3 Basics

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

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!

This setting is the altitude reserve or safety altitude and is the height that the instrument
adds to the final glide altitude required so the glider arrives over the final glide destination at
the selected safety altitude. Once the safety altitude has been specified, the pilot has to
keep the final glide indicator on 0 to arrive at the safety altitude.

with step 1.0 s or 0.1 s. Default value is 1.5 s.

5.5.2.2 Vario sound filter

Sets a time constant of vario sound. The value can be adjusted between 0.1 and 5 s with
step 1.0 s or 0.1 s. Default value is 1.5 s.

5.5.2.3 Netto filter

Sets a time constant of the Vario Netto needle. The value can be adjusted between 0.1
and 5 s with step 1.0 s or 0.1 s. Default value is 1.5 s.

5.5.2.4 Relative filter

Sets a time constant of the Vario Relative needle. The value can be adjusted between 0.1
and 5 s with step 1.0 s or 0.1 s. Default value is 1.5 s.

5.5.2.5 SC filter

Sets a time constant of the SpeedToFly needle. The value can be adjusted between 0.1
and 5 s with step 1.0 s or 0.1 s. Default value is 1.5 s.

5.5.2.6 Smart Filter

The Smart Filter allows additional filtering of the vertical speed. It defines the difference
between increasing vertical speed versus decreasing vertical speed. (E.g. If the vario filter is
set to 1s and the Smart Filter set to 4s, the filtering for increasing vario would be 1s and for
decreasing vario would be 2s. This will produce an effect similar to a Sage Variometer.)

Sets full scale range of the vario (2.5 m/s, 5 m/s or 10 m/s). Default value is 5 m/s (10 kts).

5.5.2.8 Dead Band (SC tab)

Defines the width of the audio dead band in speed to fly mode. Default value is ±1 m/s.

5.5.2.9 Auto SC

Defines the conditions when the instrument will switch automatically between vario and
speed to fly mode.

• OFF: Switching is exclusively by an external switch connected to the S80.

• GPS: When the GPS detects that the glider is circling an automatic change over to vario

will happen after approximately 10 seconds. Detection of straight flight will cause a
changeover to speed command.

• TAS: When the TAS exceeds a pre-set value. The TAS at which switching occurs can be
selected in 5 km/h steps from 100 up to 160 km/h (or the equivalent in knots or mph).

• G-meter – for switching between cruise and climb mode based on the G measured by
the inertial system. When glider will start circling, S80 will automatically switch from
cruise to climb mode.

The external switch wired to the LXNAV S80 has absolute priority and will override
all other switching methods.

Vario Setup

S80 Version 4.92 November 2014

Page 38 of 61

5.5.9.1 TE compensation

The LXNAV S80 offers two methods of vario Electronic Total Energy Compensation:

• TE Pitot tube

• Electronic TE compensation

It is important to note that the method of TE compensation is set up when the
instrument is installed by virtue of the pneumatic connections made to the TE and
static ports. Changing the compensation type in the setup screen below WILL
NOT change the method of compensation - the pneumatic plumbing has to be
changed first.

If the TE pitot tube has been connected TE compensation should be set to 0%.
There is no further adjustment of TE compensation possible. Quality of the TE
tube is the one and only factor.

If the electronic TE option has been installed TE compensation should be set to
100%.

The electronic TE compensation can be fine-tuned during flight using the following
procedure: it is essential that this is only done in smooth air; it is not possible to tune the
TE accurately in turbulent air.
Set TE compensation to 100%. 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 the vario will indicate about –2 m/s
(-4 kts). 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 the
compensation is too low; increase the TE%; and vice versa. Try another “zoom” to assess
the change and make further adjustments if necessary.

Electronic TE compensation is only effective when the Pitot tube and static sources are co­located and the pneumatic lines to the instrument are approximately the same length. The
best sensor to use is the combined pitot/static Prandtl tube. If problems are experienced
with the electronic TE compensation the most likely cause is the glider's static source. The
static source can be checked by plumbing the pneumatic tubes for electronic compensation

S80 Version 4.92 November 2014

Page 39 of 61

and then setting the TE: to 0%. In still air accelerate to approximately 160 km/h and slowly
reduce the speed. Observe the vario indicator. If the static source is good the vario should
immediately start to move to show a climb. If the needle firstly 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 fin­mounted pitot/static source such as a Prandtl tube might help.

5.5.9.2 SC switch

The LXNAV S80 has an input for an external speed command switch. Using the external
switch it is possible to switch between SC and Vario manually. Setting the SC switch to ON
means that closing the switch will cause the instrument to enter SC mode and setting SC
switch to OFF means that closing the switch will select Vario mode. There is a third option
by setting SC INPUT to TASTER and connecting a push button to the input; each key press
will toggle between SC and Vario (mandatory setting for LX Remote).

