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.

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.
Page 19
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

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
Page 23
LX9000 Version 2.6 September 2011
Page 23 of 130
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).

Page 30 of 130
Multiple files can be selected. All checked files will be shown on the graphics page and used in the near mode calculation, if the way point is of the proper type (airport or outlanding place). However, only one file can be the active file. The active file is used for task creation. Press the ACTIVE button to mark the selected file as active. Press the DELETE button to remove the selected file from the LX9000. Press the SAVE button to save way points to the SD Card or USB stick. The save dialogue will be opened.
Change the filename if required. Press TO USB for saving to the USB stick or press TO SD for saving to the SD card. When the compatibility mode flag is checked the file will be saved in DA4 format, which can be used with older LX devices (LX20, Colibri, LX5000, and LX7000).
CUP and DA4 also stores tasks. Tasks will also be uploaded to the LX9000. This feature is very useful, if you wish to prepare tasks on a computer using SeeYou or a similar program. You can subsequently easily select a task via the Task->Edit­>Load option. See Chapter 5.7.6 for more details.
5.1.5.5 Managing Airports
Select the Airports menu item and press the SELECT button. A list of all available airport databases will be shown. Only distributed airport databases are shown in this menu; the
Page 31
LX9000 Version 2.6 September 2011
Page 31 of 130
user cannot modify contents of a database within the LX9000. If an error is suspected in our database please notify us. If you wish to add additional airports to the LX9000 an ordinary way point file should be created and uploaded as a way point file or use the LXe program to modify the airport database.
5.1.5.6 Managing Airports Using the LXe Program
With LXe program version 3.4 or higher it is possible to edit airport data. A new feature, which applies only to the LX9000, is that each airport entry has a field called “description” in which comments or notes of up to 250 characters can be added. Modified airport data can readily be exported to the LX9000 as a (asapt) file and imported to the LX9000 using the standard procedure for database updates (see Chapter 5.1.5.2). User modified databases will be assigned as “user modified” with a version of the database and date of export (modification) executed using LXe. The picture below shows airports that have not been modified (as distributed in initial delivery):
The next picture shows that the European airports database has been modified by the user:
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 .

5.1.5.7 Managing Flights
Select the Flights menu item and press the SELECT button. A list of all stored flights will be shown. The LX9000 is capable of storing more than 1000 hours of flight logs.
If a SD card or USB stick is inserted into the LX9000, flights can be copied to it when the corresponded button is pressed. Flights can be removed from the LX9000 using the
DELETE button.
5.1.5.8 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 to the LX Navigation HDR file.
On the screen pilot, glider and task information are shown. Press the SAVE button to save the declaration onto a SD card or USB stick. Press the LOAD button for loading.
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 5.1.13) 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 5.1.8) and the
Page 33
LX9000 Version 2.6 September 2011
Page 33 of 130
elevation will be defined by the digital ele
vation model built into the instrument.
5.1.5.9 Formatting a SD Card
Use this option if the LX9000 cannot read your card. The LX9000 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 with the LX9000; the LX9000 can do this for you.
Formatting a SD Card will erase the entire contents of the SD card.
5.1.6 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.

5.1.6.1 Terrain and Map
The LX9000 is pre-loaded with terrain for the entire world. The database includes: elevation contour lines, water bodies, roads, highways, railways, big cites and a digital elevation model. The database is derived from the VMAP0 free database and some data may be obsolete. 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 color item. Use the lower-left knob to modify the colour and the lower-right knob to modify the style. Terrain can be rendered in three different levels. A higher level means more details. The LX9000 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. 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.

5.1.6.2 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.
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 item specifies airspace zone colour. You can also modify transparency of the selected type. Turn the lower-left knob to change the transparency value. 100% means completely transparent and only the airspace zone outline will be shown. 0% means completely solid (not recommended). 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. Press the DEFAULT button to reset these settings back to default.
5.1.6.3 Way Points and Airports The way point and airport look and feel is defined in this dialogue. Check the show
waypoints item to enable way points and airports display in navigational pages. If this item
is unchecked no way points will be displayed.
Page 36
LX9000 Version 2.6 September 2011
Page 36 of 130
The Max.visible item defines how long way point labels and detailed symbols are shown. If the maximum number of way points on the current screen is more than the defined value only small blue dots will be shown for way points 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 lower-left knob will change the font colour. Way point labels can be setup to give even more detail. Label details can be defined for each individual way point 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 way point is within range with the current MacCready settings and with a yellow background when way point is within reach with MacCready setting zero. No background is shown if the way point is not reachable. The label is selected from following options:
Name: way point name is shown. The name length item controls how the name is
displayed.
Code: will display the ICAO code or short name.
Elevation: shows way point 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.
5.1.6.4 Glider and Track
The LX9000 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 maximum recommended length is 60 minutes. The path can be coloured using:
Page 37
LX9000 Version 2.6 September 2011
Page 37 of 130
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.
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 and therefore not enough altitude to reach the target with the current glider settings. Press the
DEFAULT button to reset these settings back to default.
5.1.6.5 Optimization
The LX9000 calculates the optimised flown distance according to OLC or FAI rules in real­time during flight (see Chapter 5.1.9). 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 Color item to change the colour of the FAI area. Use the lower-left 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.

