SENSORS and AIR MANAGEMENT SOFTWARE mini USB socket micro SD slot micro SD slot USB Type C socket ▪ Main Features : o Dual purpose mini USB (or Type C in the Air-HG model) socket allows the Digifly AIR to be recharged with the supplied Digifly 5v charger and, additionally, to be connected to a personal computer or Mac for configuration & flight data management. o Micro SD card slot; use Class 10 cards with 8 to 32GB formatted FAT32. o Bluetooth System -AIR BT model only- for wireless communication with other electronic devices o Integrated Digi-FlyBox to send its Telemetry to another electronic device, via USB cable or via Bluetooth. This means sending the information from its sensors through a wireless communication system. o GPS receiver - 99 channels o Barometer (atmospheric pressure sensor) o Integrated anemometer – pitot tube (optional) o AHRS – 3-axis inertial platform: Spatial position and direction vectors relative to the 3 spatial axes. o 3-axis magnetic compass o 3-axis accelerometer o Free digital worldwide topographic maps. o Airspace upload and management. o Three Free management software programs both for PC or Mac: AirTools, AirPages and AirUpdater. o Optional Features: Integrated anemometer – Pitot Tube System AIR_Manual_610d_ENG_rev_1.pdf Page 7/104 2.2 BATTERY ▪ The main power is supplied by an internal rechargeable high capacity lithium battery, which has no memory effect, so it can be partially recharged, without affecting the battery’s life. It also has a very low self-discharge rate (about six months) and works very well at low temperatures. A fully charged battery will power the instrument for over 30 hours: when the battery icon starts to flash, you have approximately 4 hours left of battery power. ▪ Make sure your instrument is fully charged any time you put store it for a longer period of time (e.g. end of the flying season) or any time you know you won’t be using it for a while. ▪ To avoid permanent battery damage, you must ensure that it receives a full charge within 3 months of the last full charge. 2.2.1 BATTERY RECHARGE ▪ To recharge the instrument, connect it to a power source with the USB cable. ▪ Input: DC 5v is required and a 1A is recommended. ▪ The required time for a full charge is about 8 hours. ▪ There are no problems if you leave the vario charging for more than 8 hours, as the vario automatically switches to a “maintain mode” preventing the battery from being overcharged. ▪ The Digifly AIR’s lithium battery has no “memory effect”, so it can be also partially charged. 2.2.2 EXTERNAL POWER SUPPLY ▪ The mini USB socket can be used to power the instrument and simultaneously charge the internal battery. ▪ An external stabilized 5VDC power supply (e.g. a solar panel, external power bank, etc.) with a minimum of 150mA is necessary to turn the instrument on; any excess power will be used to charge the internal lithium battery. Proper solar panels are suitable to power the instrument. ▪ Important Notice: do not keep your Digifly AIR connected to its USB port in flight or in any situation where the USB cable could create an undesired movement to the charging port, applying force on the soldered connection of the mini USB, resulting in its detachment from the board. This also applies when you carry your AIR in your harness or a backpack: do not have the USB cable connected to it. AIR_Manual_610d_ENG_rev_1.pdf Page 8/104 2.3 KEYBOARD - NORMAL OR LONG KEY PRESS ▪ The time length you keep the keys pressed on your Digifly instrument selects the available functions. ▪ For a normal press: press the button for less than a second ▪ For a LONG PRESS: keep the button pressed down for at least 2 seconds Note: When not specified, the key press has to be considered as a normal key press (less than a second). 2.4 POWER ON & OFF ▪ To turn your Digifly AIR on, press the key for at least 4 seconds, until you hear it “beep”. ▪ To turn your Digifly AIR off, press the key for at least 4 seconds, until you hear it “beep”. If the logger is recording, you will be prompted to confirm your choice by pressing the key or, to cancel, press the key; it will automatically cancel the request within 3 seconds of no input. ▪ After switching your Digifly off, wait at least 5 seconds before attempting to turn it on again; this prevents unwanted operation. ▪ After turning your Digifly on, the first screen briefly shows the vario model, pilot name (if set), microSD status, logger status, vario serial number, firmware version and battery voltage. 2.5 DISPLAY CONTRAST ADJUSTMENT ▪ To change the contrast of the display, press the key to enter the “MAIN SETUP” menu, select CTRS (MAIN SETUP \ n. 1 CTRS), go to the edit mode pressing the key, set the preferred contrast using the keys: ‘arrow UP’ or ‘arrow DOWN’ , then save the changes by pressing the key. 2.6 MENU ▪ To navigate the menus of your instrument, press the key (“MENU” function). ▪ To select the sub-menus, scroll UP or DOWN the list using the arrow keys, then confirm your choice pressing the key (“ENT” function). ▪ To exit and get back to the main screen press the key (“ESC” function). AIR_Manual_610d_ENG_rev_1.pdf Page 9/104 2.6.1 STANDARD FIELDS EDITING ▪ To change parameters and settings, select the parameter you want to change by scrolling UP or DOWN using the keys, press the key (“EDIT” function) to enter in the edit mode. ▪ To change the value of the selected parameter, use the keys to select the new value, each parameter’s change is automatically saved (“AUTOSAVE” function) when you exit; keeping the , keys pressed activates the quick parameter change (“AUTOREPEAT”) function. ▪ To exit from the edit function, press the key (“ESC” function). 