LX Navigation Eos Variometer Second Seat Repeater
General Description
The LX Eos 57 Second Seat Repeater is a second seat repeater connected via CAN BUS.
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's 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 their equipment can be found in almost any gliding club!
LX Navigation equipment has always been ground–breaking.
LX Navigation motto?
Be the first. Be the best. Be different.
Why Eos?
Because the Eos is a junction of old–school analogue style and full function possibilities of the large transflective LCD screen.
A state–of–the–art vario unit, leading the way for technology innovation in the field of sensorics, gathering information, processing and helping the pilot with clear, clean and intuitive interface.
We keep the most important function of the vario – showing lift and sink – on an analogue, high contrast needle and still manage to spoil you with all the information a pilot could require for his everyday crosscountry, competition or club flight.

Configuration
LX Eos can be used in two different configurations:
• A standalone: LX Eos represents vario navigation system and has all options active. Unit will turn on when enter switch is pressed.
• LX Zeus configuration: LX Eos serves as vario system controlled from LX Zeus. Unit will turn on automatically when main switch is turned on. All setup settings are set on LX Zeus. Flarm radar settings and thermal assistant settings must still be set on LX Eos. Some of options are disabled (setup, task edit) but all of LX Eos options will become active when backup mode is detected.
Technical Data
A large 2.7″ transflective LCD display shows all flight–relevant information to the pilot. The Eos 80 boasts an analogue needle, which clearly shows current lift, SpeedToFly or other flight parameter. A single push/rotary knob is used for all pilot to Eos communication (Eos 80).

• Bluetooth indicator – appears only when a Bluetooth device is connected to the Flarm port and communicating with the Eos.
• Wi–Fi indicator – appears only when a Wi–Fi device is connected to the Flarm port and communicating with the Eos.
• GPS indicator – is always displayed, a green arrow indicates good GPS signal, and a red one indicates bad GPS signal.
• Circling/SC mode indicator – indicates whether Eos is in Speed Command (SC) or Vario mode.
• Battery status indicator – shows the current state of the airplane’s battery. White battery outline indicates it is using the airplane’s battery. A red battery outline indicates it is using its built–in battery.
Use of rotary switches
To exit edit mode, fill out all of the fields (when a number is in question) or simply choose the enter sign (⏎). For quick change (multiplication by 10 steps) press enter button and while being pressed, rotate rotary switch.
To exit from any subpage or list, a pilot has 2 options:
• Select “Exit” option which is always located at the end of each page / list
• Move to the top of each page / list where a blue circle with white a backward arrow is located (←).
Exit option is activated, when this circle becomes filed with blue.
Flying With Eos
To get the best out of the LX Eos, 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.
Flight preparation on ground
• Check if you have desired TP, APT and Airspace database uploaded.
• Prepare a task.
• Check pilot information (this information is written into the flight declaration).
• Check logger settings.
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 of the baro trace).
• Select correct pilot (many settings belongs to pilot) on initial setup or create new.
• Check task if it is correct after using of Task setup.
• The actual task during take–off will be declared in flight recorder automatically.
During flight
The LX Eos HW and SW concept is so far optimized that the pilot doesn’t spend too much time to operate the unit during flight. A very significant indication that shows that the unit has changed to flying mode is Logbook replacement with statistics page.
Set QNH
The pilot should input actual QNH value of the airport where he will take–off. This action should be carried out on ground, after take–off, change of QNH in Setup/QNH Res menu will adjust altitude reading to actual QNH setting.
Wind calculation
LX Eos is able to measure wind under two different methods. Wind calculation results are shown on main vario page and on thermal assistant page. LX Eos will switch between straight and circling method automatically and history of wind will be counted in new measurements.
• Circling:
Calculation is based on ground speed (GS) oscillation due to wind influence in circling. The method is active exclusively during climbing process. The process start automatically after circling is detected. The method is based on fact that the ground speed is affected by wind. GS is maximal by tailwind and minimal by head wind. This phenomenon is used by GS difference calculation method.
• Straight flight:
On straight flight, wind will be calculated with use of iterative method which is based on IAS, GS and TRK measurements. 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 remaining distance over all TP until finish (not over already flown turn points). Wind influence for individual legs is based on current wind data.
Event function
User has option to set one of the user inputs to Event. If event switch is pressed during flight, it will enable faster record interval in flight recorder (recording in shorter intervals as default for a limited time). Event parameters can be set in Setup/Logger on LX Eos unit. The action is accompanied with a clear message.
Task start
It is started automatically when glider leaves start TP observation zone. Navigation to next point will start. If pilot wishes to navigate back to starting point, he must simply use “Goto” option in task setup menu. Please refer to Task page chapter.
No task statistic is available on LX Eos.
After landing
It is recommended to keep the instrument ON for a few minutes after landing. This will ensure base line of baro trace.
10s after landing is detected, statistic page will be shown automatically where 10min countdown can be seen.
Pilot can wait for 10min of press enter to end flight. Calculating security message will follow and then logbook will be offered to the pilot. At this point unit can be switched OFF or flight download process can start.
Downloading flights
Insert micro SD card to external micro SD card holder. Select logbook page and search for a flight that you wish to download. Press enter on that flight and select Copy option. Progress window will inform pilot when flight is copied to external SD card. File format of flight is .IGC.
Installation Options
LX Eos is compatible with all LX CAN based devices (LX Zeus, LX Joy, LX Eos Repeater, CAN Compass, AHRS, and others). LX Eos has an integrated CAN terminator so other terminator should not be used. Only one CAN terminator should be used (be careful when using LX Eos with LX Zeus).
Configurations
• LX Eos – Flarm – OUDIE
• Lx Eos – OUDIE
• LX Eos – Flarm – OUDIE – 2nd Seat – 2nd OUDIE
Navigation Page
In order to use this page to its maximum extent, the user should first import turnpoint, and airfield files. For more information on this subject, please refer to Setup/SD Card/Load TP. If LX Eos 80 is used in LX Zeus configuration, TP database selected under TP/Task/Eos list on LX Zeus is automatically transferred (unlimited number of TP’s). TP is displayed as a white dot with a ”W“ written inside (Waypoint). Navigation is always ”track up“.
On the top of this page the name of the selected turnpoint is written. On the right side of the screen, next to the IAS bar, Final glide (FG), Bearing (BG), Track (TRK) and Distance (DIST) to the selected point are written.
Below the plane icon, a steering symbol will inform the pilot for how many degrees (°) does he need to correct his track in order to fly towards the selected turnpoint.
In the left part of the screen, standard wind information can be read. The Arrow shows the winds course in regards to the glider, the degrees it’s direction from the North and the speed is shown below.
Pressing the enter button whilst on TP page will open a TP settings menu. This menu can be used for setting the Zoom level, as well as selecting the desired point.
The desired point can be chosen either by scrolling to it, or by using a filter. Three different filters are available for narrowing down your search: Name, Code and Distance. After confirming the desired filter, a filtered list will appear.
These options are valid only when used without a Zeus. Otherwise, Zeus’ turnpoint selection shall be used. Selected point is saved after power reset.
