2 Basics

2.1 The LX9xx/LX80xx series at a glance

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

 LX8080 model with 2.8” screen and 320x240 pixels resolution,  LX8000 model with 3.5” screen and 320x240 pixels resolution,  LX9050 model with 5.0” screen and 800x480 pixels resolution,  LX9000 model with 5.6” screen and 640x480 pixels resolution,  LX9070 model with 7.0” screen and 800x480 pixels resolution.

Standard part of system is also the V8 vario unit. It is a most modern variometer running on very powerful processor with inertial platform using 3 axis accelerometer, 4 gyroscopes (for inertial vario, AHRS and wind calculation), smooth audio output with audio equalizer and integrated synthesized speech output. The unit communicates with the main display unit over the RS485 system bus. V8 vario features 57 mm diameter (2¼") colour screen and three additional buttons.

Optional vario units are available:

 V80 vario features 80 mm diameter (3”) colour screen and three additional buttons  V9 vario with 57 mm diameter (2¼") indicator with mechanical needle and colour

display for additional data. Optionally additional vario indicators and a wide range of interface devices can be daisychained using the RS485 bus.

2.1.5 Interfaces

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

2.1.6 Internal Options

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

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

Page 12 of 192

Basics Version 6.03, May 2017

2.1.7 External Options

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

The following units can be connected to the main system:

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

The unit installed in the rear seat of the glider is powered and receives all necessary data from the main unit. The communication between both units is exclusively via the RS485 bus system.

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

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

 Electrical Compass Device  Secondary Vario Indicators (I8,I9 or I80 indicator)  Flap sensor  MOP box for jet engines  232 Bridge for radio or transponder  Wi-fi module  External Flarm module

Page 26 of 192

System Description Version 6.03, May 2017

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.

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.

Method 3

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

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

Operating Modes Version 6.03, May 2017

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

altitude, care should be taken when changing the value as an incorrect setting can upset the final glide calculation.

5.1.1.2 Safety Altitude

This setting is the altitude reserve or safety altitude and is the height that the instrument adds to the final glide altitude required so that the glider arrives over the final glide destination at the selected safety altitude. Once the safety altitude has been specified, the pilot has to keep the final glide indicator on 0 to arrive at the safety altitude.

5.1.1.3 Altitude source

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

5.1.1.4 Magnetic Variation

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

5.1.1.5 ETA/ETE Calculation

In changing this value you may choose from four different methods to calculate the estimated time of arrival to the navigational point. Calculation is always divided into straight flight and climb time calculations.

 MacCready uses the Polar data and MacCready setting to calculate speed to fly and

climb rate.

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

calculate speed to fly.

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

distance and Vario statistics for climb rate.

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

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

5.1.1.6 Soaring Start*

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

Page 31 of 192

Operating Modes Version 6.03, May 2017

There is no setup for glider type. Glider type is defined in the Polar and Glider setup (see Chapter 0).

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.

5.1.2 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 5.1.9.5). If the system is used in two-seat aircraft the name of the co-pilot may also be entered.

If a new pilot is entered, upon exiting the dialogue the message

will be asked. Answer YES if you want to quickly add a new profile.

“Do you want to create new

For more information about profiles see Chapter .

User can also enable options log other aircrafts data(Flarm data) and flap position.

Operating Modes Version 6.03, May 2017

5.1.3 Vario Parameters*

This option is used to set the vario parameters.

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. 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.

Page 33 of 192

Operating Modes Version 6.03, May 2017

The external switch wired to the vario unit has absolute priority and will override all other switching methods.

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).

Netto time defines the integration period for the average netto vertical speed in seconds. The default is 20 seconds.

5.1.4 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.

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 Map and Terrain

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.

Operating Modes Version 6.03, May 2017

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.

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.  Flatland2 is setting where in low terrain is white, otherwise normal colours are used.  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  OSM  Himalaya  Relative is a colour scheme related to the current altitude (unreachable area is

coloured from orange to red, reachable area is white coloured)

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.

