LX Zeus v4.0.2
PART ONE – Introduction
1.1 Preamble
Why LX Navigation?
LX Navigation is one of the oldest glider navigation brands. Its founders started experimenting with glider computers way back in the '70-ies and the Company has been working on improving your flight performance ever since.
Throughout the last 40 years or so it has been working on instruments that most pilots will have used at some time. In fact our equipment can be found in almost any gliding club !
Our equipment has always been ground-breaking.
Our motto?
Be the first. Be the best. Be different.
Why Zeus?
Because Zeus is a top of the line product. Crème de la crème.
Used by pilots from all over the world, our instruments offer the best for both cross country soaring and competitions. The LX Zeus is the latest in this tradition.
Devices
We offer a wide range of instruments suitable for both club and competition soaring.
Our systems combine two components:
First, a glider computer (LX Zeus) which is used for calculating and displaying all of the key information used by pilots. This glider computer is the brain of the operation.
The second part of the system is a variometer (Eos, Helios, and Era). Its job is to gather the information which the Zeus uses. The vario has pressure connections as well as the GPS antenna connection which is required for IGC logs.
There is a wide variety of choice for varios and for LX Zeus display sizes.
All our varios are standalone devices which can be used without a glider computer for displaying basic flight parameters such as final glide information, Speed Command (SC) as well as simple navigation. Our varios also have an internal battery which means that your IGC logs do not depend on your glider`s batteries.

LX Zeus v4.0.2
System extensions (second seat unit, remote control (LX Joy), compass, NavBox, MOP, Flap sensor, AHRS ...) are also possible. Everything is connected using a CAN bus (single cable for power and data). All connections are plug and play, which means no specialist is required to install the system.
1.2 Operation
Front panel interface
Communications between the pilot and the instrument is done via two rotary knobs and 8 push buttons.
All buttons and rotary switches have a double push function (short and long press). All buttons are labelled which makes unit manipulation very easy. The top labels are selected with a short press. Bottom labels are selected with a long press. On Zeus 2.8” and Zeus 4.3” there is a 4-4 button arrangement. On other screen sizes the button arrangement is 5-3.
Both rotary knobs are multifunctional as follows:
Default functions:
Volume rotary knob
o Volume adjustment function - scroll o Select (TP, APT, TSK) - short press o Shortcuts - long press
Zoom rotary knob
o Zoom adjustment function – scroll o Open more options (TP, APT, TSK) - short press o Edit NavBoxes – long press
In edit:
Volume rotary knob: bigger steps when selecting values and escape/cancel by pressing it Zoom rotary knob: scrolling and press confirmation
USB/SD
There are two ways of transferring files: either via USB or via SD port. A standard USB-A female port is available on each device (on Zeus 2.8 slim USB keys should be used). The port is exclusively used for data transfer and firmware updates. The micro SD port is only used when Flarm is connected (Flarm Red Box, Swiss Flarm and optionally Flarm Mini Box). The micro SD port is used for direct communication with Flarm, which means downloading flights stored on Flarm, uploading declaration and Flarm firmware updates.
Back panel interface
On the back side of the unit there are the following connectors:
2x CAN bus*  2x User ports  Flarm port (12 V power and data) *  Flarm display output  USB – A port
6 | P a g e
LX Zeus v4.0.2
Note!
Check labels near pneumatic connections on LX Eos/Era, during pneumatic tube connection
process to ensure correct connection.
* CAN bus connects LX Zeus to:
LX Eos (57/80)  LX Era (57/80)  Second seat unit  LX Joy  LX NavBox  LX Flaps sensor  LX MOP  LX AHRS
1.3 Installation procedure (LX Zeus and Eos/Era)
Installation of LX Zeus
The dimensions of larger units (4.3, 5.5 and 7.0) do not match air norm standards (57 or 80mm). A new cut out in the panel is necessary. There are two ways to prepare the panel:
The first option is to buy a new panel from the glider manufacturer and the second is to upgrade the existing panel. The user can also do a panel upgrade and, in that case, basic experience in fiberglass technology will help. (LX Navigation can provide additional instructions on how to rebuild the panel by yourself – just ask!)
Every unit (except the 2.8 inch, which fits an 80mm instrument hole) is supplied with a carbon which makes it possible to make the LX Zeus cut out by hand. If a CNC solution is planned, then please ask for .dwg file.
1.3.1 Installation of LX Eos/Era
The unit occupies one 57 mm or 80 mm standard cut-out. The maximum dimensions of LX Eos/Era 57 are 60x60 mm max and they do not exceed the dimensions of classic pneumatic instruments. LX Eos/Era 80
mm are 82x82 mm max. LX Eos/Era is shallow, which means that there shouldn’t be any problems
installing it as regards space behind the panel.

LX Zeus v4.0.2
At this side the rounded rubber is touching the
back plate of display, do not push it too tight
At this side the rounded rubber is
pressed fully to the plate.
1.3.2 Screen rotation
The screen can be rotated by using password 9109 under Setup > Service > Admin password. The buttons must be rotated by hand. Follow the procedure below:
1. Open the unit (remove all screws and cover)
2. Move rounded rubber to the middle
3. Take out the button and rotate it to the proper position
4. Put button back on blue button (be careful that blue button is inside the black hose)
5. Put rounded rubber back to the first position (be careful with the Rotary knobs as the rubber must not be pushed all the way in)
1.3.3 Connecting LX Zeus with LX Eos/Era
This part of the installation is easy and doesn’t require any specialists. LX Zeus and LX Eos are connected via a CAN bus cable. Connect one end of the cable into Eos CAN bus port and the other into any of the CAN bus ports on the LX Zeus. LX Zeus receives power from LX Eos/Era. All data from and to LX Zeus and LX Eos/Era goes via a single CAN cable.
LX Eos receives power via two power lines, which should be connected to 12V glider power source and ground. The red wire is +12V and blue wire is Ground.
8 | P a g e
LX Zeus v4.0.2
Important!
When LX Eos/Era is connected, the terminator must not be connected to the system, because there
is a terminator integrated in LX Eos. Only one terminator should be used at once.
12 V
Connect supplied power cable with switch to 2-pole connector on LX Eos/Era.
LX Eos/Era and LX Zeus turn ON when the user switches the power ON. This is not the case if LX Eos/Era is a standalone version, which has different hardware and requires a push on the knob to turn ON.
For more information about LX Eos/Era refer to LX Eos/Era manual!
1.4 Update procedure
LX Zeus software is constantly being upgraded. Please contact your local dealer for the latest upgrade. The latest version, together with a change log, is always available on our website (www.lxnavigation.com).
The upgrade procedure is very simple, just follow these steps:
Put the upgrade file (Zeus-x.y.z.kus) onto a USB stick  Insert USB stick into LX Zeus  Turn on LX Zeus (If it is already powered on it should be restarted)  Hold VARIO/FLARM button until the blue window opens  Select upgrade with a push on the Zoom rotary knob  Find the update on the USB stick  Select the file with a push on the Zoom rotary knob  Wait for installation, when an Initial setup screen shows then the update is finished  All devices connected to CAN bus will be automatically updated  In a Double-seater configuration the system may ask if this is FIRST or SECOND seat (confirm
correct one)
In case of Double-seater configuration repeat the whole procedure on the second seat LX Zeus

1.5 Technical specifications
LX Zeus 2.8
This version of Zeus can be installed into any standard 80 mm panel cut out and therefore does not require an instrument panel upgrade. Display orientation is only landscape.
LX Zeus 2.8 Retrofit
Zeus 2.8 Retrofit is the same display size as Zeus 2.8 but differs in hardware. Vario (USB-D) module is inside the main unit and only a vario indicator is needed. The back of the instrument is the same as for LX 5000 (2x 15pin connectors). If the LX 5000 had a 25-pin connector, an adapter for 2x15 to 25-pin is needed, which can be supplied from LX navigation. An old vario indicator can also be used. The attraction of the Retrofit solution is that all wiring remains as is.
LX Zeus 2.8 Retrofit is not available for purchase anymore so this instruction relates only to those pilots who have this system already fitted.
LX Zeus 4.3
This version has a 4.3-inch display with 800x480px resolution and has the following outline dimensions:
83x136x52 mm
LX Zeus 5.5
This version has a 5.5-inch display with 640x480px resolution and has the following outline dimensions:
106x146x52 mm
LX Zeus 7.0
This version has a 7.0-inch display with 800x480px resolution and has the following outline dimensions:
110x190x52 mm

indicator is transparent.)
Limitations (Start conditions)  Map scale  AHRS  Flaps position  Follow indicator (shows position of a Flarm object being followed)  Flarm indicator (used to show Flarm collision warnings. If no warning is available this indicator is
transparent).
Best alternate APT info (shows the pilot the best alternate airfield nearby (APT database) besides
the one being navigated to). If no APT is available this indicator is transparent.
2.1.1.2 NavBox line customization
The bottom row consists of customisable NavBoxes. This means that the pilot is able to create his own configuration. This simple procedure is also available during flight. The user can set different configurations for TP, APT and TSK navigation. It is possible to copy configurations from one page to another. (Done under Setup>Layout). The procedure starts with a long press on the Zoom rotary knob. After the long press a frame appears around the first NavBox. Rotating the Zoom rotary knob positions the frame. When the desired frame position is reached, a short press of the Zoom rotary knob again will open a list of available NavBoxes.

