ratio. (5%, means glide ratio degradation is 5%)
2.1.1.2 LOGGER (FLIGHT RECORDER)
The flight recorder is fully approved by the IGC (A sub-committee of the FAI.) and will produce secure flight records
that are acceptable for all FAI requirements including world records.
After selecting LOGGER and pressing ENTER, the following flight recorder settings are accessible.
FLIGHT INFO All important data, such as the pilot's name, glider type, glider registration, competition number and
competition class can be entered. The data is entered with the ENTER, UP/DOWN and ESC routine. This data is
subsequently written into the 'H' record of the IGC flight log. Alternatively, this data can be entered with a PC and the
LXe-program; or via a Colibri or LX20 (see Chapter 4).

Apr.2005
Note!:
The instrument is cabable of storing up to 30 different pilot's names. Each pilot's name, which can be password
protected, can have different flight information programmed into it. This is useful if one likes to fly with a custom
polar, fly the glider in different configurations, or fly in decentralized competitions, Online-Contest, Barron-Hilton-
Cup, etc. For more information on configuring pilot names see 3.4.1, and for for setting custom polars see 3.1.2.10.
Before leaving the FLIGHT INFO menu, the actual name can be saved into pilot list, if not already present.
Note!:
If only one pilot flies the glider, then after entering his name, it is not necessary to enter it into the list. In the
above screen 'N' should be selected to do this. The name will then appear automatically on instrument power up
together with all the parameters that have been set. An exception to this is if he flies the glider in two different
configurations; then he should list his name twice, e.g once with a suffix of 15m and again with a suffix of 18m
with different polars in each name.
LOGTIME is an important parameter as it shows the total memory available for recording the flight.
TOTAL MEMORY is the capacity of memory in hours that can be stored and only depends on the settings. It does
not decrease as flights are stored and will only change after new settings have been made in the setup. If the memory is
full, the oldest flights will be overwritten without warning. The total memory simply indicates how many hours of
flight can be made without loosing any flight data before overwriting occurs.
B-RECORD: This is the main IGC record in which position, GPS altitude, pressure altitude, UTC and GPS status are
stored. The default interval is 12 seconds and it can be changed. As the interval is reduced, the Total Memory will be
seen to decrease.

K-RECORD: This record can be used to store non-essential flight parameters and is not active by default. It should not
be activated unless the IGC record format is fully understood. If required to be activated, the J-Record (see below) will
select the flight parameters that are stored in the K-Record.
NEAR TP INT: This setting enables the fixing rate set by the B-Record to be increased close to a turnpoint to ensure
that a fix is obtained in the observation zone.
NEAR TP RAD: This setting defines the radius from the turnpoint at which increased fixing rate is to start.
(I) RECORD: This record permits additional flight parameters to be added to the B-Record. Except for ENL (Engine
Noise Level), they are all de-activated by default. They can be activated if required by toggling the 'N' to 'Y'.
-FXA: current horizontal accuracy of GPS
-VXA: current vertical accuracy of GPS
-RPM: engine RPM
-GSP: ground speed
-IAS: indicated airspeed
-TAS: TAS
-HDM: mg. heading
-TRM: magnetic track
-TRT: true track
-TEN: total energy
-WDI: wind direction
-WVE. wind
-VAR: vario
-ENL: engine noise level (default Y)
Each setting activated will reduce the total memory capacity.
(J) RECORD: The J-Record defines the flight parameters that are to be stored in the K-Record. These parameters are
the same as those used for the I-Record. Using this record will reduce the total memory by about half.
Note!:
Unless the user has a good understanding of the composition and use of IGC flight records, then it is recommended
that, other than the ENL, no alterations are made to the default selections.
EVENT This option programs what happens on pressing the EVENT button. On pressing the button, the flight
recorder places a special marker, called a PEV (Pilot Event), in the IGC flight record At the same time, it causes the
recorder to run at a different fix interval for a certain time. The interval and time are set up in this option.
Competition rules may require the EVENT to be activated at some stage during the flight.
Example:
The setting above will cause the recorder to log 30 additional fixes at 2-second intervals on pressing the EVENT button.

2.1.1.3 INIT
The following parameters can be set using this option.
•
•
VARIO FIL:
S.V. :
This sets the time constant of the vario from 0.5sec up to 5 secs; the default setting is 2.0 secs
S.V. means Smart Vario, giving four levels of dynamic damping of the vario indication and
off.
•
•
•
•
VARIO INT:
VARIO RNG:
TAB:
This setting defines integration period for the averager in seconds; the default is 20 seconds
This sets the full scale range of the vario
This setting defines the width of the audio dead band in speed to fly mode
This setting selects the parameter, GS, VAR or MC, that is used to calculate the Estimated
Time of Arrival. When flying a programmed task, the calculation takes account of the
unflown portion of the task , around any TPs or APTs not yet reached
ETA:
GS, bases ETA on the achieved groundspeed along track. It takes into account differences
between bearing and track of up to 90°. If the difference is greater than this, --:-- is
displayed.
VAR is based on the achieved average thermal climb rate and assumes that this is going to
continue.
MC is based on the actual Mcready setting.
Note!:
All three methods of calculating ETA and ETE (Estimate Time of Arrival, Estimate Time Elapsed) take into account
glider altitude and safety (arrival) altitude, thus ensuring that the calculation made is the best available
•
AUTO SC:
This option defines the method by which the instrument is switched between vario and speed
command
OFF: Switching is by an external switch
GPS: When the GPS detects that the glider is circling
TAS: When the TAS exceeds a pre-set value. The TAS at which switching occurs can be
selected in 5 km/h steps from 100 up to 160 km/h (or the equivalent in knots or mph)
•
WIND/COMPASS: N.C. means not connected. When the optional compass module is installed, the instrument
uses magnetic track to make an additional wind calculation. The calculation requires the
glider to fly straight a specified period which is set in this option. The default is 15 seconds,
but the longer the period, the more accurate is the calculated wind.
Note!:
The external switch option has absolute priority and will override all other switching methods.

After ENTER on PC the communication LX 7007 – PC via 5P connector usually mounted on the instrument panel will
be possible. After enter on IGC PORT a PC communication via IGC port and IGC standatd connector will be possible.
After PDA activation data exchange LX 7007 – PDA will be possible, suggested program is ConnectLX. Available on
Note!
PDA port is under normal conditions delivering NMEA data sentences to run PDA (SeeYou Mobile, Navigator
Winpilot…) and powers PDA at the same time.
After Enter on Colibri/LX 20, the data exchange with eventually connected Colibri or LX 20 device will be possible
(read/write TP&TSK, read and write of flight info).
Note!
As mentioned before, all three communications ports are physically separated and therefore no data collision problem
could occur, even all devices connected and on.
See Chapter 4 for further details.
2.1.1.6 PASSWORD
Certain system parameters can only be entered through this option. Full details are in the following paragraph, 3.1.2.

2.1.2 SETUP of Options Requiring Access by Password,
After entering the password, 96990, a further 21 system settings are available. During flight the password is not
required, which means that when ENTER is selected in the Password option during flight, the LX 7007 PRO IGC
goes immediately into the following setup menu!
2.1.2.1 AS SELECT (selection of airspace section)
The unit is able to store up to 6 sections (0 up to 5) of airspace, which means practically the whole European airspace.
The unit is delivered fully loaded. Selection of suitable area should be done by pilot using of this menu. After selection
simple press Enter and loading procedure will start automatically. To make airspace visible on PC screen use LXe or
LXAsbrowser PC program.
Note!
To reload a new airspace section (.CUB format only) is done simple by overwriting of actual active airspace using of
LXe PC program, exclusively.
Note!
To prepare custom airspace, in .CUB files, use our special tool for airspace creation and manipulation, called

* Not fully covered county.
Note!
Selection of believable airspace section is possible during the flight too and will take apr. one second.
2.1.2.2 TP (Turn point)
All settings concerning turn points can be done in this menu. The LX 7007 PRO IGC is able to store 600 turn points in
a proprietary format (*.DA4).
TP-QUICK POINT NAME
The pilot is able to store his actual position during the flight by pressing the START button in TP mode in the first
navigation page (see Para 3.2.4.7). These turn points are called QUICK TP and are given the default name AP (actual
point).
Settings:
DATE: OFF stores the position as AP: 12:35. The numbers are the time that the TP was stored.
DATE: ON stores the position with the date and time (28121330 for 28 Dec. 13:30).

