2 Basics

2.1 The LX9xx/LX80xx series at a glance

The system consists of two units; the main display unit and the vario unit. Within the main
display unit an integral 50-channel GPS receiver and a high brightness colour display are
fitted. An integrated SD card or USB interface is used for user friendly data exchange.
Some of the models are featuring also PDA port for easy connection on external PDA device.
The main display unit is equipped with a built-in flight recorder according to the most recent
IGC specification for all flights. Optionally the FLARM collision avoidance system can be
integrated into the main display unit.
Main display unit came in different forms:

LX8080 model with 2.8” screen and 320x240 pixels resolution,
LX8000 model with 3.5” screen and 320x240 pixels resolution,
LX9050 model with 5.0” screen and 800x480 pixels resolution,
LX9000 model with 5.6” screen and 640x480 pixels resolution

and
LX9070 model with 7.0” screen and 800x480 pixels resolution.

Standard part of system is also the V9 vario unit. It is a most modern variometer running
on very powerful processor with inertial platform using 3 axis accelerometer, 4 gyroscopes
(for inertial vario, AHRS and wind calculation), smooth audio output with audio equalizer and
integrated synthesized speech output. The unit communicates with the main display unit
over the RS485 system bus. V9 vario features 57 mm diameter (2¼") indicator with
mechanical needle and colour display for additional data.
Optional vario units are available:
V80 vario features 80 mm diameter (3”) colour screen and three additional buttons or V8
vario with 57 mm diameter (3”) colour screen and three additional buttons. Sensors in both
options are same as in V9 variometer.
Optionally additional vario indicators and a wide range of interface devices can be daisy­chained using the RS485 bus.

2.1.5 Interfaces

 The RS232 interface has NMEA output for external devices.
 An SD Card interface.
 A USB slot for data transfer using USB memory stick.

2.1.6 Internal Options

Flarm module can be built into the main display unit. All necessary connectors are

available on the rear side of the unit (Flarm external indicator, Flarm antenna), which
guaranties the same comfort as with the original Flarm devices. It is very important to point
out that the whole system uses only one GPS receiver and therefore offers a low power
solution.
Artificial horizon can be enabled on main display unit. Vario sensor box is constantly
using data from inertial platform in order to make vario signal smoother, however if pilot
would like to see artificial horizon and software option to do so must be purchased.

2.1.7 External Options

By using a RS485 bus system a wide range of optional interfaces can be easily connected to
the basic configuration with minimal installation work. The LXNAV bus system can be
extended easily by use of RS485 splitting units, which allow plug and play connection of
optional devices. The following units can be connected to the main system:

 Second Seat Device (LX9000D, LX9050D LX9070D LX8000D or LX8080D):

The unit installed in the rear seat of the glider is powered and receives all necessary

LX90xx/LX80xx Version 5.0 June 2015

Page 13 of 166

data from the main unit. The communication between both units is exclusively via the
RS485 bus system.

 Remote Control: An extremely ergonomic leather-coated handle which includes 8

push buttons to operate the main display unit and also two additional buttons with open
wires. These two buttons can be used for instance as PTT for radio and SC/Vario
changeover command. A second remote control can be installed to control second seat
device or for side by side operation.

 Electrical Compass Device
 Secondary Vario Indicators (I8,I9 or I80 indicator)
 Flap sensor
 MOP box for jet engines

2.1.8 Simulator

There are two options to stay in condition and familiar with your system. LXSim is free of
charge program, which you can download from www.lxnav.com or data from the Condor PC
flight simulator (www.condorsoaring.com) can be received via the RS232 port after entering
suitable passwords (see Chapter 5.1.15).
These features are extremely useful for pilots who want to learn about the system and also
wish to refresh their knowledge after a winter break. Please note that altitude data will be
sent from the simulator which means that real final glide training will be possible.

4.1.2 Portrait orientation

The V9 vario unit is an indicator only and has no controls. Information displayed
is controlled by the main display unit.

The V80 vario unit is having three buttons to toggle between screens. More
information is given in chapter 5.1.12.4.

4.1.3 Buttons

All buttons have a dynamic function; the first time one presses each button, it displays its
function without executing any action. Not all buttons have a function on every page. In
some cases buttons have a long press function.

4.1.3.1 Power Button

The power button is marked with the ON/OFF symbol. It has multiple functions. Primarily it
is used to switch the system on and off.

4.1.4 Rotary Switches (Knobs)

The main display unit has four rotary knobs. Each has a single function with the exception
of the zoom knob which has, in some cases, a function other than zoom. With the upper­left rotary knob the volume can be adjusted. The upper-right rotary switch is the mode
selector (it changes the mode of the operation). At the lower-right is the up/down knob
which is used for selecting sub-pages, sub-menus and editing menus. At the lower-left is
the zoom knob which is multifunctional. While its main function is to change the zoom level
within graphic mode, it can also be used if an error is made during editing; it is possible to
move the cursor back by rotating this knob. However this can only be done if 'editing' is
active which is shown by the cursor blinking.

4.3.9 Pull down menu

Pull down menu is used to select one of the options. Press button several times to select
appropriate item of turn PAGE selector knob. Pull down menu will automatically close after
few seconds.

4.4 Switching off

Please use one of the following recommended methods for shutting down the LX90xx
system:

Method 1

Press the button with the OFF label which is displayed in navigational modes. See Chapter

5.5 for more details. A message to confirm shutdown will be shown.

Method 2

Press the button with the OFF symbol for approximately 4 seconds. The OFF message will
be displayed and the instrument will shut down. When the message appears you must
release the power button.

