Version: 1.7 Page 5 of 47 Later in manual “backup mode” will be written from time to time. Backup mode is when LX Eos is used in LX Zeus system and while flying, system loses main power. LX Zeus will turn off, but LX Eos will use internal backup battery to continue working. All functions of LX Eos are operational in backup mode so pilot can safely navigate back to home or complete the task. LX Eos can be used in two different configurations: - a standalone: LX Eos represents vario navigation system and has all options active. Unit will turn on when enter switch is pressed. - LX Zeus configuration: LX Eos serves as vario system controlled from LX Zeus. Unit will turn on automatically when main switch is turned on. All setup settings are set on LX Zeus. Flarm radar settings and thermal assistant settings must still be set on LX Eos. Some of options are disabled (setup, task edit) but all of LX Eos options will become active when backup mode is detected. Unit has capability to be updated to any later FW release. As standalone system, please refer to Setup/SD Card/Update, how to update the system. As LX Zeus configuration, LX Zeus will automatically update LX Eos if required to latest version, so no extra action is required. 1.1 Hardware specification Picture shows the LX Eos unit. It is 57 mm sized all in one vario – final glide calculator, flight recorder, Flarm display, basic navigation etc… with one rotary switch with push button for all operations. Dimensions 60 mm x 60 mm x 75 mm Weight 220 grams Input Voltage Range 9.0 – 20.0 VDC Average Current 140 milliamps @ 12 VDC Bluetooth range up to 20 meter

Initial setup screen is not visible, because all initial setup is done on LX Zeus unit. 1.4 Switching off the unit When on ground (flight recorder is not running), disconnect main power supply from system. LX Eos will start to count down 3 seconds before it will turn off. If you are flying (LX Eos detects IAS – indicated air speed and flight recorder is running) it will not switch off until flight is ended. Flight will end 10min after landing or manually by the user. How to manually end flight, please refer to section of statistic page. 2 Use of rotary switch To move around and access all functions of the unit, one rotary switch with push button is used. Push button operation will be later in manual called as “enter”. To change value of setting, enter must be pressed to activate field (white frame will change to yellow). Yellow frame indicates that selected value can be changed by rotation of rotary switch. To exit edit mode press enter again (frame becomes white again). For quick change (multiplication by 10 steps) press enter button and while being pressed, rotate rotary switch.

Version: 1.7 Page 7 of 47 To exit from any subpage or list, pilot has 2 options: - Select “Exit” option which is always located at the end of each page / list - Move to the top of each page / list where red circle with white X is located. Exit option is activated, when this circle becomes filed with red. Exit at the bottom. Exit at the top. Value can’t be change (white frame). Value can be changed with rotary switch (yellow frame). Green cursor indicates the character which is being edited. Edit character with rotary switch. Pressing enter on “arrow” symbol will finish the string. 3 Initial setup Initial setup screen is first one after power on, where user can select pilot from internal database and set airfield elevation with daily QNH setting. This screen is visible only as standalone version. If used in LX Zeus configuration, all this settings are done on LX Zeus and this screen is not visible on LX Eos. Select pilot from the internal database with rotary switch. If there is no pilot in database, “Empty” pilot is offered and can be later edited (name, surname,…) in Setup/Pilot menu. Code input will be required if selected user has his profile protected with user code. Set airfield Elevation. Modify suggested QNH setting.

