2 Basics
2.1 The LX9xx series at a glance
LX9xx series of instrument 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. 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 two different forms:
LX9000 model with 5.6” screen and 640x480 pixels resolution,
And
LX9070 model with 7.0” screen and 800x480 pixels resolution.
The V9 vario unit 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.
Standard version of V9 variometer features 57 mm diameter (2¼") indicator with
mechanical needle and colour display for additional data. Optional variometer consists of
80 mm diameter (3”) indicator called V80 which has colour screen only with three additional

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. V9 variometer 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.

Page 13 of 151
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, LX9070D 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 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 (V5 indicator or V80 indicator)
• Flap sensor
• MOP box for jet engines

2.1.8 Simulator
There are two options to stay in condition and familiar with your LX90xx 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 6.1.15).
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.

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.
LX90xx system Version 4.0 February 2014
Page 29 of 151
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
.

LX90xx system Version 4.0 February 2014
Page 31 of 151
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 6.1.14 for more details.
It is also possible to customise selected navigational pages using STYLE menu
option. Refer to Chapter 7 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 6.1.5.2 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 6.1.5.4).
Task navigation mode is used for task creation and manipulation. Navigation in this page is
exclusively to task points.
LX90xx system Version 4.0 February 2014
Page 32 of 151
6.1 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.
6.1.1 QNH and RES
Turn the bottom-right knob to select the required entry field. Press the EDIT button and
start editing the value.
6.1.1.1 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 system Version 4.0 February 2014
Page 33 of 151
6.1.1.2 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.
6.1.1.3 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.
6.1.1.4 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.
6.1.1.5 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.
6.1.1.6 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.
LX90xx system Version 4.0 February 2014
Page 34 of 151
6.1.2 Flight Recorder
The main display 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 6.1.11). If the system 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 6.1.13).
There are very few settings for the flight recorder compared to other instruments.
This is because main display unit 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 6.1.12.
LX90xx system Version 4.0 February 2014
Page 35 of 151
6.1.3 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.
• G-load: When accelerometer detects increased g-load, because of circling, variometer
will change from cruise to climb mode.
• IAS: When the IAS exceeds a pre-set value. The IAS 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. Smart vario filter defines
maximum speed of vario needle. Higher the value is, slower will be the needle.
Beep at max will enable a short beep few seconds before a maximum in thermal is
reached.
Beep before max defines how many seconds before a maximum in thermal a short beep
will be heard.
Auto reset integrator resets the integrator to zero when the vario unit switches from
cruise to climb mode. If this item is not checked the integrator will not be reset to zero.
Netto filter sets a time constant of the netto vertical speed filter. The value can be up to
20 times bigger than vario needle filter. Default value is same as vario needle filter.
SC filter sets a time constant of the speed to fly (SC) filter. The value can be up to 20
times bigger than vario needle filter. Default value is same as vario needle filter.
LX90xx system Version 4.0 February 2014
Page 36 of 151
Relative filter sets a time constant of relative vertical speed filter (also known as supper
netto vertical speed). The value can be up to 20 times bigger than vario needle filter.
Default value is same as vario needle filter.
Netto time defines the integration period for the average netto vertical speed in seconds.
The default is 20 seconds.
The external switch wired to the vario unit has absolute priority and will override
all other switching methods.
6.1.4 Display
The display menu controls screen brightness. The main display unit 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 display unit screen orientation.
The main display unit will restart and start with new screen orientation.
Checking Auto brightness on vario while enable automatic regulation of brightness on
vario unit, if available. It this option is uncheck, vario unit will always run at full backlight.
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 2.1.9).

LX Asapt Editor allows you to edit any LXNAV airport database distributed as asapt files. You
can quickly filter the regions and find the airports you're interested in. View and edit all
details of the airports, add charts, photos (from files or clipboard) and any other information
you would like associated with them. You can also delete the regions you're not interested in
and add any new or missing airports anywhere in the world (for supported regions). The
application also monitors every change you make to the database, so you can simply apply
changes to a new database when it is released by LXNAV.
Modified airport data can readily be exported to the system as a (asapt) file and imported to
the main display unit using the standard procedure for database updates (see Chapter
6.1.5.2).
The original database can be restored only via the update database procedure using the
original database file. All databases are published on www.lxnav.com .

6.1.5.7 Managing Maps
Main display unit is preloaded with terrain and vector map data for complete Earth. However
it is also possible to use scanned (rasterized) maps as background of navigational screen.
Next two images are showing example of scanned ICAO map and satellite imagery.
The system is supporting two file formats: CMR file format provided by SeeYou software
from Naviter. There are available free of charge sectional maps of USA
(www.soaringdata.info) and QMP file format provided by Ifos. Please contact Ifos
(www.ifos.de) or (www.strepla.de) to purchase scanned maps.
Select the Maps menu item and press the SELECT button. A list of all available map files
will be shown on the screen.
Multiple files can be selected. All checked files will be shown on navigational page depend
on raster map setting (See chapter 6.1.6.1 and 6.5.6.3).
Press DELETE button to remove selected map. Press LOAD button to upload selected map
to internal memory.