TP-QUICK POINT – AUTO
When SELECT: OFF is selected, the actual position will not be selected for navigation
When SELECT: ON is selected, the actual position will be selected automatically and displayed in the navigation page.
NEAR RADIUS
The setting has nothing to do with the setting described in LOGGER. The LX 7007 PRO IGC has a very useful feature
named “Simple task” which is active when a regular task is not set. When the instrument detects that it is within the
Near Radius a turn point in the memory, then that turn point can be treated like a confirmed TP of a simple task. This
gives the ability to provide in-flight statistics for subsequent evaluation without setting a full task. For more
information on this feature see Chapter 3.4, flying with the LX 7007 PRO IGC.
TP-SORT
The LX 7007 PRO IGC is able to sort the turn points either alphabetically or by actual distance from the present
position. If sorted under distance the nearest TP will be the first to be displayed when selecting the turn points.
2.1.2.3 OBS. ZONE (Observation Zone)
This menu defines sector geometry.
The following sectors can be programmed:
•
•
•
•
The START ZONE
The turn POINT ZONE
The finish line (FINISH ZONE)
TEMPLATES
Selecting the TEMPLATES option will program all sectors identically. The only TEMPLATES available are the
900-FAI photo sector and the 500m-cylinder.
The sectors are programmed by defining two angles, two radiuses and the orientation. All settings done here are
“global”, which means the definition is valid for all programmed tasks. Additionally, up to 5 (five) tasks can have
individual sector geometries defined, even for a single turn point of one task. This is done using the “local” setting in
the corresponding task in the task menu. This is a very useful function, when flying an AAT (Assigned Area Task).
These local settings are done in the same way as described below but their incorporation in a specific task is covered in
Para 3.2.4.
Note!:
After programming 'local' sector geometries in specific tasks, if the SETUP OBS. ZONE is used to reprogram
sectors, then all the 'local' sectors will be overwritten with the new global values!
As will become apparent, the definition of sectors, particularly the start zone are subject to continual change. However,
the basic principle of defining the sectors is done as follows:
2.1.2.3.1
START ZONE
To define the start zone, select START ZONE and press ENTER. The following default screen will be displayed:

•
A21:
Orientation ( Options: TO NEXT, RAD.1. TP, and USER VALUE). If TO NEXT or RAD.1.TP are
selected, then AUTO is also displayed not permitting any rotation. If USER VALUE is selected, the
sector can be rotated.
•
•
•
•
•
A1:
R1:
A2:
R2:
First angle
Radius of the sector having angle A1, e.g. 3km for the FAI photo sector.
Like A1, used for creating combined sectors.
Like R1, also used for combined sectors
AUTO NEXT (Y,N) defines the change over procedure on reaching the sector.
At first, this sounds complex, but the following examples will help to clarify the meaning of these settings.
Example 1:
The default setting shown above defines the FAI 90° photo sector combined with a 1km radius cylinder. To modify
these settings to set the FAI 90° photo sector as the start zone, the parameters are modified as follows:
A21 is set to TO NEXT POINT and AUTO as the start zone wants to be orientated symmetrically about the track to the
first turn point.
A1 is 45°, because the bisector of the FAI 90° sector is needed.
R1 is 3km, the radius of the sector.
A2 and R2 are both 0 as a combined sector is not needed .
Example 2:
Program a 180°, 6km Start Zone:
A21: TO NEXT POINT and AUTO
A1: 90° bisector
R1: 3km radius
A2:
R2:
0
0
Note!:
The IGC competition rules of May 2000 specify the start sector for international championships to be a straight line
perpendicular to the first track. This particular option cannot be defined in the LX 7007 PRO IGC and the 180° start
sector is programmed as Example 2 above. The only disadvantage of this is that the LX 7007 PRO IGC will record
a good start when the there is a fix recorded in the zone, whereas in reality a good start is only made when the start
line is crossed in the right direction. The diagram below illustrates this:
Page 15

LX 7007 pro IGC V1.0
Apr.2005
Start 1: not valid with start
Start 2: valid with start
Start 3: valid with start
Start 4: not valid with start
It is therefore recommended that the graphics page is displayed during the start procedure to ensure that a good start is
achieved.
Other possible options for the setting of A21 are:
•
RAD.1.TP: This type of start sector was used in the 1999 World Gliding Championships in Bayreuth. A radius is
drawn from the first turn point, through the start point and a second, greater radius is drawn, thus creating a radial
segment of defined length orientated symmetrically about the start point. The advantage of this system is that a
pilot starting at the extremity of the sector has to fly the same distance to the first turn point as a pilot starting
directly over the start point. This refinement compares with the classical start line where the distance to the first
turn point is increased the further one starts from the centre of the line.
A21:
A1:
R1:
A2:
R2:
RAD.1.TP and AUTO are selected
This setting is ignored; only R1, which defines the length of the segment, is relevant
Set to 6km, the half-length of the segment, giving a total segment length of 12km
Again, this setting is ignored
This sets the length of the two truncated radials that define the edges of the start sector. The setting is
2km in this example
•
FIXED VALUE: This setting allows the bearing of the bisector to be rotated so that it is no longer aligned with
the track to the first turn point. The required bearing is entered in A21 after FIXED VALUE:. This option is
rarely used for start sectors, but is often used for finish zones which may require to be orientated to a particular
runway (see “FINISH ZONE”).

Apr.2005
Note!:
All the examples discussed are intended to explain the programming procedures and present capability of the LX 7007
PRO IGC and do not claim to be comprehensive. Each competition will have its own rules regarding the definition of
sectors, which can be found in the particular competition rules. In case of doubt, the rules defined in the FAI Sporting
Code Section 3 should be used. In most national decentralised championships, FAI-badges, 1000/2000km diplomas
and the Barron-Hilton-Cup, only the 900 FAI photosector is allowed, while for record flights a 1000m startline is used
for recording the start time.
2.1.2.3.2
POINT ZONE
This setting defines the turn point zone, sometimes referred to as the observation zone. The procedure is very similar to
setting the START ZONE except that more options are available for A21.
•
SYMMETRICAL: The axis of the turn point zone is orientated symmetrically about the line bisecting the inbound
leg from the previous turn point and the outbound leg to the next turn point.
•
•
TO PREV POINT: The axis of the turn point zone is orientated towards the previous turn point. This option is
intended for Cat’s Cradle and related tasks.
TO NEXT POINT: The axis of the turn point zone is orientated towards the next turn point. This option is also
intended for Cat’s Cradle.
•
•
TO START POINT: The axis of the turn point zone is orientated towards the start point. Again, this is a Cat’s
Cradle option.
FIXED VALUE: The axis of the turn point zone can be orientated in any specified direction. This is the only
option for which A21 is not set to AUTO.
Example 3:
To specify a turn point zone that is a combination of the FAI 90° photo sector and a 500m radius cylinder:
HDG:
A21:
A1:
SYMMETRICAL
AUTO
45°
R1:
A2:
3.0km
180°
R2:
0.5km
Note!:
It should be noted that when defining combined sectors, the sector with the smaller radius must be designated by A2
and R2 (ie. R1>R2!).

LX 7007 pro IGC V1.0
Apr.2005
Note!:
While the combined sector is used in many National competitions, it is emphasised that for record flights, FAI badges,
1000/2000km-diplomas and for the Barron-Hilton-Cup, only the FAI 90°-photo sector is valid!
2.1.2.3.3
FINISH ZONE
This setting defines the FINISH ZONE or Line. Highlight the FINISH ZONE with the cursor and on pressing
ENTER, a similar screen as for the previous settings is displayed, except that there are only two options for A21:
•
•
TO LAST LEG: The axis of the FINISH ZONE is orientated directly back to the last turn point. This is the
conventional setting for National competition flights.
FIXED VALUE: The axis of the FINISH ZONE can be orientated in a specified direction (see example 4).
Example 4:
It is required to orientate the finish line perpendicular to the runway 06/24, which is not related to the bearing to the last
turn point:
A21:
Select FIXED VALUE and then enter either 060° or 240°, depending on the direction of the final glide. For
example, if the final glide was in direction 240°, then 060° would be entered. The “flat side” of the sector is now
directed back to the last leg and the glider will cross the line to enter the sector.
A1:
R1:
A2:
R2:
90°
1.0km
0 (not programmed)
0 (not programmed)
Note!:
There are many ways to complete a flight. For instance, when completing flights for FAI badges or diplomas, it is
enough to land inside the airfield boundary if the airfield is the finish point. If a remote finish point is specified, then the
appropriate sector must be used. If in doubt, consult the competition rules of the FAI Handbook as appropriate.
2.1.2.3.4
TEMPLATES
Selecting TEMPLATES will give the choice to select one of two options: the 500m radius cylinder; or the FAI 90°
Photo Sector. When one of these templates is selected, then all the sectors of all tasks will be overwritten with the
chosen template without any further confirmation!
Note!:
An exception to this global use of TEMPLATES is when the ZONE function has been already activated. Use of
TEMPLATES in this situation will not change sectors already modified. However, using RESTORE ALL will
change all sectors, both AAT and non AAT, to the settings selected in OBS ZONES for start, TP and finish sectors

2.1.2.4 WARNINGS - Airspace Penetration and Height Warnings
The LX 7007 pro IGC monitors the glider’s position both horizontally and vertically in relation to SUA, and will give
both an acoustic and visual warning prior to the airspace being penetrated. The warning will be activated a specified
number of seconds before entering the airspace – Warn me xxx seconds before, where XXX is the desired input
between 20 and 600 seconds. The default value is 120 seconds. When thermalling, the wind vector is used to calculate
the horizontal warning and the achieved climb rate used to calculate the vertical warning. The warning calculation takes
into account the specified lower and upper airspace heights and no warning will be given if the predicted flight path is
over or under the airspace height limits. The airspace zones for which warnings are required are set by placing a tick in
the appropriate box as shown below.
Note!:
Setting “Warn me 120s before” will warn the pilot that the glider will enter airspace in two minutes provided that the
horizontal and vertical speeds are not changed.
Checked airspace (9) will cause warnings to be given, and vice versa. Airspace is selected according to the ICAO
airspace classifications of A to E. In addition the following other airspace areas can be selected

Example of an airspace warning
The DISMISS warning can be used to deactivate the particular airspace warning for a period of time. Use the
UP/DOWN selection to enter the duration for which the warning is required to be deactivated and press ENTER. The
displayed airspace warning can be DISMISSed from 1 minute to permanent de-activation. DISMISS selections can
subsequently be cancelled by using RESET WARNINGS in the SETUP/Warnings screen. Once the warnings have
been reset, they can be DISMISSed again if the pilot so desires.