Version: 1.7 Page 10 of 47 6 Thermal assistant page Thermal assistant page can assist pilot when thermaling to get better sense how thermal looks like. Thermal is presented with use of different coloured dots. Default color scheme: White coloured dots shows maximum climb detected in last turn. Width of dot represents strength of climb/sink. Red dots represents climb. Blue dots represents sink. MC color scheme: White coloured dots shows maximum climb detected in last turn. Width of dot represents strength of climb. Red dots represents climb which is stronger than 1.2*MC setting. Yellow dots represents climb in range of 0.8*MC and 1.2*MC setting. Blue dots represents climb less than 0.8*MC setting. If MC setting is less than 0.5m/s, default color scheme is used! In the middle, wind indicator is shown as a green arrow with numerical indication for direction and speed. Wind arrow is track up orientated. Other marks on this page: - Avg: Integrator value of vario. - M: Maximum value in thermal – white dot. Upper and lower navboxes are configurable in TA Setup: - T Avg: Average of thermal from start of circling until “now”. - Gain: Altitude gain from start of circling until “now”. - Alt: current QNH altitude - Netto: netto vario To access TA setup, press enter on this page. Auto TA: It is possible to enable automatic switch to thermal assistant from any other page when circling is detected. Max. beep: Position of max thermal (white dot) can be reported as a beep. If thermal beep is enabled, LX Eos will generate beep always when you are at position of maximum climb (white dot). Beep offset: Maximum thermal is announced with beep sound if max beep is enabled. Set beep offset in second here. Beep will be generated before you reached maximum thermal.

Version: 1.7 Page 11 of 47 7 Flarm radar page The graphic display is divided into 2 or 3 circles (depends on zoom setting). Last circle represents zoom distance. The white glider symbol is always positioned in the middle of the screen and shows the current position of the plane. Near gliders are displayed as yellow. All gliders located in radio range will be shown simultaneously on the display. ADSB object detected will be shown as green triangle pointing to its tracking direction. Non directional object are represented as red circle, which represents relative distance from plane. On the right the selected zoom is displayed. In top right corner vario information of selected Flarm object is shown and on bottom right corner its relative altitude compared to your plane is displayed. The graphic display orientation is always track up. To improve orientation, N, E, W and S are added to the display. Note! Gliders presented as a dot on the screen, are gliders where pilots have intentionally activated the PRIVACY mode on their Flarm unit. Gliders in privacy mode send limited data strings and can’t be visualized completely. However, all warnings will appear regardless of privacy mode. To access Flarm radar option, press enter on this page.

Version: 1.7 Page 13 of 47 8 TP navigation page This page can be used for simple navigation to turnpoint (TP). Before this page can be used, pilot must import TPs from external SD card (.CUP file) to internal TP database. How to import TPs please refer to section Setup/SD Card/Load TP. If LX Eos is used in LX Zeus configuration, TP database selected under TP/Task/Eos list on LX Zeus is automatically transferred (first 1000 points). TP is displayed as yellow dot and white line from dot to plane is showing direction in which the pilot should fly. Navigation is always “track up”. On the top of this page pilot can find name of navigated TP. Under the name, final glide information to the selected point is visible. Final glide calculates reserve altitude into end result. Navbox-es shows track (TRK), bearing (BRG) and distance (DIST) to the selected point. Under the plane, steering symbol information will give pilot information for how many degries (°) does he need to correct his track to fly directly to the point. Pilot can select a TP, to which he would like to navigate, with press on enter button. Select option will be offered only on LX Eos as standalone or in backup mode. To select new point of navigation in LX Zeus configuration, select new TP on LX Zeus TP page. On header, number of TPs found, is reported in bracket. TP database must be first uploaded using Setup/SD Card/Load TP option. With filter field, pilot can filter out alphabetically, which point is being searched. Example is showing use of filter “CE” where 28 points are found. Pressing enter on any point will automatically select it and navigation will start on that point. Selected point is saved after power reset. Configuration with LX Joy: When LX Joy is connected to LX Eos standalone configuration, up/down keys will change zoom settings on TP page. In configuration without LX Joy or LX Zeus configuration, zoom change is not possible!

