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'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 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 Era?
Because Era is the latest breakthrough in the world of electronic variometers. The 3.5’’ large transflective
LCD display will show you the way when flying tasks, cross-country flights, or just plain airfield soaring.
With the Wi-Fi/Bluetooth module inside, you are stepping into the age of connectivity. The Era of
connectivity, if you will.
Always know your position and heading, with clearly visible lift or sink, thanks to our gradient digital needle.
The ERA 80 is a miniature package that includes everything a glider pilot needs, from navigation, to statistics,
AHRS, G-meter, up to the very root of this device –the vario function. All this comes with a backup battery
and IGC certified logger. What more do you need?
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 (Era, 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 flight
parameters such as final glide information, Speed Command (SC) as well as basic navigation. Our varios also
have an internal battery which means that your IGC logs do not depend on your glider`s batteries.
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 Introduction
The LX Era is an “all-in one” standalone speed-to-fly variometer, flight recorder, final glide calculator and
navigation system with an internal backup battery, audio warnings, vario beeps and voice messages.
The unit is capable of providing APT (airport), TP (turnpoint) and TSK (task) navigation on three dedicated
navigational pages. Navigation pages feature Navboxes showing bearing to point, track, distance and final
glide with airspace shown graphically, airports and turnpoints.
The vario is designed to fit a standard 80mm aviation cut-out hole. 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 Era has built-in high precision digital sensors based on latest MEMS technology for altitude, vario, speed,
3-axis gyro and 3-axis accelerometer sensors. A minimum sampling rate of 100 Hz is applied to all sensors.
The digital needle can be assigned to show one of multiple parameters (vario, netto, g-force, speed command
etc.). By default, it is shows vario value.
As an integral part, it has a 3.5” sunshine readable transflective LCD display to show all user defined data
during flight. For accessing all system options, two rotary/push knobs are used. A voice module is also built in
for audio warnings.
A double seater installation is possible by installing an LX Era Repeater and connecting it to the system via a
CAN bus.
An integral IGC approved flight recorder with ENL level detector will record flight to internal solid-state
memory (8GB). All flights can be copied to an external SD card after flight.
For backup and safety reasons, it has an internal battery which will provide power to the Era for three to five
hours after the main power supply is disconnected. The integral charger will charge the backup battery when
external power supply is connected (12V).
LX Era features are:
- 3.5˝ transflective technology sunlight readable display
- Integrated G-meter (g-forces recorder)
- 3-axis gyroscope
- 3-axis accelerometers
- 50ch GPS receiver as an integral part of the system
- Completely new design using latest pressure transducers technology
- Extremely fast vario data acquisition
- Rotary knob with push function, for simple and effective handling
- Nearly unlimited memory space for flight recorder
- ENL (Environment Noise Level) sensor
- 5 user defined status inputs (SC, VP, gear, brakes and ballast)

The term "back-up mode" will be used in this manual to define the situation where main power is lost in
flight and the LX Era is used as part of the LX Zeus system. The LX Zeus will turn off, and the LX Era will use
its internal backup battery to continue working. All functions of the LX Era are operational in backup mode
so the pilot can safely navigate back to home or complete the task.
LX Era can be used in two different configurations:
- As a standalone: LX Era provides a vario navigation system and has all its options active. The unit
will turn on when the enter push/rotary knob is pressed.
- LX Zeus configuration: LX Era serves as the vario system controlled from LX Zeus. The unit will turn
on automatically when the main switch (Zeus) is turned on. Flarm radar settings and thermal
assistant settings are set on LX Era while all other settings are controlled by settings on the LX Zeus.
Some options are disabled on the LX Era (setup, task edit) but all options become active when
backup mode is detected.
Unit has the capability to be updated to any later FW release free of charge. (see: www.lxnavigation.si)
When used as a standalone system please refer to Setup/Transfer/Update to learn how to update the
system.
When used as part of a LX Zeus configuration, the LX Zeus will automatically update LX Era if required to
latest version, so no extra action is required.