When a map file from USB or SD card is selected, it will be available only, if SD
card or USB stick is inserted in main display unit.
Map files can be very big in size and can occupy a lot of space of internal storage
of main display unit. Selecting maps directly from SD card or USB allows you to
save space at no performance cost and create portable profiles, which can be
transferred from one device to another device.
6.1.5.8 Managing Flights
Select the Flights menu item and press the SELECT button. A list of all stored flights will
be shown. The main display unit is capable of storing more than 1000 hours of flight logs.
If a SD card or USB stick is inserted into the main display unit, flights can be copied to it
when the corresponded button is pressed. Flights can be removed from the main display
unit using the DELETE button.
6.1.5.9 Flight Declaration
The Flight Declaration is composed from pilot data and declared task. Use this option if you
wish to load or save a flight declaration from a file. The flight declaration is saved into
binary HDR file.

transfer declaration to Nano flight recorder.
Please note that not all data from the HDR file will be loaded. Glider type and
class must be changed via the Polar and Glider menu (Chapter 6.1.13) as also
final glide calculations are linked to this setting.
HDR files do not include information about observation zone and turn point
elevation. Observation zones will be set to default values (Chapter 6.1.8) and the
elevation will be defined by the digital elevation model built into the instrument.
6.1.5.10 Formatting a SD Card
Use this option if the main display unit cannot read SD card. The system uses the same
card format as used by the MS-Windows operating system (FAT). However sometimes
Windows does not format the SD card properly or a new card may not be formatted
properly. It is recommended to format new SD cards before using them.
Formatting a SD Card will erase the entire contents of the SD card.
6.1.5.11 Managing PDF documents
Main display unit can store almost unlimited number of PDF documents. User can store here
flight manual, maintenance manual, scans of all gliding documents and also checklists.
Select the PDF READER menu item and press the SELECT button. A list of all available
PDF documents will be shown on the screen. Select desired document using PAGE selector.
Press DELETE button to delete selected document. Press LOAD button to upload selected
document to internal memory.