Note!
All settings active at the moment of
new pilot creation under “Pilot” will
be adopted.
To terminate the process, press the Volume rotary knob (“Go back”).
Up to nine bottom rows can be used selectable with 1-4 push buttons. To create a new row simply press 1­4 and a new row will open. The display configuration may consist of one, two or three NavBox rows. See Setup/Layout for details.
2.1.1.4 Header
The header cannot be customized. Only the transparency can be set: go to Setup>Layout. From left to right there is information about:
Current navigation page (TSK, TP or APT)  Current navigation turn-point  Distance and steering information to get to the navigation point  LX Joy status (N = normal, Z = zoom, P = pan)  Battery status  GPS signal status  Current time in selected format (hh:mm:ss)
2.2 Setup
2.2.1 Setup
The setup menu is available after a short press on the push button labelled SETUP. The menu is divided into two sections (Pilot and System settings). System settings are settings that are valid for the whole system and are not pilot specific settings. Pilot settings may vary from pilot to pilot according to individual requirements. Icons with text will help in finding the menu of interest.
Use Zoom rotary knob and rotate it to find the
menu of interest (selected icon is highlighted)
Use push function of Zoom rotary knob to enter
menu
2.2.1.1 Pilot specific settings
The data stored in this part of Setup is pilot specific data. After pilot selection on initial setup, the data of an individual pilot becomes active. All settings are saved to the pilot profile and are active when the pilot is selected (reserve altitude, logger settings, NavBox container, layout settings, task colours etc.) It is possible to export/import user profile settings with a USB stick.
14 | P a g e
LX Zeus v4.0.2
2.2.2 Pilot
The Pilots name and certain personal data can be stored. All stored pilot names will be offered during initial setup and selecting a pilot is mandatory. The system offers a
default user profile with the name DEFAULT which can be used as a default pilot. Furthermore, plenty of empty positions are offered and this can be used for another pilot using the instrument. Some additional parameters can be entered, such as pilot’s weight, default ballast and reserve altitude – all settings are used for final glide calculation.
TDT calculation (task delta time)
This information is shown in a NavBox and presented only if the task time has been set. If task time is set the unit will recognize this task as assigned area task (AAT). The purpose of TDT is to inform the pilot of early or late arrival to the finish line/cylinder.
For TDT calculation one can choose between 4 different options:
• Average task speed is based on current task speed
• MacCready is based on actual based MC value
• Ground speed is based on average ground speed in last 20 seconds
• Combined (default) is based on multiple parameters including: selected MC, wind
sped/direction, polar, bugs, ballast, reserve altitude. This is the recommended method for calculation
AAT calculation
To help the pilot optimize distance inside a sector there are equidistant lines displayed. They are shown inside the active zone. This feature is only available in automatic AAT mode. Flying along these lines will not increase the distance and may lose time on task. Ideally one should fly perpendicular to the lines.
AAT calculation offers two options:
Automatic (default)
This method doesn’t need any pilot assistant at all and the pilot can turn to next turn point at any time without using any commands. Zeus will automatically detect the optimum point in every sector on task. Switching to the next turnpoint is performed by:
o Reaching the line which is crossing the centre of the sector or a moved turnpoint. Reaching
this point will only switch navigation to next turnpoint (for your information). One can still proceed inside this sector and Zeus will find the optimum position inside the sector to start the new leg. A new leg in statistics will start automatically when the optimum point is reached.
o Leaving an active sector. When the glider is more than 5km out of the sector it will switch. This
is done only if there was no automatic switch inside the sector (you did not cross the line over centre of the sector or moved point) or if the next Next TP button was not pressed manually whilst inside the sector.
o Using Next TP button. This command can be used without influencing statistics. It will only
change navigation data.
15 | P a g e
LX Zeus v4.0.2
Manual switching requires specific action in every sector on task. The Next TP button has to be
pressed to switch to next Turnpoint. The position at which Next TP button was pressed is then used for task statistic calculation. In the case of a wrong decision the pilot should use the leg restart function and, when he is ready again, he should then press next TP.
Limiting altitude
Limiting altitude means altitude limit set that will turn on the altitude warning alert.
When this is set, the pilot can choose:
Warn before Warn with audio signal Show dialog when over limit
User defined warnings
The pilot can make user defined warnings, which will give and alert when the conditions assigned have been fulfilled.
To make a user defined warning go to Setup > Pilot select User defined warnings and select “add new”.
1. Then can be defined:
o Conditions check frequency (How
often Zeus checks if the conditions are fulfilled).
o Repeat interval (How often should
the warning be repeated).
o Auto close after… (the length of
time the warning should remain before disappearing).
2. To add the text to appear on the screen as a warning, select Text, and add the desired text.
3. The final step is to add conditions (one or more) which will determine when the warning appears: o Choose a parameter (Choose from -
flight time, air temperature, ballast, air speed, QFE altitude, battery voltage, distance to destination (to current TP or APT)
o Operator (Choose relation to the
reference parameter)
o Value (depending on chosen
parameter)
16 | P a g e
LX Zeus v4.0.2
o Connect condition with (if there is more than one condition, select what conditions are
to be connected with AND or OR)
o When your condition is complete select “Add cond” (if you want to remove it, select
“Clear cond”).
o When finished select Exit
It is possible to edit all user-defined warnings, and to delete them.
Other useful information
User (pilot) settings can also be saved to the USB stick and importing a user done by pressing the buttons: Import user (VARIO/FLARM) and Save user (TSK/MOVE). There is also an option to a set password to each pilot profile to prevent other pilots flying with the same unit and changing the pilot settings (this function was specially developed for flying in clubs). After a press on clear password the password will be removed. To delete a user, simply select delete user.
2.2.3 Audio
This menu defines audio configuration. The audio generator is a part of the vario unit (USB D 60), but settings are stored in LX Zeus. Audio settings do not appear if there
is a LX Eos connected to the system. Instead there is a LX Eos icon where the LX Eos can be set up. For more information please check the LX Eos chapter.
Speed command mode:
• Defines audio in SC. The most commonly used setting is both which means SC will beep in both positive and negative deflections
Speed command volume:
• Defines audio volume in SC; it may be increased or decreased
Vario tone:
• Defines audio in vario mode; the frequencies can be adjusted and also the types of audio; use Test vario after adjustment
Alarm: The audio generator is also capable of generating some alarms (warnings) combining two frequencies. Set frequencies and time intervals and use Test to check.
17 | P a g e
LX Zeus v4.0.2
2.2.4 LX Eos
All settings for LX Eos are done on LX Zeus.
LX Eos settings appear only if LX Eos is connected to LX Zeus, otherwise, there are audio settings for vario (see previous chapter for more information).
If the battery is too empty for the LX Zeus, the LX Eos will still work because it has an internal battery. In this case, settings for LX Eos are set on the LX Eos device (for settings on LX Eos see LX Eos manual)
Warnings
Warnings are used to inform the pilot that some flight related data is outside the desired margins. When a LX Eos detects a warning state, the pilot will get a red warning message box with a description of what is outside the margins.
By ticking the box the pilot can enable audio and Flarm warnings.
o Audio: If disabled, voice warning will not be
generated – the only warning will be visual in message box.
o Flarm: Flarm warning page will be seen only on
the Flarm radar page if this flag is disabled, otherwise it will override any Eos page/menu when a warning is detected.
o Inputs: Must be turned on to enable input port
warnings such as airbrakes, gear etc
o Altitude: Warning when flying above a selected
altitude.
o Stall speed: Warning when the glider speed is
lower than stall speed.
o Vne speed: Warning when speed exceeds Vne.
Audio
Variometer sound frequency can be changed.
Negative frequency means the frequency when the variometer indicates sink of -5.0 m/s (-10 kts).
Zero frequency is frequency when variometer indicates 0.0m/s.
Positive frequency is frequency when variometer indicates climb of 5.0 m/s (10 kts).
18 | P a g e
Inputs
LX Eos offers the possibility of five different user defined inputs. Each input can be set accordingly.
There are seven options to choose from:
None: nothing is connected to the input. SC: the device changes mode from vario to SC
mode
VP: (vario priority) the device goes to vario mode
no matter what the SC is selected to
Event: an event when a flight recorder is activated
and pilot gets a message shown on display
Gear: If enabled under warnings, warnings will be
generated such as gear up/down warnings after takeoff / before landing
Airbrakes: if enabled under warnings, will
generate airbrakes warning if they are opened during takeoff
LX Zeus v4.0.2
The pilot can also select if the switch is working in normal mode or if it is working in inverted mode. Normal mode means that the switch is enabled when contact is closed, inverted means that switch is enabled when contact is opened.
If two or more inputs are the same, the corresponding action will be made when all of them are active (active = switch opened!). The answer as to how to connect switches to external switch interface, and what “active state” is, can be found in the external switch installation section of LX Eos manual.
NMEA
This setup page is used to set what data is sent to a third­party unit connected through Bluetooth or USER port. The pilot can set baud rate (BR) for communication through the USER port or Flarm port.
The pilot can select from: BR4800, BR9600, BR19200, BR38400, BR57600 and BR115200 options.
LX Eos is capable of sending NMEA data to third party units such as PDAs or PNAs. The data is available on the connector marked as USER and Bluetooth port. Five data strings are offered. Selected (check box) NMEA data will be sent over the USER port and Bluetooth:
GPGGA – Global Positioning System 3D-Fix Data GPRMC – Recommended Minimum Specific
GPS/TRANSIT Data
GPRMB – TP navigation info
19 | P a g e
LX Zeus v4.0.2
Note
When Radio option is enabled (KRT2 or ATR833) all other outputs on User port are disabled, but are still present on Bluetooth port.
LXWPx – sentences contain pressure and altitude information in addition to IAS data PFLAx – Flarm traffic info. Data must be enabled, if Flarm data is required on a PDA Radio – Select which radio is connected to Eos USER port. KRT2 and ATR833 were tested and are
supported at the moment. Baud rate on USER port is automatically set to 9600
Pages
The pilot can select which main pages are active on LX Eos. A page is active when its box is checked.
There are five main pages available:
TA (thermal assistance) Flarm TP (turnpoint) TSK (task) GPS info (basic GPS information) AHRS (if AHRS module is connected)
2.2.5 Voice
In the case of LX Eos, or if LX Voice Module is a part of the system, the following settings can be used: If Enable all or Disable all are pressed the pilot can enable / disable all voice commands at once.
Volume:
Voice volume: defines volume of voice messages Vario mixer: defines the balance of volume between Audio and Voice
General Information:
Enable or disable general information about pilot, glider and elevation
Task Information:
Enable or disable information about task, turn point, final glide and time
Warnings:

The indicators page is used for setting up varios with mechanical needles and colour graphic displays. One indicator is defined as a variometer. The system is capable of driving secondary indicators identified as ‘’Number 1’’ through to ‘‘Number 4’’. For LX Eos repeater, connect it to Lx Zeus second seat CAN bus port.
LX Zeus v4.0.2
In general, every indicator consists of a mechanical needle, SC dot, needle status indicator, upper/lower digital indicator, battery indicator and a GPS signal indicator. It is important to point out that the settings should be done separately for vario and SC mode of operation. A radial moving dot serves as a continuous speed to fly indicator; this cannot be changed. On the LX Eos, there is a radial moving arc that serves as a speed to fly indicator. Additionally, there are GS (ground speed) and wind indications, plus some other status icons (Flarm, Bluetooth, etc.) which cannot be changed.
Used terms explanations:
Vario needle: means the needle function in vario mode, alternatives are: vario, Netto*, SC,

2.2.9 Logger
Note!
Pilot and glider data are sent after task Declaration process has been executed. See section Flying.
LX Zeus uses LX Eos and/or Colibri II as an IGC approved flight recorder. Both units collaborate so that all necessary settings can
be sent to all flight recorders connected to the system (LX Eos, Colibri II). No action is required on LX Eos and Colibri II when flight recorders are connected to LX Zeus.
Recording interval is set to 5 seconds by default. Event repetitions are set to 20 and event fix interval to 1 second. This means that when press “Event” button is executed the logger will create 20 records in 20 seconds (one per second).
The extra recording option means that you can select the recording of Ground speed into log file.
LX Zeus v4.0.2
This menu is usable only if LX Eos and/or Colibri II is connected to LX Zeus. If settings are changed, they will not affect Flarm IGC or any other connected Flight recorder.
In a double seat configuration, the second seat pilot is also able to change flight recorder settings. The process is the same as for the first seat.

2.2.11 Wind
LX Zeus is able to measure wind using different methods; these can be selected in the Wind menu. Wind calculation results are shown as a standalone indicator on the
main graphic page and also as a NavBox, if set.
The pilot can choose between two circling methods: one which measures wind during circling flight and the second method using straight flight. The wind calculation is used for numerous calculations (TDT, Final glide, etc.).
2.2.11.1 Circling model
Speed difference is based on the variation of ground speed (GS) using the wind detected whilst in
circling flight. This method is only active during circling. (In straight flight the wind data remains unchanged). The process is started automatically once circling is detected. After two circles the wind indication (direction and speed) will be updated and displayed. This method is based on the ground speed being affected by the wind. GS is, of course, at its maximum with a tailwind and minimum with a head wind and this is used for the GS difference calculation method. To get a result the pilot should do two turns as a minimum, more turns will improve the result. Please note that up to 90 degrees turn or more is required as some time is needed to detect circling status. It is important to keep constant IAS speed during circling. However, other factors are also taken into account to cancel out the fluctuations of airspeed while circling. This wind calculation method is the default and preferred approach.
Position drift calculates wind regarding to position change during circling. Such a method needs
more circles than speed difference (from 4 up to 8). The number of circles should be set in Drift circles option. If both methods, straight model and position drift are selected, the Zeus will give a combined result.
2.2.11.2 Straight model
None: If you select none, you will have the wind from the latest circling method.
Iterative: This method will update the wind in straight flight. It is a special method developed by
LX Navigation and delivers accurate wind measurements by using sophisticated algorithms. With this method, you do not need a compass. The pilot will, however, get good wind speed and direction results. This method does not supplement Head/Tail method and, for best results, a constant IAS is required.
Compass: The Compass system requires the compass module to be connected to the unit using
the 485 bus or CAN bus. Wind calculation is based on the wind triangle method. Under this approach, airspeed, ground speed and wind create a triangle of vectors. A compass device offers magnetic heading, which defines the direction of the airspeed vector. To measure wind using a compass straight flight speed and direction must be kept as stable as possible.
28 | P a g e
LX Zeus v4.0.2
*Compass module is a standalone electronic device, which can be connected to LX Zeus via 485 bus (or CAN bus for newer versions.) The unit delivers the magnetic track to the LX Zeus. However, to get accurate measurements, it is essential to have good compass calibration.
Note:
Compass option is available only if the compass module is connected.
Head/Tail: Shows difference between GS and IAS.
Time for straight flight: Time in seconds that will be taken for one measurement (valid for straight
model). The longer the period the better the result. This is valid only for the compass method and not for the Head/Tail one.
Drift circles: Sets how many circles are required to calculate the position drift.
Compass assistant: Is a special symbol that appears on the display and helps to keep flight
parameters (speed and direction) stable during calculation.
2.2.11.3 Manual wind settings
Set manually - manual wind speed and direction can be set which will be displayed and used for
all calculations.
2.2.11.4 Influence of wind in final glide
The actual wind data (speed and direction) influences the final glide calculation. In task mode the final glide indication is based on the remaining distance over all TPs until the finish (not over turn points already overflown). Wind influence for individual legs is based on actual wind data. Using the Head/Tail method will define wind direction on actual track being flown and this value will be taken into final glide calculation.
2.2.12 Task
The Task menu allows the setting of default zones for quicker and easier task creation.
Under Other settings can be set:
- TDT calculation sets the task delta time calculation method
- AAT calculation sets whether the next TP is set automatically or by hand
- Task start navigation sets the point to which your glider computer will navigate
- Sync with TP navigation sets the same turnpoint for Task and TP menu

If a LX Flap Sensor is connected to the CAN bus it is possible to show the current flap position together with the recommended flap position. Connect the LX CANAD to the CAN bus and insert two wires from the flap sensor to LX CANAD inputs (recommended is IN1). Open the Flaps position settings dialog on LX Zeus. First select the channel where the Flap sensor is connected to LX CANAD (default is IN1). Next move the Flap lever and check that Lever position changes values; this means that the Flap sensor has been properly connected to the system. Now the calibration procedure can be commenced:
- Put the flap lever to aft position (landing or most positive).
- With Zoom rotary knob select the first line.
- Start editing this line:
o Insert position name (up to 4 characters). o Select minimum speed for this flap
position.
o Select maximum speed for this flap
position.
o Press Save screen button to save settings
for this line.
- Move the lever to next position and repeat procedure until all positions have been covered.
- Exit this dialog to send the new settings to LX Flaps Sensor.

2.3.2.5 Total Energy (TE) level and filter
There are 2 ways of providing TE for the LX Zeus; either tube or electronic compensation.
TE level***, set TE compensation style, 0% for TE tube compensation. TE filter***, only valid for electronic TE compensation.
The LX system incorporates a configurable electronic filter. This filter adjusts the time constant and is adjustable between 0.2 and 5 seconds. The 0.2 setting is the fastest while the 5 setting provides maximum damping.
43 | P a g e
LX Zeus v4.0.2
Note!
Electronic and pneumatic TE compensation requires
different tube connections.
In more detail:
Pneumatic compensation
The method used is determined by the % figure set for compensation as well as the way in which the pneumatic tubes are connected. If compensation by using a TE probe is required, then set the % figure at 0%. With this method, the Zeus will not process any electronic compensation and will use only the TE source.
When using pneumatic compensation using a TE probe, the accuracy of the TE compensation depends entirely on the location, size and quality of the TE tube. The installation must be leak-proof.
Electronic TE compensation
Electronic TE compensation is activated when a % setting of more than zero is selected. When this is done a software routine is activated and the system will provide TE compensation. The default value is 100% but this can be adjusted by test flying and-fine tuning the setting to deliver the optimum compensation.
Electronic TE compensation can be fine-tuned during flight using the procedure set out below. It is
essential that this is only done in smooth air as it is not possible to tune the TE accurately when there is a lot of thermal activity.
Select 100 % and default TEF (TE filter). 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 as necessary.
Electronic TE is only effective when the Ptot and Pstatic sources are co-located and the pneumatic lines to the instrument are approximately the same length. The best sensor to use is the combined Ptot/Pstatic Prandtl- type 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 changing the connection of the pneumatic tubes for electronic compensation, and then setting the TE: to 0%. In still air, and as explained above, accelerate to approximately 160 km/h (75 Knots) and reduce the speed. Observe the vario indicator. If the static source is good, then the vario should immediately start to move showing 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 Ptot/Pstatic source, such as a Prandtl tube, will be the only solution in such cases.

