3Basics
3.1 LXNAV S80 at a Glance
LXNAV S80 is standalone digital vario meter final glide calculator and navigation system with
simple moving map. The LXNAV S80 has both GPS/Flarm and PDA/PNA inputs/outputs. The
unit has standard dimensions that will fit into a glider panel with an opening of - 80 mm
diameter (3.15”). It is also able to supply PDA/PNA with power (5VDC/1A). The unit has an
integrated high precision digital pressure sensor and inertial system. The sensors are
sampled more than 100 times per second. Real time Data is indicated with the vario needle
airspace map and up to 4 variable number fields displayed on QVGA 320x240 pixel 3.5 inch
high brightness (1200 nits) colour display. To adjust values and settings the LXNAV S80 has
two rotary push button knobs and three additional push buttons.
The LXNAV S80 can be expanded with one or more repeaters (LXNAV S80D) through the
CAN bus.. This allows both pilots in a two seat glider to have equal control of all functions
from the front or the rear seat.
3.1.1 LXNAV S80 Features
•Extremely bright 3.5’’ 8.9cm QVGA colour display readable in all sunlight conditions
with the ability to adjust the backlight .
•Two rotary switches (knobs) with push button function and three push buttons are
used for input.
•Pre-loaded polar database for almost all gliders.
•GPS/Flarm and PDA/PNA inputs/outputs
•Flarm Indication if Flarm is connected to the GPS/Flarm port
•Needle indicating various data such as netto vertical speed relative (super netto) and
vertical speed (vario).
•320x240 pixels colour screen for additional information such as average thermal
vario time speed etc…
•Many custom audio settings

S80 Version 4.92 November 2014

4System Description
4.1.1 Push Button
The two Rotary switches have a push button function. LXNAV S80 can detect short or long
press of the push button. A short press means just a click a long press means pushing the
button for more than one second.
4.1.1.1 Power Button
The system is powered up using any of the push buttons or a short press of any of the
rotary knobs. A long press of the upper rotary knob system will turn the S80 off.
4.2 Rotary Switches
The upper rotary knob is designed for direct volume control. Pushing the upper rotary knob
the user can set the volume for the Vario Speech and Flarm beep. The system can be shut
down using a long press of the upper rotary knob.
The Lower rotary knob is used for MC and other settings. With the lower rotary pushbutton
we can toggle between MC Bal and Bugs settings. In all other menus this knob is used for
setting values and editing texts…

4.4 User Input
The LXNAV S80 user interface consists of dialogues which have different input controls.
They are designed to make the input of names parameters etc. as easy as possible. Input
controls can be summarised as:
•Text editor
•Spin controls (Selection control)
•Checkboxes
•Slider control
To move the function from one control to another rotate the lower rotary knob as follows:
•Clockwise rotation will select the next control.
•Counter clockwise rotation will select the previous control. PUSH button enters the
selected feature.
•Faster rotation of the rotary knob will increase the rate at which the value changes. i.e.
bigger steps in value.
4.4.1 Text Edit Control
The Text Editor is used to input an alphanumeric string; the picture below shows typical
options when editing text/numbers. Use the bottom rotary knob to change the value at the
current cursor position.
Turn the bottom rotary Knob to set the character and then press the enter key to move to
the next charachter to the right. Press the escape key to move back to the left. When you
have finished editing press the Enter key. Pressing the bottom rotary knob will enter or exit
a controll.
4.4.2 “Spin” Control
“Spin” controls are designed for numeric parameters. Rotate the knob to increase/decrease
the selected value. To increase the values in larger steps spin the bottom rotary knob
control faster!

S80 Version 4.92 November 2014
Page 12 of 61
4.4.3 Selection Control
Selection boxes also known as combo boxes are used to select a value from a list of
predefined values. Use the bottom rotary knob to scroll through the list.
4.4.4 Checkbox and Checkbox List
A checkbox enables or disables a particular parameter. Press the bottom rotary knob to
toggle the value. If an option is enabled a check mark will be shown otherwise an empty
rectangle will be displayed.

S80 Version 4.92 November 2014
Page 13 of 61
4.4.5 Slider selector
Some values like volume and brightness are displayed as a slider
With a push of the rotary button you can activate the slide control then with rotation of the
knob you can select the preferred value and confirm it with the push button.
4.5 Switching off
Switching the unit off is archived by selecting the shutdown option within the Setup menu.
By using this method of shut down all your settings are saved.
All settings are saved during the power off procedure. We strongly recommend
switching off the unit using the shutdown option in the settings menu.
If the system is powered off by the master switch changed data will not be
saved. Flight parameters at takeoff such as target altitude and position will
remain in the stored memory so your final glide calculations are not affected.

S80 Version 4.92 November 2014
Page 17 of 61
The central number and chevrons indicate if the Flarm target is bellow or above and
by how many meters/feet. The number in the bottom left indicates the range in
meters/feet.
5.3 Waypoint Screen
The Wpt screen is a quick access screen to provide simple navigation to a Waypoint or
Airport. By rotating the bottom rotary knob you can change the range of the display
from 1KM to 100Km
The first page shows a line to a selected waypoint the name of the selected waypoint
at the top of the screen and the relative bearing and chevrons indicating the direction
to turn towards the selected waypoint. (The Navboxes can be configured with distance
and arrival Altitude.)
5.3.1 Quick access menu

software the range can be set to m/s kts km/h mph or fpm (in Setup Units
Vertical speed)
Upper numbers display Vario Netto Average Vario
Lower number display True Airspeed and 60 minute task speed
Speed to fly bar symbol is indicating which speed you have to fly relative to the
current MacCready setting sink rate and speed. One arrow means 10units of speed
faster or slower. Up red arrows mean fly slower and down blue arrows mean fly
faster.
Red diamond symbol can show netto or average vertical speed or g-force.
Blue arrow symbol shows current MacCready value.
Green T symbol represents last thermal average value.
Yellow Bar can show Max and Min values or G meter