Apr.2005
Note!:
Use the DISMISS function to temporarily deactivate individual airspace warnings. All warnings can be reinstated
using the RESET WARNINGS command in the SETUP/Warnings screen.
ALTITUDE warnings can be setup in a similar way and inform the pilot that he is approaching pre-selected altitude
limits.
The warning altitude is always above MSL (Mean Sea Level). The warning will be activated at a specific time before
reaching the altitude limitation. While thermalling, the achieved climb rate is used to calculate when the warning
altitude is going to be reached and similarly, in straight flight, the descent rate is the controlling parameter. Operation
of the altitude warning is the same as for the airspace warning and use of the DISMISS and RESET DISMISS TIME
commands are identical.
Example: altitude warning
2.1.2.5 SETUP GPS
UTC: A UTC offset can be entered at this option, thus ensuring that all time references are to local time rather than
UTC. However, it should be remembered that any offset will have no effect on the time recorded in the IGC flight log;
this will always be UTC
GPS EARTH DATUM: It is not possible to change the GPS earth datum. IGC regulations require that all flight
recorders use the WGS84 earth datum.
2.1.2.6 UNITS
All known units and combinations thereof can be programmed in the LX 7007 PRO IGC. The various units that can be
selected are outlined below:

Example:
An overload of 1.2 means that the current ballasted flight weight is 20% higher than the unballasted flight weight.
2.1.2.7 GRAPHIC
The graphic display of the LX 7007 PRO IGC can show a lot of information and if it is all selected, the display can
become very cluttered. This particularly applies to airspace information and the user should ensure that only relevant
airspace is selected. It should also be remembered that a cluttered display also increases the load on the graphical
processor and slows down the rate at which the screen is redrawn.
SETUP SYMBOL
The LX 7007 PRO IGC graphic display supports two sizes of glider symbol; large and small. Rotate the UP/DOWN
selector to select the corresponding glider symbol. TAIL LENGTH enables a ‘mouse droppings trail’ to be configured
that will display the achieved track for the last x minutes. The trail is disabled if the time period is set to zero.
AIRSPACE
This setting allows the pilot to define which airspace types will be shown on the display. Each airspace type can be set
to ON, OFF or a ZOOM range beyond which the particular airspace will not be displayed. Selecting ON will always
show the airspace regardless of the ZOOM setting, and OFF will never show the airspace. If all airspace is set to ON,
then at large ZOOM ranges, the screen becomes very cluttered and the graphics processor will become overloaded and
slow down. To prevent this happening, the ZOOM range option allows a range to be set, beyond which the airspace
will not be displayed.

If, for instance, 100 km is selected, then the airspace will only be shown when the ZOOM range is 100 km or lower.

OTHER
Transponder mandatory zones
Note!
CTRs are marked using a bold line, so the pilot is able to separate CTRs from other airspace very quickly.
Airspace Customization
A completely new feature of the LX 7007 pro IGC V2.0 is that pilots can customize their own airspace files. Pilots are
able to create areas, or to add and remove particular airspace according to their personal requirements. All
customization is done using the well known “Open Air format” or “Tim Newport Piece format”. Detailed
instructions on customization are described in a separate document, the LxasBrowser manual. This manual is supplied
with each instrument and is also available on www.lxnavigation.si. Restricting the creation of airspace to a dedicated
area where the pilot is usually flying will make the instrument much faster when operating the ZOOM function.
Note!:
All airspace files used with LX7000 v2.0 must have the .CUB extension; it is not possible to load old airspace format
files. The new airspace files can be created and loaded using Lxe build July 15th 2003 or later.
Note!:
To be able to use all the benefits of the airspace graphics and warnings, it is recommended that some time is taken to
study the airspace of the task area. All irrelevant zones should be deleted so that the speed of graphical presentation
remains fast and unnecessary airspace warnings are avoided. Some TMAs are built from many sectors and is
recommended that these sectors are amalgamated into one large TMA definition, if possible. After modification of
.LXW files it is essential that a new .CUB file is built. LXW is a new airspace data base format described in the
APT GRAPHICS (Airports)
Airports are displayed with aerodrome symbols together with their name which can be configured in variety of ways.

APT ZOOM: The airport zoom setting defines the ZOOM range under which the airports will be displayed. For
instance, a 50 km setting will only show the airports when the selected ZOOM range is 50 km or lower; at greater
ZOOM ranges, the airports will not be shown. The permitted settings are: ON, OFF, 5, 10, 20, 50 and 100 km.
APT NAME: The airports are displayed by an airport symbol with the adjacent name or designator as selected below:
•
•
•
ICAO will show ICAO code of the airport adjacent to the symbol
2 char, 3 char, 4 char, 8 char will display the first 2, 3, 4 or 8 characters respectively of the airport name.
NONE, displays only the symbol with no code or name
TP GRAPHICS
The same logic is used for displaying turn points except that some further choices are available.
There are four types of turn points, and each type is designated by a different symbol on the screen (see para 3.2.2).
•
•
•
•
T. POINT This is simply a turn point at which it is not possible to land
AIRPORT This is an airport used as a turn point
OUTLAND This is a turn point at which an outlanding is possible
MARKER This is used to designate a temporary point, such as a good thermal source. It is deleted when the
instrument is switched off
Note!:
If a turn point is designated as OUTLAND, then it will also be displayed in the NEAR AIRPORT screen with the
corresponding symbol. (See para 3.2.2)
2.1.2.8 EDIT PILOTS (Pilot list)
The LX 7007 PRO IGC has the capability of storing up to 30 pilots names, each with their specific configuration
preferences. The list is active as soon as the first pilot has been entered under FLIGHT INFO and copied into the pilot
list. (see para 3.1.1.2 - FLIGHT INFO and para 3.4.1)

Each pilot has the capability, if needed, of protecting his configuration by means of a personal password. This ensures
that a particular pilot's configuration cannot be selected and altered by another pilot. If no pilot's name has been

2.1.2.9 SETUP NMEA
The LX 7007 PRO IGC is capable of outputting positional data sentences in the NMEA format for use by other devices.
The various output configurations are shown below and by placing the cursor on any one and pressing ENTER, the
individual NMEA sentences will be displayed. If Winpilot is used, then WINPILOT should be selected in this option.
2.1.2.10 SETUP PC
The baud rate (speed) of data transfer between the LX 7007 PRO IGC and other devices (PC, LX 20 or Colibri) is
selected from this menu. The default is 19200bps. It is very important that both devices are set to the same
communication speed.
2.1.2.11 DEL TP/TSK
This option allows all programmed turn points and tasks to be globally deleted. If Y (Yes) is selected, then all turn
points and tasks will be deleted and cannot be retrieved. Be careful with this option.
2.1.2.12 GLIDER POLAR
Polars for most gliders are in the library. They are selected by simply rotating the UP/DOWN selector
The polars are defined as a quadratic notation with the parameters a, b, and c. If a suitable polar is not found in the
library, or it is required to define a USER polar, then the program POLAR.EXE, which is contained on the CD
accompanying every instrument, should be executed. The program requires that 3 points on the new polar are entered at
selected speeds (eg. 100 km/h, 130 km/h, and 150 km/h). The program will then calculate the values of a, b and c
which should be noted and entered into one of the two USER polars (rotate UP/DOWN anti-clockwise). Finally, the
name 'USER' should be replaced with a selected polar name as it subsequently appears as the glider type in the IGC
recorder file.

2.1.2.13 LOAD
Each time the instrument is powered up, the ballast settings are set to the minimum. By setting the SWITCH ON
LOAD: SET, the ballast setting will remain at the last setting made on the previous flight and will not be zeroed on
instrument power up.
2.1.2.14 SETUP TE COMP.
The LX 7007 PRO IGC offers two methods of vario TE compensation.
•
•
TE tube
Electronic TE compensation
Note!:
It is important to note that the method of TE compensation is set up when the instrument is installed by the pneumatic
connections made to the TE and Static ports. Changing the compensation type in the setup screen below WILL NOT
change the method of compensation - the pneumatic plumbing has to be changed first (see Chapter 5 - Installation).
If the TE tube option has been installed, then TE: should be set to 0%
There is no further adjustment of theTE is possible; the quality of the TE tube is the only factor.
If the ElectronicTE option has been installed, then TE: should be set to 100%
The TE compensation can be fine tuned during flight with the following procedure. It is essential that this is only done
in smooth air; it is not possible to tune the TE accurately when it is thermic.
•
•
•
Select 100 % and default TEF
Accelerate up to approximately 160 km/h (75 kts) and keep the speed stable for a few seconds
Gently reduce the speed to 80 km/h (45 kts)
Observe the vario indicator during the maneuver. At 160 km/h the vario will indicate about about –2 m/s (-4kts).
During the speed reduction the vario should move towards zero and should never exceed zero (slightly positive
indications are acceptable). If the vario shows a climb, then the compensation is too low, increase the TE%; and vice
versa. Try another zoomie to assess the change and make further adjustments if necessary.
The TEF (TE filter) is the compensation delay. Larger numbers will increase the delay and vice versa. During the first
test is recommended to use TEF 4.
Electronic TE is only effective when the pitot and static sources are co-located and the pneumatic lines to the instrument
are approximately the same length. The best sensor to use is the combined pitot/static Prandtl tube. If problems are
experienced with the electronic TE compensation, then the most likely cause is the glider's static source. The static
source can be checked by plumbing the pneumatic tubes for electronic compensation and then setting the TE: to 0%. In
still air, accelerate to approximately 160 km/h and slowly reduce the speed. Observe the vario indicator. If the static
source is good, then the vario should immediately start to move to show a climb. If the needle firstly shows increased
sink and then moves to a climb, the static source of the glider is unsuitable and there is no way to provide successful TE
compensation electronically. The use of a dedicated and accurate fin mounted pitot/static source such as a Prandtl tube
might help.