LX9000 Version 2.6 September 2011
Page 38 of 130
5.1.6.6 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 lower-left 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.
5.1.6.7 Flarm
LX9000 devices can be equipped with the FLARM module. If your instrument 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 5.1.12.3.
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.
Page 39
LX9000 Version 2.6 September 2011
Page 39 of 130
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. If the show labels item is checked aircraft 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 color item. Use the lower-left knob to modify colour and the lower-right 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. To enable paths check the Show paths item.

5.1.7 Sounds*
In the Sounds setup page audio settings for the vario unit, voice settings for the LX voice module and alarms settings for the vario unit can be modified.
5.1.7.1 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.
Page 41
LX9000 Version 2.6 September 2011
Page 41 of 130
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).
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.

5.1.7.2 Voice*
Voice module is part of V5 variometer. In past the LX Voice Module used to ba an LX system bus participant and receives data and power via the bus. The voice module is 100% controlled through the LX8000 via the settings described in this menu.
In the Voice settings menu volume level (loudness) of the voice module and mixing level between voice and vario sound can be adjusted. In the Messages window each item can be set separately. Only checked items will be posted to the voice module.
If voice module is integral part of V5 variometer, volume level (loudness) can be also set with volume rotary knob, when messages are being played
5.1.7.3 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 LX8000 will generate an alarm at the time of event.

5.1.8 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 tasks stored in the LX9000 will match this “global” setting except those where the zone was modified in the task edit menu (see Chapter 5.7.1).
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: which is the most common selection for turn point.
Fixed: which 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 lower-right knob to increase the radius by 0.1 of the selected distance units and the lower-left knob to increase the radius by 5.
Page 44
LX9000 Version 2.6 September 2011
Page 44 of 130
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 lower-right knob to increase the angle by 0.5° or use the lower-left 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.

5.1.9 Optimization
During flight the LX9000 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. It will also take into account reduced distances for the last two legs. 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.
5.1.10 Warnings
There are three types of warnings available. Airspace warnings are shown when approaching a particular airspace zone. Altitude warnings are shown when approaching to a defined altitude and Flarm warnings are triggered when conflicting traffic is in the vicinity.
Use this dialogue to setup the behaviour of warnings.
Page 46
LX9000 Version 2.6 September 2011
Page 46 of 130
5.1.10.1 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.

5.1.10.2 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.

5.1.10.3 Flarm Warnings
Flarm warnings will be raised only when a FLARM module is built into the LX9000. Using this dialogue the user can define which data will be presented by the LX voice module.
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.
5.1.11 Units