6.1.6 Graphics
This dialogue allows the user to define the appearance of the map in navigational mode.
Select the Graphics menu item and press the SELECT button. A submenu will open.
6.1.6.1 Terrain and Map
The main display unit is pre-loaded with terrain and vector maps for the Earth. The
database includes: elevation contour lines, water bodies, roads, highways, railways, big
cities and a digital elevation model. The database is derived from the OSM free database.
The database cannot be modified by the user.
Check the Show map item to enable map displays in the navigational pages. If this item is
unchecked no map will be displayed. Check Shadows, if you terrain to be shaded. The
Label zoom value defines up to which scale of zoom city names are visible. 100km means
the whole width of the screen represents 100 km. The user can also modify size, font style
and colour via the Font style and colour item. Use the ZOOM selector knob to modify the
colour and the PAGE selector knob to modify the style. Press PICK button to define colour
more precisely.
Terrain can be rendered in three different levels. A higher level means more details. The
main display unit is optimised to work with high terrain quality. If the value off is selected
no terrain will be shown; only water bodies, roads, railways and cities.
The background colour is defined by the Background item. The default background is
black.
LX90xx system Version 4.0 February 2014
Page 48 of 151
Colours of terrain can be changed using different terrain colour schemes. The following
colour schemes are available:
• Mountain is default setting with colours from green to white at 2000 m.
• Flatland is setting where colours are changing up to 1000 m.
• Low contrast: same as Mountain but colours are not so intensive.
• High contrast: same as Mountain but colours are more intensive and from 0-100 m,
white colour is used.
• Zebra alternating colours are used.
• Zebra 2, less intensive alternating colours are used.
• ICAO colouring is similar to ICAO maps.
• Cliffs colours emphasis slopes and is similar to Google maps display
• Atlas colour scheme is approximation of Imhof colouring widely used in map books.
• Grayscale.
In the Elements group land features are setup separately. Zoom defines up to which
zoom level a selected land feature is visible. Also line width and colour can be setup.
Press the DEFAULT button to reset these settings back to default.
If you have checked shadows and you are flying on flat areas with elevation close
to MSL or below, on terrain will be displayed black spots. Black spots will
disappear, if you uncheck shadows.
Check Show raster maps, if you would like to see also scanned maps (See also
chapter 6.1.5.7).
6.1.6.2 Airspace
In this dialogue you can define the airspace map presentation. Check the Show airspace
item to enable airspace displays in navigational pages. If this item is unchecked no airspace
will be displayed.
If the Show inactive zones option is checked then airspace zones with proximity warning
switched off will be shown. Use Show only airspace below to eliminate airspace which is
going to be too high for the day. For example, if the forecasted cloud base is to be 1500 m,
set this value to 1600 m and your screen will be much more readable. In the Type panel
you can specify how each airspace type is displayed. You should define each type of
airspace zone separately. First choose an airspace type from the list. Zoom value defines
to which zoom level this type is going to be visible. The Colour and Width items specify
how selected airspace zone will be drawn. You can also modify transparency of the selected
type. Turn the ZOOM selector knob to change the transparency value. 100% means
LX90xx system Version 4.0 February 2014
Page 49 of 151
completely transparent and only the airspace zone outline will be shown. 0% means
completely solid (not recommended). Image below shows example of combinations of Width
and Colour property and rendering of airspace zone.
Press the DEFAULT button to reset these settings back to default.
6.1.6.3 Waypoints and Airports
The waypoint and airport look and feel is defined in this dialogue. Check the show
waypoints item to enable waypoints and airports display in navigational pages. If this item
is unchecked no waypoints will be displayed.
The Max.visible item defines how long waypoint labels and detailed symbols are shown. If
the maximum number of waypoints on the current screen is more than the defined value
only small blue dots will be shown for waypoints and no labels will be drawn.
Font style, colour and size can be defined using the Font style and colour item and the
Font size item. When editing style, turning the ZOOM selector knob will change the font
colour.
Waypoint labels can be setup to give even more detail. Label details can be defined for
each individual waypoint type.
A label consists of two selectable values: upper label and lower label. If you prefer to have
labels in single line, the single label checkbox should be checked. A label can also be
coloured. Check the Colorize label item. Coloured labels are drawn with a green
background when the waypoint is within range with the current MacCready settings and
with a yellow background when waypoint is within reach with MacCready setting zero. No
background is shown if the waypoint is not reachable.
The label is selected from following options:
• Name: waypoint name is shown. The name length item controls how the name is
displayed.
LX90xx system Version 4.0 February 2014
Page 50 of 151
• Code: will display the ICAO code or short name.
• Elevation: shows waypoint elevation.
• Arrival altitude shows arrival altitude taking into account current MacCready setting,
safety altitude and current wind. Due to complexity of the calculation it will not take the
wind profile into account.
• Required altitude shows how much height is needed to reach the point. Required
altitude takes into account current MacCready setting, safety altitude and current wind.
Due to complexity of the calculation it will not take the wind profile into account.
• Required Mc gives an estimate of the maximum MacCready value which we can use to
reach the point.
• Required L/D shows the required glide ratio to the point taking into account the safety
altitude.
• Frequency will display the point frequency, if available.
Press the DEFAULT button to reset these settings back to default.
6.1.6.4 Glider and Track
Navigational screen can show the coloured path flown, current track vector and target
vector with terrain collision warning.
Check the Show path item if you want to see the flown path. Path length defines how
much of the flown path will be shown. The path can be coloured using:
• Vario path style, where red colour indicates positive vertical speed and blue colour
negative vario values.
• Mc path style, which is based on current MacCready settings. Red colour indicates
segments of the flight where we have vertical speed higher than the current MacCready
setting. Orange colour shows vertical movements similar to the current MacCready
setting and blue for vario values below the MacCready setting. Grey depicts sink areas.
• Fixed path style. Path colour is fixed and defined by path colour item.
• Altitude path style, where red colour means low altitude and blue means high altitude.
• Ground speed path style, where red colour means slow speed and blue colour means
fast speed.
Check the Show current track item if you would like to see your current ground track
vector. Track colour and width defines the colour and width of the current track vector.
Selected target and current position are connected with a magenta line. Check Show
target if you would like to see this line. In the target colour and target width you can
select the Colour and Width of this line. You can also choose to show or hide the terrain
collision point and the target line itself. The terrain collision marker is a red square which is
only displayed when there is terrain between the navigational point and the current position
LX90xx system Version 4.0 February 2014
Page 51 of 151
and therefore not enough altitude to reach the target with the current glider settings. Font
Style, Colour and Size define what font for terrain collision altitude and range circles.
Enable Show range circles to plot range circles around aircraft symbol. Having range
circles on navigational screen, it is much easier to guess distance to nearest point of
interest.
Range colour and range width define the way circles are rendered.
A built in engine noise level sensor detects, if engine is running or not. Use Engine colour
and width properties to visualize part of path, where engine was running.
Press the DEFAULT button to reset these settings back to default.
6.1.6.5 Optimization
The main display unit calculates the optimised flown distance according to OLC or FAI rules
in real-time during flight (see Chapter 6.1.9). It calculates the available FAI triangle area,
which is also called the FAI triangle assistant. If you enter this area and return to the start
point your flight forms a triangle according to FAI rules. The Optimisation dialogue is used
to define the look and feel.
Check the Show optimization item to enable display of the optimised track.
Optimization colour and width defines the colour and width for these lines.
If Show optimized triangle is checked also lines for the largest optimised triangle are
shown. Please note this might not be a triangle according to FAI rules.
The FAI Area group defines how the FAI area is drawn. Select the Colour item to change
the colour of the FAI area. Use the ZOOM selector knob to change transparency of the
area. 100% means completely transparent and only the outline will be drawn. 0% means
completely solid (not recommended).
Check the Show km lines item to see lines which indicate what will be the size of the
completed triangle.
These lines will always be plotted in kilometres scale regardless of the Units value.
LX90xx system Version 4.0 February 2014
Page 52 of 151
6.1.6.6 Task
Use this dialogue to define how a task is drawn in task mode.
Task colour defines the colour of task lines. Obs.zone colour defines colours for
observation zones. Use the ZOOM selector knob to change transparency of area. 100%
means completely transparent and only the outline will be drawn. 0% means completely
solid (not recommended). When Show flown task is checked also the flown task will be
drawn. This might be useful when flying assigned area tasks.
The Show selected zone only item controls whether all task observation zones are to be
displayed or, if there is only one, then that alone will be shown.
6.1.6.7 Flarm
The system can be equipped with the internal or external FLARM module. If your device is
equipped with FLARM this menu will let you to modify presentation of the Flarm radar
display.
Flarm radar is not available if competition or privacy modes are active. Refer to
Chapter 6.1.12.6.
Checking Show Flarm object will enable display of aircraft detected by FLARM.
Colours are designed to present three values. The colour for aircraft more than 100 meters
above your current altitude is defined by the Above Colour item. The colour for aircraft
more than 100 meters below your current altitude is defined by the Below Colour item.
LX90xx system Version 4.0 February 2014
Page 53 of 151
The colour for aircraft that are less than 100 meters below or above your current altitude is
defined by the Near Colour item.
When a signal from a particular aircraft is lost the aircraft remains blinking on the screen for
the duration defined in the Lost device after item (default 120 seconds). After that time
the aircraft symbol will not be displayed.
Show labels combo box defines for which Flarm objects altitude and vertical speed are
displayed next to the aircraft symbol. The user can modify size, font style and colour.
Select the Font style and colour item. Use the ZOOM selector knob to modify colour and
the PAGE selector knob to modify style.
It is possible to display the flown path of tracked aircraft. Path colour and Path width
define width and colour of paths. Show paths combo box defines for which Flarm object
paths are going to be visible.
Symbol size defines size of symbol of Flarm object.
Check Show PCAS to see non-directional traffic on navigational screen. Non-directional
traffic will be draw with dotted circle at received distance from aircraft position.