Following elements are available:

 Water  Road  Highway  Railroad  Town  Track  Airport  Minor Water  Forest  Street  Minor roads

Alternatively, if you’re low on internal space, you can rename “.hglzip” extension of the package to “.zip” and extract it in a folder on a SD/USB. After inserting such

SD/USB into the device your package will be immediately available for selection in Maps dialog and will not require loading the data onto internal memory. WARNING: Using this option you MUST NEVER remove the SD/USB before turning the device OFF.

Check Show wind direction, if you would like to see lines indicating the direction of the wind.

5.1.6.1.1 HGL – high resolution elevation data

HGL – high resolution elevation data is an add-on package which does not come preinstalled on the device. It provides high resolution elevation data for better view of terrain, see images bellow. HGL packages take a lot of space so we limit them to only selected regions.

Left: terrain rendered using normal maps, right: terrain rendered using HGL.

5.1.6.1.1.1 HGL-install procedure

HGL terrain can be downloaded from www.lxnav.com. After downloading selected HGL package you can install it via Setup->Password->insert 89891. Package will be unpacked to internal memory and available for selection in Maps dialog.

5.1.6.1.2 Maps CITv1/CITv2

CITv1: regular maps containing vector and elevation data. Preinstalled on all devices. CITv2: New maps containing vector and elevation data. Supported by firmware version >

5.06 and preinstalled on devices produced from 2014 onwards.

Page 52 of 192

Operating Modes Version 6.03, May 2017

Depending on when your device was manufactured it may already contain the new maps (CITv2). Installed maps can be seen in “SETUP-ABOUT” dialog (after installing version

6.0+).

You will see "Installed maps: CITv1, CITv2 (used)", if you have newer maps installed. If not then it will state "CITv1 (used)".

5.1.6.1.2.1 CITv2-install procedure

If CITv2 is not preinstalled then you will need to verify that enough free space is available on your device before installing CITv2 maps.

Installation on device is as follows:

1. Verify that you have enough available free space on internal memory by going to Setup>Password and enter 00111. Verify that "FreeMem CF" value displayed is at least 3.8 GBytes.

2. Download CIT files from:

https://my.pcloud.com/publink/show?code=kZiiy0ZzEanvinK8pQ0dYferQPHo4Htxu7V

These files will also be automatically verified while being copied to your device. To prevent

discovering a faulty download “on site” you can (optionally) verify downloaded files on your

PC using a tool like HashCheck http://code.kliu.org/hashcheck/

After installing HashCheck you can double click on checksums.md5 file to automatically trigger verification of downloaded CIT files.

Verification of downloaded files with HashCheck tool.

3. Copy downloaded CIT files to USB or SD and use "Safely remove hardware or eject media" (

) before removing the SD or USB from the PC. This step prevents

Operating Modes Version 6.03, May 2017

If you don’t have enough space available and if you wish to have the CITv2, you should contact LXNAV about the HW/memory upgrade.

accidental removal of the media before files are fully written to it. Removal while files are being written would result in corrupted files on the media.

4. Install latest version of the firmware on your device.

5. With SD/USB containing CIT files inserted into your device go to Setup->Password and enter 00112. You will now be asked "Map (CIT) file(s) have been detected on external media. Would you like to copy them to internal memory?" Press "Yes".

Copy procedure will begin and maps will be copied to internal memory. You will see an estimation of time to finish (ETA) on your device. It may take up to an hour, so prepare accordingly (enough battery, time).

After copying it should state 'OK' for all copied files. If it doesn't then it's likely that you have a faulty CIT file on the external SD/USB media (return to step 3 or 2, if you suspect a faulty download).

After exiting this dialog the device will automatically restart and when it starts again you can verify installed and used maps in “About” dialog.

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.

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

Page 54 of 192

Operating Modes Version 6.03, May 2017

type. Turn the ZOOM selector 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). Image below shows example of combinations of Width and Colour property and rendering of airspace zone.