2.3.6.2 Crash report
Saving a Zeus system crash report to a USB stick can be done by using admin password "27274".
If a system crash occurs, please send LX Navigation the file.
Once safely on the ground, put a USB stick into the Zeus and use the password in Settings->Service­>Admin password to save crash report to USB key. This will help us to solve the problem and unwanted restarts.
2.3.6.3 Compass calibration
The compass module has to be connected to the main unit via the 485 bus (in the case of a double seater, connect to first seat). The module has to be installed horizontally without any pitch and, once done, enter the compass calibration menu. Position the glider to north and press SET, after that the glider will need to be positioned in all main magnetic directions as seen on the screen. When the glider is aligned correctly press SET. When a window with the sentence ‘Calibration completed’ is displayed, press ‘SAVE’ using the screen button and the system will exit back to the setup menu.
2.3.6.4 AHRS Level adjust (Pitch and Roll)
If the AHRS is not correctly aligned with the glider, then it has to be adjusted.
Changes in pitch in flight are influenced by changes of aircraft mass and changes of airspeed. This reference pitch corresponds to a single airspeed (indicated airspeed actually) and one aircraft mass. When the glider flies faster or slower, or if the glider is heavier or lighter, then the pitch angle deviates from the reference.
Adjustment procedure is:
The internal reference level of LX Zeus instrument
is most likely not to be ideal; therefore, adjustment will be needed. On the ground, put the glider fuselage in the position which best matches the angle of incidence for the reference airspeed. (Do not worry, if this is slightly wrong.) Adjust the Zeus to this level.
Make a test flight with the glider. The aircraft
mass should be as close to the reference mass as possible. Fly at the reference airspeed and observe the pitch indicated by Zeus. Record this pitch on paper. This observed pitch is the error, which needs to be corrected.
52 | P a g e
LX Zeus v4.0.2
Repeat the LX Zeus level adjustment, but now put the glider in such a position (lift or lower nose
or tail wheel) that the pitch on the LX Zeus indicates the same angle as observed during the previous flight. Be careful to keep the wings level. This is now the reference position.
Do not move the aircraft and adjust the Zeus to be perfectly levelled, as follows, under Instrument
Procedure
Instrument procedure:
Go to SETUP / SERVICE / Level adjust
When the glider is ready to have its AHRS calibrated press the on-screen button adjust

3.1.3 Second navigation page (1st subpage)
The second navigation page is divided into two sections. The upper section consists of a vertical profile showing the terrain, glide path distance, airspace, selected TP/APT and cone.
The cone depends on the MacCready (MC) settings. The lower line is a MC setting of 0.0 and upper the line represents the selected MC value. If the glider icon is between the upper and lower lines it means that it is still below glide path for the selected MC, but that it could still reach its destination if a lower MC setting was set. If the glider is below the lower line it is too low and it will not reach the intended destination.
The lower section shows additional APT / TP data such as:
Grass or asphalt runway with directions  Elevation  QNH alt  Flight level  QFE alt  Frequency of the APT  Your current radial  Your current distance from selected APT / TP
The lower section in TSK mode shows a circling log page, wind profile page and a statistics page. Use the 1-4 button to switch between information pages on this subpage.
57 | P a g e
Statistics contain:
Note!
This 2nd subpage can be disabled under Setup>User
Interface.

3.1.4 Third navigation page (2nd subpage)
The third navigation page shows terrain data that is split between a map and an AHRS (artificial horizon and reference system). If the LX AHRS is not connected to the LX Zeus system, only the terrain profile is shown.
The pilot can select full or half screen for 3D view with AHRS.
LX Zeus v4.0.2
3.2 APT mode (navigation to airports)
LX Zeus’ airport database is stored in a special .af file format (LX Navigation airport format). Only one .af can be active at the same time. To transfer and/or select new .af file go to Setup>Transfer>Airports.
APT mode consists of three navigation pages:
main page is map navigation page, 1st page is a subpage with information about selected airport and glide path,  2nd page is a subpage with a map and a 3D view (with AHRS) or vertical profile.
Switch between pages by pressing the SUBP button.
Note: The second subpage (3D terrain) can be disabled (see Setup>User interface).
Airports are marked with a symbol (filled black line means airport with asphalt, a line without fill is a grass runway):

Note!
When using the Name filter, input first letters of the airport name. Use the Zoom rotary knob to scroll and
press it for confirmation. You don’t need to input all
characters, just first two or three and after that you can go on by pressing the Zoom rotary knob. Input of more characters reduces the number of possible airports.
The RWY orientation shown matches the real situation. Extended Airport data is available in the lower section of the second subpage. Pressing the 1-4 button on the second subpage will bring up some additional screens (wind profile, thermal history, etc.).
3.3 How to select an airport?
Airport selection is available from any mode of operation and also from any subpage. Press the SELECT button (short press) and the selected menu will open. Use screen button APT with a short press of TSK/MOVE to start the selection dialogue. If already on the TSK navigation page, give a short press on the Volume rotary knob which is a shortcut to the APT selection menu.
Reachable APTs from the current position are shown in green, non-reachable are labelled red.
Scroll with the Zoom rotary knob to select a filter such as: Country, Name, Distance, and Track or Arrival altitude to reduce the number of offered Airports. If using a sort by distance filter, then it is not possible to use a named filter. Using a country filter will show airports only from the selected country. After the airport of interest is found confirm the choice with a short press on the Zoom rotary knob. The APT screen will open giving navigation to the chosen destination.
59 | P a g e
3.3.1 APT selection from NEAR function
Note!
Selection is limited to 200
nearest points
LX Zeus also offers NEAR function. After a long press on the SELECT/NEAR button, the nearest Landable points and User markers will be offered. The list includes airports from the airport database, turn-points that are declared as landable and Markers.
LX Zeus v4.0.2
3.4 TP mode (navigation to turnpoints)
TP and APT modes are similar in structure. The only important difference is that the navigation is towards turn-points that are stored in the turn-point files. Turn-point files (.cup or .cupx) should be uploaded via a USB stick. (See Setup>Transfer for details.) An almost unlimited number of .cup/.cupx files can be uploaded. Because turn-points can have different attributes the symbols that represent the various types are different.
TP mode consists of three navigation pages (main page is map navigation page, 1st subpage with information about selected airport and glide path, 2nd subpage with a map and a 3D view (with AHRS) or vertical profile. Switch between pages by pressing the SUBP button.
If using .cupx files turn-point images are shown on 1st subpage. A .cupx file can be prepared on a PC or on LX Zeus. To add pictures to turn-points use Select TP menu. On the bottom of the menu is shown the
Upload photo screen button. Use it to transfer pictures from an USB stick to the selected turn-point.
Note: The second subpage (3D terrain) can be disabled (see Setup>User interface).
60 | P a g e
LX Zeus v4.0.2
Note!
Up to three turn-point files can be active at the same time. The activation should be performed under Setup>Transfer. Turn-points included in all three files will be available for navigation. The first file (TP/TSK/Eos) will import tasks. Imported tasks are available in TSK navigation mode.
Extended TP data is available in the lower section of the first subpage. The upper part of the display (1st subpage) is vertical terrain profile.
To activate the screen buttons for the TP options the Zoom rotary knob should be pressed when on TP screen (not at APT or TSK).
3.4.1.1 Edit TP
Press Zoom rotary knob on main TP navigation screen, select screen button Edit TP and a new window called Edit turn point will open.

3.4.1.2 Create User turnpoints
Note!
Type option offers plenty of turn-point designators. The designator defines the symbol that will appear
on the display. A landable point will be shown on the list in NEAR function.
User turn-points are turn-points that are created by the pilot on LX Zeus
Auto TP
If Auto TP is selected, a user TP will be created, with the current position and the current time as its name. To edit an Auto created TP use the Edit TP function.
By hand
Press the Zoom rotary knob on the main TP navigation page and a menu with screen buttons will open. Press Add TP.
The following information can be entered:
Name. Details (not obligatory). Type (grass, field, tower…). Longitude, Latitude. Elevation.

Other input fields may not be highlighted due to the turn-point type being added. Finish the process with Add turn-point.
62 | P a g e
3.4.1.3 Add Marker
Important!
Turn-points without country designators are selectable only when using Country “All” option. This is also valid for user turn-points. Check and correct all files manually before uploading them to LX Zeus.
The philosophy of having a marker is to mark a position, to which the pilot might need navigation assistance (landable field, etc.).
For example, if flying towards a non-landable area, and the last landable field is seen below, then, over this landable field, a marker can be created. It would then be easy to navigate back to that marker, which can be selected at NEAR/TP, or at select TP.
There can only be one marker at a time. If another marker is created, the first one will be replaced by it. The marker can be changed to a regular more permanent TP via EDIT TP. Such a turn-point can be deleted via DELETE TP.
LX Zeus v4.0.2
3.4.1.4 Delete TP
Only user created turn-points and markers can be deleted. To delete a TP the Zoom rotary knob should be pressed, then select screen button DELETE TP and a new window will open. Select the TP by rotating the Zoom rotary knob and confirm it with a short press.
3.4.1.5 Send TP
If Send TP is selected, then the current selected TP will be sent to the second seat (all info about the TP will be sent).
3.4.2 Selecting Turn-points
The selection process is similar to APT. Use SELECT button to start the process and press on-screen button TP. Country, Name and sort by distance, track, arrival altitude filters will expedite selection. Turn-points are displayed by symbols. If on a TP navigation main page the shortcut (press Volume rotary knob) can be used.
63 | P a g e
3.4.2.1 Selection from Near
LX Zeus Near function offers Turn-point selection based on distance. It is also uses a Country filter, use All if you want to select from all turn-points.
3.4.3 Uploading TP photo
It is possible to upload a photo and assign it to a TP.
The procedure to upload a photo:
Insert USB stick Press SELECT button Select TP Choose with the Zoom rotary knob to display the
TP you wish to assign new photo to
Select - Upload photo Choose the photo on USB stick Confirm with a push on the Zoom rotary knob