6.1.7 Sounds*
In the Sounds setup page audio settings, voice settings and alarms settings for the vario
unit can be modified.
6.1.7.1 Audio Settings*
Basically here we can set up two types of audio; audio sound for climb mode and another
for cruise mode (SC).
Vario audio mode has the following options:
• Linear positive: sound is interrupted with silence every few milliseconds when the
needle is positive; on negative side sound is linear (not interrupted).
• Linear negative: inverse function to Linear positive.
• Linear: sound is linear and non-interrupted in full scale range.
• Digital positive: similar to Linear positive, except frequency is not changing linearly
but with larger steps.
• Digital negative: inverse function to Digital positive.
• Linear positive only: sound is present only at positive values, for negative values
there is silence.
• Digital positive only: similar function to Linear positive only, except the sound is
similar to the digital tone.
Press the DEMO button to hear the selected option.
LX90xx system Version 4.0 February 2014
Page 55 of 151
SC audio mode has four modes:
• SC positive: sound is interrupted with silence every few milliseconds when the needle
is positive; on negative side sound is linear (not interrupted).
• SC negative: inverse function to SC positive.
• SC: sound is linear and non-interrupted in full scale range.
• SC Mixed: for positive relative values the sound represents relative; for negative
relative values the sound represents SC (for that setting it is recommended to set SC
needle to relative).
• Netto speed: variometer will produce exactly the same sound as defined in Vario
audio, except it will follow netto vertical speed.
Freq at 0% defines the tone frequency at 0 m/s.
Freq at +100% defines the tone frequency at full + deflection.
Freq at -100% defines the tone frequency at full – deflection.
6.1.7.2 Voice*
Voice module is integrated part of V5, V9 or V80 variometer. The voice module is 100%
controlled through the main display unit via the settings described in this menu.
In the Voice menu volume level (loudness) of the voice module can be adjusted. In the
Messages window each item can be set separately. Only checked items will be played by
the voice module.
Volume level (loudness) can be also set with volume rotary knob, when messages
are being played
6.1.7.3 Alarms*
The vario unit produces an audio alarm on reaching certain confirmation points. This screen
allows the parameters of the audio to be configured. If a particular message item is
checked the main display unit will generate an alarm at the time of event.
LX90xx system Version 4.0 February 2014
Page 56 of 151
Frequency and Periods define the length and pitch of alarm. Press DEMO button to play
alarm sound. Change volume to define loudness of alarm.
Volume level (loudness) can be also set with volume rotary knob, when alarm is
being played
LX90xx system Version 4.0 February 2014
Page 57 of 151
6.1.8 Observation Zones
This menu defines the default observation zone geometry. The following items can be
chosen: start zone, turn point zone, finish zone and templates.
Each type of observation zone is defined with two angles, two radii and mean bearing
(Angle12). These parameters enable the creation of any known zone geometry separately
for start, turn point and finish.
All stored tasks will match this “global” setting except those where the zone was modified in
the task edit menu (see Chapter 6.7.1).
Using parameters in the zone dialogue it is possible to describe all types of observation
zones. Angle12 defines the orientation of the observation zone. Available values for
Direction are:
• Symmetric: This is the most common selection for turn point.
• Fixed: This is mostly used for assigned areas.
• Next: will orient the observation zone in direction of the outgoing leg. This is usually
used for start.
• Prev: will orient the zone in direction of the incoming leg and is usually used for the
finish.
• Start: orientates the sector always towards the start.
If the Line checkbox is checked the sector will become a line type of observation zone. The
Radius 1 parameter describes half of width of line length. Use the PAGE selector knob to
LX90xx system Version 4.0 February 2014
Page 58 of 151
increase the radius by 0.1 of the selected distance units and the ZOOM selector knob to
increase the radius by 5.
If Line is not checked the Angle1 parameter will define the basic shape of the observation
zone. A value of 180° means that the zone is a cylinder and 45° is the classical FAI sector.
Rotate the PAGE selector knob to increase the angle by 0.5° or use the ZOOM selector knob
to choose values 22.5°, 45°, 90° or 180°.
Angle2 and Radius2 are used for more complex observation zone setups.
When changing observation zone parameters the screen is automatically updated to display
the new zone.
Check the AAT checkbox, if you want to make the selected zone an assigned area. The
AAT checkbox will be automatically checked when Radius1 is greater than 10 km.
By default navigation to task points will be automatically advanced; uncheck Auto next if
you do not want to change over to next point when reaching selected point. This option will
be automatically unchecked when Radius1 is greater than 10 km.
Use Template if you wish to modify start, point and finish zones at same time.
Available templates are:
• 500 m cylinders are used for start, points and finish.
• FAI sectors, 90° and 3 km long sector is use in start, turn point and finish.
• 500m and start line. The 500 m cylinder is used for turn points. A 1 km long line is
used for start and finish.
• FAI and start line. 90° and 3 km long sector is used for turn points. A 1 km long line is
used for start and finish.
LX90xx system Version 4.0 February 2014
Page 59 of 151
6.1.9 Optimization
During flight the system optimises the flown path according to OLC or FAI rules. Use this
dialogue to change the way instrument performs this optimisation.
Number of points defines the type of optimisation. Use five for OLC optimisation. Use the
value three for FAI free flight optimisation.
Optimisation will not take into account the 10 km distance between turn points
which is required by FAI rules.
The FAI triangle group defines the rules for FAI triangles and these rules can bend a little if
you do not want to fly marginal triangles.
Check Reset optimization on engine run to reset optimization counter each time engine
is started.
6.1.10 Warnings
There are four types of warnings available. Airspace warnings are shown when approaching
a particular airspace zone. Altitude warnings are shown when approaching to a defined
altitude, Flarm warnings are triggered when conflicting traffic is in the vicinity and Time
Alarms are raised at defined time interval to remind pilot to do specific task.
Use this dialogue to setup the behaviour of warnings.
LX90xx system Version 4.0 February 2014
Page 60 of 151
6.1.10.1 Airspace Warnings
Airspace warnings are the most complex ones. An airspace warning is activated by two
triggers; First warning (orange) will be given when a projected position of flight for period,
which is defined in the Time item, is computed to cross an airspace zone.
Second warning (red) will be raised when a projected position of flight is computed to cross
airspace zone and the glider is already in the buffer zone in the vertical or horizontal
directions. Buffer zones are defined in the Horz.buffer and Vert.buffer items. Default
values are 1 km for horizontal buffer and 100 m for vertical buffer.
The first warning (orange) will also be given when you enter an airspace zone buffer but the
projected flight is computed to cross it.
An Airspace warning will be raised in all modes and dialogues. A warning for an alarmed
zone can be dismissed for a whole day, some minutes or just quit. Quit means that the
message will disappear. Use Dismiss for spin to define dismiss time in minutes. This time
will be shown in the lower-middle button after which the warning will be raised again.
However an alarmed zone will still be filled with transparent red colour and outlined with a
thick line and also the distance to the nearest point of the airspace zone will be shown.
To prevent dismissing by mistake check the Confirm dismiss checkbox and you will be
always prompted to confirm dismiss for a particular airspace zone.
The RESET button will reset the status for all airspace zones.
LX90xx system Version 4.0 February 2014
Page 61 of 151
6.1.10.2 Altitude Warning
Altitude warnings will be enabled if Show warning is checked. Altitude is given in MSL.
Projection is calculated based on the 20 second average vertical speed and time which is
defined in the Time item.
If the projected altitude is greater than the set altitude, an altitude warning will be raised.
Altitude warnings will be raised in all modes and dialogues just as for airspace warnings.
Altitude warnings can be dismissed for 1 minute, 5 minutes or disabled.
LX90xx system Version 4.0 February 2014
Page 62 of 151
6.1.10.3 Flarm Warnings
Flarm warnings will be raised only when system is receiving FLARM data from internal or
external FLARM module. Using this dialogue the user can define which warnings will be
shown and how they are going to be shown. There are three types of warnings:
• Traffic warnings will be raised once a new aircraft is detected by FLARM.
• Collisions will be shown every time a collision risk with an aircraft occurred.
• Obstacles warnings will be displayed when a collision with a ground obstacle is
predicted.
If the voice option is installed it is also possible to hear the horizontal and vertical situation
to the current object. Uncheck appropriate items if you want to disable this part of the
message. You can also define the way direction to the Flarm object will be presented.
There are three options:
• Relative bearing: In this option direction will be given relative to the glider’s nose
direction (e.g.
Traffic 3’ o clock
, which means traffic, is on your right side).
• True bearing: Direction is give with absolute direction (e.g.
Traffic from 330°
)
• Relative/True bearing is a combination of both methods. Relative bearings will be
given when flying straight and true bearings will be given when thermaling.
• Graphical presentation. When this item is check, also a graphical presentation of
FLARM will be shown, when Flarm warning is displayed.
Picture above shows typical Flarm warning with graphical presentation and relative bearing
of object. Press CLOSE to dismiss warning, CIRC.OFF to dismiss for time of circling and 1min
to dismiss all Flarm warnings for one minute.