Version: 1.7 Page 14 of 47 9 Task navigation page This page can be used for simple navigation on predefined task (TSK). Before this page can be used, pilot must import TPs from external SD card (.CUP file) to internal TP database and set a task in TSK SETUP. How to import TPs please refer to section Setup/SD Card/Load TP. Navigated task TP is displayed as observation zone and white line from zone to plane is showing direction in which the pilot should fly. White line from center of observation zone will show next leg of task. Navigation is always “track up”. On the top of this page pilot can find name of navigated TP. Under the name, final glide to the end of the task is displayed. Navbox-es shows track (TRK), bearing (BRG) and distance (DIST) to the navigated point. Under the plane, steering symbol information will give pilot information for how many degries (°) does he need to correct his track to fly directly to the point. Configuration with LX Joy: When LX Joy is connected to LX Eos standalone configuration, up/down keys will change zoom settings on TSK page. In configuration without LX Joy or LX Zeus configuration, zoom change is not possible! Pressing enter, “TSK SETUP” is activated where task TP can be added, selected or removed from task. TP database must be first uploaded using Setup/SD Card/Load TP option. On first row task total distance and task type is shown.

Pilot can either select pilot that is already saved in the database or select “EMPTY” to create a new pilot. If pilot is already saved, name initial and surname are shown. Pilot name or “EMPTY” is automatically shown in the second line. Code input will be required if selected user has his profile protected with user code. - Pilot name: edit the name of the pilot. - Pilot surname: edit the surname of the pilot. Pilot’s weight is added to the whole weight of the plane to calculate actual wing load factor. - Weight: edit the weight of the pilot. Co-pilot’s data is visible in flight declaration (IGC file). - Copilot name: edit the name of copilot. - Copilot surname: edit the surname of copilot. Co-pilot’s weight is added to the whole weight of the plane. - Copilot weight: edit the weight of copilot. - Set user settings password. Password 0000 will unlock protection! Export/Import user profile to/from SD card.

Version: 1.7 Page 21 of 47 14.2 QNH/Res Pilot should set actual QNH and elevation of the airport where he will take-, off on initial setup screen. After change of QNH during flight, pilot can change altitude information to which final glide will calculate. If QNH is changed on the ground, altitude will not be corrected and will still be the same as set on initial setup. Reserve is the safety arrival altitude that instrument adds to the required final glide altitude so that the glider arrives over navigated destination with selected reserved altitude. Pre-set elevation can be set to QFE or any elevation value from 2m – 2000m. This pre-set elevation will be offered at initial setup. If pre-set elevation is set to OFF, elevation based on 1013mBar or GPS altitude will be offered at power on. 14.3 Vario/SC In this menu pilot can set following settings: - Altitude sensor setting sets from which sensor displayed altitude and altitude used in FG will be taken from. Pilot can choose between IGC sensor (canopy pressure) or from sensor connected to TE/Pst static intake. - Zero frequency is a frequency generated at 0 m/s - Positive frequency is frequency at maximum climb shown on scale (depends on range setting). - Negative frequency is frequency at maximum sink shown on scale (depends on range setting). - Audio test will generate vario movement from +6m/s to -6m/s so user can check audio setting in this range. - Range is the scale for vario. Three options are available – 2.5, 5 and 10 m/s (5, 10 and 20 kts, according to user selected units). - Filter defines the dynamic of vario needle and sound. The smaller the time the faster is response and vice versa. - Avg time is setting that defines integration period for averaging the vario data in seconds. - Vario silence will mute vario beep for all vario values less then set value. TE Level is the level of electronic TE (total energy) compensation for variometer. Selection of electronic compensation method is done after selection of TE level. 0% means total energy compensation using a TE probe. After an input of a percentage, which is more than zero the special software routines will be activated and will provide an electronic compensation process. The TE compensation can be fine-tuned during flight with the following

Version: 1.7 Page 22 of 47 procedure. It is essential that this is only done in smooth air; it is not possible to tune the TE accurately when there is thermal activity. - Select 100 % TE level. - 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 maneuver. At 160 km/h (75 Knots) the vario will indicate about –2 m/s (-4kts). 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, then the compensation is too low, increase the TE level; and vice versa. Repeat this procedure and make further adjustments if necessary. - Max SC Speed will mute SC sound when IAS is above set value. SC mode: - Manual: pilot will activate the SC mode with push of an external button. Activate settings of SC button can be set under SC Switch option. - Speed: SC mode will be automatically activated when the “SC speed” is exceeded. - Circling: SC mode will be automatically activated when LX Eos detects that you left thermal, and will automatically switch back to vario mode when you enter next thermal. With the use of external switch it is possible to switch between SC and vario manually, if manual SC mode is selected. - SC Switch: • ON means that closing of the switch will cause SC mode. • OFF means that closing the switch will select vario mode. • Toggle each press of the button will change between SC and vario mode. - SC Speed setting is the speed value at which the SC Mode is activated if SC mode is set to speed. - SC Silence defines no audio area around zero in SC mode.