Note!
Tasks that you want to upload to LX Zeus should be a part of a .cup file and should be selected under SETUP>TRANSFER as
TP/TSK/Eos file. It is very important that you name tasks, otherwise the Zeus won’t recognize them.
3.5 TSK mode (navigation on task)
Every task consists of at least a start point and the finish point. There may be multiple turn-points between the start and finish point. Take-off and landing points can be added (this doesn’t have any influence on task statistics).
3.5.1 Task organization
Zeus has a storing capacity for 100 tasks. 51 tasks can be imported from one .cup file and such tasks are called imported (IMP), the user of LX Zeus can create another 49 tasks. They are called User (USR) tasks. After creating or selecting TSK, the TSK will be automatically declared (and sent to all connected flight recorders).
To delete all existing USR tasks go to Select TSK dialog and then select Clear all. Zeus then asks confirmation and deletes all USR tasks.
3.5.1.1 Task declaration
Declaring the task is an automatic process. After a task is constructed, and exit is pressed (Volume rotary knob), a message on the LX Zeus screen appears: TASK DECLARED! This means that LX ZEUS will start sending the declaration data to connected flight recorders. The declaration is sent to Eos, Colibri II, Colibri X, Era etc. automatically – with all TPs, edited zones, limitations etc...
Eos and Colibri II have the priority and will receive the data first. After this, the declaration data will be sent to FLARM. This process will take about 30 seconds. After the process is finished all LED lights will switch off on the FLARM display and the red POWER light will start blinking. This means that the process of sending task declaration to FLARM is finished.
3.5.2 Task selection
To select a task from the LX Zeus internal task database, the pilot should use the SELECT button and then select the screen button TSK. Use the Zoom rotary knob to select the task of interest. Confirm selected task by pressing the Zoom rotary knob and another window with task details will be shown. Choose the option for the Finish altitude of the task to be less than 1000m below the altitude at which start line was crossed. (as appropriate). The Final Glide will be calculated in correspondence with this altitude, but only if the option is selected.
Exit by pressing the Volume rotary knob twice, or wait until the window closes automatically (if auto close inactivity timeout is enabled).
65 | P a g e
3.5.3 Task creation by hand
To create a new task press TSK/MOVE (short press) or give a short press on the Zoom rotary knob if you are on TSK main navigation page. The task can be created by hand by using NEW or EDIT screen buttons. Edit will make it possible to edit an existing task and New will offer the creation of a new task. Both tasks will be saved under the USER part of the task internal database (if editing an IMP task, it will automatically change from IMP to USR).

Note!
Default task zones can be adjusted under Setup / User Interface. You are able to adjust default start, waypoint and finish zone to make task creation easier.
3.5.3.2 Create and Edit Zones
The ZONE function makes it possible to create any known geometry for turnpoints, start and finish point. The zone can be edited by selecting TSK EDIT/ select TP / ZONE.
After a press on the Next zone or Previous zone buttons, the pilot can change zone settings quickly without any additional actions.
For START and FINISH zones the pilot can select if this zone is a straight line or not.
Auto next option enables the Zeus automatically to switch to the next turnpoint once the sector has been reached. This function is active by default if the sector’s radius is below 10 km (racing task). Larger sectors do not have this option as a default. If Auto next NO is active, MOVE function (for AAT) will become active and that makes it possible to modify the task distance even before flight.
MOVE during an active TSK is also possible. A long press on the push button TSK/MOVE will open a Move window. The ‘custom turnpoint’ can then be moved by rotating the Zoom and Volume rotary knobs. The important information is displayed next to the moved turnpoint (Total distance, Required speed, final glide at MC 0.0 and selected MC).

3.5.4 Task Functions
Automatic and manual starts are possible by using functions ARM and NEXT TP. All functions are available by pressing the Zoom rotary knob when on the TSK navigation page or by pressing the TSK/MOVE button on other pages.
3.5.4.1 Task Start
To start a task automatically use the ARM command which is displayed after a press of the TSK button. Arm means that the task will be started automatically after crossing the start line.
The start line can be crossed multiple times, the time of the last valid start will be used for calculation of statistics. Every valid start is indicated by a green message on the screen.
Under Settings>User Interface>Track/destination settings can be selected whether navigation is aimed at the zone’s center or the zone`s closest point.
LX Zeus v4.0.2
During flight the task can be disarmed. Activation of ARM and DISARM are clearly shown on the display in a message and by an ARMED icon.
If pressing ARM before crossing the start line is forgetten, and the glider is already on the task, then the second option is to press Next TP. Next TP command will change over to next TP every time when activated, regardless of whether the glider is in the sector or not. It will also take the latest start line crossing time, to ensure that task statistics will be correct.
3.5.4.2 Task Restart
After a task has been started a restart can be done at any time. Use the Restart button in the TSK menu. The Restart button will become active once the task has started. After restarting all task statistics data will be deleted and ARM status will become active again making it possible to do another automatic start.

LX Zeus v4.0.2
Note!
Manual changeover is only possible by using the Next TP command. Next TP is always active and it will execute changeover to next TP at any time. Activating this command, when still out of the sector, will degrade statistics data. Solutions: delete TPs that re not required, or extend the zone/sector of TPs.
3.5.4.3 Next Turnpoint
Changeover to next turnpoint can be done automatically or manually. Automatic changeover will occur when Auto next of the individual zone is enabled. If the zone is not Auto next, then the message INSIDE zone will appear. If going to the next turn-point, press TSK button and then press NEXT TP screen button.
Default setting for Auto next:
If R1 is set below 10 km then Auto next is
activated (automatic changeover is enabled).
If R1 is set above 10 km then manual changeover
is necessary.
When flying a task, and when a new TP becomes active, the same TP is set as the navigating turn-point on the TP page.
3.5.4.4 Saving TSK to USB
LX Zeus offers the option to save created or edited tasks to a USB. A USB stick has to be inserted into the USB port. After the creation of a Task, press the Volume rotary knob to get out of edit menu and declare the task. After that, press TSK button and press Save to USB using the screen button. The Task will be saved to the USB stick as a .cup file with current task and all TPs and zones on this task.
3.5.4.5 Clear TSK
When in task editing menu, the whole task can be erased. First press Clear task screen button, then press YES to confirm the choice or NO to terminate the process without erasing the task.