2.6.2 ALPHANUMERICAL FIELDS EDITING ▪ Changing the alphanumerical fields is different from the normal editing described above, because it is possible to modify every single character of the field. ▪ To modify the field, press the key (“EDIT” function) that activates the edit mode. ▪ Use the arrow keys to change the character shown in reverse mode on the display. Each parameter’s change is automatically saved (“AUTOSAVE” function) when you exit; a LONG PRESS of the arrow keys activates the quick parameter change (“AUTOREPEAT”) function. Pressing will take you straight to the alphabet. ▪ By pressing the key, you will shift to the character on the right and edit it; by pressing the key repeatedly you will scroll towards the right through all the individual fields until you go back to the first one. A LONG PRESS of the key moves back to the left; to exit press the key. 2.7 MULTI LANGUAGE HELP ▪ “Help” texts are available in the setup menus to guide you through the parameters. It is possible to set a language for these texts on the MAIN SETUP menu (MAIN SETUP \ n. 2 LANG) by selecting the preferred language. The change will be automatically saved when you exit. Another option is for you to create your own files using AirTools, save it and then upload it to the instrument. You cannot upload one single line at a time, you upload all the helps contained in a menu (Main, Advanced or Variometer). Important: after every firmware update, it is necessary to update the help file containing the help messages as well. The help file update can be performed from your PC/Mac using Digifly AirTools, function: “upload HELP”. 2.8 RESTORE FACTORY SETTINGS ▪ To restore the factory settings (default values for all parameters), with the instrument OFF, simultaneously hold down the & keys, until the message “FACTORY SET?” appears. Confirm with or cancel with . 2.9 RESET ▪ If a system crash occurs (resulting in the instrument freezing), press the (arrow down) and the (power) buttons at the same time for at least 5 seconds; this will force the instrument to turn off and reset, then turn your instrument back on normally.

AIR_Manual_610d_ENG_rev_1.pdf Page 11/104 3.2 PAGES ▪ The Digifly AIR features 13 pages: 12 configurable pages and one main page with GPS info, called the “MASTER INFO GPS PAGE " which, for safety reasons, cannot be changed or disabled. 3.2.1 CONFIGURABLE PAGES ▪ There are 12 configurable pages; each one is linked to one of the 12 configurable parameters (from MAIN SETUP\ n. 26 PG01 till MAIN SETUP\ n. 37 PG12) and for each page it is possible to configure a different layout: OFF = the layout view of the page is disabled (the page will be skipped) STD = it will show the corresponding Digifly standard layout USR = it will show the corresponding user layout created and uploaded by the user using the free Digifly program AirPages (for more details about software usage refer to chapter 14.1.2). ▪ REFERENCE TO NAME AND CONTENT OF CUSTOMIZABLE PAGES ▪ PG01 page_1_IntelliComp_flight_thermal OFF/STD/USR ▪ PG02 page_2_IntelliComp_flight_glide OFF/STD/USR ▪ PG03 page_3_IntelliComp_start_thermal OFF/STD/USR ▪ PG04 page_4_IntelliComp_start_glide OFF/STD/USR ▪ PG05 page_5_IntelliComp_goal_thermal OFF/STD/USR ▪ PG06 page_6_IntelliComp_goal_glide OFF/STD/USR ▪ PG07 page_7_IntelliXc_cross_thermal OFF/STD/USR ▪ PG08 page_8_IntelliXc_cross_glide OFF/STD/USR ▪ PG09 page_9_compass OFF/STD/USR ▪ PG10 page_10_relax OFF/STD/USR ▪ PG11 page_11_ahrs OFF/STD/USR ▪ PG12 page_12_map OFF/STD/USR Default page settings (in bold type) : PG1=OFF, PG2=OFF, PG3=OFF, PG4=OFF, PG5=OFF, PG6=OFF, PG7=STD, PG8=STD, PG9=STD, PG10=STD, PG11=STD, PG12=STD AIR_Manual_610d_ENG_rev_1.pdf Page 12/104 3.2.2 MANUAL PAGE SWITCHING ▪ To manually change the pages, press the key to go forward or the key to go back. You can manually switch pages even if you are in “Intellifly” mode. 3.2.3 AUTOMATIC PAGE SWITCHING (INTELLIFY) ▪ The automatic page-switching among the different pages is automatically managed by the Intellifly system, which recognizes the type of in-flight situation you are in at all times. ▪ Each type of in-flight situation is associated to a different set of pages (2 per set): Pages 1 and 2 are associated to a “Competition flying while navigating towards a standard waypoint” situation.; Pages 3 and 4 are associated to a “Competition flying while navigating towards a Start waypoint”; Pages 5 and 6 are associated to a “Competition flying while navigating towards a Goal waypoint”; Pages 7 and 8 are associated to a “Free Cross Country flying” situation; ▪ Each set of pages is formed by a “THERMAL” and a “GLIDE” version. The automatic page switching within each set of pages follows these criteria: It will switch to the “THERMAL” page when it notices a thermal that lasts longer than the value set on the VARIOMETER SETUP\ n. 22 THET parameter (default setting 2 seconds) and you make a turn to fly into it; it will switch to the “GLIDE” page when you fly “straight” for a period of time, longer than the value set on the VARIOMETER SETUP\ n. 21 CRUT (default setting 15 seconds). ▪ The MAIN SETUP\ n. 38 IFLY parameter sets the mode in which the Intellifly system will work : o IFLY=OFF: automatic page switching is disabled. o IFLY=CMP: automatic page switching is in “Competition” mode: when your current wpt is a standard one, it will automatically switch between PG01 and PG02; when your current wpt is the START, it will automatically switch between PG03 and PG04; when your current wpt is the one before last on your route (GOAL), it will automatically switch between PG05 and PG06. If I manually switch to a page outside the PG01-PG06 range, while on IFLY = CMP mode, the automatic switching will be paused until I manually switch back to one of the pages of the PG01-PG06 range. Remember to verify that all 6 competition pages are active: MAIN SETUP\ n.26 PG01 to MAIN SETUP\ n.31 PG06 = STD or USR (in case you have uploaded your own pages). o IFLY=XC: automatic page switching will be on “Cross Country” mode (default setting): it will automatically switch between PG07 e PG08. PG07 is the XC – Thermal page and PG08 is the XC – Glide page. If I manually switch to a page different from PG07 or PG08, the automatic page switching mode will be paused until I manually switch back to a page among PG07 or PG08. Remember to check that the 2 Cross Country pages are active: MAIN SETUP\ n.32 PG07 and MAIN SETUP\ n.33 PG08 on STD or USR (in case you have uploaded your own pages).