Version: 1.7 Page 23 of 47 14.4 Polar Nearly all gliders polars are stored in the LX Eos memory. It is also possible to create a user defined polar. Not editable data is coloured blue. It is always possible to edit empty weight of the glider. To create customs polar find “USER” in first line. When “USER” is selected all polar data will turn to white so the pilot can edit them. With ballast dump setting, pilot can set how many kg/min will be dropped out when using ballast switch on ballast valve. Whit this setting, ballast will be automatically reduced when valve is opened.

Version: 1.7 Page 24 of 47 14.5 Units Pilot can set units for: - Vario (m/s, kts). - Altitude (m, ft). - Distance (km, nm, mi). - Speed (km/h, mph, kts). - Wind (km/h, mph, kts, m/s). - Pressure (mbar, inHg). - Temperature (°C, °F). - Weight (kg, lb). - Area (m2, ft2).

Version: 1.7 Page 26 of 47 14.7 Logger 14.7.1 Event Set number of event fixes and event record interval. Event is activated when event button is pressed. 14.8 Warnings Warnings are used to inform pilot that some flight related data is outside margins. When warning state is detected by LX Eos, pilot will get red warning message box with description of what is outside margins. Pilot can enable (box is checked) audio warnings and Flarm warnings. - Audio: if disabled, voice warning will not be generated – only visual as warning message box. - Inputs: Must be turned on to enable input port warnings such as airbrakes, gear, … - Flarm: Flarm warning page will be seen only on Flarm radar page if this flag is disabled, otherwise it will override any Eos page/menu when warning is detected. The pilot can set recording interval, registration number of the plane, competition id, competition class and event settings. All this data is then seen as declaration in every IGC flight file. Dec. Flarm: Send declaration on Flarm port. If connected to Zeus, this is done automatically.

Version: 1.7 Page 27 of 47 - Altitude warning: warning when flying over selected altitude - Stall: warning when the glider speed is lower than stall speed - Vne: warning when speed exceeds Vne speed 14.9 Voice Pilot can set the voice volume of the device and mixer settings. The percentage of mixer means how much voice is mixed with vario beep. Low percentage means lower voice to vario beep ratio and higher percentage means higher voice to vario beep ratio. Enabling Flarm traffic option will generate voice announcement when new Flarm object is detected. Enabling Flarm warning option will generate voice warning when Flarm collision warning is detected. Enabling Flarm obstacle option will generate voice warning when obstacle from Flarm database is detected in front of the plane. With F. Horizontal Dist setting, user can enable/disable horizontal voice information for Flarm traffic. With F. Vertical Pos setting, user can enable/disable vertical voice information for Flarm traffic.

Version: 1.7 Page 28 of 47 14.10 SD Card External SD card is used for all data transfers to LX Eos. In this menu all import/load functions from SD card can be accessed. 14.10.1 Load TP After selecting “Load TP” option, list of all CUP files (up to 20) found on external SD card in LX/TP folder will be listed here. Select file from which you wish to import TPs to internal database. Cup file is commonly used file for transferring TPs and tasks (optionally). LX Eos can import turn points by name or by code. Warning: CUP file is usually alphabetically sorted by name. Lx Eos must have alpha sorted TP base or it will do it on import. If this is the case, import can take a long time (depends on number of TPs). When import by “Code” is selected, it will take much longer then import by “Name”! After selecting import mode, the process can take from 5 sec up to 10 min (depends of TP number and alphabetical sort inside CUP file). Number of TPs is not limited but we recommend to use CUP file with up to 1000 points. Name of every TP will be shorten to max 11 characters after import.