2.1.2.15 SETUP INPUT
The LX 7007 PRO IGC has an input for an external speed command switch. Using the external switch it is possible to
switch between SC and Vario manually. Setting the SC INPUT to ON means that closing the switch will cause the
instrument to enter SC mode, and setting SC INPUT to OFF means that closing the switch will select Vario mode.
There is a third option by setting SC INPUT to TASTER and connecting a push button to the input, each key press will
toggle between SC and Vario.
An external alarm to supplement stall warning can be connected to the LX 7007 PRO IGC. The indicated airspeed at
and below which the which the alarm will operate is set under STALL W:. This is also useful in a glider that becomes
very 'draggy' at less than the optimum thermalling speed, such as the LS8. Setting STALL W: speed to coincide with
the onset of the drag bucket will enable optimum thermalling speed to be maintained.
The LX 7007 PRO IGC is supplied with an external temperature sensor. Selecting TEMP. ON will enable temperature
measurement by the sensor. Setting TEMP. OFF permits the user to enter the temperature reading.
There is another input called VARIO PRIORITY. When this input is activated by grounding the appropriate wire, the
unit will change over to Vario immediately. This input wire is set open (not grounded) as a factory default on delivery.
2.1.2.16 SETUP LCD INDICATOR (LCD – Vario Indicator)
The LCD vario indicator is a part of LX 7007 AU. Unlimited number of secondary vario indicators can be connected to
the system using the 485 system bus. The LX 7007 PRO IGC provides 4 different sets of data that can be displayed on
the vario indicators. This means that up to 4 indicators can be set to display different information; any further
connected indicators are simple repeaters. Each LCD indicator is set up from the following menu:
An LCD vario indicator consists of:
•
•
•
Needle
Two numerical displays (upper and lower)
Labels and indicators
These following functions can be set (see next picture):
•
•
•
•
•
Needle
SC Ring
Upper Numeric Display

Lower line, the parameter displayed can be configured in both Vario and SC modes
The labels will automatically be displayed depending on the current function. The BAT warning will be displayed
when the supply voltage is below 11 volts.

Press ENTER and TIME: 11:56:32 is re-activated
2.2.2 NEAR AIRPORT
This option displays the nearest airports, both from the APT database and the TP list, together with those turn points that
have been selected as being landable. The airports are sorted by distance with the closest first. Simply place the cursor
with the UP/DOWN selector on the desired airport and press ENTER. The LX 7007 PRO IGC will change to APT
mode and all navigational features will be available.
Landing Field from TP
Airport from TP
Airport from APT Database
Note!:
The symbol preceeding the name indicates which database the landing point has come from. See the examples
above.
2.2.3 APT Airports, TP Turn Points and TSK Tasks
The three main navigation modes (APT, TP, TSK) are selected by rotating the MODE selector. All three options are
similar and have similar basic navigation data screens accessed by turning the UP/DOWN selector. The first page
shows the basic navigation data (bearing, distance, ground track and ground speed). The airport memory of LX 7007
PRO IGC has a capacity for approximately 5000 airports. The airport data cannot be edited in the instrument; all
necessary updates should be done using a PC. The database used in LX 7007 PRO IGC is a free database. The
database can be downloaded from the Internet using the following addresses:

2.2.3.1 Navigation in APT, TP or TSK
There are five navigation pages; the first one is described below.
Airport name and ICAO
Bearing
Ground track
Wind
Distance
Vario average
Final glide indicator
Altitude AMSL or glide
ratio indicator in SC
MC and Ballast
Course corr. arrow
Note!:
The glide ratio indicator consists of two numbers separated with an E (43E77). The left figures show the average glide
ratio achieved during the last two minutes, while the right figures show the minimum glide ratio required to reach the
APT, TP or finish the task. The over-range indication is '99', which means that the glide ratio is in excess of 99:1.
When flying a task, the minimum glide ratio is calculated on the total distance to the finish line, including all
uncompleted TPs, and any preset safety altitude. This function is very useful when the final glide is being set up around
one or more TPs
The Airport and TP names are normally displayed using 8 characters, but by pressing the START button, 12 characters
will momentarily be displayed. The course correction arrow (Direction Indicator) shows which way to turn (left or
right) to reach the desired APT or TP.
Rotating the UP/DOWN selector will bring up the graphic page. The airports will be shown with both symbols and
short names or ICAO-code. (see para 3.1.2)
Ground speed
The glider symbol remains in the centre of the screen and the map moves under it. To change the displayed range,
simply rotate the ZOOM knob anti-clockwise to increase the range or clockwise to decrease it.
The third navigation page which includes a course deviation indicator (CDI) can be disabled in setup under the PAGE 3
option.

Further rotation of the UP/DOWN selector will call up the fourth, or arrival page.
Time
ETE
ETA
Wind, direction and speed,
minutes since the last update
OAT and battery voltage
ETA (estimated time of arrival) and ETE (estimated time enroute) define the arrival time and the time needed to reach
the destination. Both depend on the settings in the INIT menu. If the glider is not tracking in the direction of the
selected point (track and bearing differ more than 900), both times will be replaced with stars. The age of the last wind
update in min is displayed after the wind vector.
Continued rotation of the UP/DOWN selector will show the last page, where details of the selected airport will be
displayed.
The data is self explanatory except for the traffic circuit, TC details. The pattern height together with its orientation (N
or S) is displayed. The letter I means that the pattern details are not defined.
2.2.3.2 Airport Selection, Team and Wind Calculation
After placing the cursor on the function required and pressing ENTER, a menu appears which offers airport selection,
the team function, or selection of the method of wind calculation.
2.2.3.2.1
SELECT - Airport Selection
There are two ways to select an airport. If the ICAO locator is known, it can be directly entered when the name of the
airport will be displayed.

LX 7007 pro IGC V1.0
Apr.2005
If an incorrect letter is entered, then either press START or rotate the ZOOM selector to move the cursor back so that
the letter can be re-entered.
If the ICAO locator is unknown, then the following method should be used. With the cursor on ICAO, press ESC to
move the cursor to the country. Select the required country with the UP/DOWN selector and press ENTER. Four
stars will now be displayed at the airport name. Using the UP/DOWN selector and ENTER, input the first four letters
of the airport name. All airports with the same first four letters will be available and can be cycled through by use of
the UP/DOWN.
If you input less than four characters, the number of airports that fit the first x letters will be greater. If all four stars are
confirmed with ENTER or after pressing ESC, all airports of the selected state are available and can be cycled through
in alphabetical order.
2.2.3.2.2
TEAM function
This special function has been developed to help pilots flying in a team to locate each other if they loose visual contact.
Both pilots have to select the same destination point (APT, TP or TSK). One pilot then passes his range and bearing to
the selected point by radio. The second pilot then selects TEAM FUNCTION and enters the range and bearing passed
by the first pilot.
Input
Navigation toward companion
Example:
If 347° and 24.1 km is the range and bearing given by the first pilot. After entering the figures and pressing ESC, the
instrument will change to the normal TP navigation page and the data will show the position of the first pilot.
The team function is deactivated after a new APT or TP is selected.
2.2.3.2.3
WIND calculation
The LX 7007 PRO IGC is able to calculate the wind vector. This function is the same in all three navigation modes. A
further method, COMPASS, is available only after an optional compass unit is connected to the LX 7007 PRO IGC
RS485-bus. To change the method of wind calculation, use the the following menu:
Page 34
Download from Www.Somanuals.com. All Manuals Search And Download.
LX 7007 pro IGC V1.0
Apr.2005
Offset input
Method
GSPEED DIF. is the simplest method. The calculation is based on measuring ground speed changes while circling. A
minimum of two full circles are necessary to obtain an accurate wind. The message WAIT2 or WAIT 1 informs the
pilot how many circles are left to get the result. It is very important to keep the speed constant while circling to ensure
that accurate results are obtained. The pilot is able to adjust the wind using manual corrections through the Offset
Input.
POS. DRIFT is the most accurate method. It is based on measuring the drift due to the wind during 6 full circles.
These circles have to be flown accurately and at a constant speed to achieve the best results. WAIT 6 to 1 indicates
how many circles are left until a result is produced.
COMBINATION is using a combination of two methods:
-during the climbing a very realiable method GSPPED DIF. is used and during straight flight an algorithm which
calculates wind after input of GS,GTand TAS. The change over between methods is done automatically.
COMPONENT calculates the wind component (head or tail wind). The calculation is based on measuring the
difference between GS and TAS during straight flight.
FIXED VALUE is not a calculation; it simply allows the pilot to input the wind vector that he wants to use.
COMPASS wind calculation method is available only with the optional compass device. Its use is described in the
COMPASS manual.
2.2.4 TP - Turn Points
The LX 7007 PRO IGC has the memory capacity to store up to 600 turn points. The turn point name can have a
maximum of 8 characters (letters or numbers, no lower case letters and no special signs except * and _ ). The menu
structure is the same as in the APT menu - either four or five pages depending on the set up parameters. A turn point
can be added to the database in one of four ways:
•
•
•
•
Manual input
Copy from APT database
Data transfer from a PC, LX20 or Colibri (*.DA4 format)
Input of actual present position
The procedure is similar to the method of selecting an APT. While in any TP page, press ENTER and a menu showing
SELECT, EDIT, NEW, DELETE, TEAM and WIND will be presented.
2.2.4.1 TP SELECT
To select a turn point simply replace the stars with the first letters of the TP.
IMPORTANT!
The LX 7007 PRO IGC is able to sort the turn points alphabetically or by distance from present position. The method
used is defined in the setup menu. The default setting is alphabetic. If sorting by distance is selected, then the nearest
TP will appear after selection (all stars confirmed with ESC). To search for the TP use UP/DOWN selector and
confirm with ENTER.
It is also possible to select TP by using ZOOM selector. This works exclusively from the first page. To change the TP
simply rotate the ZOOM selector.