AIR_Manual_610d_ENG_rev_1.pdf Page 23/104 3.9.1 GPS STATUS INFORMATION ∙ The GPS icon signal has different meanings: o Static GPS icon = Correct GPS FIX (GPS position available) o Blinking GPS icon = poor GPS signal (valid GPS position NOT yet AVAILABLE) 3.9.2 LATITUDE & LONGITUDE COORDINATES ▪ The latitude and longitude coordinates are shown on top, referenced to map datum WGS84. 3.9.3 LATITUDE & LONGITUDE COORDINATES OPTIONS ▪ There are 4 different coordinate formats available, to choose from: DMS = degrees, minutes and seconds (dd° mm’ ss.s) - default DMM = degrees and minutes (dd° mm.mmm’) UTM = Universal Transverse Mercator (utm x, y, zone). DDD = decimal degrees (dd.ddddd) To set the preferred DMM, DMS, UTM or DDD formats, go to: MENU \ ADVANCED SETUP \ n. 24 CORD. 3.9.4 GPS SIGNAL QUALITY ▪ Type of Fix Information: GPS = normal fix, SBAS = fix with SBAS backing ▪ Number of Satellites Used for Fix ▪ The HDOP value represents the weakening of GPS signal; lower values mean good precision. 3.9.5 GPS ALTITUDE ▪ GPS altitude (“ALT GPS”) represents the height over sea level given by the GPS system. 3.9.6 GPS DIRECTION (TRK) ▪ GPS direction (“TRK”) represents the aircraft’s direction relative to the ground. 3.9.7 GPS GROUND SPEED ▪ The GPS ground speed is the aircraft’s speed relative to the ground (“Gs”). 3.9.8 REAL TIME NAVIGATION MANAGER / SKIP WAYPOINT ▪ The central part of the GPS INFO page shows the navigation progress of an active route in real time; you see the waypoint list of the active route, where the current waypoint is highlighted in "reverse" (white over black). ▪ In case navigation to a single waypoint is active, the central part of GPS INFO page will show only the name of the current waypoint. ▪ The "Skip Waypoint" function allows you to choose to navigate to a different waypoint (previous or next): Only from the GPS INFO page, with an active route, LONG PRESS the button; the list will appear, press the button to jump to the previous Waypoint or press to jump to the next Waypoint. Press to cancel. ▪ The Digifly AIR also has a shortcut for the “Skip Waypoint” function, from any of the navigation pages. In order to activate it, the "Skip Waypoint Shortcut" parameter (ADVANCED SETUP \ n. 25 SKPW) needs to be activated. Keep in mind that this will change the functions of some buttons: With the parameter set to OFF = Shortcut disabled (default), LONG PRESSING the “ARROW DOWN” button changes the volume level and LONG PRESS of the “OK” button sets the A2 altimeter to zero. However, with the parameter set to ON = Shortcut enabled and, when a route is activated both for competition AIR_Manual_610d_ENG_rev_1.pdf Page 24/104 or XC, LONG PRESSING the “ARROW DOWN” and “OK” buttons, will respectively work as skipping a waypoint back and forward buttons, without having to go to the Info GPS page first. 3.9.9 CREATING A NEW WAYPOINT USING THE CURRENT POSITION (MARK) ▪ "MARK" function: when the GPS acquires a valid position, it is possible to save it in the instrument’s memory. From the GPS INFO page LONG PRESS the key; the message "Save Mark ?" is shown, press the key to confirm or the key to cancel. The current position will be saved as a new Waypoint in the User Waypoint list (“WPT USER”) with the format nnMaaa (aaa= altitude GPS in tens of meters) 3.9.10 NAVIGATION TO “HOME” WAYPOINT (GOTO HOME) ▪ Available only on the GPS INFO page, it ensures that the instrument guides us back to the point where we activated this function from. It is particularly useful, for example, when flying at a new site without any waypoints and want to be guided to the official landing zone (LZ). In this case, it is necessary to go to the LZ and activate this function there. ▪ How to activate the "GOTO HOME" function: from the GPS INFO page, with valid GPS position, LONG PRESS the key, the message "Activate Home Wpt ?" is shown, press the key to confirm or to cancel. Note: if navigation has been previously activated, it is necessary to deactivate it first: from the GPS INFO page LONG PRESS the key, the message " Clear Nav ?" is shown, press the key to confirm or to cancel. The "GOTO HOME" function creates a landing waypoint in the User Waypoint list (“WPT USER”) with the current position data “HOMaaa” (aaa = GPS altitude in tens of meters) and with the icon "A" (Airfield), at the same time, it activates the navigation to it (GOTO). 3.9.11 DEACTIVATING THE CURRENT NAVIGATION (CLEAR NAV) ▪ CLEAR NAV function: to disable the active navigation, LONG PRESS the button, the "Clear Nav ?" message will appear, confirm with the button or press to cancel. 