5.1.12.1 Vario Settings*
All settings in this menu are related to the glider.
5.1.12.1.1 Electronic Total Energy Compensation
The LX9000 offers two methods of vario TE compensation:
TE pitot tube
Electronic TE compensation
It is important to note that the method of TE compensation is set up when the instrument is installed by virtue of the pneumatic connections made to the TE and static ports. Changing the compensation type in the setup screen below WILL NOT change the method of compensation - the pneumatic plumbing has to be changed first (see Chapter 6).
If the TE pitot tube has been connected TE compensation should be set to 0%. There is no further adjustment of TE compensation possible. Quality of the TE tube is the one and only factor.
If the electronic TE option has been installed TE compensation should be set to 100%.
The electronic TE compensation can be fine tuned during flight using the following procedure. It is essential that this is only done in smooth air; it is not possible to tune the TE accurately in turbulent air. Set TE compensation to 100% and TE filter to default. 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. The TE filter is the compensation delay and is not used on V5 variometer. Larger numbers will increase the delay and vice versa. During the first test is recommended to use TE filter
4. Electronic TE compensation is only effective when the pitot tube and static sources are co­located and the pneumatic lines to the instrument are approximately the same length. The
Page 51
LX9000 Version 2.6 September 2011
Page 51 of 130
best sensor to use is the combined pitot/static Prandtl tube. If problems are experienced with the electronic TE compensation the most likely cause is the glider's static source. The static source can be checked by plumbing the pneumatic tubes for electronic compensation and then setting the TE: to 0%. In still air accelerate to approximately 160 km/h and slowly reduce the speed. Observe the vario indicator. If the static source is good the vario should immediately start to move to show a climb. If the needle firstly shows increased sink and then moves to a climb, the static source of the glider is unsuitable and there is no way to provide successful TE compensation electronically. The use of a dedicated and accurate fin­mounted pitot/static source such as a Prandtl tube might help.
5.1.12.1.2 SC Switch
The LX9000 has an input for an external speed command switch which is wired to the vario unit. Using the external switch it is possible to switch between SC and Vario manually. Setting the SC switch to ON means that closing the switch will cause the instrument to enter SC mode and setting SC switch to OFF means that closing the switch will select Vario mode. There is a third option by setting SC INPUT to TASTER and connecting a push button to the input; each key press will toggle between SC and Vario (mandatory setting for LX Remote).
5.1.12.1.3 Temperature Offset
The LX9000 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. This input wire is set open (not grounded) as a factory default on delivery.
5.1.12.1.4 Altitude Source
The LX9000 has two pressure altitude sensors. One is built into the main digital 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.
5.1.12.2 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; LCD vario indicator with monochrome LCD, USB-D type of vario indicator or V5 vario indicator. LCD vario indicator and USB-D type of indicator are setup through menus Indicator 1 – Indicator 4, whereas V5 vario indicator is identified by its serial number and is setup through menu Indicator Sn#XXXXX.
All new instruments are delivered with V5 vario indicator.
5.1.12.2.1 V5 Vario indicator V5 Vario indicator is having mechanical needle and colour screen with 320x240 pixels
resolution on which user selectable data are displayed. Each V5 vario indicator is identified by a serial number, which is also displayed on hardware menu. Therefore literally unlimited number of vario indicators can be connected to RS485 bus and each of them can be setup separately.

Depending on which region/continent you are flying in, set the correct frequency band. 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 LX9000 map. 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 reduced 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 5.5.4.7.
5.1.12.4 Compass*
When a compass is connected to the LX9000 calibration is crucial for correct operation. Refer to Chapter 10.2 for details about installation of the compass and its calibration.

5.1.12.5 Rear Seat or Front Seat
In a two-seat configuration with the LX9000D it is possible to transfer selected data between the front and rear seat devices. 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 way point target will be automatically assigned when the user changes the way point target on other device. The message
“Waypoint
target received”
will be displayed on the screen and you will be navigating to the same way point as other device. Please note that it is not necessary to have this way point in your databases as the complete way point 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 way point 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.
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.

5.1.12.6 AHRS
When AHRS device is connected to the system, this menu is used to calibrate AHRS for installation error.
Place you glider in levelled position and press LEVEL button. You can also modify pitch only, if you rotate PAGE UP/DOWN rotary knob.
5.1.12.7 NMEA Output*
The LX9000 is capable of outputting position data sentences in NMEA format for use by other devices.
Data is divided into three groups:
GPS data will output all GPS-related data such as time, longitude and altitude.
LX9000 data will output all variometer-related data such as vario, MacCready and
ballast.
Flarm data will output all Flarm-related data.
The NMEA baud rate will be always 19200 bps; any other settings are ignored.
5.1.12.8 Engine Noise*
The current engine noise level is shown as a progress bar. Use this menu to display your current engine noise.

5.1.13 Polar and Glider*
Use this dialogue to enter glider polar and other glider properties. 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.
Page 60
LX9000 Version 2.6 September 2011
Page 60 of 130
Select the required glider using the lower-right 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 LXe program (Tools->Polar) to calculate coefficients a, b and c for a given glider’s polar. The program requires three sink points entered at selected speeds (e.g.: 100 km/h, 130 km/h, and 150 km/h). The program will calculate the values of a, b and c, which should be noted and entered into the LX9000. 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. Min.weight corresponds to the min.load value and represents the value at which the polar was measured or recalculated. Max.weight is the maximum takeoff weight allowed for a glider. It is not used in the calculation; it is just a reminder to the pilot of the maximum takeoff 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 5.1.2).
5.1.14 Profiles and Pilots
All LX9000 settings and navigational page look and feel 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, WGC2008).
An active profile is selected when LX9000 is powered on (see Chapter 7.1.2).
Page 61
LX9000 Version 2.6 September 2011
Page 61 of 130
Use this dialogue to add a new profile, delete a profile, load/save a profile, change name for an existing profile and to activate a profile. The active profile is the profile which is currently being used. Press TO USB or TO SD for the profile will be stored to a USB stick or SD card. A profile is stored 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 LX9000. 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. A profile file can be opened and manipulated with the LXStyler program. LXStyler is a special program designed to customise the look and feel of navigational pages. It can be downloaded free of charge from our web pages www.lxnav.com.