You can set separately airspace colour and border for side view and map view, if option Copy styles to side view is not checked. Press the DEFAULT button to reset these settings back to default.

5.1.6.3 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. If duplicates is checked, duplicated points might be shown on map, when same waypoint(airfield) is defined in user file as in airport database. Use show only airports from database to display only airports from database on airport mode.

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 (all types, all landable, unknown, waypoint, mountain top, grass airfield, outlanding, glider site, solid airfield, mountain pass, sender, VOR, NDB, Cooling tower, Dam, Tunnel, Bridge, Power plant, Castle, Intersection, Marker).

Operating Modes Version 6.03, May 2017

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.

 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.

 Team code: shows the team code for that waypoint.  Frequency will display the point frequency, if available.

Define minimum runway length and minimum runway width to filter our too short and too narrow runways. Such landing places will be shown in nearest list anyway, but they will be marked with red cross to indicate, they are not usable.

5.1.6.4 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:

 Fixed path style. Path colour is fixed and defined by path colour item.  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.

 Vario path style, where red colour indicates positive vertical speed and blue colour

negative vario values.

 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.

 Netto path style, where red colour indicates positive netto vertical speed and blue

colour negative netto values.

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. 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.

Use Show glider range area to display reachable area from current altitude with current wind and MacCready settings. Use area colour and area border to define its properties. Area can be filled outside or inside. Glide ratio defines the past flown average efficiency which will be used for average efficiency calculation for glider range area. Press the DEFAULT button to reset these settings back to default.

5.1.6.5 Thermal mode

When entering thermal, display unit can enter special page, which is called thermal page. See chapter 6 or LX Styler manual how to define thermal page.

Check Enabled to enable thermal page option. Displayed path on thermal page can be different from the one defined in Glider and track dialog. Use length, line and colouring properties to define path display. Also page zoom is different and set to fixed value defined with Page zoom property. Switching to thermal mode can be done in 2 ways: Circling detection or Switching SC/Var. If you start circling the thermal mode will become active at the angle of turn (set switch angle), or if you switch from SC to Vario mode. Circles are coloured based on following methods: Auto span, MC or Average Vario.

5.1.6.6 Optimization

The main display unit calculates the optimised flown distance according to OLC or FAI rules in real-time during flight (see Chapter 5.1.8). 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

These lines will always be plotted in kilometres scale regardless of the Units value.

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.

5.1.6.7 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.

When Show optimal track is enabled, small blue arrow is drawn next to aircraft. This arrow indicates most optimal direction to fly.

AAT isolines are showing expected speed, delta time or expected distance, which means if you turn to a next point at any of the lines, you will have the results indicated next to the line based on the calculation to the next turn point zone.

AAT fill is filling the zone. Zone becomes transparent if you are “too early, too short or task delta time is not 0”, if the zone is solid colour, you are already “too late, flew too long in the zone or your task delta time is not achievable”.

5.1.6.8 Flarm

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. 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.

SC volume item is visible only for variometer before V5 variometer, where it was not possible to separately set volume for speed to fly mode and for climb mode. It is highly recommended to upgrade variometer to newer one. Please contact

info@lxnav.com for more details.

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.

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.

Page 64 of 192

Operating Modes Version 6.03, May 2017

Mixed item is visible only for variometer before V5 variometer, where it was not possible to separately set volume for voice messages. It is highly recommended to upgrade variometer to newer one. Please contact info@lxnav.com for more details.

Volume level (loudness) can be also set with volume rotary knob, when messages are being played

5.1.7.2 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.

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 main display unit will generate an alarm at the time of event.

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

5.1.7.4 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 5.7.2).

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.

Page 66 of 192

Operating Modes Version 6.03, May 2017

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 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:

Optimisation will not take into account the 10 km distance between turn points which is required by FAI rules.

5.1.8 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.

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.

5.1.9 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, Time Alarms are raised at defined time interval to remind pilot to do specific task, Gear warning is triggered at pre-defined above ground level altitude setting and Waypoint warning will be given at set distance to Waypoint.