LX Zeus v4.0.2
3.5.4.6 Team Code
Team code is a feature that gives the cabability of visualizing the position of a wingman and yet keep it secure. A short press on the TSK button will bring up the Team code screen and a menu requiring the team code and reference point will appear.
To use this feature there are three NavBoxes available on LX Zeus (TEAM CODE, TEAM BEARING and TEAM DISTANCE).
Before sending a position with the team code all partners should use same reference turn-point. For better indication (more accurate) a reference point which is 50-150 km away from every position in the flight should be chosen (for example the task that is flown should be in the 50-150 km radius of the reference point; if the task is bigger a second reference point should be chosen and entered once an agreed distance has been flown). In flight, when partners are interested about their location, team codes should be exchanged via radio. The pilot`s current code is visible in the Team code NavBox. Partners are able to see bearing and distance of each other in the TEAM BEARING and TEAM DISTANCE NavBoxes.
The feature works on the principal of the polar coordinate system. The baseline condition is having the same reference point. When this is chosen, LX Zeus calculates distance and bearing from this reference point to the pilot’s location and codes it into Team code. The first two characters mean the angle and the last two the radius from the reference point. When this information is given to a partner with the same reference point chosen, LX Zeus can calculate direct bearing and distance to the other partner. The process works in both directions between partners.
3.5.4.7 Limits
Here are the task start conditions that can be selected. It is possible to:
Define gate time Define before start:
o Below altitude o Below time
Define start conditions:
o Start altitude o Start ground speed
For the explanation of these terms read more under chapter Start Conditions/Limitations
3.5.5 MOVE Function (during flight)
When flying an AAT, big sectors are set and therefore the pilot has to decide where to turn to the next turn-point. The MOVE function helps the pilot to find an optimum solution. After a long press on the TSK/MOVE button the MOVE function will become active. Use Zoom and Volume rotary knobs to move the turn-point. All task relevant data that is affected by the move is displayed next to the zone.
During straight flight, when far from the zone, the track will appear in the zone in the MOVE function. When the glider is in the zone, the real-time picture (glider with its track), will also be shown on the MOVE dialog.
71 | P a g e
LX Zeus v4.0.2
3.5.6 Task Zoom
By rotating the Zoom rotary knob to the left the Task zoom will be activated which will show the whole task on the screen. Task zoom will show all turn-points (moved and modified) with airspace. Task zoom is not visible while flying, only on the ground.
72 | P a g e
4 Airspace Management
Airspace on LX Zeus can be managed by the pilot to achieve the optimum relationship between loading the display and its readability. Too much information will reduce the readability of the display.
1.1 Basic airspace settings
Settings are available under Setup > Airspaces. The user can select warnings and appearances related to the zoom level.
4.1.1 Hide airspace above
The airspace sections that are much higher than the altitude of the glider are not relevant. Disabling them will significantly reduce the density of information on the display. Use Hide airspaces above airplane to define the altitude margin that considered to be required for a safe flight.
LX Zeus v4.0.2
4.1.2 Other settings
Hide above QNH altitude allows a selection of the QNH altitude above which the airspace should be hidden.
Horizontal and vertical distance warnings can be set also in this section. LX Zeus will warn a user at a predefined warning distance. Default settings are 100m vertically and 2 km horizontally.
Warning timeout at takeoff allows a choice as to how long after the take-off there won’t be any airspace warnings.
4.1.3 Define appearance of airspace
related to zoom level
Zoom levels can be selected at which different airspace types will be visible. Use the Show on zoom function to define to which zoom level the airspace type is to be visible on the display. Two extreme situations are described with always and never. Factory default settings for all airspace types are always.
73 | P a g e
4.1.3.1
If set to disabled ( ) the airspace info box for this airspace type will not appear on the screen. Setting checked ( ) will produce airspace info box information.
The airspace info box is an indicator on the main screen. The pilot is able to move/resize the box and also to customize colours. This can be done under Setup >
Layout.
The airspace info box contains airspace name, horizontal and vertical distance and is by default positioned in the upper section of the display. The nearest point to entering the airspace becomes visible on the display. As long as the warning isn’t critical the text colour is blue.
Airspace is displayed at 1st subpage in different colours (yellow and red). Airspace is also seen in a 2nd subpage, where the page is split between a map and a vertical profile (but only if AHRS is not connected to the system).
LX Zeus v4.0.2
Explanation of airspace info box
The picture shows that the glider is in the CTR MARI airspace. It shows that the glider is horizontally 11.2 km inside and vertically 82 m outside. The red warning confirms that the glider is inside, the yellow that it is close and the green warning means it is outside.
74 | P a g e
4.1.4 Disabling airspace sections
Edit airspace dialog after a press on
EDIT button
During flight, airspace warnings may appear on the screen (picture on the right). Pressing on one of the screen buttons can easily disable the warning. Airspace warnings can be disabled for specific amounts of time (5 minutes, 10 minutes, 30 minutes, 1 hour, 3 hours or for whole day).
Airspace can also be disabled whilst on the ground. Press SELECT button to open airspace dialog. Airspace is sorted by distance. In the upper part of dialog there is a list of airspace with name of the airspace, horizontal distance and operating altitude from and to in meters/feet and also as a Flight level. The bottom part of dialog shows airspace around the glider. The colour of the currently selected airspace is blue.
LX Zeus v4.0.2
Different airspace can be selected with the Zoom rotary knob. By rotating the Volume rotary knob the zoom level can be changed. After a press of the Zoom rotary knob or a press on the EDIT screen button, a dialog with additional options for selected airspace will appear, as follows:
Airspace type  Airspace class  Disable airspace until specified date
A screen button DISABLED ONLY will show only disabled airspaces.

5 GPS signal management
Note!
LX Zeus can adapt baud rate to any value between 4800 and 38400 automatically, so baud rate of GPS source connected to Flarm input does not matter as long as it is in the range (4800-38400).
Note!
Colibri II is powered from LX Zeus. All settings and declarations are sent from LX Zeus to Colibri II/Eos/Era/MOP/Flarm. There is no need for any additional setup on Colibri II/ Eos/Era/MOP/Flarm.
LX Zeus has three GPS signal inputs, they are on the back of the unit. The following devices can be connected:
Colibri II Flarm or any device with NMEA output LX Eos/Era via CAN bus
5.1 Colibri II socket
The Colibri II socket can be used only to connect a Colibri II unit. It delivers power (5V) for the Colibri II and sends/receives data directly without any data interface. The communication is bidirectional. Every unit equipped with Colibri II is supplied with a suitable connection cable (USB mini to 6-pin RJ11).
5.2 Flarm plug
A Flarm marked input is a plug and play solution for connecting any unit that has 6-pin RJ11 IGC compatible connector. This port also delivers 12V.
LX Zeus v4.0.2
The following units can be connected without any additional adaptor:
Colibri, LX 20 – 2000, VL, LX Flarm RB, LX Flarm
MB, Flarm (Swiss)
5.3 LX Eos – CAN plug
LX Eos/Era connects to a CAN port, it doesn’t matter which one is used. If an Eos is connected to the system, please check that there is no CAN terminator used on the CAN bus (CAN terminator is already built-in to the inside of a LX Eos/Era device).
5.4 GPS signal for navigation
All GPS inputs are used on LX Zeus. This means that LX Zeus is supplied with valid GPS signal as long as at least one connected GPS receiver delivers valid data. A symbol positioned in the right upper corner of the display shows GPS signal status:
red GPS BAD green GPS OK white symbol with means no GPS data is present
76 | P a g e
LX Zeus v4.0.2
6 LX Zeus and LX Eos/Era
LX Eos/Era and LX Zeus together create a very compact and robust system. They are connected with a single CAN cable (use CAN port on both devices).
All the data and power supply is transmitted through this cable. LX Zeus and LX Eos transfer all the necessary data from one to another. When LX Eos/Era is connected to LX Zeus all settings for LX Eos/Era are made on LX Zeus and transferred to LX Eos/Era.
When LX Eos/Era and LX Zeus are connected, the setup screen cannot be seen on LX Eos/Era, because the setup is done on LX Zeus. If the main power supply fails (ie.: Zeus does not work anymore), and it is still in flight mode, LX Eos/Era will keep working as it has an integrated battery with about a three hour duration. In such cases the Setup page will appear on LX Eos/Era and there is an option to set all important parameters on LX Eos/Era device. To see LX Eos/Era setup structure, please check LX Eos/Era manual.
LX Eos/Era has an integrated ENL sensor.
6.1 LX Eos/Era power management
Connect the main power cable with a switch to LX Eos/Era. Immediately after LX Eos receives power, the LX Zeus will automatically switch ON, without any pilot interaction. When the main power from LX Eos/Era is cut, LX Eos/Era will start a 3 second countdown before it turns OFF. LX Zeus and other CAN devices are turned off immediately. When for some reason the main power supply is lost during flight, LX Eos/Era will continue to record the flight for about 3 more hours.
The internal battery inside LX Eos/Era is automatically charged when there is a 12V power supply and this means that it is always available to provide internal backup power supply for LX Eos/Era. The charging process of an empty battery takes around 2 hours.
77 | P a g e
6.2 LX Eos/Era – Zeus interaction
Important!
Any change on task will immediately update LX Eos’ internal task. As long as on ground (not flying),
the new data will be written into declaration of LX Eos flight recorder. The same will happen with pilot data. After take-off, the task synchronization will start working but the declaration in the flight recorder will remain unchanged (IGC rule).
After connection between LX Eos/Era and LX Zeus is established, both units will start to communicate over the CAN bus. The connection is established automatically without any pilot interaction.
6.2.1 Commands and declaration transfer to LX Eos/Era
Every time the system is turned on the following data is sent to LX Eos/Era:
Pilot data: After initial setup on LX Zeus (also
pilot 2nd name in the event of a double seater configuration)
Recording interval Other data related to flight recording with
recording (Event repetition…)
Selected task: the task will become declared Active turn-point file (.cup in TP/TSK/Eos slot) Active turn-point navigation Other vario settings
LX Zeus v4.0.2
A long press on the EVENT button, will send the event command to LX Eos/Era. The event command can be sent also from a second seat.
For more information about LX Eos/Era system, refer to LX Eos/Era manual.