5.4 Statistics Mode
The Statistics mode operates in two different ways. During flight statistical data for the current flight is shown whilst on the ground the logbook for all stored flights is displayed.
5.4.1 Logbook
If a SD card or USB stick is inserted into the LX9000 the user can copy a selected flight to it. Select the desired flight using the lower-right knob and then press the appropriate button.
A flight is automatically copied to the SD card and/or USB stick if it has been inserted into the LX9000 when the message
“Calculating security”
is displayed.
This message appears when landing conditions are met.
You can also delete a flight using the Files and Transfer menu (see Chapter 5.1.5.7).
5.4.2 Statistics During Flight
Using the lower-right knob the user can change the statistics page. There are three pages available:
Flight statistics displays data for whole flight. Dis.flown is the optimised distance.
XC speed is average speed corrected for altitude difference. Average vario is used in this calculation.
Task statistics displays data for the started task. Distance flown is the distance that
has already been flown on the task.
Page 68
LX9000 Version 2.6 September 2011
Page 68 of 130
The last 60 minutes statistics displays data for the last 60 minutes of flight. If the task
was started then Dis.flown is the distance flown on the task for the last hour otherwise it is the optimised distance. If the task distance is used a remark (On Task) is displayed in the header.

5.5 Airport Mode
Using the lower-right knob you can scroll through the pages. There are four navigational pages available.
Navigational pages can be customised using LXStyler. The description below applies to the default navigational pages.
5.5.1 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 5.1.11). 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 reach aachieve 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 156°. 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. 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 63 and current glide ratio is 44. The current glide ratio is calculated over the last two minutes of flight.
5.5.1.1 Final Glide Symbol
The final glide symbol is a complex symbol. The bottom number (-1313 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 7.2.1 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 terrain which cannot be crossed without more height, then this number will give us an estimate as to how much we 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.
5.5.1.2 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.

5.5.4.2 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 lower-right 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 5.1.11). 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.
5.5.4.3 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.
Hdg/north up is a combination of heading up and north up orientation. During
circling orientation will be north up otherwise Heading up.

Page 77 of 130
are stored to memory location 2. Now short pressing of MEM 1 will invoke the saved settings from memory 1.
5.5.4.4 Wind
The LX9000 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 lower-left 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. 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.
5.5.4.5 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.
Page 78
LX9000 Version 2.6 September 2011
Page 78 of 130
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 5.1.5.3 for more details. When a zone is alarmed the distance will be coloured orange.
5.5.4.6 Mark
If you press the MARK button a new way point will be created with the current latitude and longitude and elevation based on the terrain database. The way point name is generated from the current date and time separated by the minus character and preceded by an underscore.
Way point data can be modified. Refer to Chapter 5.6.1 for more details. Press the OK button to save a marked way point or press CANCEL to exit without saving. Press GOTO button to navigate immediately to selected point.
5.5.4.7 Flarm
Press the Flarm button to view the list of other aircraft received by Flarm. A list with all received aircraft since the last switch on is shown.
Page 79
LX9000 Version 2.6 September 2011
Page 79 of 130
The list is sorted by distance. Select the desired Flarm target and press the GOTO button. You will start navigating to this Flarm position. Instead of Flarm device ID you can also show the competition number for a particular glider. Press EDIT to enter the edit dialogue for the selected Flarm object.
Enter data about the Flarm glider and pilot. The LX9000 is pre-loaded with the FlarmNet database to identify known FLARM Device IDs with plane and pilot data. You can upload the latest FlarmNet database after downloading it from http://www.flarmnet.org. The update procedure is similar to the update procedure for airport databases. See Chapter 5.1.5.2 for more details about updates.
We encourage all users to upload their data to the FlarmNet web site. It is very easy. All you need is to determine your Flarm device ID which you will find in the Hardware->Flarm dialogue (see 10.1.5) and then register at FlarmNet.

