1 Introduction
The LX Eos is “all-in one” standalone speed to fly variometer, flight recorder, final glide calculator and simple
navigation system with internal backup battery, audio warnings, vario beeps and voice messages. The unit
has User and Flarm input/output to connect PDA/PNA and Flarm units to the system. It is the smallest vario
system with outline dimensions of 60mm x 60mm with standard 57mm cut-out. It will fit into every glider
panel. It is able to supply PDA/PNA units with 5 V/500 mA and 3.3 V/100 mA output on User output
connector. LX Eos has built in high precision digital sensors based on latest MEMS technology for altitude,
vario, speed and G-force. All sensors are sampled with more than 100Hz sample rate. All real time data is
shown on its indicator. Vario data is shown with mechanical needle via stepper motor. As integral part it has
1.8” sunshine readable LCD display to show all user defined data during flight. For accessing all system
options, a rotary switch with a push button is used.
A double seater installation is possible by adding LX Eos Repeater on system CAN bus.
An integral IGC approved flight recorder with ENL level detector will record flight to internal solid state
memory (8GB). All flight can be copied to external SD card after flight.

Later in manual “backup mode” will be written from time to time. Backup mode is when LX Eos is used in LX
Zeus system and while flying, system loses main power. LX Zeus will turn off, but LX Eos will use internal
backup battery to continue working. All functions of LX Eos are operational in backup mode so pilot can
safely navigate back to home or complete the task.
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 systemcontrolled 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.
Unit has capability to be updated to any later FW release.
As standalone system, please refer to Setup/SD Card/Update, how to update the system.
As LX Zeus configuration, LX Zeus will automatically update LX Eos if required to latest version, so no extra
action is required.