3.9.12 DATE & TIME ▪ Date and current time are automatically updated with GPS data when you start the instrument and will continue updating. ▪ To set time zone you are in, go to: MAIN SETUP \ n. 7 UTCO. AIR_Manual_610d_ENG_rev_1.pdf Page 25/104 4 MAIN FUNCTIONS 4.1 ALTIMETERS ▪ The Digifly AIR features 9 different altimeters: ALT 1, ALT 2, ALT 3, ALT QNE, ALT FL, ALT GPS, ALT H1, ALT HA, and ALT AGL. - ALT 1 (A1) : Barometric altimeter - ALT 2 (A2) : A2 Altimeter - ALT 3 (A3) : Gain during the current thermal - ALT QNE (QE) : QNE Standard Pressure Altitude. Barometric height recorded in your tracklog. - ALT FL (FL) : Flight Level Height Barometric Altimeter referring to the standard pressure in flight levels (hundreds of feet). - ALT GPS (AG) : GPS Altimeter - ALT H1 (H1) : Estimated height over the cylinder of the current WP - ALT HA (HA) : Estimated height relative to goal cylinder, line, etc. - ALT AGL (HG) : Height above ground level with map (see 4.1.1 and 6.17.1) 4.1.1 AGL ALTIMETER ▪ The AGL altimeter, shows the height above ground, (AGL = Above Ground Level). To activate the AGL altimeter, you must have a microSD card with the *.dgm map files of the area you will be flying -created using AirTools- in your Digifly and that the “Elevation Mode” parameter (MAIN SETUP \ n. 19 ELVM), is set to either 1, 2 or 3. A detailed description on how to create a map and how to set the map parameters see section 6.17.1. 4.1.2 ALTIMETERS’ SETTINGS ▪ Graphic Altimeter : digital value of A1 altimeter is integrated with the graphic scrolling altimeter. With a friendly scale and numeric indications every 500 mt/ft embedded into an angular graphic view making the numbers more readable. There is also a simple graduated scale for meters in the hundreds. 4.1.3 ALTIMETERS’ SETTINGS ▪ Go to the “ALTIMETERS” menu and select which altimeter you want to adjust (A1 or A2). Important: while the recorder is activated is not possible to adjust the A1 Altimeter. ▪ Synchronizing the A1 Altimeter with the altitude provided by GPS data: If the “A1-GPS sync.” is enabled, (MAIN SETUP \ n. 39 A1SY default= ON), you are not yet moving (in flight) and have not manually set the A1 altimeter, this altimeter will automatically synchronize with the GPS data. To manually synchronize the A1 altimeter with the altitude data from the GPS, press the button. This may only be done when the instrument has acquired GPS coverage, if you are not moving and if the A1SY parameter is set to ON. Once the flight recorder has started, this synchronization is no longer possible. AIR_Manual_610d_ENG_rev_1.pdf Page 26/104 ▪ The A2 Altimeter is used for general purposes. To reset it LONG PRESS the key. Note that with the “Skip Waypoint” shortcut parameter activated ADVANCED SETUP \ n. 25 SKPW=ON) the “OK” button will have a different function: it will take you to the next waypoint on your route and will no longer zero the A2 altimeter. ▪ With the parameter MAIN SETUP \ n. 25 A2AU=ON, the AIR will automatically set the Altimeter 2 to zero, right after launch. ▪ The A3 Altimeter is automatically reset when you start thermalling. ▪ The altimeters can be shown in meters (mt) or feet (ft), to set up, go to: MAIN SETUP \ n. 13 U-AL. 4.1.4 MAXIMUM ALTITUDE ALARM ▪ This parameter (MAIN SETUP \ n. 40 A1AL) will notify you when you reach the set altitude; the alarm will be reset once you go back down below the set threshold by 10m (33ft). ▪ It ranges from 0 to 9,000ft (approx.. 29,500ft) and default setting is 0. Set to 0, the alarm is off. AIR_Manual_610d_ENG_rev_1.pdf Page 27/104 4.2 VARIOMETERS 4.2.1 11-SENSORS VARIOMETER WITH SELF - ADAPTIVE SENSITIVITY ▪ It's a revolutionary digital system designed by Digifly, based on a sophisticated data acquisition system updated 100 times each second that merges 11 sensors: the atmospheric pressure sensor data with the Pitot tube sensor and the 9 sensors of the inertial data platform (3 accelerometers, 3 magnetometers and 3 gyroscopes). ▪ It is also equipped with self-adaptive sensitivity that auto-modulates the instruments sensitivity according to the air’s conditions: it increases it in weak conditions and decreases in strong conditions or turbulence. This allows to have a vario with high sensitivity and instantaneous response, that is yet fluid and immune to the turbulence while very helpful in weak conditions, thanks to its pre-thermal function. Furthermore, in contrast to varios, based on a pressure sensor only, the Digifly is not affected by false readings due to acceleration. Important Notes: The mathematical method that manages the variometer has been optimized to obtain an excellent response during flights; for this reason, we suggest you try or compare it flying and not on the ground. ▪ Even though the system is totally automated it is possible to manually force the values of some filters: Parameter VARIOMETER SETUP \ n. 15 RVAR, ranges from 1 (minimum reactivity) to 20 (maximum reactivity); default 10. 