6.1.12 Hardware*
Use this menu to define hardware properties such as total energy compensation, vario
indicators layout, compass calibration, FLARM module settings, AHRS settings, NMEA output
and data which will be exchanged between the rear and front display units. Some items
may be greyed out when the selected option is not available.
6.1.12.1 Vario unit settings – TE compensation*
All settings in this menu are related to the glider.
6.1.12.1.1 TE compensation - Digital Total Energy Compensation
There are two ways by which the vertical speed can be corrected for total energy:
• digital TE compensation based on speed changes with time
• Pneumatic compensation with a total energy probe.
TE (Pst)
Vario unit
Digital TE compenstaion
Compensation with TEprobe
LX90xx system Version 4.0 February 2014
Page 65 of 151
If the digital TE option has been used TE compensation should be set to 100%.
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 tube has been connected TE compensation should be set to 0%. The
quality of the TE compensation depends entirely on the location, size and
dimension of the TE tube. The installation must be leak-proof.
The digital 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.
Digital 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 digital TE compensation the most likely cause is the glider's static source. The
static source can be checked by plumbing the pneumatic tubes for digital TE compensation
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 digital TE compensation. The use of a dedicated and accurate finmounted Pitot/static source such as a Prandtl tube might help.
6.1.12.1.2 SC Switch
The vario unit has an input for an external speed command switch which is wired to the
vario unit cable set. 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 switch to TASTER and
connecting a push button to the input; each key press will toggle between SC and Vario
(mandatory setting for LX Remote).
6.1.12.1.3 Temperature Offset
The system is supplied with an external outside air temperature (OAT) sensor. With the
offset setting it will correct static errors of temperature measurement.
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.
LX90xx system Version 4.0 February 2014
Page 66 of 151
This input wire i
s set open (not grounded) as a factory default on delivery.
6.1.12.1.4 Airspeed Offset
Some gliders are having quite big difference between calibrated airspeed and indicated
because of imperfect static ports (e.g.: Cirrus Standard). As airspeed effects wind
calculation. It is possible to define an airspeed offset to improve wind calculation.
Vario indicator will ignore this setting and shows not corrected airspeed.
6.1.12.1.5 Digital inputs
V9 or V5 variometers are having four programmable digital inputs. They are labelled with
IN1, IN2, IN3 and IN4 on V5/V9 cable-set. See chapter 4.5.3 for more details on vario unit
wiring diagram. In current version digital input can represent the state of following actions:
• Gear down and lock
• Airbrakes open
• Water ballast open
Digital input shall be wired via switch to ground and it shall open or close, when selected
action is performed. A green light will light.
If necessary, check Invert check box, to reverse the operation of digital input.
Once digital inputs are connected the system will warn pilot, if airbrakes are open on takeoff and when gear is not locked prior to landing.
6.1.12.2 Vario Indicator Setup*
The vario indicator is always part of the vario unit. However an unlimited number of
secondary vario indicators can be connected to the system using the RS485 system bus.
There are three different types of vario indicators; V5 vario indicator, which is standard
part of V5/V9 variometer, V80 vario indicator and old LCD or USB-D vario indicator.
LCD vario indicator and USB-D type of indicator are setup through menu LCD Indicator,
whereas others, more modern vario indicators, are having its own menu item identified with
serial number.
LXNAV is highly recommending upgrading old LCD or USB-D type of vario unit to
latest technology vario unit. Please contact local dealer or LXNAV for more
details.

