1.2 Options
By use of a bus system a wide range of optional interfaces can be easily connected to the basic configuration,
without any significant installation work. The LX 7007 system bus is extended simply by use of 485 splitting
units, which allow plug and play connection of additional devices. The following units can be connected to LX
7007 system bus:
•
•
•
•
•
•
Second seat device
Remote control, for both seats
Flarm option (integral part, not bus connected)
Secondary vario LCD vario indicators (unlimited number)
Electrical compass device
Voice module
1.2.1 Two seater configuration
A unit installed in the rear seat of the glider, is powered and receives all it’s data from the main unit. The
communication between both units is exclusively via 485 system bus. An automatic TP and TSK update will
follow after each power on, the airspace update is done on pilot demand. See LX 7007 D manual for details.
1.2.2 Remote control
An extremely ergonomic lather coated handle which includes 8 push buttons to operate LX 7007 and also two
additionally buttons with open wires. This two buttons can be used for instance as PTT for radio and SC/Vario
changeover command. Using a two seat configuration, two remote units can be installed to control the front and
rear seats separately.
1.2.3 Flarm
Flarm electronics is completely compatible to original Flarm units and an integral part of LX 7007 C DU, if
ordered as an option. All necessary connectors are available at the back of the unit (Flarm update port, Flarm
External Indicator, Flarm antenna), which guaranties the same features as an original Flarm device. It is very
important to point out that the whole system uses only one GPS receiver and therefore offers a low power
solution. One Flarm External display is part of the delivery; extension to second seat is possible.
1.3 LX 7007 Compact C and LX 7007 Compact CB
Both units are derivatives of the LX 7007C & LX 7007 CB respectively. Configuration is the same as for LX
7007C, but there is no in built GPS. The following functions differ on the LX 7007 Compact C and LX 7007
Compact CB:
-no approved flight recorder (there is recorder but it cannot be used as an official IGC file)
-external GPS input plug and play compatible with Colibri, LX 20, Colibri II, Flarm)
-vario electronics built into main unit (not valid for CB)
Unit operation is almost the same as the LX 7007 C, so the same manual can be used. Functions that are
different are marked.

2.3 SETUP
The SETUP is divided into two parts, First level (non system data) and the Second level (system data). Inputs
done in the first level are connected with daily work, the settings done in the second level may change system
characteristics and as such are significant.
Note!
Some settings are so called global settings, not connected to pilot and
second parts are so called local settings. Local settings belong to pilots.
Local settings are accompanied with a man silhouette which to make
understanding more easy.
2.3.1 Main Setup (First level)
All options are selected with the UP/DOWN () switch and can be entered at any time;
The system settings are not affected. The Menu has six items, starting with QNH Reserve
and ending with System which allows entry into system setup.
Note!
TRANSFER offers no inputs, but enables data transfer LX 7007 C to SD
Card, PDA, Colibri or PC.
Once the desired option has been selected, press ENTER to access the sub-menu.
2.3.1.1 QNH RES (QNH and Safety Altitude input)
Input Procedure:
• Use the UP/DOWN selector to choose the item it is required to change
(QNH, ALT.R.)
• 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
ALT.R
: This setting is used to input the altitude reserve or safety altitude. Setting 0 means that no
altitude reserve is set for the final glide. After input the final glide is shifted and the arrival is calculated to the
altitude set in the reserve menu.
Note!
Even after input of a reserve the final glide director will show you 0 glide deviation if the glider position is on the
shifted glide.
Finish line arrival on 200 m
Finish line arrival on 0 m