4.2.2 DIGITAL VARIO ▪ Shows instant climbing or descending values in a range of +/- 25 m/s in digital format +/- 5,000 fpm. 4.2.3 ANALOGICAL VARIO ▪ Indicates the instant vario values; it is displayed by the analogical bar indicator on the left of the screen that shows the sink or climb rate within a +/- 5 m/s range, +/- 500 fpm range. 4.2.4 INTEGRATED (AVERAGE) VARIO ▪ The right-hand bar shows the integrated vario values; the average of the instant vario during X amount of time (this bar can be changed to the value of the net vario, see section 4.2.6). ▪ It can be used to monitor the progression of your climb to see if it is getting better or worse. For example, if the integrated vario value is higher than the instant vario, it means that the climb was previously stronger; it can be used, therefore, to better core the thermal. ▪ The averaging time (integration time) can be set with VARIOMETER SETUP \ n. 16 INTE, ranging from 5 to 60 seconds. 4.2.5 NET VARIO (WITH OPTIONAL PITOT TUBE) ▪ The bar on the right hand, analogically indicates the climb/descent rate values of the air mass around you in a +/- 5m/s (approx. 1,000fpm) range. It can also be set to display the average vario values instead (see 4.2.6). ▪ When the netto vario is being displayed, the icon “NET” will show on the right-hand bar. ▪ N.B. In order to use this function, you must have a Digifly AIR with Pitot Tube option and that the tube is installed on the instrument; also, you need to have the Polar coefficients to be programmed in your instrument (for example, you have Polar 1: ADVANCED SETUP \ n. 11-12-13 P1A-P1B-P1C) and set the Polar parameter to use the values stored for Polar 1 (for example, Polar 1: ADVANCED SETUP \ n. 10 POLA=1). AIR_Manual_610d_ENG_rev_1.pdf Page 28/104 4.2.6 INTEGRATED VARIO / NET VARIO AUTOMATIC SWITCH ▪ You can change the vario’s indicators layout using VARIOMETER SETUP \ n. 17 DSEL : 0 = (default), the right-side analog bar shows the average vario and the digital indicator shows the instant vario. 1 = right-side analog bar and digital indicator always show average vario values. 2 = right-side analog bar and digital indicator always show net vario values. 3 = right-side analog bar and digital indicator change depending on effective flight conditions: when you are gliding, the right-side analog bar and the digital indicator both show net values and, when you are thermalling, the right-side analog bar shows the average vario values and the digital indicator shows the instant vario values. 4 = right-side analog bar and digital indicator change depending on effective flight conditions: when you are gliding the right-side analog bar and the digital indicator both show net values, when you are thermalling, the right-side analog bar and the digital indicator both show average vario values. ▪ When the net vario value is shown, the “NET” icon will appear vertically on the right bar. ▪ Thermalling mode / Gliding mode: it switches to “Thermalling” mode when it feels a new thermal for more than x seconds (VARIOMETER SETUP \ n. 22 THET) default 2 seconds and you make a turn to fly into it; it switches to “Gliding” mode when you fly “straight” for more than x seconds defined in VARIOMETER SETUP \ n. 21 CRUT); default =15 seconds. 4.2.7 McCREADY (WITH OPTIONAL PITOT TUBE)

▪ The McCready value is the average lift value of the last “nn” minutes in thermal ▪ To adjust the average lift time: ADVANCED SETUP \ n. 20 MCRA. (default: 10min) ▪ N.B. In order to be able to use this function, you must have the Digifly AIR with Pitot Tube and have the tube installed in your instrument; also you need to have the Polar data programmed (for example, Polar 1: ADVANCED SETUP \ n. 11-12-13 P1A-P1B P1C) and that the Polar parameter itself is enabled to work with the values you have programmed (for example, Polar 1: ADVANCED SETUP \ n. 10 POLA=1). 4.2.8 EQUIVALENT McCREADY (WITH OPTIONAL PITOT TUBE) Equivalent McCready McCready