6.1.12.6 Flarm*
On the Flarm setup page, information about built in or external Flarm are visible.
Information like serial number, selected frequency, firmware version and database versions
are shown.
EXTERNAL FLARM
If Flarm module is built in user can select operation mode. There are three different
operational modes available:
• Power OFF - Flarm unit is switched off.
• Power ON - Flarm unit is switched on.
• Privacy ON - Flarm unit works in stealth mode. Other Flarm units will not receive
altitude and vario information concerning your glider. For collision warnings this mode
has no influence.
If there is no Flarm module built into the main display unit, then instead of operation mode
combo box, baud rate selection will be displayed
Freq shows selected frequency depending on the continent, where system is located.
Port defines serial interface through which Flarm data are being received. Use Ext. (PC)
port when you want to receive externally connected Flarm on PC port. See chapter XXXX
Device ID shows the Flarm unique ID, which is transmitted to other FLARMs.
Competition mode is intended only for competitions. If this mode is enabled the pilot will
not be able to see any Flarm data on the navigational screens. The competition mode
status is recorded in the IGC file and can be checked during scoring.
If you are flying in a competition it is sufficient to turn on Competition mode.
However if you do not want other aircraft to see you, you should switch mode to
Privacy ON.
Reduce warnings will significantly reduce Flarm warnings. Use this option if you are flying
in gaggles or areas with high density of other aircraft.
We recommend you sign in at FLARMNET.org. This is free of charge. Registering
with FLARMNET allows others to see you not only with Device ID but also with
your contest number and name. Refer to Chapter 6.5.6.8.
Send declaration check box is available only when external Flarm is connected. Check this
option, if you want that task declaration is automatically transferred to Flarm.

6.1.12.8 Rear Seat or Front Seat
In a two-seat configuration with the rear seat device it is possible to transfer selected data
between the front and rear seat device. Use this menu to define which data will be
automatically received from the other device.
Data are divided into two groups; flight parameters and navigational data. If a specific
value is checked this value will be automatically received from the other device.
Check MacCready, Ballast or Bugs to receive current MacCready value, current ballast
setting or bugs from other device.
If the Waypoint checkbox is checked a new waypoint target will be automatically assigned
when the user changes the waypoint target on other device. The message
“Waypoint target
received”
will be displayed on the screen and you will be navigating to the same waypoint as
other device. Please note that it is not necessary to have this waypoint in your databases as
the complete waypoint information is transferred.
If the Waypoint checkbox is not checked it is still possible to send a target to the other
device using the SEND action in waypoint mode.
The same applies to the Airport checkbox. The message
“Airport target received”
is
displayed.
If the Task checkbox is checked the task will be synchronised with the other device.
LX90xx system Version 4.0 February 2014
Page 72 of 151
When flying an assigned area task it is worth not having the task checkbox
checked. This will allow one pilot to play with “what if” scenarios. Once a proper
direction is found you can send the task to the other device using the SEND
action in task mode.
6.1.12.9 Remote stick

6.1.13 Polar and Glider*
Use this dialogue to enter glider polar and other properties of glider. As default polar a
standard class glider is selected.
Polars for most modern gliders are already prepared. Press the LIST button and a dialogue
with a list of all available gliders will be shown.
Select the required glider using the PAGE selector knob and press the SELECT button. All
glider data will be copied from the chosen polar. You may quickly check the best glider ratio
and minimum sink rate to see if the polar data matches the glider performance. 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 LX-Polar program to calculate coefficients
a, b and c for a given glider’s polar. The program requires at least 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 system.
You can download program free of charge from www.lxnav.com
Stall speed is used to generate stall warnings which are available only with the LX Voice
module.
Weights must be entered if user enters ballast in kilograms. There are three weights to
enter. Ref.weight corresponds to the Ref.load value and represents the value at which
the polar was measured or recalculated. Reference weight or reference wing load value will
be automatically recalculated based on Wing area property. Max.weight is the maximum
take-off weight allowed for a glider. It is not used in the calculation; it is just a reminder to
LX90xx system Version 4.0 February 2014
Page 76 of 151
the pilot of the maximum take-off weight. Empty weight is weight of the glider without
pilot and ballast. The overload factor is calculated as:

Pilot weight is set in the Flight recorder menu (see Chapter 6.1.2).
For aircraft with flap, it is also recommended to enter flap position labels and speed range
for corresponded flap position. Speed range shall be given for reference wing load or
reference weight.
Once speed range is entered, the system will be able to display requested flap position
based on current wing loading and g-factor.
6.1.14 Profiles and Pilots
All settings and navigational page layouts are stored in a profile. Profiles can be used in
different ways:
• For club operation or multiple pilots sharing the same glider. Each pilot can have his
personal profile.
• When the user is flying a glider which can have a different wing spans. In this situation
the pilot has two profiles, one for each configuration.
• When a pilot is flying in several different locations. A separate profile for each location
can be created (examples: France, Spain, Namibia, WGC2014).
Profile consists of two parts:
• Navigational page layout defines which navboxes and symbols are visible on
navigational page. It defines colour of navboxes, font sizes and colours, how many
navigational pages are visible and which modes are enabled. Navigation page layout
can be setup with LX Styler or on device itself (See chapter 7).
• Device settings includes glider polar, selected databases, selected airspace and
waypoints file, map colours, vario indicator settings and flight computer properties.
Device settings can be modified on device itself through setup menu (See
chapter 6.1) or with LX Styler.
An active profile is selected when the system is powered on (see Chapter 8.1.2).
Use this dialogue to add a new profile, delete a profile, load/save a profile, copy device
settings, change name for an existing profile and to activate a profile. The active profile is
the profile which is currently being used. Select a profile using PAGE selector knob. Press
TO USB or TO SD for the profile will be stored to a USB stick or SD card. A profile is stored
LX90xx system Version 4.0 February 2014
Page 77 of 151
to a file with the .lxprofile extension. Press the LOAD button to load a profile from a SD
card or USB stick. A profile will be copied to the main display internal storage. Press the
EDIT button to edit the profile name.
A profile can also be locked. This option is very useful for club operation where one does
not want a global club profile to be changed. When a profile is locked all settings will be
read-only. Press LOCK button to lock/unlock profile. When a profile is locked am message
(locked) will be written below the profile name. Press ACTIVE to make selected profile as
active one.
When a profile file from USB or SD card is selected, it will be available only, if SD
card or USB stick is inserted in main display unit.
Selecting profiles on SD card or USB allows you to create portable profiles, which
can be transferred from one device to another device.
A profile file can be opened and manipulated with the LXStyler program. LXStyler is a
special program designed to customise layout navigational pages. It can be downloaded
free of charge from our web pages www.lxnav.com. For more information about LXStyler
please refer to the LXStyler manual.

