3.1.4 Options
3.1.4.1 Internal options
If ordered, integrated Flarm electronics can be built in to the LX8000 digital unit. All
necessary connectors are available on the rear side of the unit (Flarm external indicator,
Flarm antenna), which guaranties minimum the same comfort like using of 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 bicolor LED Flarm External display is an apart
of delivery, extension to 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, without any significant installation works. The LX 8000 bus system
can be extended easily by use of RS485 splitting units, which allow plug and play connection
of optional devices. Following units can be connected to LX 8000 bus system:
•Second seat device (LX7007D or LX8000D – available in 2009). 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 RS485 bus
system.
•Remote control. An extremely ergonomic leather coated handle which includes 8 push
buttons to operate LX 8000 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.
•Electrical compass device
•Secondary LCD indicators
•Voice Module, to express information and warnings by voice
•Simulator. Condor PC flight simulator (www.condorsoaring.com) data can be received
via RS232 port after input of suitable passwords (See chapter 5.1.15). This feature is
extremely useful for the pilots who want to learn about LX8000 and also like refreshment
after winter period. Please note that altitude data will be sent from the simulator,
meaning that real final glide training will be possible.

4.4 Switching off
Please use one of recommended methods for shutting down LX8000.
Method 1
Press button having the OFF label which is displayed in navigational modes. See chapter 5.5
for more details. Message to confirm shutdown will be shown.
Method 2
Press button with off symbol for approximately 4 seconds. OFF message will be displayed
and instrument will shut down. When message appears, you can release the power button.
Method 3
When button with off symbol is pressed for more than 8 seconds, LX80000 will unconditional
shutdown. This method is recommended only in case that LX8000 program hangs and it is
not possible to shutdown with methods 1 or 2.
In case that request for OFF is made during flight, the instrument will ask for confirmation so
the LX 8000 can not be switched off by mistake.
It is important LX8000 is switched off using software. Never power down LX8000
using main power switch. LX8000 is running Linux operating system and sudden
power loss may corrupt file system.
During flight, if main power is lost for a few seconds, the flight recorder will not
produce two flights. The most important flight parameter, altitude will remain,
which means that the final glide is not interrupted.

LX8000 version 0.96 April 2008
Page 17 of 85
5Operating modes
The LX8000 has 7 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 LX8000.
•Information mode displays GPS status, altitude, flight level and height, sunrise and
sunset.
•Near mode shows list of all landable waypoints and airports.
•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 LX8000
Navigation modes and statistics mode have more pages, which are accessible by rotating the
bottom-right knob also called PAGE selector
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 bottom-right knob.
In airport navigation mode the user can navigate only to airports stored in LX navigation
Airports database. This database can not be edited and is available, free, on our web pages.
See chapter 5.1.5.2 for more details how to obtain latest databases.
In waypoint navigation mode user is navigating to waypoints that were previously loaded
and selected in 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
done exclusively to task points.

LX8000 version 0.96 April 2008
Page 18 of 85
5.1 Setup mode
In setup menu users can configure LX8000. Turn bottom-right knob or press UP/DOWN
arrow on remote stick to select appropriate setup item. Press SELECT button or CHECK
button on remote stick to enter menu. A dialog or sub-menu will open.
5.1.1 QNH and RES
Turn bottom-right knob to select entry field. Press EDIT button and start editing 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. As 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
destination at the selected safety altitude. After safety altitude input, the pilot has to keep
final glide indicator on 0 to arrive on safety altitude.
5.1.1.3 Magnetic variation
LX8000 has a built in an Earth magnetic field model. If check Auto variation is selected, then
magnetic variation is derived from this model, otherwise user can enter custom value.
5.1.1.4 ETA/ETE calculation based on.
In changing this value you may choose from four different ways to calculate estimated time
of arrival to the navigational point. Calculation is always divided into straight flight and climb
time calculations.
•MacCready setting 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.

LX8000 version 0.96 April 2008
Page 19 of 85
•Avg.Speed & Vario uses the average groundspeed over the last 5 minutes for distance
and Vario statistics for climb rate.
•Avg.Speed & MC uses the average groundspeed 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 available
Suggested method for competition pilots are Avg.Speed & Vario or Avg.Speed &
Mc
5.1.1.5 Soaring start
Soaring start is time when glider starts soaring (released from tow, engine switched off)
Soaring start time is needed to start flight optimization.
5.1.2 Flight recorder
LX8000 digital unit has built in a fully approved flight recorder by the IGC (A sub-committee
of the FAI.) and will produce secure flight records that are acceptable for all FAI
requirements including world records. (Note: as at April 08 approval is in progress)
Select recording interval, enter pilot name. Pilot weight is important if ballast is given in
kilograms of water. (See chapter 5.1.11). If LX8000 is used in double seater the name of
copilot can also be entered.
There is no setup for glider type. Glider type is defined in Polar and Glider setup
(see chapter 5.1.14)
Compared to previous LX instruments (LX20, LX5000 and LX7007) there are less
settings for flight recorder. This is because LX8000 will record all additional data
such as (wind, speed, vertical speed) by default.

LX8000 version 0.96 April 2008
Page 20 of 85
If new pilot is entered, on dialog exit, message “Do you to create new profile?” will be asked.
Answer YES if you want quickly to add new profile. For more information about profiles see
chapter 5.1.12.
5.1.3 Vario parameters
The following parameters can be set using this option.
On that page following parameters are set:
Vario needle filter sets a time constant of vario needle. Value can be adjusted between
0.1 and 5s with step 1.0s or 0.1s. Default value is 1.5s.
Vario sound filter sets a time constant of vario sound. Value can be adjusted between 0.1
and 5s with step 1.0s or 0.1s. Default value is 1.5s.
Vario range sets full scale range of vario (2.5m/s, 5m/s or 10m/s). Default value is 5m/s
(10kts).
SC tab defines the width of the audio dead band in speed to fly mode. Default value is
±1m/s.
Integrator time defines integration period for the average vario in seconds. The default is
20 seconds.
Auto SC defines the conditions, by which the instrument is switched automatically between
vario and speed command.
•OFF: Switching is possible exclusively by an external switch, connected to the LX 8000
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 a straight flight will cause a
change over to speed command.