Version: 1.7 Page 29 of 47 14.10.2 Load TSK After selecting “Load TSK” option, list of all CUP files (up to 20) found on external SD card in LX/TP folder will be listed here. Select file from which you wish to import TSK to internal memory. After selecting file from which you wish to import task, first 20 task found in the file will be listed. Select task you wish to import and press enter. Observation zones will be loaded as well if defined in file, else standard FAI zones are used. Warning: Due to internal task limitations, only first 18 points of selected task will be loaded from file. Wait until load is finished. 14.10.3 SD init Pressing enter will create LX folders on external SD card. This function is recommended after use of new SD card. The unit comes with already initialized SD card. 14.10.4 Update Before update, user should request update code at: [email protected] In email request, user should provide serial number of the unit and version to which he wish to update to. Pilot should copy new version to root of external micro SD card, then insert it into the LX Eos and use “Update” option to make an update of the unit. After selecting “Update”, list of all version (*.lxu) files will be listed. Pilot should select version, which he wishes to update to. After selection, update code request will be visible. Update code can be accessed on [email protected]

Version: 1.7 Page 30 of 47 After code is entered, LX Eos will report error, if code is not correct or start update. Update can take up to 4 min. Device will automatically restart after successful update. LX Eos will also update all LX CAN devices connected to the system. 14.11Inputs LX Eos has a possibility of five different user defined inputs. Each input can be set accordingly. There are seven options to choose from: - None: nothing is connected to the input. - SC: the device changes mode from vario to SC mode. - VP: (vario priority) the device goes to vario mode no matter in which condition is SC mode. - Event: event in flight recorder is activated and pilot gets a message shown on display. - Gear: If enabled under warnings will generate gear up/down warnings after takeoff / before landing. - Airbrakes: if enabled under warnings, will generate airbrakes warning if they are opened during takeoff. - Ballast: when active will automatically reduce ballast mass for value set on polar page (ballast dump) Inv – invert mode: Each input has invert option. When invert option is enabled, it will “invert” active state of this input. Invert option: - off: input is active when switch is closed - on: input is active when switch is opened A and N characters shows actual state of input. ‘A’ means ACTIVE and ‘N’ means NOT ACTIVE. If two or more inputs are the same, the corresponding action will be made when all of them are active (active = switch closed or switch open in Inv mode!). How to connect switches to external switch interface, please refer to external switch installation section. Functions of inputs: SC: LX Eos supports two modes of operation Vario and SC. With SC input, user can change between these two modes. VP: Vario priority is used when user won’t to have vario mode active. VP input has higher priority than SC input! Event: To trigger pilot event in logger with higher recording interval, this option of input should be selected. Gear: If any of inputs is selected as gear, gear warning will be announced at next conditions: - gear is out 10min after take-off is detected and height is more than 500m above take-off location. - gear is not out and altitude is less than 200m in 5km circle of take-off position and flight time is more than 5min. - on outlanding (if airbrakes are out, elevation less than 600m QFE, distance from takeoff more then 5km) and gear is not out.

Version: 1.7 Page 31 of 47 Airbrakes: If any of inputs is selected as airbrakes, gear warning will be announced at next conditions: - airbrake is out during first 10min of flight (take-off / aero tow time). 14.12 NMEA This setup page is used to set which data is being sent to third party unit connected thru BT or user port. The pilot can set baudrate for communication over User port or Flarm port. Pilot can select from: BR4800, BR9600, BR19200, BR38400, BR57600 and BR115200 options. LX Eos is capable of sending NMEA data to third party units such as PDA or PNA. The data is available on the connector marked as USER and BT port. Five data strings are offered. Selected (checked box) NMEA data will be sent over User port and Bluetooth. - GPGGA – Global Positioning System 3D-Fix Data. - GPRMC – Recommended Minimum Specific GPS/TRANSIT Data. - GPRMB – TP navigation info. - LXWPx – sentences contain pressure and altitude information in addition to IAS data. - PFLAx – Flarm traffic info. Data must be enabled, if Flarm data is required on a PDA. - Radio – Enable this option when radio is connected to user port. Control over the radio is only possible in configuration with LX Zeus. LX Eos as stand alone will not be able to control radio! - Transponder – If enabled, baudrate on Flarm port will go to 9600 and GPS data will be transmitted on Flarm port. When Radio option is enabled all other outputs on User port are disabled, but are still present on BT port.