▪ This value indicates the Equivalent McCready value: this is the McCready value, considering the current airspeed as the optimal speed. ▪ The equivalent McCready, based on the glider’s polar, the sink rate and the current airspeed (IAS), indicates in real time at which true McCready value we are flying compared to the optimal speed. When this value matches the one estimated in the thermal, this means that the current airspeed (IAS) matches the optimal speed (see “Speed to Fly” section 4.3.1). ▪ To set the reaction time of the Equivalent McCready indicator go to: ADVANCED SETUP \ n. 21 MCRE. ▪ N.B. In order to be able to use this function, you must have the Digifly AIR with Pitot Tube and have the tube installed in your instrument; also you need to have the Polar data programmed (for example, Polar 1: ADVANCED SETUP \ n. 11-12-13 P1A-P1B-P1C) and that the Polar parameter itself is enabled to work with the values you have programmed (for example, Polar 1: ADVANCED SETUP \ n. 10 POLA=1). AIR_Manual_610d_ENG_rev_1.pdf Page 29/104 4.2.9 TOTAL ENERGY COMPENSATION (WITH OPTIONAL PITOT TUBE) ▪ To use this function, it is necessary to have the optional Pitot tube installed. ▪ Generally, a variometer works as follows: it feels the atmospheric pressure change rate considering it as an altitude change, but, if during the flight the pilot slows the glider (and even more so if done quickly), there is a real change of pressure, so a vario ‘without compensation’, records it as a climb, but this variation is caused by a change of speed (kinetic energy) and not due to a true thermal. ▪ With the Total Energy Compensation function, the part of the climb due to the change in velocity is ignored, allowing you to identify the “real” thermals. ▪ To properly set the TOTAL ENERGY compensation values, you need the following parameters: o "Total Energy Compensation Mode" (VARIOMETER SETUP \ n. 18 TECM) : OFF = T.E.C. off (default), ON = T.E.C. is calculated during glide only, FUL= T.E.C. is calculated both during glide and in thermals. o “Total Energy Compensation” (VARIOMETER SETUP \ n. 19 TEC), to set this percentage correctly, you should fly in calm air conditions and slow down as if you were entering a thermal. If the vario shows a change in lift, you have to increase the total energy compensation value, until the change in velocity is no longer recorded as lift; a typical value for hang gliders is 65. o "Total Energy Compensation Average" (VARIOMETER SETUP \ n. 20 TECA): it is the average applied to the total energy component, the range goes form 1 (fast) to 99 (slow); default 80. AIR_Manual_610d_ENG_rev_1.pdf Page 30/104 4.2.10 ACOUSTIC VARIO ▪ The acoustic vario represents the instantaneous values of the vario with a modulated acoustic tone. ▪ LONG PRESSING the key while on any page (except Info GPS) changes the vario volume (3 settings): “HIGH”, “OFF” & “LOW”. The chosen volume is shown by the ‘loudspeaker’ icon on the bottom left side of the display. Please note that if the SKPW (ADVANCED SETUP \ n. 25 SKPW) parameter is ON, the function of LONG PRESSING the “arrow down” button, while flying with an active route will skip to the next waypoint and not adjust the volume; therefore, make sure you set the volume level before activating the route. Remember that when you turn your Digifly AIR on, it checks the volume of the acoustic vario and, if it happens to be turned off, it will immediately turn it up to HIGH. ▪ To set the sound’s threshold level to indicate lift, go to: VARIOMETER SETUP \ n. 1 V.UP; for the sink’s threshold, go to: VARIOMETER SETUP \ n. 3 V.DN. ∙ New Acoustic Vario and New Pre-Configured Sound Profiles The new acoustic vario has been rendered more flexible and more powerful, capable of emulating any type of sound; this function is very important because it allows a pilot coming from any other instrument brand to set up the acoustic vario so that it will have the same sound profile to which he/she was used to. For example, selecting PROF=DG3, acoustic vario will sound like a Bräuniger / Flytec vario. Acoustic Vario Parameters: o VARIOMETER SETUP \ n. 4 DYNH “Enable Dynamic Frequency”: OFF=disabled, ON=enabled (default) Note: It will apply to every sound profile. o VARIOMETER SETUP \ n. 5 DUMP “Dynamic Frequency Average” : from 1 to 15= (default 15) 1=no average, 15=max. average. Remember: this parameter only works if the DYNH parameters is ON and is set up according to your own personal taste, every time a different sound profile is selected: It is already a compromis between response rate and fluidity: very low values will produce quite a reactive sound, but it will make the “piano” effect with abrupt note changes and with very high values, the sound will be a lot more fluid, but it my lag on the response rate side Note: It applies to every sound profile. o VARIOMETER SETUP \ n. 6 PTMD “Pre-Thermal Mode”: 0=pre-thermal sound during glide only (default), 1= pre-thermal sound during both thermal and glide. Note: In previous firmware versions, this function could be enabled using the Variometer Setup parameter AUTV set to FUL, in this version, the AUTV parameter is limited to ON/OFF (setting the autovario to on or off). Note: It applies to all sound profiles. o VARIOMETER SETUP \ n. 7 PROF : “Acoustic Vario Profile”: SFT, STD, FAS, US1, US2, MAN, DG1, DG2 (default), DG3, DG4 The following preset sound profiles were added to this firmware version: DG1, DG2, DG3, DG4 AIR_Manual_610d_ENG_rev_1.pdf Page 31/104 o DG1: this sound profile corresponds to the previous default sound profile on firmware 506a. Note: The suggested initial settings for this profile are: o DYNH=OFF o DUMP=15 o PTMD=0 o PROF=DG1 o RVAR=16 o DG2: (default) new Digifly official sound profile. Note: The suggested initial settings for this profile are: o DYNH=ON o DUMP=15 o PTMD=0 o PROF=DG2 o RVAR=5 o DG3: sound profile equivalent to the Bräuniger / Flytec standard sound. Note: The suggested initial settings for this profile are: o DYNH=ON o DUMP=15 o PTMD=0 o PROF=DG3 o RVAR=5 o DG4: Equivalent Bräuniger / Flytec slightly more “aggressive” sound profile. Note: The suggested initial settings for this profile are: o DYNH=ON o DUMP=15 o PTMD=0 o PROF=DG4 o RVAR=5 If the VARIOMETER SETUP \ n. 7 PROF=MAN the following parameters will be enabled; otherwise, they are irrelevant: o VARIOMETER SETUP \ n. 8 UPHZ: basic climb frequency: 400…..1400 Hz (500 Hz default) o VARIOMETER SETUP \ n. 9 MODH: climb modulation frequency: 1….25 Hz (14 Hz default) Hz/10cm o VARIOMETER SETUP \ n. 10 CURH: climb curve selection frequency: 1…4 (2 default) o VARIOMETER SETUP \ n. 11 TONB: base ton time: 100….1000 mS (400 mS default) o VARIOMETER SETUP \ n. 12 TOFB: base toff time: 0….1000 mS (300 mS default) (0=continuous sound) o VARIOMETER SETUP \ n. 13 PITC: climb cadence curve selection: 0….10 (2 default) o VARIOMETER SETUP \ n. 14 DWHZ: basic sink frequency: 350…..1000 Hz (400 Hz default) Note: these default values (from UPHZ to DWHZ) are identical to those preset for the DG2 sound profile. AIR_Manual_610d_ENG_rev_1.pdf Page 32/104 ▪ Auto-silence (VARIOMETER SETUP \ n. 26 AUTV): “ON” by default, it activates the acoustic vario only after takeoff and stops it 60 seconds after landing. 4.2.11 ACOUSTIC VARIO PRE-THERMAL TONE ▪ If activated, an acoustic signal with a tone and modulation significantly different of the acoustic vario, indicates that we are near a thermal (the instantaneous sink rate is better of the glider’s minimum sink rate, therefore indicating an area of slightly climbing air). To set the pre-thermal sound’s threshold go to: VARIOMETER SETUP \ n. 2 V.PT; value from 0,00 to 1,50 m/s and the suggested value is 0,50 m/s. 4.2.12 VARIO SIMULATOR ▪ For a perfect tuning of the acoustic vario, without flying, it is possible to set the ‘Vario Simulator’ mode, setting the VARIOMETER SETUP \ n. 25 SIMV parameter to “ON” and VARIOMETER SETUP \ n. 26 AUTV to “OFF”. Then exit from menu and use the arrow keys to set the preferred vario sound. To deactivate the simulator set SIMV to “OFF” and AUTV back to “ON”. Note: for safety reasons the simulator is automatically deactivated when the instrument power on. AIR_Manual_610d_ENG_rev_1.pdf Page 33/104 4.3 AIRSPEED (WITH OPTIONAL PITOT TUBE) ▪ This sensor measures the glider’s airspeed. ▪ This function is available only with the Pitot tube sensor module (optional). The tube will have to be inserted in the specific housing hole located on the instrument’s top and the parameter ADVANCED SETUP \ n. 1 PITO has to be set on the desired value: IAS (Indicated Airspeed) or TAS (True Airspeed). ▪ It is possible to set the speed’s unit of measure to km/h or mph using the parameter MAIN SETUP \ n. 14 U-SP ▪ The minimum speed indication is 18 km/h, 11 mph. 4.3.1 SPEED TO FLY (WITH OPTIONAL PITOT TUBE) ▪ Speed to Fly (STF) is the best anemometric speed to obtain the best glide ratio; this value depends on performance of your glider as well as vertical and horizontal airflow. In calm air, the optimum flying speed is the same as the best glide speed (point B). ▪ The diagram shows different values of speed to fly related to different flight conditions ▪ The X-axis shows horizontal speed; the Y-axis shows sink rate. With headwind or sink conditions, the best glide speed increases. In order to find the optimum speed to fly value in sink conditions, the sink rate of the air is added to the polar of your glider, drawing a new polar and a new tangent line from the initial point of axes. The new tangent (point D) meets the polar at the point giving a higher optimum flying speed VD. ▪ To fly at the correct “STF”, adjust your flying speed “IAS” to match the STF indicator (triangle symbol) with the value on the optimal anemometric speed. Speed to fly

▪ N.B. In order to be able to use this function, you must have the Digifly AIR with Pitot Tube and have the tube installed in your instrument; also you need to have the Polar data programmed (for example, Polar 1: ADVANCED SETUP \ n. 11- 12-13 P1A-P1B-P1C) and that the Polar parameter itself is enabled to work with the values you have programmed (for example, Polar 1: ADVANCED SETUP \ n. 10 POLA=1).