LX Zeus v4.0.2
Password 99999:
Password 99999 will delete all flights from Colibri II and LX Eos
Important!
Any change of task, will immediately update the Colibri II internal task. As long as it is on the ground
(not flying), the new data will be written as a new declaration to the Colibri II flight recorder. The same will happen with pilot data. After takeoff the task synchronization starts working but the declaration in the flight recorder will remain unchanged (IGC rule).
7 LX Zeus and Colibri II
LX Eos and LX Zeus together create a very compact and robust system. All flight recording related settings are sent from LX Zeus and, in their relationship, LX Zeus is the master and Colibri II is a slave. This is why it is possible to install Colibri II in an inaccessable place (under/inside instrument panel), as long as the Colibri II position ensures good GPS reception. It is essential that the Colibri II has version 1.93 or higher installed.
Colibri II has an integrated ENL sensor.
7.1 Colibri II power management
Once the LX Zeus receives power, the Colibri II will automatically switch ON without any pilot action. After landing the Colibri II will remain ON as long as LX Zeus is powered. When LX Zeus is switched OFF, Colibri
II will work for a limited time and switch OFF after approximately 5 minutes. Colibri II is permanently charged from LX Zeus and this ensures that the Colibri II battery will be always full. When, for some reason, battery power is lost on LX Zeus during flight, Colibri II will continue to record the flight for up to 15 hours.
7.2 Colibri II – LX Zeus interaction
Once a connection between Colibri II and LX Zeus is established both units start to communicate using a special LX protocol. The connection is established automatically without any pilot action.
7.2.1 Commands and declaration transfer to Colibri II/Eos/Era
Every time the system is turned on the following data is sent to LX Eos:
Pilot data: After initial setup on LX Zeus (also
pilot 2nd name in a double seater configuration)
Recording interval Other data related to flight recording with
recording (Event repetition…)
Selected task: the task will become declared
A long press on the EVENT button generates an event command that is sent to Colibri II. An event command can be sent also from the second seat.
79 | P a g e
LX Zeus v4.0.2
GPS signal priority
If there are more units (LX Eos, Colibri II and/or Flarm) connected to LX Zeus, LX Zeus will use best GPS signal reception.
Note!
In the case of LX Flarm Red Box there must be only 1 SD card inserted at once; either in LX Zeus micro SD card reader on the front of the unit or in LX Flarm Red Box unit, but not in both at once.
8 LX Zeus and Flarm
Flarm should be connected to the FLARM port on the back of the LX Zeus; Flarm will also receive power via this port. If Flarm is connected to the aircraft power network via its own power input wires, a short­circuit problem does not occur due to a built-in diode. This separates both power supplies. Up to two Flarm external displays can be connected to ports marked as Flarm external display. The SD card slot on the LX Zeus front unit is directly connected to Flarm SD interface (valid for RB), without LX Zeus interaction.
The SD card may be used for:
Flarm firmware update (Red Box or Mini Box) Downloading of flights stored on Flarm (Red Box
or Mini Box)
On the rear of the LX Zeus 5.5 and 7.0 there is enough space to install LX Flarm Red Box as an integral part of the system. All connections are plug and play. It is also possible to install any other Flarm compatible devices.
Original Flarm (Swiss) can be used as well. LX Zeus will show objects from Flarm on the display and provide power for Flarm. Task declaration with pilot information is automatically sent from LX Zeus to any Flarm with a flight recorder once the task has been declared on LX Zeus.
The SD card slot cannot be used for Original Flarm (Swiss).
80 | P a g e
LX Zeus v4.0.2
Declaration warning!
The SD card should be inserted into the SD slot without any CONFIG (.cfg) file on the card! If .cfg is on
the card, then this file will have priority and the declaration will be wrong. Thus, there would be .cfg declaration instead of LX Zeus declaration inside IGC file so it will not work!
Important!
Flight recording settings (recording interval…) will not be sent to Flarm, use SD card or Flarm Tool (see: www.lxnavigation.com – support / manuals: LX Flarm update instructions.
8.1 Flarm external displays
LX Zeus makes it possible to connect up to two Flarm external displays. Both connections are controlled from Flarm directly without any LX Zeus influence. LX Zeus system also provides 3V power for Flarm displays.
8.2 Task declaration into Flarm
In the case of an IGC approved version of Flarm, connected to Zeus Flarm port, an automatic declaration process is executed. The process is identical whether with LX Eos or Colibri II. This means that the current task and pilot data is sent to Flarm automatically.
The declaration process takes around 30 seconds. After the process is finished all LED lights on the Flarm display will switch off and the red POWER light will start blinking. This means that the process of sending task declaration to Flarm is complete.
8.3 Transferring files from Flarm
Transferring files from Flarm to a micro SD card is a very easy process. The micro SD card has to be inserted into the micro SD port, on the front of the unit (in case of LX Flarm Red Box). After the flight is completed, wait for around three minutes, then turn LX Zeus OFF and ON again. After switching on, a red POWER LED light on the Flarm display starts blinking. All other LED lights should be off. This means that all the flights that were not already on the micro SD card are now transferring to the SD card. After the red POWER LED light stops blinking the process is finished. The micro SD card, which will now contain all the flights from Flarm, can now be removed.
If the micro SD card has not been used for a while Flarm will automatically transfer all flights, that are not already on the micro SD card, from its internal memory to the micro SD card. If there are a lot of flights to transfer, the process may take up to 20 minutes! Flarm will always store a maximum 20 flights, so, if a 21st flight is recorded, then the oldest flight will be removed automatically.

8.4 LX Flarm RedBox / LX Flarm MiniBox update
LX Flarm RedBox and LX Flarm MiniBox can be updated via SD card or PC by using Flarm Tool software. Read update procedure at: www.lxnavigation.com – section SUPPORT / MANUALS: LX Flarm update instructions.
8.5 Flarm PINOUT
9 LX Zeus and Garrecht
Garrecht units can be connected to LX Zeus using supplied cables. A declaration to Flarm will be sent directly from LX Zeus.
Updating Garrecht units is not possible via LX Zeus. The connection schematic is shown below.
9.1 LX Zeus and Garrecht TRX-1090 ADSB / TRX-2000
9.2 LX ZEUS and Garrecht TRX-1500
A special cable is needed for this connection. This cable can be ordered from LX Navigation under the following code: LX-TRX1500.

LX Zeus v4.0.2
10 LX Remote Stick
LX Zeus can be controlled with a LX Remote Stick. The stick is a standard LX Navigation product, which does not differ significantly from sticks used by LX 7000/7007. Therefore, the upgrade of an existing stick is very easy. The Remote should be connected to one 485 plug and no special initialization is necessary. But note that only the short press function is supported with LX Remote Stick.

11 Second seat unit
Note!
Flarm, LX Eos, Colibri II, Voice module and Magnetic Compass should be connected to the first seat.
The second seat device is connected to the master unit via the CAN bus (it does not matter which connector on LX Zeus is used). The connection includes power and data communication for the second seat. This means that the second seat unit does not need an additional power supply. An external toggle switch makes it possible to switch off the unit during single pilot operation. Otherwise all commands are the same as for the main unit. GPS inputs on the second seat unit do not work and so DO NOT connect GPS sources to the sockets on the second seat (Colibri II, Flarm). Also, the Flarm display connectors are not used.
All LX Zeus sizes (2.8, 4.3, 5.5 and 7.0) can be used as second seat units. The first and second seat units can have different screen sizes.
LX Zeus v4.0.2
1.1 Connecting Vario Indicator
and LX Remote Stick
The vario indicator (this cannot be a USB D unit) and/or LX Remote Stick for second seat should be connected to the 485 bus of the second seat device. Both vario indicators and LX Remote Stick are compatible with existing units connected to LX 7000/7007. The Remote doesn’t require any setup.
11.2.1 Secondary Vario Indicator setup
The function of the vario indicator connected to the second seat unit should be defined under Setup > Indicators on second seat LX Zeus. Indicators (upper and lower indicator) on the second seat vario can be adjusted from the LX Zeus second seat. Automatic SC switching and external switch mode cannot be adjusted from the second seat unit.

11.3 Connecting LX Eos repeater to LX Zeus on second seat
To connect a LX Eos repeater to a LX Zeus in the second seat, simply connect units with the CAN cable, which is supplied with LX Eos repeater unit, using the CAN ports on both units.
11.4 Interaction LX Zeus – LX Zeus Second seat
LX Zeus fitted in the front seat and LX Zeus situated in second seat are two units with identical HW configuration, but the second seat unit is prepared to play a slave role in most cases. (The initialization of the second seat system is done during the production process at the factory.) The units are connected via a CAN bus using a single CAN cable. In general, the second seat unit does more or less an independent job but it receives all navigation and air data from the master. All secondary interfaces relating to the second unit, such as a LX Remote Stick, etc., should be connected to the second seat unit.
The following parameters are exchanged between both units:
11.4.1 TSK / TP / APT exchange
The TSK / TP / ATP information can be exchanged from first to second seat and vice versa. The pilot, who wants to send the task / turnpoint / airport, should press the Zoom rotary knob and then select screen button Send task / Send TP / Send APT. The other LX Zeus will receive it immediately. Also, LX Zeus will send the whole task with its statistics, moved zones, limitations etc. When a task is sent from second seat to first seat the declaration is also sent to LX Eos, Colibri II.
11.4.2 Downloading flights from Second seat
Downloading flights is possible only from the first seat unit.

PART THREE – Flying
12 Flying with LX Zeus
It is recommended that the unit is set up for every flight before take-off to ensure a stress-free and enjoyable flight. This is especially important before any contest, record attempt or badge flight.
12.1 Flight preparation on the ground
It is suggested that the following be checked:
Database status Prepare task (use new or edit options, or select imported task) Selected pilot profile with important settings
12.1.1 Before take off
Switch the unit ON at least 3 minutes before take-off (this will ensure sufficient GPS reception and
will create a base line for the baro trace)
Select correct pilot (there will be many settings specific to each pilot) Check whether the task entered is correct by using Task edit Declaration: A task selected and active before take-off will be declared automatically to connected
flight recorders (LX Eos/Era, Colibri II and/or Flarm)
Switch on second seat unit if in a double seater
90 | P a g e
LX Zeus v4.0.2
Note!
QNH setting doesn’t replace setting of elevation during booting which should be carried out every time otherwise the unit will not switch to navigation mode. QNH setting isn’t obligatory and may be omitted.
12.1.1.1 Initial setup procedure
LX Zeus requires the User to select take off elevation during the Initial Setup procedure. The
elevation set must be correct. If the take-off point is not in the database, then the elevation of the closest Airfield could be used. If the airport database is empty, or there is no closest airfield available, current elevation could be used with QNH set at 1013 hPa but if this doesn‘t match the elevation of the actual take off point then it should be changed. The User can also set QNH, select pilot (profile settings), active polar and set ballast. Settings inside Setup menu can always be changed (apart from elevation setting).
On the second seat unit, it is possible to select only the pilot doing the flying; other data can only be selected on the first (main) seat unit.
Once the elevation has been entered, LX Zeus will suggest that the current QNH value be used. If the User knows the QNH of the day it should be entered. If not, then an approximate value should be entered. QNH can be changed by pressing the VARIO button. After the input of QNH on the ground the pilot will be able to adjust altitude reading during flight if the QNH changes.