Version: 1.7 Page 32 of 47 14.13 Pages The pilot can select which main pages are active. Page is active when box is checked. There are five main pages available: - TA (thermal assistance). - Flarm radar. - TP (turnpoint). - TSK (task) - G-Force page - GPS info (basic GPS information’s) - Info page (OAT and voltages) 14.14 Password To access some options, password is required. Available password’s are: - 46486: sets LX Eos to factory settings. - 99999: clear all flights from flight recorder – logbook is empty. - 28346: audio player (will play any wav file 8bit 16kHz mono from root of external SD card). - 66666: clear actual task. - 55555: clear internal TP database

Selecting “No” will return you back to setup menu, while selecting “Yes” will turin off the unit. If shutdown option is selected during flight, this message will be shown. Plese finish the flight first and then turn it off! 14.16 Info LX Eos info page. Displayed information: - Serial number. - IGC serial number. - Software version. - Hardware version.

Version: 1.7 Page 34 of 47 15 Bluetooth module LX Eos has internal Bluetooth 2.0 module which is always on and cannot be turned off. At the back of the unit, there is external Bluetooth antenna, that enables better range (brown cable). 15.1 Pairing with PNA Perform search of BT device on your PNA/PDA (Oudie, Mio, …). LX Eos XXXXX, where XXXXX represents serial nr of the unit, will be visible on device list, when in range and turned on. Pair code will be requested to start communication with PDA/PNA and Lx Eos. Enter pair code: 1234 After successful connection, Bluetooth icon is visible on main vario page. 15.2 Supported data transfers Description Supported Remark GPGGA yes If enabled in NMEA setting GPRMC yes If enabled in NMEA setting GPRMB yes If enabled in NMEA setting LXWPx (Lx data) yes If enabled in NMEA setting PFLAx (Flarm data) yes If enabled in NMEA setting and Flarm is connected to Lx Eos Declaration from Eos no Declaration to Eos yes CUP file transfer no Flight transfer no 15.3 Usage Bluetooth communication is designed to be used in double seat gliders, so 2nd seat PDA/PNA can get all the data via BT or when only power cables are provided in glider for PDA/PNA (Club gliders). 16 User port LX Eos uses User port (RS232 standard) to connect to third party devices such as PDA/PNA (Oudie, Mio,..), radio (KRT2) Connect any third party device only with LX Navigation supported cable. Any unsupported cable may damage LX Eos or third party device beyond repairs. For successful communication correct BR must be selected under NMEA settings. Note: For some PDA (for example HP314 ....) it is preferable to set the USER Port at BR115200 or at least at the maximum BR that is supported by the PDA. This can help to avoid communication problems during the declaration from PDA to LX Eos 16.1 Supported data transfers Description Supported Remark GPGGA yes If enabled in NMEA setting GPRMC yes If enabled in NMEA setting GPRMB yes If enabled in NMEA setting LXWPx (Lx data) yes If enabled in NMEA setting PFLAx (Flarm data) yes If enabled in NMEA setting and Flarm is connected to Lx Eos Declaration from Eos no Declaration to Eos yes CUP file transfer no Flight transfer no KRT2 radio control yes If enabled in NMEA setting and LX Eos is connected to Zeus.