5.7 Task Mode
Task navigation mode is used for task manipulation. Navigation in this page is exclusively to the selected turn point of the declared task.
A task can be created only from way points stored in the active way point file. A task can be loaded from tasks stored in the active way point file. A task can also be saved to an active way point file (see Chapter 5.1.5.4 for details how to set an active way point file). A task used for navigation will also be declared in the IGC file.
Task mode has four pages. Use the lower-right knob to switch between pages. These pages are designed to suit needs for racing tasks as well as for assigned area tasks with minimum task time.
The first page is identical to first pages of the airport and way point modes. It shows navigational data to the current turn point. However the final glide indicator always shows the required altitude to complete the task. On the second page additional data is shown:
current netto vertical speed
current track and groundspeed
tDis shows the remaining total task distance.
tskE shows the required glide ratio to task finish.
Page 85
LX9000 Version 2.6 September 2011

The third page is designed for tasks with time limits which are in most cases going to be assigned area tasks. Three new symbols are added:
Tsk.Sp: which is task speed achieved up to this moment.
tReq.Sp: which is the required speed to task completion and is calculated as the
remaining task distance divided by the remaining time.
TRemain: indicates the remaining task time.
The fourth page has no map and shows time values for the task being flown and the elevation of the finish point. In addition outside temperature, potential temperature and battery voltage are shown.
When any of the eight buttons are pressed functions for the buttons are shown. If the selected button is pressed once more the selected action will take place. Press the MORE>> button to see more options. If the remote stick is available the behaviour is slightly different. When the check button is pressed on the remote stick menu will appear instead of the button functions.

5.7.2 Task Creation
Make sure that at least one way point file is loaded into the LX9000 and that it is checked and marked as an active way point file. Refer to Chapter 5.1.5.1 for details on how to upload way point files to the LX9000. Select task time and press the EDIT button. Enter the task time if required. Rotate the lower-right knob to increase time in 15 minute steps and the lower-left knob to increase task time in 1 minute steps. Close the task time edit and rotate the lower-right knob to select the first empty point. Press the EDIT button and enter a turn point name. Entering a point name is very straight­forward. Enter the first letter of the task point name using the lower-right knob. The “Helper” will show the first way point that matches this letter.
Press the CHAR>> button and the cursor will move to the second letter. Use the lower­right knob to select the second letter. If you want to return to the first letter turn the lower­left knob anticlockwise. Repeat this procedure until your desired point is selected. Press the SELECT button to complete this selection. If you do not know exact name of a point just select the first letter and press the SELECT button. Now scroll to the desired point using the lower-right knob. Press the SELECT button once more to complete this selection. The task edit dialogue should now look like the screen below. The letter “S” indicates you entered the start point.
Move the cursor down to the next empty point and repeat the above procedure until the entire task is entered.