Use this dialogue to setup the behaviour of warnings.

Operating Modes Version 6.03, May 2017

5.1.9.1 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.

Operating Modes Version 6.03, May 2017

5.1.9.2 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.

Altitude warnings can be set for approaching from below defined altitude or from above defined altitude.

Page 70 of 192

Operating Modes Version 6.03, May 2017

On competition it is recommended to set to Medium or high alarms, otherwise too many warnings will be displayed. Medium or High, means only the most important alarms will be triggered.

5.1.9.3 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.  Obstacles warnings will be displayed when a collision with a ground obstacle is

predicted. Obstacles file should be loaded.

 Alert zones are marked by ground stations to notify pilots of active parachute

dropzones, RC/RPAS/UAS flying areas or similar

 Low alarms, Medium and High alarms combo box defines alarm level at which

system will display collision warning.

Explanation of alarms:

 Low alarms: For distant Flarm targets the main unit gives a short or long message,

just a beep or be turned off. (19-25 seconds before possible collision).

 Medium alarms: For distant Flarm targets the main unit gives a short or long

message, just a beep or be turned off. (14-18 seconds before possible collision).

  High alarms: For very close Flarm targets main unit gives a short or long message,

just a beep or be turned off. (6-8 seconds before possible collision).

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.

 True bearing: Direction is give with absolute direction (e.g.

Traffic 3’ o clock

, which means traffic, is on your right side).

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 Hardware*

Use this menu to define hardware properties such as total energy compensation, vario indicators layout, compass calibration, FLARM module settings, AHRS settings, Wi-fi module, 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.

Operating Modes Version 6.03, May 2017

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.

TE (Pst) Vario unit

Digital TE compenstaion

Compensation with TEprobe

5.1.11.1 Vario unit settings – TE compensation*

All settings in this menu are related to the glider and thus they do not depend on profile selection. In this manual dialog description is given for firmware version 5.0 or higher with V5, V8, V9, V80 variometer. In case older version or older variometer is being used, please refer to previous version of manual.

Total energy compensation, temperature offset, airspeed offset and digital inputs are setup in this menu.

5.1.11.1.1 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.

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.

Page 75 of 192

Operating Modes Version 6.03, May 2017

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.

Vario indicator will ignore this setting and shows not corrected airspeed.

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.

5.1.11.1.2 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.

5.1.11.1.3 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.

5.1.11.1.4 Digital inputs

V9 or V5 variometer is having six programmable digital inputs. Two of them a bit special and are labelled VP and SC (since August 2015 SC is no more wired via cable), others are labelled with IN1, IN2, IN3 and IN4 on V5/V9 cable-set. See Installation manual for more details on vario unit wiring diagram. In current version digital input can represent the state of following actions:

 SC on/off switch is used to change between SC (cruise) and climb mode using

on/off switch on remote stick of magnetic switches on flaps. Use invert check box to invert working of switch.

 SC toggle button is used to change between SC (cruise) and climb mode using

push button on remote stick. Use invert check box to toggle when button is pressed down or released.

 Vario priority is used to instantly change from SC (cruise) to climb mode as long as

push button is pressed.

 Gear down and locked should be connected to gear only.  Airbrakes locked should be connected to airbrakes only.

Page 76 of 192

Operating Modes Version 6.03, May 2017

Instead of using magnetic switch on flaps to toggle between SC (cruise) and climb mode you can also use flap sensor for this operation. See chapter

5.1.11.14.

There is another input called VARIO PRIORITY. When this input is activated by grounding the appropriate wire the unit will change to Vario immediately. This input wire is set open (not grounded) as a factory default on delivery.

Page 85 of 192

Operating Modes Version 6.03, May 2017

Extract from the Flarm manual:

Warnings are given in order of the time remaining before a potential collision, not the geometrical distance. The first warning level for another aircraft or an obstacle is delivered at less than 19 - 25 seconds before the possible collision; the second warning level is delivered at less than 14 - 18 seconds before; the third level at less than 6 - 8 seconds before.