There is another input called VARIO PRIORITY. When this input is activated by
grounding the appropriate wire the unit will change over to Vario immediately.
This input wire is set open (not grounded) as a factory default on delivery.

5.5.9.3 Digital Input 1 and 2

The LXNAV S80 has two external digital inputs which can be set to indicate gear,
airbrakes and water open or closed.

Input pins are available on rear DB15 connector, but they are not wired.

5.5.10 Indicator setup

Vario Needle: Can be set to Relative, Netto, Speed to Fly or Vario
SC needle: Can be set to Relative, Netto, Speed to Fly or Vario

5.5.11 Comms. Setup

Used to configure the two ports on the back of the S80 for connection to a GPS/Flarm
source and to a PDA

Each port can be configured separately. If your PDA device does not support automatic
switch to DIRECT LINK between GPS and PDA port, here is manual GPS-PDA link menu.
When autobaudrate is enabled, the LXNAV S80 will automatically search on all speeds to
receive valid data. When the S80 receives a valid NMEA sentence it will lock on that baudrate
and stop searching. In case that communication is lost LXNAV S80 will start again searching
on all baudrates.

Baudrate on PDA must not be lower than the setting on GPS port

To get better performance of LXNAV S80 it is recommended that both baudrates
be set as high as possible.

NMEA output on PDA port can be enabled or disabled. If you are not using a PDA port, this
setting should be disabled.

Bluetooth is not supported in this version

5.5.12 Battery Chemistry Setup

A new feature within the S80 is the ability to configure your battery chemistry and
battery warnings. Batteries used in gliders today are not just the old style lead acid
battery but also Lithium Iron and Lithium Iron Phosphate. Each battery type has a
different power delivery curve and it is now possible to configure the Low and High
Battery warnings

S80 Version 4.92 November 2014

Page 41 of 61

Select Battery from List gives you a drop down list with the suggested battery settings
for Full Voltage, Low Battery Voltage and Empty Voltage as pre-sets. Selecting one of
these will set the values in the following boxes.

Alternatively you can manually change the Full Voltage, Low Battery Voltage and
Empty Voltage if your battery type is not listed.

5.5.13 Files

5.5.14 Polar and Glider

The Polar and Glider section allows you to load and edit a set of parameters for your
gliders Polar. You can select from a pre-defined list of nearly every common Glider or
make your own Polar.

Select Glider from List: Presents you with an alphabetical list of all the common gliders
and associated Polar data. All glider data will be copied from the chosen polar. Then check
the best glide ratio and minimum sink rate, to see if the polar data matches the glider
performance, you may look in MacCready setting menu.

S80 Version 4.92 November 2014

Page 45 of 61

You can modify the polar by changing coefficients a, b and c. A polar is defined as a
quadratic equation with the parameters a, b, and c. Use the SeeYou program (Tools->Polar)
to calculate coefficients a, b and c for a given glider’s polar. The program requires three sink
points entered at selected speeds (e.g.: 100 km/h, 130 km/h, and 150 km/h). The program
will calculate the values of a, b and c, which should be noted and entered into the LXNAV
S80.

Class: Options for Touring, Ultralight, World, Doubleseater, Club, 18-meter, 15-meter,
Open, Standard, and Unknown are available.

a, b, c: Options can be adjusted or entered for a non-listed glider.
Stall speed is used to generate stall warnings which are available with integrated Voice

module.
Reference load (wing loading) value represents the value at which the polar was
measured.

Reference weight corresponds to the weight value at which the polar was measured.
Maximum takeoff .weight is the maximum take-off weight allowed for the glider. It is

not used in the calculation; it is just a reminder to the pilot of the maximum take-off weight.

Empty weight is weight of the glider without the pilot and ballast.
Empty glider weight is a weight of empty glider. This number can be found in a glider

book.

Pilot weight is the weight of the pilot with parachute and baggage.
Co Pilot Weight is the weight of the co-pilot with parachute and baggage.

6 Variometer and Altimeter

All signals from the pneumatic sensors (altitude, speed) are derived from high quality
pressure sensors which mean that no flask is necessary. The vario signal is derived from the
altitude signal. All signals are temperature and altitude compensated. The colour display
show the vario information as well as many other parameters.
The display is user configurable. The Variometer can be configured to show:

• Range 5, 10 and 2.5 m/s or 10, 20 and 5 kts.

• Time constants 0.1 s to 5 s, in addition there are 4 settings for electronic processing

for the vario signal.

• Netto shows the air mass lift and sink.

• Relative shows the lift or sink that would be achieved if the glider was circling at the

thermaling speed.

There are two ways by which the vario indications can be corrected for total energy.
Electronic TE compensation based on speed changes with time and pneumatic compensation
with a TE probe. The quality of the TE compensation depends entirely on the location, size
and dimension of the TE tube. The installation must be leak-proof.

If an electronic TE compensation is selected the TE (Pst) port should be connected
to a good static pressure source. If pneumatic compensation is selected the TE
(Pst) port should be connected to the TE probe.