5.7.3 Modifying Zones
Now it is time to modify the observation zones. Select a point and press the ZONE button. A new dialogue with the observation zone for the selected point will open.
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 parameters for Direction are:
Symmetric: the most common selection for a turn point.
Fixed: mostly used for assigned areas.
Next: orients the observation zone in direction of the outgoing leg. This is usually used
for start.
Prev: orients the zone in direction of the incoming leg and is usually used for the finish.
Start: orients the sector always towards the start.
If the Line box is checked the sector will become a line type of observation zone. The Radius1 parameter defines half the width of the line length. Use the lower-right knob to
increase the radius by 0.1 of the selected distance units and the lower-left knob to increase the radius by 5 units. 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 classic FAI sector. Rotate the lower-right knob to increase the angle by 0.5° or use the lower-left 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.
Page 89
LX9000 Version 2.6 September 2011
Page 89 of 130
Press the NEXT>> button when you are happy with the changes andto continue with the next observation zone setup.
If the zone is for an assigned area turn point it will be marked with symbol ‘#’ in front of the point name.
5.7.4 Task Options
Press the OPTIONS button. The options dialogue will be opened.
Enter the task description. This is very useful during competitions where you are given more than one task per day. Some hints for names are DAY1-B, Triangle1000km etc. Check Finish is 1000m below start when you are making a badge or record flight. If this option is checked the LX9000 will not navigate you to the finish point elevation, but to the altitude which is going to be 1000m below the start altitude. Check Navigate to nearest point and the LX9000 will navigate you to the nearest point on the start zone or start line and finish zone.
The Navigate to nearest point option is very useful and actually a must if a finish cylinder is used with a significantly large radius. Enabling this option will calculate the final glide to the edge of the cylinder rather than to the centre of the cylinder.
There are also several options in this menu which will help competition pilots to have a less stressful start.
5.7.4.1 Gate Time Gate time is the time when the start gate is going to open. If this value is entered the
instrument will not give you any message about starting a task before the gate time is reached. A notification will be given when the gate is opened.
5.7.4.2 Below Altitude Start Procedure
On some competitions there is a rule that a pilot must be below a defined altitude for a certain amount of time. Enter Below alt. and Below time to use this option. An indication will be given on the final glide symbol. Character “B” will be displayed before the MacCready value which indicates that the final glide is in below altitude mode.
Page 90
LX9000 Version 2.6 September 2011
Page 90 of 130
The lower number shows the difference to the set altitude. Negative values mean altitudes below set altitude. The upper yellow number indicates the number of seconds left to be below the set altitude. Chevrons indicate meters below or above required altitude. Each line represents 10 m. A message
“You were XX seconds below YYYYm!”
is displayed once you
fulfil the conditions.
5.7.4.3 Maximum Start Speed and/or Maximum Start Altitude
A lot of competitions are limiting the start altitude and/or start ground speed. The LX9000 helps pilots to cross the start line at the correct altitude with correct ground speed. Enter Start alt. and/or Start gsp. to use this option. An indication will be shown on the final glide symbol. Character “A” will be displayed before the MacCready value if a start altitude was entered and/or character “G” will be displayed if a start speed was specified.
The lower number indicates at what altitude you will reach start altitude. A negative value indicates you are going to be there below the required start altitude.
Page 91
LX9000 Version 2.6 September 2011
Page 91 of 130
The arrival altitude to start is not based on MacCready, the glider nor the wind settings. It is calculated based on energy difference during flying straight. This will give you a very precise estimate at what altitude you will arrive at the start. Speeding up will result in greater energy loss and the arrival altitude will decrease; slowing down to best glider ratio will decrease energy loss and the arrival altitude will increase.
The upper yellow number shows the current ground speed and the chevrons indicate if you have to slow down or you may speed up. In the picture above we are 445 meters below the glide to start altitude. Our speed is 122 km/h and the chevrons show that we can speed up.
Start speed and start altitude mode is available only if the Navigate to nearest
point is checked.
5.7.5 Saving a Task
Once a task is completed it could be saved to the active way point file. Press SAVE and the message
“Task saved”
will appear on screen.
If the task already exists in the active way point file the message
“Task is already saved!”
is
shown.

Page 92 of 130
5.7.6 Loading a Task
It is possible to load a task from the stored tasks within the active way point file. Select the LOAD action within task mode. A dialogue with a list of all stored tasks will be shown.
Total task distance, task description and task points are shown for each task stored. Select the desired task by rotating the lower-right knob and press LOAD. The task will be loaded into the active task and the task edit dialogue will be opened. It is also possible to delete tasks from the active way point file. Press the DELETE button to delete the selected task. Tasks can be sorted by start point, task distance and task description. Press the SORT button to toggle the sort method.
5.7.7 Moving a Task Point
If at least one observation zone is defined as an assigned area, it is possible to move a point within this area. Moving a point will increase or decrease the total task length. Select the MOVE action within task mode. A dialogue with the current assigned area will be shown.
Page 93
LX9000 Version 2.6 September 2011
Page 93 of 130
In the upper-right corner the remaining task distance, required task speed, remaining task time, delta time and estimated time of arrival are shown. Delta time is the difference between the remaining time and time of arrival. If it is negative you will arrive back home too soon and if it is positive you will arrive too late. Keep in mind that the time of arrival can be calculated using different methods which are found in the QNH and RES setup (see Chapter 5.1.1). A point is moved using the lower two knobs. Press the DIS/BRG or LON/LAT button to toggle between the two methods of moving the point. When the DIS/BRG button is shown the point is moved in the x, y directions. Use the lower-right knob to move the point in the north/south direction or rotate the lower-left knob to move point in east/west direction. If the LON/LAT button is shown the point is moved in the radial and azimuth directions. Radial direction is indicated with red line going through whole sector. Rotate the lower-right knob (page selector) to move the point in the radial direction from the area centre. Use the lower-left knob (zoom) to move the point in the axial direction. If more than one assigned area is set for a task the NEXT>> button is shown in the lower line. Press this button if you wish to move the point into another assigned area.