LX Navigation d.o.o.
QNH:
LX 7007 C
Sept. 30th 2012
Initial status after power on is undefined (- - - - - ). If the pilot wants to adjust the altitude reading due to
pressure changes during the flight, then an initial input of the actual QNH is required. Input is done with
Up/Down and ZOOM. This procedure can only be made on the ground, after take off no initial input is
possible. Following QNH input on the ground, then an update during the flight is possible.
FAI finish: if a badge flight is intended to be flown this menu could
be used to adapt arrival altitude relating to IGC rules. After input
Yes the final glide will be adequately shifted if the start was above
1000m. This is valid only in task mode.
2.3.1.2 PILOT
Input of pilot personal data is possible with this menu.
New input is done simply following an update of existing data and store as a new pilot.
Important!
Setting Competition mode (Y) will reduce selection of navigation modes.
Only Task, TP and Statistics will remain active. To recall standard
configuration, use long press on MC.
Competition mode is linked to the pilot, so if one pilot has activated this
function then the function will not affect other pilots. For future a pilot
list transfer file transfer via SD card is foreseen.
2.3.1.3 LOGGER (Input of flight recorder parameters)
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 kind of FAI
badge flights and also world records.
After selecting LOGGER and pressing ENTER, the following
flight recorder settings are accessible.
Class input means input of the glider class for instance Standard. For safety reason faster recording interval can
be used close to the turn point. All necessary parameters are to be defined in near TP and near radius. IGC
regulations require more frequent recording after a so called “Event function” has been activated (press the
event button long). After event activation the recording interval will follow setting in “Event fix int”. Number of
additional fixes is defined in Num. of fix.

2.3.1.3.1 Vario & SC
Vario & SC allows the setting of the variometer and speed
command. All vario functions are exclusively executed in vario unit
(AU, USB or USB D), but the commands are sent from this menu.

ETA:
• TAB:
• Auto SC:
•
SC Switch:
This sets the time constant of the vario from 0.5sec up to 5 sec; the default setting is 2.0
seconds (higher figures results in a slower reaction of the vario needle)
This setting defines integration period for the averager in seconds; default is 20
seconds
This sets the full scale range of the vario
S.v. means Smart Vario, giving four levels of additionally dynamic damping of the vario
indication the function can enabled or disabled, see chapter 2.5 for details
This setting selects the parameter, VAR (daily vario average) or MC, (actual) 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
This setting defines the width of the audio dead band in speed to fly mode
This option defines the conditions by which the instrument is switched between vario
and speed command
OFF: Switching is possible exclusively by an external switch, connected to the LX 7007
AU or USB unit
GPS: When the GPS detects that the glider is circling an automatic change over to
vario mode will happen after approximately 10 seconds. Detection of straight flight will
cause a change to speed command.
IAS: When the IAS exceeds a pre-set value. The IAS 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)
if external switch is used for vario to SC change over, take note of the following:
The LX 7007 C has a connection for an external speed command switch, which is wired to LX 7007 vario unit.
Using an external switch it is possible to switch between SC and Vario manually. Setting the SC Switch to ON
means that closing of the switch will cause 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 each press will toggle between SC and Vario (obligatory setting when using the LX Remote).

WIND/COMPASS: N.C. means compass option 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 for 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.
2.3.1.4 TRANSFER
Transfer makes it possible to input Turn point data, Airport data
and Airspace data into LX 7007 C. The files should be copied
to an SD card by PC.TP files format should be .cup,
airspace .cub and airports in .af format. Flight info

Straight makes possible to select straight flight wind calculation methods. Available methods are:
-Compnen ; only tail wind or head wind will be indicated
-Compas; is available only if electronic compass device is connected to the system.
Wind calculation is carried out after using of IAS and GS vectors. The process requests
stable straight flight (speed and heading). Comp time input defines how many seconds will take
the calculation (higher values offers better results and vice versa). Comp assist can be enabled
or disabled. After Yes, in the graphic page a small window will open which consists of a dot and
a bar. The window opens automatically after the conditions to measure the wind are fulfilled (stable
speed and heading). The pilot should keep the dot inside the borders as long as the bar is in
progress. In case of not enough stable flight the process will be terminated. In that case the assistant
will disappear and no wind update will follow.