Using the PAGE selector knob you can scroll through the pages. There are several
navigational pages available.
Navigational pages can be customised using LXStyler. The description below
applies to the default navigational pages.
6.5.1 Initial Navigation Page
In the top row the GPS status is shown. Green colour represents GPS 3D, yellow colour
means GPS 2D and red colour is GPS bad. The number of coloured bars indicates the
number of visible satellites. Each bar represents two satellites.
Local time shows the local time. You can set a different time zone in the Units dialogue
(see Chapter 6.1.11).
The battery symbol indicates status of the battery. When the battery is very low the symbol
will turn red and also the Low battery warning will be displayed.
North direction is pointing to true north. This is important if map orientation is not north up
at the top.
The airplane symbol in the middle of the screen is showing current position. The grey line
indicates our current ground track and the magenta line is connecting the airplane position
with selected goal. When we are below the glide-path to current goal a green and a yellow

rectangle will be displayed on the magenta line. The green rectangle represents the
position from where you will achieve the final glide with current altitude and current
MacCready setting. The yellow rectangle represents the position from where you will
achieve the final glide with current altitude and MacCready zero.
The relative bearing (near the top) gives advice on which direction and how much to turn in
order to fly towards the selected target. In the above example we should turn right 21°.
In the lower left corner of screen a wind symbol is displayed. The arrow indicates the
wind direction relative to the map orientation. Wind direction and wind speed are
numerically presented below the arrow.
Zoom scale is displayed in bottom right corner of screen. A distance of drawn zoom symbol
is plotted above the scale. If there is a letter “a” written next to distance scale, it means,
scale of map will automatically adapt to goal.
In the bottom row several items are displayed. Thermal shows the last thermal average,
Brg is the bearing to the selected target, Dis is the distance to the target and Alt is the
current MSL altitude.
The last two numbers (reqE and E) show the required glide ratio to the target. In the
above example the required glide ratio is infinitive and current glide ratio is also infinitive.
The current glide ratio is calculated over the last two minutes of flight.
6.5.1.1 Final Glide Symbol
The final glide symbol is a complex symbol. The bottom number (-682 in the above
example) shows your predicted arrival altitude. Negative numbers indicate that you are
below the glide path and positive numbers indicates you are above the glide path. In the
above example the glider is below the glide path. Chevrons show the position relative to the
required glide path in percent. One arrow means 5% above or below final glide. In the
example more than 25% below glide path is shown.
The middle number is the current MacCready setting. In task mode it is prefixed with the
letter T, A, B, G, S or AG. See chapter 8.2.1 for detailed explanation of this mode.
Sometimes there will be another number above MacCready which is used for arrival over
terrain. If we are on final glide to a selected target but between it and the current position
there is a terrain, which cannot be crossed without more height, then this number will give
you an estimate, how much you have to climb, to pass over the terrain. A red rectangle will
also be shown on the magenta line indicating the point of potential collision.
6.5.1.2 Thermal Assistant
During thermaling the wind symbol will also shows the thermal assistant. The thermal
assistant continuously analyses the thermal whilst circling. The sizes of the dots indicate the
strength of the thermal. Big dots mean stronger lift at that point. On the left or right side
of the circle a small airplane symbol is shown. This airplane indicates your position. A black
dot indicates the thermal maximum. The pilot should extend the circle when the black dot is
about 60° away from glider. This value varies and depends on turn rate of the glider and
type of thermal. All other dots are coloured based on the MacCready setting. Red colour
means values above MacCready, blue values below MacCready and yellow dots represents
lift about the same strength as the MacCready setting.
This colour scheme gives us hints about a thermal at glance. If most of dots are red we
should consider increasing the MacCready value; if most of dots are blue we should consider
decreasing the MacCready setting.

6.5.2 Second Navigation Page
The second page is similar to the first page with additional data shown in the bottom line.
The additional items are the current net vertical speed, current track, ground speed, height
above ground and optimised distance.
6.5.3 Third Navigation Page
The third page is a combination of first navigational page and side view.
Side view is showing lateral view from glider towards selected goal. Terrain below glider is
displayed including glider projected track based on glide ratio in grey colour. Yellow and
magenta lines are showing requested glide ratio to goal based on zero MacCready setting
and current MacCready setting.

6.5.4 Fourth Navigation Page
The fourth navigational page is combination of FLARM radar screen and some additional
altitude data.
The internal pressure sensor altitude is shown as AltIGC. AltInv shows the altitude in
opposite units to those defined in the Units setup. OAT is the outside temperature,
Pot.Temp is the potential temperature and Battery displays the current voltage
The estimated time of arrival and estimated time established are displayed at the bottom
part of page.
6.5.5 Fifth Navigation Page
On this page images of seleced airport are shown, if available.
Also information for the selected airport is shown at the bottom part. This information
includes airport frequency, runway info and description. The estimated time of arrival,
estimated time established and sunrise/sunset times for the selected target are displayed in
last row.