6 Variometer and Altimeter
All signals from the pneumatic sensors (altitude, speed) are derived from high quality pressure sensors which mean that no flask is necessary. The vario signal is derived from the altitude signal. All signals are temperature and altitude compensated. Mechanical needle and colour display are displaying the vario information as well as many other parameters. The display is user configurable. The variometer can be configured to show:
Range 5, 10 and 2.5 m/s or 10, 20 and 5 kts.
time constants 0.1 s to 5 s, in addition there are 4 settings for electronic processing
for the vario signal.
netto shows the air mass lift and sink.
relative shows the lift or sink that would be achieved if the glider was circling at the
thermaling speed. There are two ways by which the vario indications can be corrected for total energy; electronic TE compensation based on speed changes with time and pneumatic compensation with a TE probe. The quality of the TE compensation depends entirely on the location, size and dimension of the TE tube. The installation must be leak-proof.
If an electronic TE compensation is selected the TE (Pst) port should be connected to a good static pressure source. If pneumatic compensation is selected the TE (Pst) port should be connected to the TE probe.
6.1 Smart Vario Description
The LX system incorporates two configurable electronic filters in the circuitry. The first filter adjusts the time constant and is adjustable between 0.5 and 5 seconds. The 0.5 second setting is the fastest while the 5 second setting provides maximum damping. The second filter, called the Smart Vario, is a dynamic filter and controls the rate at which the vario indicator moves. It behaviour differs depend on variometer type.
6.1.1 Smart vario on V5 vario system
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.
6.1.2 Smart vario on other vario systems
On older models of variometer smart filter value gives us four levels of dynamic damping of the vario. When set to OFF there is no restriction on the rate of movement of the vario indicator other than the setting of the time constant filter. When set to 1 the vario indicator will not move faster than 1 m/s (2 kts) per second, whilst when set to 4 the vario indicator

will not move faster than 4 m/s (8 kts) per second. It should be noted that when set to 4 the vario indicator will move four times faster than when set to 1. Summary: The Smart Vario should not be used in isolation but in conjunction with the setting of the time constant filter. When the Smart Vario is activated the time constant filter may need further adjustment to provide optimum indications.
6.2 Altimeter
The altimeter of the LX9000 is temperature compensated from -20ºC up to + 60ºC. The altimeter is calibrated from 0 to 9000 m (30,000 ft), but indication goes up to 16000 m (52,000 ft).
6.2.1 IGC Barograph Recalibration Procedure
The LX9000 has an additional pressure sensor for altitude recording. To comply with IGC procedures this sensor has no external pneumatic connection. To carry out the barograph calibration procedure it is necessary to remove the instrument from the glider and place it in a vacuum chamber. The procedure is as follows:
Switch the instrument ON and wait some minutes (straight line on the barogram
beginning).
Set the recording interval to 1 second (see Chapter 5.1.2).
Place it in the chamber and carry out a short climb to about 100 m (to start the flight
recorder).
Bring the chamber pressure to exactly 1013.2 hPa.
Decrease the pressure by 1000 m and hold for about 30 seconds.
Continue the procedure to 6000 m.
Increase the pressure in 1000 m steps back to 1013.2 hPa.
After reaching ground wait about 3 minutes and then switch the instrument off.
Leave the instrument off for at least 5 minutes.
Download the last flight and print the barogram using the LXe PC program.
Restore the flight recorder settings.
The barogram will be the last flight in the logbook.
6.3 Speed Command
Speed command flying based on the MacCready theory is a very useful tool to optimise cross-country speed. There are many visual indicators (see LCD Vario). When the instrument changes to speed command mode the audio will change and become a director informing the pilot whether he is flying too fast or too slow. In order to reduce confusion between vario and speed command audio some special features were developed:
Continuous audio signal in + possible (other kinds of signals can be chosen, see
setup).
No audio at correct speed (dead band).