Version: 1.7 Page 35 of 47 17 Upload Task on LX Eos The user can transfer the Task to LX Eos using two ways: - With a microSD as explained in chapter 12.10.2 "Load TSK" in relation to TPs and their view zone. - With a PDA connected to User port or via Bluetooth. This way the user can only send the IGC declaration according to FAI rules. They will be transferred to LX Eos the TPs and the view zone of the start line and of the finish line. A standard FAI view zone (90°) will be assigned to all intermediate TPs. The user can later change, if necessary, the view zone directly in Task page of LX Eos (see Chaper.9). 18 Installation of the unit 18.1 Mechanical installation LX Eos fits in standard 57mm hole in instrumental panel so no extra cut out is required. To fit LX Eos in instrumental panel unscrew three mounting screws (black) with a screwdriver and knob of rotary switch. To remove the knob do not use force. Remove the press-in cover first to get to the screw. After unscrewing the screw pull off the knob. Place the LX Eos in the hole in instrumental panel and first screw in the three black screws and then put back the knob on the rotary switch. Don’t forget to screw the knob in place and put the press-in cover back on.

GPS antenna Connect external GPS antenna to this connector. LX Eos must have external antenna connected all the time, else internal flight recorder will now work. 18.4 External switch installation Up to five external switches can be connected to LX Eos. To connect external switch to LX Eos you have to use external switch interface board (included in package). Every slot available has a signal input and ground input. The configuration of inputs can be set under Setup -> Inputs. User can use two different connection styles: - 2 wire connection: Connect switch signal and ground wires to interface board. - 1 wire connection: Connect switch ground wire to glider common ground and connect switch signal wire to interface. Be careful not to connect signal wire to common ground input (see picture which are common ground inputs) Interfaces common ground is connected to glider common ground via power supply cable (GND). All inputs except SC will be “active” when switch is closed (signal and ground are in short circuit). If “Inv” (Invert) is checked on input setting then “active” means when switch is open. Example: airbrake warning will be active when switch is not closed and Eos is in flight mode. Warning will disappear when switch will be closed. SC input has its own setting under Vario/SC menu and can be set to be active on “on”, “off” and “toggle” state.

Version: 1.7 Page 39 of 47 Example of both connections (1 and 2 wire) 18.5 Installation of options LX Eos is compatible with all LX CAN based devices (LX Zeus, LX Joy, LX Eos Repeater, CAN Compass, AHRS, and others). LX Eos has an integrated CAN terminator so other terminator should not be used. Only one CAN terminator should be used (be careful when using LX Eos with LX Zeus). 18.6 Configurations 18.6.1 LX Eos – OUDIE OUDIE LX Eos PNA Power & Data LX Eos 18.6.2 LX Eos – Flarm 1:1 1:1 LX Eos Flarm Colour Display II (optional) LX Flarm spliter Flarm / RedBox MiniBox / Flarm Mobile FlarmMouse 1:1

Version: 1.7 Page 42 of 47 19 Flight Recorder Management The flight recorder doesn’t need any special care as it works nearly automatically without pilot assistance. All the pilot should do is to adapt the logger settings, see the Setup page / Logger menu chapter. 19.1 Start and Stop of flight recording The unit will start recording immediately after start conditions are met. Start conditions are based on ground speed and altitude change, so even if the GPS status is bad during takeoff, the unit will start recording. It is recommended to switch the unit on a few minutes before takeoff. This will ensure a straight base line of baro trace (IGC regulation). Running time before takeoff will not reduce memory space of the flight recorder, due to circular recording before takeoff. After landing the unit will close the flight after approximately 10 minutes at standstill, so it is recommended to keep the unit under power and GPS OK until the Calculating Security message appears on the display. To determine if the flight recorder has closed the flight, goto logbook/statistic page. If the Logbook appears, the recording has finished, if the statistic page appears, the recorder is still active. 19.2 Flight evaluation To check the flight data integrity use the IGC shell program. IGC shell is an IGC freeware program specially designed to verify the flight record integrity. Use the latest LXN.dll file to validate LX Eos flights. Latest version of LXN.dll is available on http://www.lxnavigation.com/software/

Version: 1.7 Page 43 of 47 20 IGC file structure IGC flight record file is text file, meaning the data are simply readable by any text editor.