2.3.2.9 TE comp.
LX 7007 C has the capability to offer variometer total energy compensation in two
ways. Selection of compensation method is done after selection the % figure.
000% means total energy compensation when using a TE tube. When using this
solution the unit does not process compensation this depends entirely
on the TE tube and its installation. After an input of a percentage which is other than
zero the special software routines will be activated and will provide an electronic
compensation process. The default value is 100% but this can be varied following
a test flight.
Note!
Electronic and pneumatic TE compensation requires
different connection of tubes.
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 manoeuvre. At 160 km/h (75 Knots) the vario will indicate 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. Repeat this procedure 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 (75 Knots) and reduce the speed.

LX Navigation d.o.o.
LX 7007 C
Sept. 30th 2012
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 initially 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.
2.3.2.10 Altitude warning
In case of an altitude limitation the pilot
is able to set the altitude value which is a top limit.
Three parameters are offered:
-Limit: means upper level which couldn’t be crossed
-Warn before: altitude margin where the warning will start
-Audio warn: yes will execute also an audio sound (didl, didl)
2.3.2.11 LCD Indicator
LCD indicator means vario indicator with it’s mechanical
needle and colour graphic display.
The system is capable to drive also secondary indicators.
Secondary indicators may be simple repeaters or may also indicate
different data sets, it all depends on the indicator number setting.
Vario unit is always addressed as Number 1, secondary indicators
can be addressed from 1 up to four.

2.4.3.3 Turn point Selection
Selection of a turn point uses the same principle as
used by airport. The pilot is able to create some
turn points (up to 50) by hand after input of turn point data.
Such a turn points are called as USER points and
are stored in a separate memory and selectable from
user store.
Note!
User turn points can be edited at any time by using
of the edit function. There is a wide range of turn
point types
2.4.4 Task
Task structure is similar to TP and APT. Basic page is also graphic page followed by three numeric pages which
slightly differ to APT and TP. The most important difference is third page which makes it possible to edit and to
create a new task. Task management is slightly different to LX 7007 pro igc, as there are three types of
task available. Also there is a completely new approach to task start, which is offered as a new function.
2.4.4.1
Task management
Task is a complex procedure which guides the pilot from start point
over turn points until finish line. There are several ways to get a
task into LX 7007 C.
The simplest way is to create new task by hand by use
of turn points which are stored in the LX 7007 C memory and
defined as active (Syst. Setup/Turn points)
There are three stores for task data in LX 7007 C memory. First is
called User (USR xx) and there are stored tasks created by hand
(Maximum 70 tasks).
Second store is built of tasks which are included in TP file which is
activated as Task File in Turn point menu of System Setup.
Such tasks are called Imported (IMP xx). Capacity of imported store
is limited to 20 tasks, if the file consists of more tasks only first 20
will be useable . Imported task file original format should be .cup.
The third store is Declared task store, in fact there can only be one
task stored. The Declared Task data is also written into
flight recorder header. Any task (IMP or USR) can be declared after
execution of Declare command. Declared Task can be also be edited at
any time.
How to select IMP or USR task?
A slightly different task selection procedure has been developed
for the LX 7007 C compared to the LX 7007 pro igc.
After selection of Task mode by rotating the selector,
the task edit menu will appear as the last sub page.
When task edit has been reached, the Zoom selector will
serve as a task selector knob.
Right rotation will offer imported tasks and left rotation
will offer user tasks (tasks created by pilot).
After pressing Escape in task edit (doesn’t matter if User,
Imported or Declared) the unit will move straight to the navigation menu.
For instance if imported task under number
03 has been selected, the task ready for
navigation will be also designated as IMP03
or USR03. It all depends on store from which
the task has been selected.

