3 Basics
3.1 The LX9000 at a Glance
The instrument consists of two units; the LX9000 digital unit and the vario unit. Within the
LX9000 digital unit an integral 16-channel GPS receiver and a high brightness colour display
with 640 x 480 pixels are fitted. An integrated SD card or USB interface is used for user
friendly data exchange. The LX9000 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 LX9000 digital unit.
The 57 mm diameter (2¼") LXNAV V5 vario unit is a modern designed variometer with its
own processor. It features an mechanical needle with colour display for additional data.
The unit communicates with the LX9000 digital unit over the RS485 system bus. Optionally
additional vario indicators and a wide range of interface devices can be daisy-chained using
the RS485 bus.
3.1.1 Display Unit Features

3.1.4 Options
3.1.4.1 Internal Options
Integrated Flarm electronics can be built into the LX9000 digital 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. One bicolour LED Flarm External display is included in the
delivery; extension to a second seat is possible.
3.1.4.2 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 LX9000 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 LX9000 bus system:
• Second Seat Device (LX9000D, LX8000D or LX8080D): The unit installed in the
rear seat of the glider is powered and receives all necessary 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 LX9000 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.

Rotating the zoom selector changes colour transparency. Transparency is very important for
fill colours which are used for airspace zones, observation zones and FAI area. If a fill colour
is not transparent (0%), all other map items will not be seen through it. If a fill colour is
100% only the solid border will be drawn.
4.3.7 Font Selector
Using the font selector it is possible to define a font colour and style for a selected item.
Turn the lower-right knob (page-selector) to change the font style. Text is also rendered in
the selected font style. Turn the lower-left knob (zoom-selector) to change the font colour.
LX9000 Version 2.6 September 2011
Page 18 of 130
4.4 Switching off
Please use one of the following recommended methods for shutting down the LX9000:
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.
Method 3
When the button with the OFF symbol is pressed for more than 8 seconds the LX90000 will
perform an unconditional shutdown. This method is recommended only in case that the
LX9000 program hangs and it is not possible to shutdown with methods 1 or 2.
If you are using method 2 to switch off the LX9000 it is necessary to release the
button when you see the shutting down message. If you continue to press the off
button the LX9000 may shut down by method 3.
LX9000 Version 2.6 September 2011
Page 19 of 130
If the request for OFF is made during flight the instrument will ask for confirmation so that
the LX9000 cannot be switched off by mistake.
It is important that the LX9000 is switched off via software. Never power down
the LX9000 using the main power switch. The LX9000 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
.

SELECT button or CHECK button on the remote stick to enter a menu. A dialogue or submenu 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.
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
LX9000 Version 2.6 September 2011

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 Magnetic Variation
The LX9000 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.
5.1.1.4 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.
5.1.1.5 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.

5.1.2 Flight Recorder
The LX9000 digital unit has a built-in flight recorder fully approved by the IGC (a subcommittee of the FAI) and will produce secure flight records that are acceptable for all FAI
requirements including world records.
Select the recording interval and enter the pilot name. Pilot weight is important if ballast is
specified in kilograms of water (see Chapter 5.1.11). If the LX9000 is used in two-seat
aircraft the name of the co-pilot may also be entered.
There is no setup for glider type. Glider type is defined in the Polar and Glider
setup (see Chapter 5.1.13).
There are very few settings for the flight recorder compared to other instruments.
This is because the LX9000 will record all additional data such as wind, speed and
vertical speed by default.
If a new pilot is entered, upon exiting the dialogue the message
“Do you want to create new
profile with this pilot?”
will be asked. Answer YES if you want to quickly add a new profile.
For more information about profiles see Chapter 5.1.12.

5.1.3 Vario Parameters*
This option is used to set the following parameters:
On this page the following parameters are set:
Vario needle filter sets a time constant of the vario 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.
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.
Vario range 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).
SC tab defines the width of the audio dead band in speed to fly mode. Default value is
±1 m/s.
Integrator time defines the integration period for the average vario in seconds. The
default is 20 seconds.
Auto SC defines the conditions when the instrument is switched automatically between
vario and speed command.
• OFF: Switching is exclusively by an external switch connected to the vario unit.
• 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).
Using Smart vario filter, vertical speed can be further filtered. Behaviour of filter is
different for types of attached variometer:
On V5 variometer smart vario filter defines how much filter is different for increasing vertical
speed versus decreasing vertical speed. (E.g.: If vario filter is set to 1s and Smart vario filter
is set to 4, then filter for increasing vario be 1s and for decreasing vario it will be 2s). This
will produce an effect like on Sage variometer.
On older models of variometer smart filter value gives us four levels of dynamic damping of
the vario.
Auto reset integrator resets the integrator to zero when the LX9000VU switches from SC
to VARIO mode. If this item is not checked the integrator will not be reset to zero (this
function is supported with LX9000VU version 2.05 or higher).
The external switch wired to the vario unit has absolute priority and will override
all other switching methods.

5.1.4 Display
The display menu controls screen brightness. The LX9000 has an ambient light sensor which
detects ambient light and automatically increases or reduces the brightness of the screen.
If the Automatic brightness checkbox is selected, the instrument will automatically adjust
brightness according to current light conditions. Minimum and Maximum brightness
items control value limits. Use time values to setup how fast adaptation to brighter
conditions or darker conditions will occur. Default values are tuned to human eyes and do
not require change.
Night mode brightness defines maximum brightness when instrument is operating in
night mode. In night mode, brightness is reduced to very low value to reduce difference
between ambient light and device backlit.
If you want to set the brightness manually uncheck the Automatic brightness control and
set the brightness manually.
Change Display orientation if you would like to change the LX9000 screen orientation.
The LX9000 will restart and start with new screen orientation.
It is recommended that the automatic brightness control is always enabled.
Reducing brightness will also reduce power consumption. See technical data for
more details (Chapter 3.1.5).