12.1.1.2 Task declaration process
The task declaration process is fully automatic and doesn’t need any pilot interaction. The planned task and pilot data is written into all connected flight recorders immediately after selection. The declaration
data will not change during flight, even if task data changes due to the select or edit process (IGC rule). The action is accompanied by a message on the display.
12.2 During flight
The LX Zeus HW and SW concept is combined in such a way that pilot input during flight is cut down to the minimum, enabling the pilot to give full attention to piloting. It is important to point out that there are many shortcuts which enable direct and fast access to most important functions. If confused, just wait for around 15 seconds and the Auto close feature should close the current dialog. A clear indication that the unit is in flying mode can be determined by checking that the Logbook page is replaced by the Statistics page when the STAT button is pressed.

Note!
When the task has not been started yet, the statistics data is limited to take-off and flight duration.
12.2.1 Set MacCready (MC), Ballast, Bugs and QNH
Note!
If the task consists of more than three legs, use zoom to select legs of interest.
Note!
QNH setting doesn’t replace setting of elevation during booting; this should be
carried out every time otherwise the unit will not switch to navigation mode. QNH setting isn’t obligatory and may be omitted.
After a short press on the VARIO button a new window will appear – MacCready. The menu will give options, to adjust MacCready (MC), Ballast, Bugs and QNH. Setting MacCready, Ballast and Bugs will influence the glider polar and MC speed, sink speed, cruise speed, as well as the overall efficiency that will also be changed.
Entering a Bugs setting will decrease the efficiency, which will affect the final glide calculation.
Example:
Efficiency is 30. Bugs setting is 10%.
Equation: Fbugs = f x (1-bugs [fraction])
= 30 x (1-0.10) =
LX Zeus v4.0.2
= 30 x 0.9 = 27
QNH setting:
The pilot should input the actual QNH value of the airport being used for take-off during the initial setup process. This action should be carried out on the ground; after take off the menu will not open any more. After input of QNH on the ground the pilot will be able to adjust the altitude reading during flight, if the QNH changes.
12.2.2 Statistics
The statistics page will open after a press on the STAT button.
The statistics page offers the following statistics data:
Thermal analysis: Two types. OLC: Calculation of OLC distance, score etc. Baro: Shows baro trace from take off until present position Task: Presents task statistics data divided by legs Route: Shows task and flown distance Timer: Starts timer
The statistics page colour structure can be adapted to suit a pilot`s personal requirements. This can be done under: Setup > User Interface > Statistics colours.

LX Zeus v4.0.2
End Flight function will close the flight so don’t use it during flight. Once End Flight has been commanded the flight will end and the flight recorder (LX Eos/Era and Colibri II) will be forced to stop flight recording and create an IGC file.
12.2.2.1 Thermal Analysis
There are two pages of thermal statistics, which are selectable by pressing the screen buttons:
Thermals 1 Thermals 2
Thermals 1
Every column depicts a thermal. The column is sliced into various colours and widths. The colours are blue, yellow and red. These colours depend on the current MacCready setting. If the thermal strength is below the MC setting, then the column is blue, if it is above then the colour is red. The yellow colour is around the MC setting (plus / minus 20% of MC).
Thermals 2
This page shows all thermals of the flight; as a reference the actual MC setting is shown also. The value depicted corresponds to average thermal vario of an individual climb from entering to leaving the thermal. The thermal is only shown after a gain at least 100 m of altitude. The dotted red line through the columns shows the MC setting. This assists in determining a good MC setting.

Note!
Use Zoom rotary knob to scroll through the legs, as the display is capable of showing only 4 legs at once.
12.2.2.2 OLC Calculation
OLC calculation is a calculation of OLC points according to OLC rules. The current rules can be checked at:
http://www.onlinecontest.org/olc-2.0/gliding/cms.html?url=rules.
In general, the scoring software selects a departure point within the unpowered part of the flight with up to 5 waypoints (turn-points) and a finish point in such a way that the following two conditions are fulfilled:
The raw point score (1 point per km) from the departure
point via all waypoints to the finish point is a maximum.
The departure altitude is not more than 1000 m higher than
the finish altitude.
To stimulate “area“ flying a FAI bonus is granted. For this purpose, the scoring program checks whether FAI triangles can be fitted into the flight route and, if so, determines the largest such triangle for calculating the FAI bonus.
There are three NavBoxes showing how many OLC kilometres have been achieved so far. One is labelled OLC and shows the kilometres made to current point in the flight. The other one is labelled OLC HOME and shows how many kilometres will be made if a return to the take-off point is achieved. The third NavBox is OLC speed, which indicates the speed over the whole OLC distance flown.
12.2.2.3 Baro trace graph
A baro trace from take-off to the current position will be opened by pressing the button next to Baro. Customisation of colours is possible at SETUP/USER INTERFACE/ STATISCTICS COLOURS.
12.2.2.4 Task Statistics
This page will open after pressing Task screen button. Task statistics are shown for the whole task and for individual legs.
Speed: Average speed Dist: Flown distance Dur: Duration V Avg: Average value of vario in thermals (circling) Circ: Percentage of time circling (not flying straight)
Statistics are also available on 1st subpage on Task (TSK) navigation page.

12.2.2.5 Route
Route option is a feature showing the track already flown and the current task on the map. This enables the pilot to see how precise the flying was and where detours were made.
12.2.2.6 Timer
To use a stopwatch, the timer function can be used which is located in Statistics. Timer manipulation is as follows:
Select Start timer screen button and timer will start. Stop timer by pressing Stop timer screen button. Reset timer.
12.2.3 Follow me
The Follow me function can be accessed by long pressing the Vario/Flarm button (the Flarm menu), selecting the Flarm object we want to follow using the zoom rotary knob and pressing the TSK/Move button, which selects the highlighted Flarm object.
12.2.4 Special functions
12.2.4.1 Event function
This function is active only if LX Eos and/or Colibri II is a part of the system. A long press on the EVENT button will send a command to connected flight recorders to activate the event function. This means recording in shorter intervals as a default for a limited time (default: event fix interval: 1s; event repetitions: 20). Event settings are under Setup > Logger.

12.2.4.2 Marker setting
NOTE:
Marker function is possible only in TP navigation
If the pilot wants to mark a position of interest, for example a suitable out-landing place, thermal hot spot…), this can be done by activating the Marker function. The process is very simple and doesn’t require much attention by the pilot.
To mark a position the pilot should do as follows:
On TP navigation page, press Zoom rotary knob Select screen button Add marker
The marker is shown as a yellow triangle on the map. Only one marker can be active at any one time. To set a new one simply repeat the procedure.
The marker is stored as user turn-point designated as #MARKER. If edit TP function is used the #MARKER can be converted into a normal TP. #MARKER can also be deleted after using the Delete TP command. To navigate to #MARKER point, simply select #MARKER under Select TP dialog.

12.2.4.3 Pan mode
Note!
ARM command can be executed at any
time, even on the ground.
It is possible to move the position on the map using the Volume and Zoom rotary knobs. Pan mode is available on all three navigation pages (TP/APT/TSK). During the flight, the tail and Flarm objects are displayed on the map in pan mode.
To activate the mode, press button SELECT and choose Pan mode screen button. It will then be possible to move to the desired location on the map and, if GO TO is used, the system will start navigation to a selected position on the TP navigation page. The name of this selected point is displayed as the current time.
A task in Pan mode can be created by accessing Pan mode from the TSK navigation page. For more information see chapter Creating a task in Pan mode.
LX Zeus v4.0.2
12.2.5 Task Start
Task start is quite a complex procedure, especially with a high density of gliders where many of them intend to start at nearly the same time. When the pilot intends to cross the start line, a simple operation should be carried out:
Press on TSK button and press ARM screen button.
A message ARMED will appear on the display. The word Armed will remain until the first line crossing. After crossing the line the task will start automatically without any further pilot interaction.
If the start line is crossed multiple times, the time of the last valid start will be used for statistics calculation. Every next start is also displayed by a green message Task started at...
Under Settings > User interface > Track/destination settings the pilot can choose whether navigation is aimed at the zone center or the zone closest point.
Disarm function will disable the Arm command.
98 | P a g e
Note!
After Restart, the unit will change immediately into
ARM status, which means ready for next start.
Note!
In the event that the pilot crossed the start line and forgot to execute ARM before that, execution of NEXT TP function will solve the problem. Navigation to the first turn point will then be offered and the statistics page will become available. LX Zeus will find last valid start line- cross and use it for statistics.
12.2.5.1 Start Conditions / Limitations
Some competition rules prescribe limitations (restrictions), which should be respected before the start and also while crossing the start line. After a short press on TSK/MOVE screen button, Limitations will appear. Select Limitations screen button to enter limitation setup menu. Limitations are divided to:
Gate time Before start Start conditions
LX Zeus v4.0.2
Gate time sets the time when the start line will be opened. Calculated time will be time set on LX Zeus (UTC or UTC offset time). LX Zeus time is by default set to UTC time. Time offset can be changed under Setup > Locale > UTC offset.
Below start altitude and time can be set. The glider should be below the selected altitude when starting.
Start conditions can be limited to start altitude and ground speed.
A limitation indicator will appear on the screen (only on TSK screen). First the pilot needs to add the Limitations indicator to the screen by modifying the TSK layout. Go to Setup > Layout and edit TSK navigation page.
12.2.5.2 Task Restart
If the pilot decides to restart the task, having already started, it is possible to do this by executing the Restart function. It is accessed by pressing TSK/MOVE button and then pressing the Restart screen button. After pressing Restart, the task will be reset (doesn’t matter on which leg) and a new start can be performed. Also, the task statistics will be reset.