How to edit task data?
At any point the task (IMP, USR or Declared) can be edited.
Simply put cursor to the point of interest press enter and
edit menu will open. Use Select, Insert and Delete options.
Insert will insert a new point one position higher than highlighted.
That way you can edit IMP, USR and also DECL task data.
Note!
After input of start point the same name will be
offered for finish, if this does not match requirements
a new select should be carried out.
Task declaration
After Declare option in task edit on any User or Imported task has
been used, the actual task data will be copied into DECL task.
Important!
Task data that is included in DECL task is automatically
written into flight recorder, without any pilot assistance.
The same will happen following any change of task data
(made manually), which is done on the ground. Edit of
Declared task editing is also possible during the flight, but
all changes done will not be written into the flight recorder
header, his will remain unchanged.
Declared Task update during flight is possible, but the action will not change declaration in Flight recorder, as
IGC rules do not allow updates during flight.
General rule; if you find DECL designator in the task right upper
corner, you are sure that the task is regularly declared.
Designations IMP or USR show a not declared task.
Understand declaration as an absolutely administrative
process which will write declaration into the flight recorder.
For instance you needn’t start any task, you can fly after
using of APTs or TPs for navigation, but the declaration
will be still valid.
Assigned Area Task
If an AAT is intended to be flown, AAT time should be
set. Use AAT option instead of Speed and input time
after use of the and ZOOM. No limit input describes
a speed task and after time input the task will be
recognized as an AAT.
Zone
By use of the Zone function, required sector geometry
can be adapted to any turn point of the task. The Input
process is the same as described in 2.3.2.6 the only
difference is that the sector adaptation is not global but
local which means it is valid only for the turn point of interest.

Task Start
Task start has been optimised by loading the pilot during the
start procedure keeping work load as low as possible.
The unit is capable of recognising when the Start line is crossed
and to change over to first point automatically.
All the pilot needs to do is to tell the unit that the next line
crossing should be taken as a start.
This can be done by pressing the Start button (short press),
at any position and any time. The unit will change over to ARM status.
Task graphic page has one additiona upper row which is only
active before start. The data of that row helps to the pilot to
execute a good start within the actual rules. There are three
sections in the row. Left section indicates ARM status and
line opening time, B section gives the conditions before start and
the right sections gives the start conditions. Input of all these
parameters is possible in Limitations menu which
will become available after moving to the main graphic page and
enter.
Explanation of terms:
Start time:
input of start line opening time
Before start:
input of altitude* and time limit before start
Start conditions: input of start conditions*
*QNH based input should be done
More about task start see in capture Flying.
Note!
If any start parameter will be out of limits during start line crossing this will not prevent task start.
All mentioned is for information purpose only. A forced start is possible at any time after a long press on start
button. Position of the glider doesn’t matter.
Task Restart
After a task is started a restart procedure can be executed at any
time, Task restart option should be chosen. This option is available
after pressing Enter in main graphic page. After restart an automatic
change over to ARM status will follow.
Move function
After a zone has been given the attribute not Auto next (Auto next not checked),
the move function will become active. The pilot is now able to move the default
turn point Around the sector and thus modify the task distance. This function
is useable after a so called AAT task has been announced.
Move is executable with the and Zoom.
Note!
During move operation you can observe remaining
distance dynamic.
Restart Leg
To reactivate last flown leg a function Restart Leg is offered.
This command is available after pressing enter in the graphic

Variometer
LX 7007 C
Sept. 30th 2012
and altimeter
All signals from the pneumatic sensors (altitude, speed) are derived from high quality digital pressure sensors
which mean that no flask is necessary. The vario signal is derived from the altitude signal. All signals are
temperature and altitude compensated. The variometer can be configured to show:
•
•
range
five time constants
•
•
netto vario
relative 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 acquisition
air mass lift and sink
shows the lift or sink that would be achieved if the glider was circled at
thermaling speed
There are two ways by which the vario units can be corrected for total energy; electronic TE compensation
based on speed changes with time; and pneumatic compensation with a TE probe. When using pneumatic
compensation by use of a TE probe. 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(Pst) port should be connected to a good static pressure
source. If pneumatic compensation is selected, then the TE(Pst) port should be connected to the TE probe.

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.