The central number and chevrons indicate if the Flarm target is below or above and by how many meters/feet. The number in the bottom right indicates the range in meters/feet. The numbers are related only to the closest or the most dangerous target.

5.1.11.4.6 Thermal assistant Mode

The Thermal Assistant mode displays a graphical representation of your location within the thermal. If you are thermaling to the left there will be an aircraft symbol on the right of the ring of bubbles and the bubbles will appear to rotate clockwise (towards the symbol of the glider). If you are in a right hand thermal there will be an aircraft symbol on the left and the ring of bubbles will appear to rotate anticlockwise (towards the symbol of the glider). Large red bubbles indicate the strongest lift within the thermal and small blue dots indicate the weakest lift or sink within the thermal. Yellow bubbles indicate lift equal to your MacCready setting, average thermal or average climb rate depending on your preferred setting. The point of strongest lift is indicated by a white large bubble.

You can use the thermal assistant to visually determine which part of the thermal has the strongest lift and adjust your turn accordingly to maneuver the glider in the direction of the strongest lift and away from the weakest lift or sink.

The two NavBoxes within the Thermal assistant Mode can be configured on the LX80/90xx, the first and second navbox lines.

Classical external flarm can be updated through the main device. Power flarm can be updated only via USB key.

5.1.11.7 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.

Press CLEAR button to delete all data on Flarm module. This will remove also obstacle database.

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, Baudrate selection will be displayed Freq shows selected frequency depending on the continent, where system is located. Flarm Frequency is automatically updated based on the current continent.

Port defines serial interface through which Flarm data are being received.

 Internal is default setting and indicates that internal Flarm will be used, if installed this

option.

 Ext. (Colibri) (only on LX8000 old model)– Use this mode, when you want to receive

external Flarm data through Colibri port on back side. (For example, if TRX1090 is

connected to LX8000.)

 Ext. (PC) – Use this mode, when you want to receive externally connected Flarm on PC

port

 Flarm – port is available on selected devices only and means that Flarm input will be

via port labelled Flarm.

 GPS – port is available on simple type of devices only and means that Flarm input will

be via port labelled GPS.

See installation manual and Chapter 10.1 for more details. Device ID shows the Flarm unique ID, which is transmitted to other FLARMs.

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.

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 6.2.1.9.

Flarm internal number can be seen in the last row, next to the current SW version. Internal number will not appear immediately after powering on the main device, it can take up to 5 minutes. Internal flarm number can be also seen from the IGC file.

It is very important that compass is installed away from power cables, other compasses, speakers and all other magnetic components in the aircraft. Keep maximum possible distance to such components (at least 30cm).

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.

Reduce warnings will significantly reduce Flarm warnings. Use this option if you are flying in gaggles or areas with high density of other aircraft.

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.

No tracking will disable tracking mode. If set, receiving ground stations do not process or store position data of aircraf

You can also see your flarm serial number, version and obstacles loaded (if they are loaded).

5.1.11.8 Compass*

When a compass is connected to the system use this menu to perform calibration of it. Before calibration, please make sure that compass is installed properly. Refer to compass and installation manual for more info about installation.

5.1.12 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 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 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 5.1.2).

Ballast dump rate is used for calculation of water dump rate. If dump rate is specified and

water dump input is installed, system can measure amount of dumped water and thus automatically adjust ballast. Use this table to specify dump rate for a selected amount of water. At least one point must be entered. If there is only one point, it means dump rate is constant all the time. Press SPEEDS button to enter speeds dialog. In this dialog all speed for glider and flap labels are set. Speeds should be given for a reference weight. Stall speed is used to generate stall warnings which are available only with the LX Voice module. 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.

5.1.13 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 6).

 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 5.1) or with LX Styler.

An active profile is selected when the system is powered on (see Chapter 7.1.2).