LX90xx/LX80xx Version 5.0 June 2015

Page 26 of 166

Method 3

When the button with the OFF symbol is pressed for more than 8 seconds the system will
perform an unconditional shutdown. This method is recommended only in case that the
program hangs and it is not possible to shutdown with methods 1 or 2.

If you are using method 2 to switch off the system it is necessary to release the
button when you see the shutting down message. If you continue to press the off
button the main display unit may shut down by method 3.

If the request for OFF is made during flight the instrument will ask for confirmation so that
the system cannot be switched off by mistake.

It is important that the main display unit is switched off via software. Never
power down the system using the main power switch. The main display unit is
running the Linux operating system and sudden power loss may corrupt the file
system.

If main power is lost for a few seconds during flight the flight recorder will not
produce two flights. The most important flight parameter (altitude) will remain
which means that the final glide calculations are not affected.

5 Operating Modes

The main display unit has seven modes or main menus. All of them are selectable by
rotating the upper-right knob which is also called MODE selector. The diagram below
shows the mode structure of the LX9000 running in portrait screen.

 Airport Mode, navigation and selection airports.
 Waypoint Mode, navigation, selection and editing waypoints.
 Task Mode, Navigation, selection and editing task.
 Statistics Mode shows statistical data for flight in progress or logbook.
 Setup mode is used to configure the whole system.
 Information Mode displays GPS status, altitude, flight level and height, sunrise and

sunset or position report to selectable point or satellite sky view.

 Near Mode displays a list of all landable waypoints and airports.

The Navigation modes and statistics mode have additional pages which are accessible by
rotating the bottom-right knob also called the PAGE selector.

LX90xx/LX80xx Version 5.0 June 2015

Page 28 of 166

Three main navigational modes airport, waypoint and task mode are selected by
rotating the upper-right knob. All three options are similar and have similar basic navigation
data screens accessed by rotating the bottom-right knob.

It is possible to fully customise all three main navigational pages using the
program LXStyler. This program can be downloaded from our webpage

www.lxnav.com. Refer to Chapter 5.1.14 for more details.

It is also possible to customise selected navigational pages using STYLE menu
option. Refer to Chapter 6 for more details.

In airport navigation mode the user can navigate only to airports stored in LXNAV's Airports
database. This database cannot be edited on device itself and is available at no charge on
our web pages. See Chapter 5.1.5.2 for more details how to obtain the latest databases.

Database can be modified using program LXAsapt editor. This program can be
downloaded from our webpage www.lxnav.com

In waypoint navigation mode the user is navigating to waypoints that were previously
loaded and selected in the Files and Transfer menu (see Chapter 5.1.5.4).
Task navigation mode is used for task creation and manipulation. Navigation in this page is
exclusively to task points.

5.1 Setup Mode

In the setup menu users can configure the main display unit and connected devices. Turn
the bottom-right knob - PAGE selector - or press the UP/DOWN arrow on the remote stick to
select the appropriate setup item. Turn the bottom-left knob - ZOOM selector - or press the
LEFT/RIGHT arrow on the remote stick to move faster over menu. Press the SELECT
button or push middle multi-directional button on the remote stick to enter a menu. A
dialogue or sub-menu will open.

The setup menu is slightly different on the rear seat device as not all options are applicable.
Items which are marked with an asterisk (*) are available only in the front seat setup menu.

5.1.1 QNH and RES

Turn the bottom-right knob to select the required entry field. Press the EDIT button and
start editing the value.

5.1.1.1 QNH*

Using this feature it is possible to offset the altitude datum which could have changed due
to pressure changes during the flight. Since changing the QNH influences the indicated
altitude, care should be taken when changing the value as an incorrect setting can upset the
final glide calculation.

LX90xx/LX80xx Version 5.0 June 2015

Page 30 of 166

5.1.1.2 Safety Altitude

This setting is the altitude reserve or safety altitude and is the height that the instrument
adds to the final glide altitude required so that 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.

5.1.1.3 Altitude source

The system has two pressure altitude sensors. One is built into the main display unit and is
used for the IGC recorder and the second one is built into the vario unit and is connected to
the glider pitot-static system. Changing the altitude source defines which sensor is used for
pressure altitude used in program.

5.1.1.4 Magnetic Variation

The main display unit has a built-in Earth magnetic field model. If Auto variation is checked
the magnetic variation is derived from this model, otherwise the user can enter a custom
value.

5.1.1.5 ETA/ETE Calculation

In changing this value you may choose from four different methods to calculate the
estimated time of arrival to the navigational point. Calculation is always divided into straight
flight and climb time calculations.
 MacCready uses the Polar data and MacCready setting to calculate speed to fly and

climb rate.

 Vario uses the last four thermals average to compute climb rate and uses this value to

calculate speed to fly.

 Avg.Speed & Vario uses the average ground speed over the last 5 minutes for

distance and Vario statistics for climb rate.

 Avg.Speed & MC uses the average ground speed over the last 5 minutes for distance

and MacCready.
All four methods of calculating ETA and ETE (Estimate Time of Arrival & Estimate Time
Elapsed) take into account glider altitude, wind and safety (arrival) altitude thus ensuring
that the calculation made is the best possible.

Suggested methods for competition pilots are Avg.Speed & Vario or

Avg.Speed & Mc.

5.1.1.6 Soaring Start*

Soaring start is the time when the glider starts soaring (released from tow, engine switched
off). A soaring start time is needed to start the flight optimization.