2.5.2 Altimeter
The altimeter of LX 7007 C 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).
Important!
After correct field elevation input the altimeter indication will always be MSL (Mean sea Level).
2.5.2.1 IGC barogram recalibration procedure
LX 7007 C 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 100m (to start flight recorder)
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
Download the last flight and print the barogram using the Lxe PC program
Restore flight recorder settings
The barogram will be the last flight in the logbook.
2.5.3 Speed command
Speed command flying based on the McReady theory is a very useful tool to optimise cross country speed.
There are many ways of visual indicators. 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:
•
•
Continuous audio signal in + possible (other kinds of signals can be chosen, see setup)
No audio at correct speed (dead band).
2.5.4 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.
2.5.4.1 Final glide after using of FAI finish setting
Mentioned setting can be used after a badge flight is intended to be flown. FAI rulers request arrival above zero
if start has been made above 1000m. The setting is valid until power off.

Flying with the LX 7007 C
To get the best out of the LX7007 C, 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.
3.1 Flight preparation on ground
Pressing the ON/START button will switch on the LX 7007 C.
The instrument will go through the initialization phase and stop
on the elevation selection. The take off airfield elevation should
be entered. After successful input of elevation pilot selection will follow.
The unit will offer elevation of the last nearest airport or land able point.
Adjust if necessary.
Note!
It is recommended to switch the unit ON some minutes before take off, to give time to the GPS receiver to
acquire enough satellites and that the flight recorder will build a base line. Longer time ON, will not reduce
flight recorder capacity due to circular logging during stop status.
3.1.1 Single pilot option
If only one person fly’s the glider, then only his name should be programmed into the instrument through
FLIGHT INFO. The LX 7007 C will then show the name of the pilot during the initialisation procedure and switch
automatically to the Set Elevation page. Don’t confirm SAVE TO PILOT LIST with Y.
3.1.2 Multipilot option
If more pilots are intending to fly the same glider their names
Can be input after editing of an existing pilot name. After any
change a very typical message Create a new pilot will appear
on the screen. After Yes the new pilot will be stored. Some system
settings are connected to the pilot name and are therefore private
settings. To find out which settings are private refer chapter 2.3.
Titles accompanied with a man silhouette shows private settings.
3.1.3 SET Elevation (take off elevation input)
We all know that air pressure changes all the time thus initialisation is
Very important, the instrument requires the elevation of the
present position to be entered.
Important!
If the wrong take off elevation is input then this may seriously
affect your final glide.
This setting is strictly obligatory. The instrument will offer elevation of the airport which was at the top of the
NEAR AIRPORT list before switching off. If this is OK, the pilot can either simply confirm the offered elevation,
or alter it. Altering could be done by and Zoom. Zoom steps are 5 times bigger than using of .
Setting QNH
Actual QNH input is possible in QNH/Reserve menu of Main Setup.
The input is not obligatory, but makes it possible to adjust altitude
due to pressure changes which may occur during flight.
Input of the actual QNH is only possible before take off.
Use or Zoom to input the QNH value.

3.1.4 Preparation of data base
Copy new turn point files from SD card if necessary, use Transfer function. To enable up to three turn point files
use System Setup/Turn point menu.
Activate a new airspace section if necessary use System setup/Airspace. For upload of a new airspace file use
Transfer function at first and then activation.
There is only one section of airport data stored in the unit, so a new airport data base should be entered directly
from SD card.

3.1.5 Preflight check
It is strongly recommended that all settings of following items will be checked:
• QNH/RES
• INIT
• Ballast if not defined with set in setup LOAD
3.1.6 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.
•
•
•
•
a) Entering the task
Transfer the task file (.CUP) after use of an SD card
Activate a new file in System setup/Turn points if necessary
Edit a similar one from IMP, USR, or edit DECL task
Enter a new task manually (USR).
•
•
•
b) Check task
Right TP´s, sequence ,distances between points , bearings and total distance
Check visually task geometry by use of graphic page
Check sector geometry
3.1.6.1
AAT (assigned area task)
Assigned Area Task is in fact a speed task where the task
distance is not strictly predefined. The pilot has limited influence on
task geometry due to bigger sectors which are regularly set.
The pilot decides how deep he will fly into individual sector to
reach optimal task speed. Usually minimum time
spend on task is set, to prevent flying to short tasks.