7 Flying With the LX9000
To get the best out of the LX9000 it is important that some preparation is done prior to takeoff. Trying to configure the instrument or set a task while flying is very hazardous especially in a competition. At the least, it could spoil your whole day! Pre-flight preparation will ensure that the flight will be both safe and enjoyable.
7.1 On the Ground
7.1.1 Power on Procedure
Press the power-on button. The LX9000 and the vario unit will turn on and few moments later welcome screen will appear. The first screen shows the version of the boot loader followed by the version of the Linux kernel operating system, then the version of the file system. The boot procedure normally takes 30 seconds. When completed the profile selection dialogue is shown.
It is recommended to switch the unit ON some minutes prior to takeoff to give the GPS receiver time enough to acquire satellites. The flight recorder will also make a takeoff baseline. Longer running on the ground will not reduce flight recorder capacity.
7.1.2 Profile Selection
Turn the lower-right knob to select the desired profile if more then one profile is available. For the selected profile the pilot name, glider type, loaded way point files, loaded airports databases and loaded airspace databases are shown. To learn more about profiles refer to Chapter 5.1.14. Press the SELECT button to confirm selection of the profile. The set elevation dialogue will be shown next.

7.1.3 Set Elevation and QNH
This setting is crucial for final glide calculation: therefore pay careful attention to it.
The instrument will offer elevation from the terrain database based on current latitude and longitude. Elevation will mostly be within few meters from the current elevation. Use the lower-right knob to fine-tune the elevation. If the elevation is unknown and the QNH pressure is known you should NOT press button QNH. Just keep turning the lower-right knob (PAGE selector) and observe the QNH value to adjust it to proper value. The QNH button should be pressed only when airfield elevation and QNH pressure are given. This might happened on some competitions. In all other cases elevation should always match QNH pressure.
The profile selection and Elevation dialogues are not shown if the LX9000 is switched off and on during flying.
7.1.4 Preflight Check
After elevation setup the LX9000 will switch to airport mode. It will take about 30 seconds to draw the map screen for the first time. All way point files and databases are loaded at that time and therefore instrument might react somewhat slowly. It is recommended to check the MacCready, ballast and bugs settings to match the current glider configuration. Press the MC/BAL button. The dialogue for MacCready, Ballast and bugs will appear.

Use the lower-right knob to modify the MacCready setting. Refer to Chapter 5.5.4.2 for more details. It is also highly recommended to check the safety altitude setting. Refer to Chapter 5.1.1 to find out how to define the safety altitude.
7.1.5 Preparing a Task
While it is advisable to prepare the task properly before taking off and thus avoid mistakes made in a haste, all the following actions, preparing, editing, loading and saving, can be done while in the air. But then, the task cannot be declared in the air.
There is only one task. This task will be automatically declared in the IGC file on takeoff. The task can also be modified during flight but any changes will not be written to the IGC file.
There are currently three methods to create a task. Further methods will be available in future releases.
Read way point and task file from SD card and load a saved task.
Load a similar task and modify it.
Enter task manually.
It is very important to check the task prior to takeoff. Check the turning points sequence, distance between points, bearings and total task distance. Visually check the task and observation zone geometry in the map view.
7.1.5.1 Assigned Area Tasks (AAT)
In fact an assigned area task is a speed task where the task distance is not exactly defined. The pilot has limited influence on the task geometry due to larger observation zones (assigned areas). The pilot decides how far he will fly into each individual area to reach best average task speed and not finishing the task earlier than the designated task time. An assigned area task has the same structure as other tasks and all known methods to enter are the same as described. The only differences are larger observation zones having a specific geometry. Use the ZONE button (see chapter 5.7.3) to modify the individual observation zone.

Page 100 of 130
Usually a task sheet with observation zone definitions matching the LX9000 observation zone definition will be given. An example of a task sheet is shown on the previous page. However when an assigned area is defined only with two radials and two radii some calculation must be accomplished.
Let us assume an assigned area defined as: Radial1=30°, Radial2=70°, Min.radius=50 km and Max.radius=200 km To convert this description the following calculation must be performed:
Direction set to FIXED.
Angle12= (Radial2-Radial1)/2+180°=230°. Attention should be paid with northerly
directions.
Angle1= (Radial2- Radial1)/2=20°.
Radius1=Max.radius=200 km.
Radius2=Min.radius=50 km.
7.2 Flying a Task
After takeoff the unit will switch to flying mode. The pilot will notice this because the statistics page will change from logbook view to flight statistics.
7.2.1 Starting a Task
Before starting a task (in task mode) a character “S” will be displayed on the final glide symbol. This indicates that the task has not yet been started. The lower number tells you at what altitude you will start. For more advanced start options such as maximum start speed, maximum altitude and before start altitude see chapter 5.7.4. Once you decide to start the task and glider enters start observation zone, the message
“Inside start zone”
will
be displayed.
You may now leave the start observation zone and fly towards the first turn point. When leaving the start observation zone the message
“Task started”
will be shown.