Apr.2005
2.2.4.2 TP EDIT
This option allows the pilot to change TP data at any time. The turn points used in LX 7007 PRO IGC have four
attributes. Using attributes, when the turn points are displayed in graphic pages, they will be represented by different
symbols. The four different types of turn points are as follows:
•
•
•
•
T.POINT
AIRFIELD landable airfield
OUTLAND landable outlanding place
MARKER
normal TP, not landable
temporary marker which will be deleted when the instrument is switched OFF
TPs having an airport or outland attribute are landable and are shown on the NEAR AIRPORT page. In front of the
name the pilot will see a symbol indicating what kind of landing place it is (see NEAR).
To start EDIT press ENTER.
Name, attribute, coordinates and elevation can be changed at any time.
2.2.4.3 TP NEW
Place cursor on NEW and press ENTER. The following window will be displayed.
'Y' allows a new turn point to be copied from the APT database. If it is required to enter a completely new turn point,
then select 'N'. A second menu will then be displayed allowing the name, co-ordinates, attributes and elevation of the
new turn point to be entered.
2.2.4.4 TP delete
If this option is selected, then delete confirmation will be requested. If the reply is 'Y', then the turn point will be
deleted and cannot be recovered.
2.2.4.5 TEAM
This function is the same as described under APT in para 3.2.3.2.2
2.2.4.6 WIND
This function is the same as described under APT in para 3.2.3.2.3
2.2.4.7 TP QUICK - Storing of actual position
The procedure is activated by pressing the START button while in the TP-main page only !

On activating the procedure, the present position is displayed with the name defined in one of two forms; AP (actual
position), or TIME (date and time), depending on which option has been selected in the setup (through password) menu.
Once selected, the data can be edited if required. This procedure is useful to store convenient landing places noted
during flight, thermals etc. By default, these points are designated with the MARKER attribute and are therefore
deleted when the instrument is switched off. If these points are required to be stored for future use, then the attribute
should be changed before switching off.
2.2.5 TSK - Task
The LX 7007 PRO IGC can store up to 100 tasks, with each task containing a maximum of 10 turn points (start , 8 turn
points and finish). Selecting and storing a task confers the following benefits:
•
•
•
•
•
•
Accurate task statistics
Simpler navigation
Automatic change over to next TP after confirmation
TSK shown on the graphic display
One further step of ZOOM (full task)
Full AAT support (Assigned Area Task)
Note!:
The final glide calculation in TSK mode is calculated from the present position to the finish point, via all
uncompleted turn points. Final glide to a single turn point or airport is available in the TP or APT modes.
The menu structure is similar to the APT and TP. Graphical data about the start, TP confirmation and finish line is
particularly useful.
Task 01, point 0 (start)
Final glide indicator from
present position to the finish
Altitude (AMSL) in vario mode;
glide ratio to reach the finish in
SC mode
When approaching a TP, a NEAR message is displayed to inform the pilot that he is closing on the turn point. When the
glider enters the observation zone, then the message INSIDE is displayed.

The tasks are numbered from 00 to 99 and the turn points building a task numbered from 0 to 9. Point 0 is always the
start point.
2.2.5.1 TSK - SELECT
All stored tasks can be viewed by choosing SELECT and pressing ENTER. All pre-programmed tasks can now
viewed by rotating the UP/DOWN selector; once the required task is displayed, it is selected with ENTER.
Note!:
Using the ZOOM knob is possible to select tasks by simply rotating the knob. This function is active only from the
main navigation page. After each selection, the total task distance is shown for a short time to help to decide which
task to choose. The total task distance displayed is the sum of the length of all the task legs, plus any additional distance
to reach the start point.
Total distance for apr. 2 sec.
2.2.5.2 TSK - EDIT
The active TSK can be edited at any time, both on the ground and during flight. An already overflown turn point
cannot be edited.
Expected time to complete TSK
The expected time to complete the task is entered in hours and minutes. While this input is not obligatory, doing so will
allow progress to be monitored during an AAT which normally requires to be completed within a specific time window.
Once the task is started, this time runs toward zero and the extended ETA/ETE page will show a lot of additional
information (see flying LX 7007 pro IGC). After a task has been started no input is allowed.
If a turn point is to be inserted, changed or deleted, the desired turn point is selected with the UP/DOWN selector and
on pressing ENTER, a sub menu opens up:
•
•
•
•
SELECT replaces the selected turn point with another
INSERT adds a turn point above the one selected
DELETE removes that turn point from the task
ZONE and MOVE relate to AAT (see below)
Assigned Area Tasks (AAT) - Special Functions
Up to five tasks of the 100 programmable (from 00 to 99) can be designated as AAT. Each individual task point can be
configured for an AAT by using ZONE and MOVE . If ZONE and MOVE do not appear on the sub menu, then five

tasks are already modified for AAT. The AAT modified tasks are active for three flights only. After the third flight
all sectors are set back to the default settings (as defined in SETUP/OBS.ZONES). This feature allows the competition
pilot to make three take offs without loosing the AAT information.
•
ZONE- Using this faction, an individual sector can be defined for each turn point of the task. In the following
example TP 0, the start sector at Thalmaes is defined
A21, A1, A2, R1 and R2 have the same meaning described in SETUP/OBS. ZONES (Para 3.1.2.2)
The final option. AUTO NEXT defines what happens after reaching the programmed zone. When flying “normal”
speed tasks, with AUTO NEXT set to Y (Yes), the LX 7007 PRO IGC will change over to next turn point immediately
after a fix is recorded in the sector. In an AAT this is not very useful, because of big sectors and the need to use the
MOVE function. Setting the AUTO NEXT to N (No) prevents the LX 7007 PRO IGC from switching to the next turn
point when reaching the sector. The pilot must switch over manually by making a short press of the START button.
In the example below an individual sector with 600 has been set at the first turn point and the automatic switch over
disabled.
Example:
Selecting R1 more than 10 km, will set AUTO N automatically.
Start is default N, the TP will automatically change to N after MOVE function is activated.
Note!:
Editing a task and the corresponding sectors can also be done during flight. (See 'Flying with the LX 7007 PRO IGC'
Para 3.4)
•
MOVE In an AAT the sectors are generally quite large, therefore it is reasonable to consider modifying the
task during flight. All AAT′s (max. 5, see above) offer this possibility. Moving of the turn points is allowed
inside the sector only.

Having used MOVE-function, the “new” point has a '#' as the first character (very significant). The sector and the
reference point stay unchanged, but all navigation data is modified corresponding to the new (virtual) point. For
example, the final glide is now calculated around the new point, and the statistics are modified in the same way.
The point is moved using the rotary knobs UP/DOWN (vertical) and ZOOM (horizontal). It is not possible to MOVE
outside the sector. Unless a specified task time (task edit) has been entered, the required speed and remaining time to
complete the task will not be displayed.
The extended arrival page offers the following information:
ETA based on parameter set in
ETE based on parameter
INIT
set in INIT
Remaining distance
Required speed to reach finish
Remaining time, counted down
after task start
The remaining distance is the distance from actual position to the finish line. (If the task has not yet been started, then
this distance includes the distance from the present position to reach the start)
The remaining time is the time left to finish the task, simple count down after task start (active only after input TIME
in TSK edit).
The required average speed is calculated from remaining distance and the remaining time.
Note!:
ETA and ETE are calculated using the parameters defined in INIT under ETA. This is important for competition pilots.
By pressing ESC, the ETA and ETE calculated up to actual TP are displayed for 3 seconds
2.2.5.3 TSK - NEW
Pressing ENTER with the cursor on NEW will select a sub menu asking whether an existing task should be copied. If
N is selected, then the next available task with all points un-programmed will be selected. Sometimes it is easier to copy
an existing task and then amend it; pressing 'Y' allows this to be done.
2.2.5.4 TSK - DECLARE
For all FAI flights (badges, records, and decentralized competitions) the task should be declared before take off. This
procedure replaces the requirement to make a written or photographic declaration.
Note!:
The declaration will not change the instrument functions. The declaration is only the procedure to show that the flight
was planned and declared before take off. All manipulation and functions of the LX 7007 PRO IGC will be the same
whether the task is declared or not. The only difference is in flight validation is that the declaration is recorded in the
.IGC file. Redeclaration during the flight is not possible. Editing the task during the flight, or fly another task will
not change the declaration.
Pressing ENTER with the cursor on DECLARE will display the following sub menu:
Page 40
Download from Www.Somanuals.com. All Manuals Search And Download.
LX 7007 pro IGC V1.0
Apr.2005
All known methods (select, insert, and delete) can be used to change the declaration at this stage. Changing of
declaration will not change the TSK. The take off and start points as well as finish and landing points will usually be
the same. If these points are not identical in your task you have to change either start point or take off point as
necessary.
The normal procedure for declaration is:
•
•
•
Prepare TSK in TSK/EDIT menu (you will need it for navigation later).
Press ENTER on DECLARE, check it is correct and then press ESC to make the declaration.
A short message on the screen will then show the time and date of the declaration
Note!:
If the task declaration procedure has not been made before take off and a believable task has been flown, then an
afterward declaration will be written into IGC file, such a declaration is not valid for official IGC flights (time of
declaration after landing), but can be used for pilot private flight evaluation. Only declarations made before the flight
(manually or via flight info data transfer) will fulfill IGC requirements. A declaration will remain active for one flight
only (power down will not delete the declaration).
2.2.6 STATISTICS
This mode is exclusively used to give the pilot information about his actual flight. There are two levels of statistics;
flight statistics and task statistics. Flight statistics are active immediately after take off and task statistics are activated
once a start is made. (see Para 3.4.4.7)
2.2.6.1 Statistics during flight

These statistics are available after flight. The logbook shows the flights by date with take off and landing time. The
logbook entry will appear approximately 3 minutes after landing and is the signal that the flight is finished and that the
unit can be switched off.
2.2.6.2.2
Statistics after flight
The LX 7007 PRO IGC provides post flight statistics and analysis. To start the procedure, select the flight from
LOGBOOK and press ENTER.
The flown distance will appear if the unit has any task information ( either a programmed TSK or a simple task - see
para 3.4.4.7). If no task information is available, then the TASK NOT SPECIFIED message will appear. Speed is
average speed on task.
After pressing ENTER the pilot is able to recall the route flown and barogram.