6.5.6.1 Select an Airport
There are four different methods of selecting an airport. They are called filter mode, list
mode, map mode and history mode. You can toggle between these four modes by
pressing the METHOD button several times.
Filter mode
Selecting an airport in filter mode is straightforward. Enter the first letter of the airport
name using the PAGE selector knob. The helper will show the first airport matching this
letter and the next few airports will be displayed in lower part of screen.
Press the CHAR>> button and cursor will move to the second letter. Use the PAGE
selector knob to select the second letter. If you wish to return to the first letter turn the
ZOOM selector knob counter-clockwise.
You will note that part of the airport name is written in a darker colour. Once it becomes
white it means this is the only selection. Pressing GOTO will navigate directly to it. If there
are more than one airports starting with the filtered letters and you press the GOTO button
the cursor will jump to the beginning of the airport name. The PAGE selector knob will
select among the airports. Press GOTO once more and you will navigate to it.
If you do not know the exact name of an airport just select the first letter and
press the GOTO button. Now scroll to the desired airport using the PAGE
selector knob. Press the GOTO button once more and you will navigate to the
selected airport.

6.5.6.2 MacCready, Ballast and Bugs Settings
These are probably the settings pilots use most often during flight. Press the MC/BAL
button. The dialogue for MacCready, ballast and bugs will appear.
Use the PAGE selector knob to modify the MacCready setting. In the middle button there is
a suggestion for the MacCready setting which is based on the last four thermals.
Additionally to the selected MacCready value an overload factor is also shown together with
the calculated glide ratio with corresponding speed.
You will notice that the MacCready value displayed on the final glide symbol is
coloured yellow or red. The coloured value indicates that your MacCready value
is too low corresponding to the current wind and selected target. Increase the
MacCready value.
Pressing the CLOSE button will close the dialogue and return to the navigation page.
Changes will be saved. The dialogue will automatically be closed after 10 seconds if no
action is taken.
Pressing the BAL button will toggle the menu from MacCready setting to Ballast setting.
Ballast is entered in values which are defined in the Units menu (see Chapter 6.1.11). You
can set the load for an empty glider by pressing the Empty button.
Pressing the BUGS button will toggle the menu again from Ballast setting to Bugs setting.
A bug setting is used to set polar degradation due to a dirty wing. The input is in
percentage degradation of glide ratio (5% means glide ratio degradation is 5%). Pressing
CLEAN will set bugs instantly to zero. MC will return to the MacCready screen.
6.5.6.3 Map Settings
Map can be quickly configured using this dialogue. Select map orientation in the orientation
setup.
A map can have north, east, west or south orientation. These orientations are fixed and
are not changed with glider position. Additionally to this orientation there are several more
which will rotate the map as the glider position changes:
• Track up will always have the glider ground track in the up direction.
• Heading up will always have glider heading in the up direction. If the compass module
is available the heading will be taken from the compass otherwise the heading is
calculated from the wind and the ground speed vectors.
• Goal up will have target point in upper part of screen.
• Trk/north up is a combination of Track up and north up orientation. During circling
orientation will be north up otherwise Track up.
LX90xx system Version 4.0 February 2014

• Hdg/north up is a combination of heading up and north up orientation. During
circling orientation will be north up otherwise Heading up.
If Zoom to target is checked the zoom will be automatically adjusted so that the target
point is always visible. Maximum zoom is 200 km and minimum zoom is 1 km. The check
boxes will turn on or off the following items:
• Map – complete map is turned on/off.
• Terrain – only terrain is turned on/off.
• Raster – scanned maps is turned on/off
• Airspace – toggle airspace display on/off.
• Wpts – waypoints drawing is turned on/off.
• Flarm – Flarm radar display is turned on/off.
• Path – flown path is switched on/off.
• Cur.trk – current track vector.
• Opt.dis. – optimised distance.
• Opt.tri. – optimised triangle.
• FAI area – FAI triangle assistant is turned on/off.
A Flarm object may also be hidden because competition mode is on or privacy
mode is on. Please check these settings, if FLARM objects are not visible, even if
the item is checked.
It is possible to store map settings for future use. There are two memory locations MEM 1
and MEM 2 for two different memory settings.
LX90xx system Version 4.0 February 2014
Page 99 of 151
Press button MEM 1 for a long time. A message
“Options stored to memory (1)”
will be
displayed and the settings are stored. Change the settings a little bit. Press button MEM 2
for long time. A message
“Options stored to memory (2)”
will be displayed and the settings
are stored to memory location 2. Now short pressing of MEM 1 will invoke the saved
settings from memory 1.
6.5.6.4 Wind
The main display unit constantly calculates winds using four different methods. Speed
difference method is used during circling and is taking into account ground speed
difference in a single circle. Position drift is calculating wind based on position drift during
circling. A minimum of three circles must be completed to obtain the first wind
measurements. The third method is combination, which takes into account also airspeed
received from the vario unit.
If the compass module is available wind is also estimated using the wind triangle.
Calculated wind is stored in layers. Layer height is 300 m or 1000 ft and cannot be modified
by the user.
The wind profile is shown on the left side of the dialogue. Yellow coloured altitude indicates
our current MSL altitude. Using the ZOOM selector knob you can scroll up and down
through the wind layers.
Use the EDIT button to manually enter wind data. If a new wind direction is entered all
wind directions in range from start altitude to end altitude will be modified. The same
procedure is used for wind speed.
LX90xx system Version 4.0 February 2014
Page 100 of 151
The user can also disable or enable a particular wind method. It is recommended to have
all methods enabled.
Once the wind is modified to suit your needs press the OK button to accept the wind values.
The dialogue will exit automatically.
If the CANCEL button is pressed the wind dialogue will be closed without applying the
changed values.
6.5.6.5 Airspace
The Airspace dialogue shows a list of airspace zones in the vicinity of your position. Vertical
and horizontal distances are calculated to all airspace zones in the list.
The VIEW button toggles the list views. When the STATUS button is pressed the status of
the selected airspace zone will toggle between OFF always, OFF today, OFF hh:mm and
enabled.
If the EDIT button is pressed a new dialogue will open where you can modify properties for
the selected zone. Refer to Chapter 6.1.5.3 for more details.
When a zone is alarmed the distance will be coloured orange.
6.5.6.6 Mark
If you press the MARK button a new waypoint will be created with the current latitude and
longitude and elevation based on the terrain database. The waypoint name is generated
from the current date and time separated by the minus character and preceded by an
underscore.