6.1 Altimeter

The altimeter of the LXNAV S80 is temperature compensated from -20ºC up to + 60ºC. The
altimeter is calibrated up to 20000 m.

6.2 Speed Command

Speed command flying based on the MacCready theory is a very useful tool to optimise
cross-country speed. There are many visual indicators (see Error! Reference source not
found.). When the instrument changes to speed command mode the audio will change and
become a director informing the pilot whether he is flying too fast or too slow. In order to
reduce confusion between vario and speed command audio some special features are
incorporated

• Continuous audio signal in + possible (other kinds of signals can be chosen, see
setup).

• No audio at correct speed (dead band).

7 Flying with the LXNAV S80

To get the best out of the LXNAV S80 it is important that some preparation is done prior to
take-off. Trying to configure the instrument or set a task while flying is very hazardous
especially in a competition. Pre-flight preparation will ensure that the flight will be both safe
and enjoyable.

7.1 On the Ground

7.1.1 Power on Procedure

Press any of the rotary or push buttons to start the LXNAV S80. The LXNAV S80 welcome
screen will appear. The first screen shows the version of the boot loader, firmware,
hardware and serial number. The boot procedure normally takes a few seconds. When
completed, the Set Elevation dialogue is shown.

7.1.2 Set Elevation and QNH

This setting is crucial for final glide calculation: therefore please pay careful attention to it.

The instrument will offer elevation over standard pressure level QNE. Use the knob to fine­tune the elevation.
The QNH should be changed only when airfield elevation and QNH pressure are given. This
might happen in some competitions.
In all other cases the elevation should always match QNH pressure.

The Set Elevation dialogues are not shown if the LXNAV S80 is switched off and on
during flight.

S80 Version 4.92 November 2014

Page 49 of 61

7.1.3 Pre-flight Check

After elevation setup the LXNAV S80 will switch to the Info screen for normal operation
mode.

It is recommended that you scroll to the Flarm, Waypoint or Task Screen and set the
MacCready, ballast and bugs settings to match the current glider configuration.

When you are in either, the Flarm, Waypoint or Task screen, Press the bottom rotary button.
The dialogue for MacCready, Ballast and Bugs will appear.

Use the bottom rotary knob to modify the MacCready setting.Error! Reference source not
found.
It is also highly recommended to check the safety altitude setting. Refer to Error!

Reference source not found. to find out how to define the safety altitude.

7.2 Airborne

7.2.1 Final glide calculation

Final glide is a function calculated from the target distance, target elevation, altitude, wind
component, MC setting and Bug setting. The S80 will have enough information to calculate
this automatically as long as a GPS source is attached and the target to navigate to is set in
Waypoint or Task screen.

The LXNAV S80 is connected to 12 Volt power via the 15-pin SUB-D connector. Optionally
LXNAV S80D can be connected via the CAN bus and the connectors are labelled with “CAN”
at each end.

Instrument has no internal fuse. 3A external fuse is required! Power supply
cables should use a minimum of 0.5 mm² wires.

8.1 Installing the LXNAV S80

The LXNAV S80 vario should be mounted in a standard 80 mm hole.

Remove the two rotary knob caps with a knife or flat screw driver, then hold each knob and
unscrew it.
Remove the remaining two screws and the two M6 threaded nuts. Install S80 into the panel,
screw back all screws, nuts and knobs. Make sure that between the knobs and the panel
there is some space, to push button.

Be sure that LXNAV S80 is placed far enough from compass.

8.2 Connecting LXNAV S80

LXNAV S80 is connected to 12V DC power supply. Red wire goes to + positive and blue wire
goes to – ground. If you don’t use S80D (second seat unit) The Can connector should be left
terminated with a CAN terminator. The SC cable is used for external switch, for switching
between climb and cruise mode.

8.5.1 S80D option (S80 repeater)

In two-seat gliders it is possible to install the LXNAV S80D rear seat device. The S80D looks
almost identical to the S80. In fact it runs on exactly the same software as on first seat
device.
The basic idea of the two-seat configuration is that both devices work independently from
each other with the possibility of automatically exchanging various pieces of data (volume,
Mc, polar…).

8.5.1.1 Data Exchange

All data is exchanged between front and rear unit. LXNAV S80 also exchanges data with GPS
and PDA. Change of MC, Bal, Bugs, Volume, polar settings,... on PDA, will also influence on
LXNAV S80. The Same will happen also in opposite way.

8.5.1.2 Cable Wiring (LXNAV S80D)

8.5.2 Magnetic compass (Compass -CAN)

Is simply connected to CAN bus, main unit will recognize it. In the moment is not available.

8.5.3 Remote stick (Remote-CAN)

Remote stick is also connected to CAN bus. On S80 is provided special menu to register
remote stick. Device must be registered in case of double seat device, there is possible to
have two remote stick, one registered on front and another on rear device.