To program ZOOM, press ENTER and a small cross will appear in the middle of the screen. Move the cross by
rotating ZOOM and the UP/DOWN selector. Press ENTER when the cross is positioned at the start of the area to be
zoomed. Repeat the procedure for a second cross and place at the end of the area to be zoomed. Press ENTER and the
expanded area will be displayed.
•
BAROGRAM - barogram of the flight
after zoom
The zoom procedure is similar, but there is no cross. After pressing ENTER, a vertical bar will appear which can be
moved (with UP/DOWN) and fixed with ENTER again. The same procedure is used to place the second bar.
2.3 Variometer and Altimeter
All signals from the pneumatic sensors (altitude, speed) are derived from high quality pressure sensors which means that
no flask is necessary. The vario signal is derived from the altitude signal. All signals are temperature compensated
while the vario and speed signals are altitude compensated as well. A custom programmable LCD has been designed to
display the vario information as well as many other parameters. The display is user configurable.
The variometer can be configured to show:
•
•
•
•
range
five time constants
netto vario
5,10 and 2.5 m/s 10,20 and 5 kts
1s to 5s, in addition there are 4 settings of electronic processing for the vario signal
air mass lift and sink
relative vario
shows the lift or sink that would be achieved if the glider was circled at thermalling speed
There are two ways by which the vario indications can be corrected for total energy; electronic TE compensation based
on speed changes with time; and pneumatic compensation with a TE tube. When using pneumatic compensation from a
TE tube, the LX 7007 PRO IGC does not process the signal in any way. The quality of the TE compensation
depends entirely on the location, size and dimension of the TE tube. The installation must be leak-proof.
Note!:
If electronic TE compensation is selected, then the TE port should be connected to a good static pressure source. If
pneumatic compensation is selected, then the TE port should be connected to the TE tube.

2.3.1 Smart Vario description
The LX system incorporates two configurable electronic filters in the circuitry. The first filter adjusts the time constant
and is adjustable between 0.5 and 5 seconds. The 0.5 setting is the fastest while the 5 setting provides maximum
damping.
The second filter, called the Smart Vario, is a dynamic filter and controls the rate at which the vario indication moves.
When set to OFF, there is no restriction on the rate of movement of the vario indication other than the setting of the time
constant filter. When set to 1, the vario indication will not move faster than 1 m/s (2 kts) per second, while when set to
4, the vario indication will not move faster than 4 m/s (8kts) per second. It should be noted that when set to 4, the vario
indication will move four times faster than when set to 1.
Summary:
•
The Smart Vario should not be used in isolation but in conjunction with the setting of the time constant filter.
When the Smart Vario is activated, the time constant filter may need further adjustment to provide optimum
indications.

2.3.2 Altimeter
The altimeter of LX 7007 PRO IGC is temperature compensated from -20ºC up to + 60ºC. The altimeter is calibrated
from 0 to 6000m (20,000ft), but indication goes up to 8000m (26,000ft). The displayed altitude can be based on the
airfield elevation (QFE) or the local QNH which is set in the initialization screen after switching on.
2.3.2.1 IGC barogram recalibration procedure
LX 7007 PRO IGC has an additional pressure sensor for altitude recording. To comply with IGC procedures, this
sensor has no external pneumatic connection. To carry out the baro calibration procedure it is necessary to remove the
instrument from the glider and place it in a vacuum chamber. The procedure is as follows:
•
•
•
•
•
•
•
•
•
•
Switch the instrument ON, and wait some minutes (straight line on the barogram beginning)
Set logtime to 1 second
Place it in the chamber and carry out a short climb to about 1000m
Bring the chamber pressure to exactly 1013.2 hPa
Decrease the pressure by 1000m and hold for about 30 seconds
Continue the procedure to 6000m
Increase the pressure in 1000m steps back to 1013.2 hPa
After reaching ground wait about 3 minutes and switch the instrument off
Leave the instrument minimum 5 minutes off
Read and print the barogram using the Lxe PC program
The barogram will be the last flight in the logbook.
2.3.3 Speed command
Speed command flying based on the McReady theory is a very useful tool to optimize cross country speed. There are
many visual indicators (see LCD Vario). When the instrument changes to speed command mode, the audio will change
and become a director informing the pilot whether he is flying too fast or too slow. In order to reduce confusion
between vario and speed command audio, some special features were developed:

LX 7007 pro IGC V1.0
Apr.2005
•
•
Continuous audio signal in + possible (other kinds of signals can be chosen, see setup)
No audio at correct speed (dead band).
2.3.4 Final glide calculation
The final glide calculator calculates the final glide altitude difference to the selected point (APT, TP). In the task
mode the final glide is always calculated from the current position, round all uncompleted turn points to the goal. A +
indication will inform the pilot that the glider is above the final glide slope and vice versa. The final glide takes into
account Mc setting, wind, bugs and safety altitude.
Note!:
The elevation of the finish point is imported from the TP database into the final glide altitude difference. If this
elevation is incorrect, or is set to zero, and the altimeter is set to QNH, then the final glide will be in error.
It is therefore important that the elevation of the goal is correctly entered in the TP database.
The safety altitude (reserve) input does not affect the glide difference indication which should be 0 m/ft during the
final glide. It simply means that the glider will arrive over the goal at the selected safety altitude.
2.4 Flying with the LX 7007 PRO IGC
To get the best out of the LX7007 PRO IGC, it is important that some preparation is done prior to the flight - trying to
configure the instrument or set up a task while flying the glider may spoil your whole day! Pre-flight preparation will
ensure that the flight will be both successful and enjoyable.
2.4.1 Switching ON and selecting pilot
Pressing the ON/START button will switch on the LX 7007 PRO IGC. The instrument will go through the initialization
phase and stop on the pilot selection. On selecting the pilots name and pressing enter it will continue the initialization
until the Set Elevation menu (entering elevation of the take off airfield) is reached. If the instrument has not previously
been programmed, the pilot name selected will be 'UNKNOWN' and it will go straight to the Set Elevation page.
Single pilot option
If only one person flys the glider, then only his name should be programmed into the instrument through FLIGHT
INFO. The LX 7007 PRO IGC will then show the name of the pilot during the initialization procedure and switch
automatically to the Set Elevation page.
Multipilot option
Up to 30 pilots can be stored in the pilot list of the LX 7007 pro IGC. The first pilot has to be entered into the FLIGHT
INFO and then copied into the pilot list via ADD PILOT TO LIST (Y). Further pilots can be registered under
SETUP / PILOTS with INSERT through Flight Info at any time. Pilots, who want to have their individual settings
saved, should use EDIT (under SETUP / PILOTS) function. In addition to the name, the settings can be protected by a
personal password of up to four characters.
After the initialization routine, all pilots are selectable using the UP/DOWN selector and pressing ENTER. If the
cursor remains on the first letter of the pilot name, it indicates that more than one pilot name is stored and selection
becomes obligatory. The pilot name 'UNKNOWN' is always available and can be selected, in which case the
FLIGHT INFO settings of the last flight will be used. After the pilot has been selected, his last individual settings will
be recalled. If the pilot has protected his data with a password, he must enter it now
Page 45
Download from Www.Somanuals.com. All Manuals Search And Download.
LX 7007 pro IGC V1.0
Apr.2005
The password prevents another pilot from changing the configuration settings that have been set up by the named pilot.
As soon as a pilot has been selected, the LX 7007 PRO IGC switches into the SET ELEVATION menu.
In Summary:
•
If UNKNOWN pilot name is selected, then the FLIGHT INFO settings from the last flight, irrespective of the pilot,
will be used
•
•
If a Pilot without a password is selected, then the FLIGHT INFO settings of the last flight by that pilot will be used.
If a Pilot with a password is selected, another pilot is not able to use his name nor alter any of his stored settings.
Note!:
If a single pilot flies the glider in different configurations, then it is recommended that he uses the multi pilot option
listing his names as 'AN OTHER 15m' and 'AN OTHER 18m' for instance. This will ensure that the correct polar will
be used as it is one of the stored individual settings.
2.4.2 SET Elevation (take off elevation input)
We all know that air pressure changes all the time and it is important that the altimeter is re-referenced before each
flight. After completing the initialization, the instrument requires that the elevation of the present position is entered.
SET ELEVATION:
0185 ft
This setting is obligatory. The instrument will offer the last airport which was on the top of the NEAR AIRPORT list.
If this is OK, the pilot can either simply confirm the offered elevation, or alter it. After setting the elevation, an input of
the current QNH setting is called for. This is not mandatory, but very useful as by entering the QNH will enable the
pilot to subsequently alter it as necessary during the final glide. If the QNH is not entered, it can be ignored by pressing
ESC, but the pilot will then be unable to subsequently alter the QNH setting during the final glide.
QNH:-------mb
Setting QNH
•
•
Rotate UP/DOWN and 1013 mb will be offered, or
Use ENTER and UP/DOWN to enter actual value
Note!:
If the QNH is not set in the startup procedure, it cannot subsequently be changed in flight.