Sept. 30th 2012
3.1.6.1.1 How to prepare an AAT?
The AAT has the same structure as whichever other task and all known methods to enter are the same as
described. The only exceptions are bigger sectors having specific geometry. To prepare sectors use ZONE
menu for each sector individually.
If the expected task speed seems to be unrealistic,
use MOVE function to adapt TSK distance and consequently
the speed. MOVE function is available also on ground via edit.
During flight, a short cut to move function can be used after Enter.
Note!
Following items are important building up an AAT:
-input of AAT time
-sector geometry creation
3.1.7 Task Start
Task start is a complex procedure, as this action includes
tactical elements and also technical criteria which
must be respected due to rules. LX 7007 C start
support will help both before start and also during
start.
Particularly useful is the Limitations menu where all
the most important parameters can be preset. In addition
everything is visualised, so the pilot has all the important data
on display. All start criteria are fulfilled when there are
no red marked symbols in the upper row.
See also 2.4.4
Example of all green
Example of high speed
Important!
Any red marked parameter will not prohibit start. The start will be executed as normal, even by presence of
warning.
Warning is only for information.
Task restart is possible at any time. After restart, the task will change over into ARM status automatically.
After a turn point was confirmed and there is a need to continue in the sector a Leg restart is offered.
3.2 Flying a task
The most important tip is to prepare the task which is intended to be flown before take off. Special care should
be paid if an AAT is foreseen.
First important manoeuvre is task start. It is recommended to set ARM status some minutes before start as a
minimum. If an unexpected start happens then simply use the Restart function. After restart ARM function will
be active immediately after restart has been executed.
3.2.1 Flying a speed task
Speed tasks have small sectors and therefore Auto next function will become active. Immediately after
reaching of sector the navigation will change to next turn point and the sector will be removed. After a change
over has occurred there is guaranteed minimum one fix inside. If the pilot wants to restart last leg this could be
done by use of the restart function.
3.2.2
Flying an AAT
3.2.2.1 Start
Task start procedure is he same as for speed task. Refer 3.1.7.
3.2.2.2 Inside AAT sector
AAT sectors are in general big sectors which can have different
geometries. LX 7007 will recognize AAT if the sector radius
exceeds 10 km. In case of a smaller sector Auto Next no
should be set by hand.

After using of move the task distance is modified. Move can
be used before reaching of the sector and also inside sector.
After a change over to next point has happened (press on Start button) an automatic move happens and the
task is modified so far that the position of change over point is taken as a new virtual turn point. All statistics
data will change regarding to the new fact.
3.3 Flarm functions
Units equipped with Flarm module which is an integral part of the instrument offers plenty traffic information
features.
Note!
Using the Flarm functions, which are available on LX 7007 C graphic display, doesn’t suspend the use of Flarm
external indicator.
There are two displays which show Flarm data on LX 7007. Flarm objects are shown in graphic page as glider
symbols and also so called “Flarm radar”, can be activated.
3.3.1 Traffic monitor in graphic page

so called Flarm Radar page. The page consist of
glider symbol which is centrally positioned,
concentric circles with two possible info boxes.
Use escape to leave menu. Any gliders in the vicinity are
shown as arrow symbols and not as glider symbols.
Their colour depends on collision risk status. Red marked
symbols means risk of collision. This status is also
synchronized with Flarm display alarm status.
Note!
Sometimes the arrows change into dots. This means
that some pilots are using the so called Stealth
function and therefore send only limited data.
Pilots using Stealth mode active, will see all incoming
objects also as stealth objects. This is done to
stimulate the pilots not use Stealth.

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 avg).
To prevent damage to the LX 7007 80mm unit after a short on
485 bus, a fuse of blade type (the same fuses that are used in
modern cars and therefore available on petrol stations) is built
onto the rear of the unit. After a short the 57 mm unit
will no longer work, the reason is not a defect in the 57mm unit, but
the blown fuse. Use 3 A fast acting blade type fuse (violet).