Version: 1.7 Page 44 of 47 21 Baro trace check (calibration) Each flight recorder should be periodically checked to verify that the built-in pressure sensor is still in limits. The procedure is extremely simple and takes only minutes to finish. The most important action is setting the Rec. interval in Logger Setup to 1 second otherwise the trace will not be uniform. The procedure is as follows: -Turn the unit on and put it into the pressure chamber. -Set QNH 1013mBar conditions in the chamber. -Apply a pressure jump to start recording. -Climb apr. 4m/s and make a stop for apr. 30 seconds every 1000 m. -After reaching 8000m sink apr. 4 m/s and make stops after every 1000m. -After reaching zero open the chamber and wait for 1 min then manually end flight. -Download the “flight” from the logbook. -Return Rec. Interval setting to previous value. -Print baro trace using your preferred PC program, for instance Lxe (available on www.lxnavigation.com).

Version: 1.7 Page 45 of 47 22 Flying with LX Eos To get the best out of the LX Eos, it is important that some preparation is done prior to the flight – trying to configure the instrument or set up a task while flying the glider may spoil your whole day! Preflight preparation will ensure that the flight will be both successful and enjoyable. 22.1 Flight preparation on ground - Check if you have desired TP data base uploaded. - Prepare a task. - Enter flight recorder information (pilot name, surname, glider type, recording interval…). 22.1.1 Before take off - Switch the unit ON at least 3 minutes before take-off (this will ensure sufficient GPS reception and will create a base line of the baro trace). - Select correct pilot (many settings belongs to pilot) on initial setup or create new. - Check task if it is correct after using of Task stup. - The actual task during take-off will be declared in flight recorder automotically. 22.2 During flight The LX Eos HW and SW concept is so far optimized that the pilot doesn’t spend too much time to operate the unit during flight. A very significant indication that shows that the unit has changed to flying mode is Logbook replacement with statistics page. 22.2.1 Set QNH The pilot should input actual QNH value of the airport where he will take-off. This action should be carried out on ground, after take-off, change of QNH in Setup/QNH Res menu will adjust altitude reading to actual QNH setting. 22.2.2 Wind calculation LX Eos is able to measure wind under two different methods. Wind calculation results are shown on main vario page and on thermal assistant page. LX Eos will switch between straight and circling method automatically and history of wind will be counted in new measurements. Circling: Calculation is based on ground speed (GS) oscillation due to wind influence in circling. The method is active exclusively during climbing process. The process start automatically after circling is detected. The method is based on fact that the ground speed is affected by wind. GS is maximal by tailwind and minimal by head wind. This phenomenon is used by GS difference calculation method. Straight flight: On straight flight, wind will be calculated with use of iterative method which is based on IAS, GS and TRK measurements. 22.2.3 Influence of wind in final glide The actual wind data (speed and direction) influences the final glide calculation. In task mode the final glide indication is based on remaining distance over all TP until finish (not over already flown turn points). Wind influence for individual legs is based on current wind data.

Version: 1.7 Page 46 of 47 22.2.4 Event function User has option to set one of the user inputs to Event. If event switch is pressed during flight, it will enable faster record interval in flight recorder (recording in shorter intervals as default for a limited time). Event parameters can be set in Setup/Logger on LX Eos unit. The action is accompanied with a clear message. 22.2.5 Task start It is started automatically when glider leaves start TP observation zone. Navigation to next point will start. If pilot wishes to navigate back to starting point, he must simply use “Goto” option in task setup menu. Please refer to Task page chapter. No task statistic is available on LX Eos. 22.3 After landing It is recommended to keep the instrument ON for a few minutes after landing. This will ensure base line of baro trace. 10s after landing is detected, statistic page will be shown automatticaly where 10min countown can be seen. Pilot can wait for 10min of press enter to end flight. Calculating security message will follow and then logbook will be offered to the pilot. At this point unit can be switched OFF or flight download process can start. 22.3.1 Downloading flights Insert micro SD card to external micro SD card holder.