Apr.2005
2.4.3 Preflight check
It is strongly recommended to check all settings in the setup mode access able without the password in case they have
been changed by a previous pilot. All parameters remain unchanged after switching off, with the exception of:
•
•
•
QNH
BUGS
Ballast if not defined with set in setup LOAD
It is recommended that a task is set up prior to take-off. It can either be imported from a PC, LX20 or Colibri set up at
home or during briefing, or entered directly into the instrument.
Note!:
When attempting an FAI Badge Flight, do not forget to make an electronic declaration before take-off using the
'TASK DECLARE' procedure. While declaration during or after the flight is possible, the declaration will not
be valid for IGC or competition purposes!
2.4.4 Performing the flight
It is recommended to switch the LX 7007 PRO IGC on some minutes before the estimated take off time to ensure that
the GPS is locked on, and the obligatory baseline for the barogram in the IGC file is made
If a task (TSK) is to be flown, please ensure that:
•
The correct task is selected. It should be checked (by using the EDIT) that the correct TPs are selected and are in
the correct sequence.
•
•
•
Point '0' is always the start point (not the take off point).
Declare the task, if you want to achieve a FAI-badge, record, or decentralized flight.
Do not forget to change the declaration if your task start point is not also the take off point!
2.4.4.1 Preparing a task
While it is advisable to prepare the task correctly before taking off and thus avoid mistakes made in haste, all the
following actions, with the exception of a FAI Declaration, can also be done during flight.
1. Entering the task
•
•
•
Transfer the task file from a PC, LX20 or Colibri
Copy a similar one and edit it (saving of time)
Enter a new task manually.
2. Check task
•
•
Correct TP´s and in the correct sequence.
That the Task distance is correct.
3. Sector editing
If planning to fly an AAT, the local sectors should be set in the ZONE menu under TASK / EDIT.
Example:
A sector is defined as an area between the radials 300 and 700 related to the turn point, the radius is 20km.
Page 47
Download from Www.Somanuals.com. All Manuals Search And Download.
LX 7007 pro IGC V1.0
Apr.2005
Radial 300
Turn point
Radial 700
For that sector enter:
•
A21 USER VALUE 230° ( 50° + 180°); 50° is the symmetric axis between the two radials (30° + 20° = 50°,
because the complete sector has 40°)
A1 20°, because the sector angle is 40°
R1 is 20km
•
•
•
A2 and R2 are 0
2.4.4.2 Starting a task
If the glider is flying into the start sector and the pilot decides to start the task, the following steps must be followed to
start the task:
•
•
Wait until the message INSIDE appears, indicating that the glider is in the start sector
Press the START button (short press)
Navigation to 1. TP
Before start
After start
A task cannot be started on the ground. Pressing the START button (about 1 sec press), starts the task. A indication
that the task has started is that the navigation data changes to the first TP.
It is also possible to start a task, while the glider is outside the start sector. In this case the pilot has to press START for
a longer time (about 6 sec., but in any case long enough until the TSK navigation data to the first TP appears).
Once the task has been started, it can be terminated at any time during flight and a new start made. If a task has already
been started, press ENTER and the following screen will appear:
Page 48
Download from Www.Somanuals.com. All Manuals Search And Download.
LX 7007 pro IGC V1.0
Apr.2005
Confirming RESTART with Y will restore the actual task. The task is now ready for new start. The restart has no
influence on recorded data or declaration.
2.4.4.3 Automatic swap on reaching a TP using standard task and AAT
By default, the LX 7007 PRO IGC switches over to the navigation data of the next turn point, as soon as a fix is
recorded in the sector of the destination TP. If a turn point cannot be reached, the pilot can manually switch (jump
over) to the next turn point by pressing START for approx. 6 sec. (just watch nav. data). Alternatively, he can delete
the unreachable turn point in the TASK / EDIT(recommended). Neither action has any effect on the declaration!
Note!:
When flying an AAT and using the ZONE function, there are three ways that the AUTO NEXT parameter may be
set to N:
•
•
•
Setting N manually,
Selecting R1 to more than 10 km (N will be set automatically),
Use of the MOVE function before reaching the sector.
In each of these cases the AUTO NEXT parameter is automatically set to ‘N’, and when inside the AAT sector, it
will be necessary to manually change to the next TP by making a short press of the START button. When this is
done, the present position becomes the new TP in the AAT, but the screen will continue to show the old task
structure. However, if the TP has already been MOVEd prior to entering the sector, then pressing the START
button will make the present position become the new TP, and the task will be modified with new # TP. This
ensures that the statistics remain correct, both during and after flight. It is therefore recommended that the MOVE
function is used prior to entering the AAT sector
2.4.4.4 Use of MOVE function
When an AAT is tasked, the pilot has to decide how far into the sector he wants to fly. The MOVE function (see Para
3.2.5.2) modifies the task automatically as the TP is moved, recalculating the distance, ETA, required average speed,
final glide and minimum glide ratio to reach the finish line, taking into account any safety altitude that has been set.
Once the task has been started, the MOVE function is immediately available for the next TP on pressing ENTER,
irrespective of which navigation page is selected.
Note!:
After using the MOVE function, once the glider is in the AAT sector, the pilot is able to change over to next TP simply
by pressing START at any time. The current position will then become the #TP just turned, the task will be modified
automatically and it will be written into the statistics.

Example:
Before press on Start
After
2.4.4.5 TSK END
On entering the finish zone the task stops automatically and a message TSK END will appear. If you want to fly a new
task without landing, then it is necessary to use RESTART and SELECT. If the MOVE function has been used on the
finish point, then it will be necessary to finish the task by using the START button as in the AAT sector.
Note!:
If the finish regulations prescribe entering a cylinder, usually 2 km radius with a base of 200m, then program the finish
zone to the cylinder parameters and set the safety altitude in INIT to the height of the base of the cylinder. When on the
final glide, MOVE the finish point to the border of the cylinder and all it is then necessary to do is to fly the glider to
keep the final glide deviation on 0m.
2.4.4.6 Procedure after landing
IGC Regulations require a straight line (base line) in the barogram at the beginning and end of the flight. For this
reason that it is recommended not to switch off the unit OFF immediately after landing, but to wait a few minutes.
About 3 minutes after landing, the following message will appear on the screen:
Let the message time out a new message will appear saying that the SECURITY algorithm is being calculated. Pressing
ENTER before the screen times out will allow the flight to continue until the unit is powered down.
This message will remain for about one minute and during this time the instrument is writing the security information
that validates the .IGC file. When it is finished, it is safe to switch off the instrument. Confirmation that the procedure
is complete can be checked by selecting the Statistics page: if the logbook is shown, then the procedure is finished.
Never switch off the unit while it is CALCULATING SECURITY. If the unit is accidentally switched off
immediately after landing, it will not cause any problem. When switched ON again, the calculating security message
will appear for a minute or so.

2.4.4.7 SIMPLE TASK
The simple task feature is active prior to a regular task being started. The feature is very useful for pilots who do not
fly tasks but fly from TP to TP (or to an APT). Simple task permits statistics to be stored like a real task and which can
be displayed on the Statistics page and also evaluated by a PC after flight.
Immediately after take off, the current position will be considered to be a start point. On reaching a TP or APT which
has been selected in TP or APT pages, the point will be treated as a TP in a simple task and so on. The radius to define
confirmation of arrival at the TP is set by pilot in „NEAR TP“ (SETUP/PASW/TP). The simple task grows as more
and more TPs and APTs are reached. The flight statistics are the same as a real task except that TSK S shows that no
regular task is being flown.
A new simple task can be started by carrying out a RESTART procedure, and the actual position at the time of the
restart will be the start point in a new simple task.
3 PC, PDA and Colibri/LX20 Communication
Note!
The unit is able to adapt automatically to the baudrate of the partner unit, so no any more problems, if both units don’t
have the same baudrate. A very typical message AUTODETECT will inform about searching for sinhronisation. After
sinhronization is established a CONNECT status will appear.
The LX 7007 PRO IGC is able to communicate with a:
•
•
•
•
•
PC, using LXe, SeeYou, Strepla or CAL programs.
PDA, ConnectLX, Downloader
LX 20
Colibri
Posigraph
Note!
The unit is equipped with three physically separated com ports, which means no data collision even all possible devices
connected and switched on.
The following data can be transferred bi-directional between a LX20, Colibri or Posigraph
•
•
TP and TSK data (DA4)
Flight information
Using the LX7007 PRO IGC in conjunction with a LX20 or Colibri, it is possible to prepare a flight at home or during
the competition briefing, and then when at the airfield use the LX20 or Colibri as a data source for LX 7007 PRO IGC.
Similarly, a task can be programmed in a PC and then transferred to a LX20 or Colibri for subsequent loading into the
LX7000 PRO IGC.
Using of a PDA will do the same, but additionally offers downloading of flights, which means practically no use of PC
in cockpit any more. Flying a competition PDA can be used like data transportation medium Glider – Scoring office,
while the flights stored in PDA includes secure data.