1.3 Operation
Switching the unit on
There are two different ways of turning the unit on.
Standalone units are turned on by pressing the lower push/rotary knob until the LX logo appears.
Varios used alongside a Zeus are turned on automatically when the main unit (the Zeus) is turned on.
The device name with serial number and software version information will follow after the logo appears. After
the boot procedure, the initial setup with pilot selection and elevation/QNH setup will be shown. If the device
is used with the LX Zeus, the initial setup screen does not appear, since the initial setup is done on the LX Zeus
unit.
Switching the unit off
When on the ground (in this situation the flight recorder will not be running), disconnecting the main power
supply will turn it off. LX Era will start to count down 3 seconds before it turns itself off. You can also turn the
unit off by going to the Setup page and scrolling down to Shut down. After selecting the shutdown option, you
will be asked to confirm. After the confirmation, the unit will perform a 3 second countdown and then turn
off.
In flight mode (in this situation the LX Era detects IAS and the flight recorder will be running) it will not switch
off until the flight has ended, unless the Shutdown option in Setup menu is used. Otherwise, the flight will end
automatically 10 min after landing or if manually selected by the user.
To manually end the flight, refer to the instructions found in the statistics page section.

2.4 External switch installation
Up to five external switches can be connected to LX Era. To
connect an external switch to LX Era you have to use the
external switch interface board (included in package).
Every slot available has a signal input and ground input.
The configuration of inputs can be set under Setup ->
Inputs.
User can use two different connection styles:
- 2 wire connection: Connect switch signal and ground
wires to interface board.
- 1 wire connection: Connect switch ground wire to glider
common ground and connect switch signal wire to
interface.
Be careful not to connect signal wire to common ground
input (see picture showing common ground inputs)
The common ground is connected to the glider common
ground via power supply cable (GND).
All inputs except SC will be “active” when the switch is closed (i.e.: signal and ground are in short circuit). If
“Inv” (Invert) is checked on input setting then “active” means when the switch is open.
Example: airbrake warning will be active when switch is not closed and Era is in flight mode. Warning will
disappear when switch is closed.
SC input has its own setting under Vario/SC menu and can be set to be active on when selected to “on”,
“off” or “toggle”.
Example of both connections (1 and 2 wire)

Use of rotary switches
To move around and access all functions of the unit, two rotary knobs with push buttons are used.
The upper push/rotary knob serves the function of Cancel and from now on will be referred to as ‘’Cancel’’.
Pressing the upper push/rotary knob will exit from a menu and cancel the settings. Turning the rotary knob
in most pages will change the volume.
In situations when you are choosing a value (e.g. QNH and altitude in the initial setup) it will change the
value by 10-fold.
The lower push/rotary knob serves the function of Enter and from now on will be referred to as ‘’Enter’’.
Pressing the lower push/rotary knob will enter a menu, or enter a value, or open a hidden menu.
Turning the rotary knob will swipe through pages, menus, or change values by 1, depending on the situation.
To change the value of a parameter, enter must be pressed to activate the rotary keyboard (appears on the
left).
Use the lower rotary knob to input the desired value and confirm it by pressing enter.
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 holding it pressed, rotate the
rotary switch.
The upper push knob is used for zooming in on all navigation pages. When choosing a value, it will behave
the same as the upper push/rotary knob –it will increase the value by 10-fold.
The lower push knob is used for zooming out on all navigation pages. When choosing a value, it will behave
the same as the upper push/rotary knob –it will decrease the value by 10-fold.
A red cross across a page is a standard aviation notification, which indicates
that this page is either not available or not working for some reason. On
navigational pages, it is usually due to bad GPS connection and on AHRS page,
it is indicating that you do not have an AHRS unit connected to your Era.
Connecting the missing module or antenna, or allowing the antenna to get a
GPS connection will eliminate this symbol. Pages that are not used can be
hided, as explained in section 4.11.12.