3.1 Communication with PC
After PC communication art was chosen by the pilot, a PC connected to the 5P round connector normaly positioned on
the instrument panel, can be used. All kinds of PC communication can be provided using of IGC port available on the
rear side of he unit. Use standard IGC cables.
Note!:
The LX 7007 pro IGC uses .CUB format of airspace data structure. Ensure that the version of LXe used to load
airspace is build 25 April 2005 or later; never use old versions of LXe to load airspace.
Communication with a PC is via the RS232 serial COM port. If your computer only has an USB port and noreal serial
COM port, then you will need to obtain an USB to serial adaptor, available in every computer shop. To couple the unit
to the COM port, a special cable is supplied with the LX 7007 PRO IGC which terminates in a SUB D 9 pin socket, on
the PC side.
A CD with the following programs is supplied with LX 7007 PRO IGC:
•
•
•
•
LXe Windows program for communication, basic flight evaluation and database management.
SeeYou (1.9) - for task preparation and detailed flight analysis.
LxasBrowser for airspace management and its manual.
ConnectLX for communication with PDA, no navigation functionality required
Using the LXe program, the following procedures can be carried out:
•
•
•
•
•
•
•
Read logger
Read *.da4 (TP and TSK files)
Read flight info
Write *.da4 (TP and TSK files)
Write flight info *.hdr
Write APT
Write airspace (.CUB files only)
LXe will automatically recognize an instrument requesting .CUB file and will offer browse function to find adequate
.CUB airspace file.
Another very useful function of LXe is the preparation of task details such as start, TP and finish sectors. Using the
menu ZONES in Lxe, the details of AAT sectors can also be programmed. All this data can then be transferred to the
LX7000 PRO IGC.
LXe can also be used to update the APT and airspace database. Such updates are free and and no update code is
necessary any more.
Note!
LX 7007 has a memory capacity for maximal 6 .CUB airspace files. To replace one with another simple load a new one.
Replaced will be overtime time the active airspace file. Flying a competition where some special versions of airspace is
issued, overwrite the airspace which you normally don’t use, to prevent missing of airspace data after returning home.
The CONNECT status is achieved as follows:
•
•
•
On the PC run program LXe
On the LX 7007 PRO IGC go to SETUP – TRANSFER / PC
On the LX 7007 PRO IGC press ENTER and wait some seconds until AUTOCONNECT finish and

485 bus and the connectors are marked like 1-1. It is not possible to connect the DU and AU incorrectly as some pins
are removed and some sockets blanked off.
Note!
There is no fuse in the instrument so it is VERY IMPORTANT to use an external fuse (max. 3A). Power supply
cables should use a minimum of 0.5mm² wires (20 awg).
To prevent damages on LX 7000 80mm unit after a short on 485 bus, a fuse of blade type (the same fuses are used in
modern cars and therefore available on petrol stations) is built on the rear side of the unit. After a short happened 57 mm
unit will not work any more, but the reason is not the defect of 57mm unit, but the bowled fuse. Use 3 A fast acting
blade type fuse (violet).

6.1 LX 7007 PRO IGC - Compass Module
Magnet field sensor
LX 485 Bus
6.1.1 General
The compass module is an electronic compass (magnetic field sensor), which was developed for the LX 7007 PRO
IGC. The LX 7007 PRO IGC recognizes the compass module automatically when it is coupled onto the 485 bus.
The only configuration settings needed relate to the compensation procedure. An indication that the compass
module is connected is the appearance of magnetic HDG reading on navigation page 3 of the LX 7007 PRO IGC.
Heading
The compass module not only permits the display of magnetic heading but also permits the calculation of the wind
vector in straight flight. The wind vector is calculated using the triangle of velocities method, where the vectors
of ground speed with track, TAS with compass heading, and the wind vector form a triangle of velocities.

Groundspeed and TRK

LX7007 pro IGC V1.0
Apr. 2005
The angular difference between HDG and TRK depends on the magnitude of the wind vector and is normally quite
small, which means that the measurement has to be quite precise if accuracy is to be achieved. While the GPS data
(TRK and GS) is precise, small inaccuracies in the heading of about 5° can cause errors of up to 25km/h in the wind
strength. This method only works during straight flight and the calculation is stopped as soon as HDG and TAS
change rapidly as occurs when the glider is turning.
6.1.2 Installation of the compass module
The device consists of two parts, a compass sensor and electronic device. The compass sensor should be built
somewhere far from iron parts, which can cause errors in reading. Respect flight direction arrow and install the unit
horizontal. All connections are plug_and_play, so there is no mistake possible. A 485 splitting unit to extend LX
485 bus is included. The box with electronic could be installed on the convenient place in the glider , orientation
doesn’t matter.
6.1.2.1 Where to install:
The compass module should be installed as far as possible away from magnetic, electrical and steel parts (loud
speakers and analogue vario indicators contain strong magnets). Even the mechanical compass should be as far
away from the sensor as possible. Minimum distance is 20cm. As mentioned above, the arrows should be aligned
accurately in the flight direction and parallel to the fore and aft axis of the glider. For a proper installation a plane
area parallel to the horizontal plane is needed.
6.1.2.2 First test after installation:
An external reference compass is required which can either be a prismatic landing compass or a calibrated compass
base on the airfield surface. Using the reference compass, the glider should be aligned in each of the eight main
directions (360°, 45°, 90°, 135°, 180°, 225°, 270°and 335°). Now the glider should be oriented into north direction,
while doing that watch the HDG displayed on Nav.-page 3 of the LX 7007 PRO IGC (do not try to compensate the
compass yet!). If the HDG varies more than ±50, turn the compass so, that the deviation decreases below ±50.
Now turn the aircraft into the other directions and read the displayed values (don’t change the compass position
anymore). If they vary more than ±100 look for another place for the compass module.
6.1.3 Adjusting the compass module:
The compensation of the compass is made in the SETUP menu after entering the password (96990).
pressing ENTER
1. Orientate the glider again to 3600.
2. Set the cursor on N and press ENTER (actual HDG is displayed).
3. Press ENTER again (storing the measured value)
4. Set the cursor on 45°, orientate the aircraft to 45° and again store the measured value.
5. Repeat the procedure for the remaining directions
The compensation table will look similar to that above when you have finished the procedure. Leave the menu with
ESC.
6.1.4 Final test:
Page 68

LX7007 pro IGC V1.0
Apr. 2005
Switch the LX 7007 PRO IGC back to Nav.-Page 3 and check again all 8 directions. The error should now be less
than 10 – 20 (better to have 10 !). If the errors are larger, then one should search for faults in installation or in the
adjustment procedure. When the final test is satisfactory, your LX 7007 PRO IGC is ready to calculate the wind
with the compass method.
Please Note!:
The calibration is specific for your combination of aircraft and compass, which means you cannot transfer the
compass to another aircraft while using the same calibration values.
The parameters are stored in an EEPROM, so they will not get deleted when a memory initialization is performed
or the internal Li-battery is exchanged.
It is recommended to repeat the calibration procedure every year.
6.1.5 Wind calculation during flight
For the wind calculation a finite time is needed to make the calculation. This time (in seconds) is entered in the
INIT menu under WIND/COMPASS. The longer the time the more accurate is the computed wind, and vice
versa.
If the pilot intends to use the wind calculation with the compass module, he has to select in one of the three Nav
Pages the wind menu (just press ENTER when you are on one of the Nav Pages, move the cursor onto WIND and
press ENTER again). Then choose the item COMPASS.
Please Note!:
- The wind calculation with the compass works exclusively in straight flight.
- The calculation is started when the following conditions are fulfilled for at least 5 sec.:
Speed should be constant – It should vary not more than ± 10km/h (6kts)
Flight direction should be constant, variation should be less than ± 5°
The measurement takes that amount of time (in sec.), that was defined in the INIT menu
The result is a new vector wind
If the limits given above are exceeded during the measurement, the procedure will be stopped and restarted as
soon as the conditions are fulfilled again.
The higher the speed, the greater the potential error in the calculated wind.
What the pilot should do during wind calculation:
•
•
•
•
Keep the speed and flight direction as constant as possible
Watch the wind display on one of main Nav pages (lower left corner)
If WAIT is displayed, it means that the conditions for the measurement are waiting to be stabilized
When the measurement is started, a time counter will start counting down (like 15, 14, 13, ...). This is
the time in seconds until the calculation is finished
•
When the procedure is completed without problems, a new wind vector will be displayed.

6.2.1.3 Electronic connection
The LX Remote should be connected to the LX 7007 PRO IGC via a free RS485 BUS port on the back of the
digital vario (9 P female). If there are no free ports because other devices have been connected, then it is necessary
to order a RS485 Splitting Unit to split one input into 3 outputs. When the unit is connected correctly, the LX
Remote will be detected automatically by the LX 7007 PRO IGC when it is switched on.
6.2.2 LX 7007 PRO IGC – Remote K- Stick mounted unit
6.2.2.1 General
All necessary electronic is built into the top of the stick and only for wires should be provided from the handle tube
to the interface unit, this solution makes the installation very easy. Additionally two shielded cables are used for
speed command key and PTT.
Note!
Don’t forget to initialisate speed command input setting to TASTER (SETUP/INPUT)
6.2.2.2 LX 7007 PRO IGC Remote K configuration
There are two units:
•
Leather coated stick with built in electronic
Note!
The stick is delivered in two diameters, 20mm and 24 mm. LS gliders requests 24mm, all other glider types will
accept 20mm.
•
Interface printed circuit board to connecting wires coming from the stick to the LX 7007 485 system bus.
6.2.2.3 Stick handle with keys
The original stick grip should be removed and replaced with the new one. On the top of the new grip there are 9
push buttons. An additional button positioned on the front side is for climb/cruise change over. Both PTT and
climb/cruise buttons are wired separate. All remaining buttons are connected to the built in microcontroller and only
four wires should be connected to the 485 system bus. A very small interface printed circuit board connects four
wires coming out of the stick to the 485 System bus.
Note!
After successfully installation, there is no special setting required on LX 7007 side, a very clear message “REMOTE
DETECTED” during booting routine will inform about presence of this interface.