AIR_Manual_610d_ENG_rev_1.pdf Page 34/104 4.3.2 ACOUSTIC McCREADY (WITH OPTIONAL PITOT TUBE) ∙ Conditions for setting up and turning the McCready sound on: o McCready sound enabled: ADVANCED SETUP \ n. 22 MCRS=1 o Pitot enabled: ADVANCED SETUP \ n. 1 PITO=IAS or TAS o Polar enabled: ADVANCED SETUP \ n. 10 POLA=P-1 or P-2 or P-3 o The instrument must NOT be on the “Info GPS” page (while on this page, long pressing the “M” button will create a “mark gps” point) o The instrument must NOT be on the “Map” page (while on this page, long pressing the “M” button will access map options) o The instrument must be on a page that displays the “Analog Vario Bargraph” o The graphic Equivalent McCready indicator ranges from 0,0m/s and up o Instant vario in sink o “Glide” flight mode o Long press the “M” button (the Digifly will beep twice, to confirm that the acoustic McCready is now on) Note: Once turned on and while on glide, the acoustic McCready will emit a sound to let you know that you are in sink, regardless the page you are on. You will not mistake the Equivalen McCready and the Pre-Thermal sounds because when the acoustic McCready is enabled (MCRS=1), the Pre-Thermal and Sink Alarms are disabled. ∙ Conditions to Turn the Acoustic McCready Off: o The instrument must NOT be on the “Info GPS” page (while on this page, long pressing the “M” button will create a “mark gps” point) o The instrument must NOT be on the “Map” page (while on this page, long pressing the “M” button will access map options) o Long press the “M” button (the Digifly will beep once, to confirm that the acoustic McCready is now off) Note: the acoustic McCready will also be automatically disabled every time the instrument is turned on and every time you access the MENU page. ∙ Example: o Required setting: ADVANCED SETUP \ n. 22 MCRS=1, ADVANCED SETUP \ n. 1 PITO=IAS (or TAS), ADVANCED SETUP \ n. 10 POLA = P-1 (or P2 or P3). o Instrument on pg 8 XC Glide (example); the Standard pg 8 has the analog graphic vario with the Equivalent McCready). o Flying on “Glide” mode (which means that you are on a somewhat straight course for at least 15 seconds). o Vario in sink (for example flying at -0.2m/s, approx. -40fpm). o Adjust the gliding speed until the graphic Equivalent McCready indicator reaches the desired value (for example, +2.5m/s, approx. 500fpm). o You long press the “M” button to turn the acoustic McCready on (you will hear a confirmation double beep) and saves the current Equivalent McCready as the target McCready value to maintain during glide. o The target McCready range is: 0m/s … +10m/s. AIR_Manual_610d_ENG_rev_1.pdf Page 35/104 o From this point on, when gliding and in sink, you will hear a pulsing sound with a frequency that is proportional to the deviation of the current Equivalent McCready regarding the target Equivalent McCready. The sound will be emitted only when the deviation is higher than +/-0.3m/s, approx. +/-60fpm (quiet zone or dead band). o To turn the acoustic McCready off, simply long press the “M” button again (a single beep will confirm your input) 4.3.3 SPEED DIFFERENCE (WITH OPTIONAL PITOT TUBE) ∙ The “Speed Difference Enable” (ADVANCED SETUP \ n. 2 SDIF) parameter = ON displays the head wind component (=Ground Speed – Anemometric Speed), on the digital indicator on the bottom of the combined speed instrument, instead of the Ground Speed value. A negative value indicates headwind 4.3.4 STALL ALARM (WITH OPTIONAL PITOT TUBE) ▪ The Stall Alarm is activated setting the parameter MAIN SETUP \ n. 41 STAL with the desired speed. It ranges from 0 to 150km/h (default setting: 0km/h). An alarm will sound as soon as you reach a speed below the set speed. The default setting of 0km/h keeps the alarm off. 4.3.5 AIRSPEED CALIBRATION (WITH OPTIONAL PITOT TUBE) ∙ Pitot tube sensor offset calibration It is possible to calibrate the Pitot tube sensor offset corresponding to 0 km/h : a) turn the instrument on, in a place where you don’t have any wind (preferably indoors). b) write down the value of the sensor’s number visible on PAGE 11 (AHRS) beside the km IAS indicator. c) use this number to set the ADVANCED SETUP \ n. 3 OFSP parameter. This parameter can only be modified directly using the menu on the AIR instrument and not using the AirTools software. Warning : If used incorrectly, this feature will render your airspeed indicator less accurate. ▪ Pitot tube sensor span calibration It is possible to perform a fine tuning of the airspeed full scale value using the ADVANCED SETUP \ n. 4 KIAS parameter that indicates the airspeed correction value (100%=no correction, 110%=increase, 90%=decrease). This parameter can only be modified directly using the menu on the AIR instrument and not using the AirTools software. Warning : If used incorrectly, this feature will render your airspeed indicator less accurate. AIR_Manual_610d_ENG_rev_1.pdf Page 36/104 4.4 POLAR (WITH OPTIONAL PITOT TUBE) ▪ A polar curve (see figure below) is the graph of your glider’s sink rate over its speed range. ▪ S is the glider’s stall speed (on the left) and T is the glider’s max speed (on the right). ▪ On the graph, you can also see three pairs of relative speed readings and sink rates. The graph shows at point A, the lowest sink rate achieved at the top of the curve; therefore, Sink A is the minimum sink rate and VA is the speed at which this is achieved. ▪ The glide ratio is the ratio between the glider’s horizontal speed and its sink rate. To find the best glide rate on the graph, it is necessary to draw a straight line from the origin of the graph (point O) tangent to the curve. ▪ The intersection of the tangent with the curve (point B) shows the speed to fly (VB) to achieve the best glide, where you are in B sink; so, your best glide ratio is VB / Sink B. ▪ On your Digifly AIR you can insert three different polar curves using the parameters in ADVANCED SETUP \ n. 11 - 19 PxA / PxB / PxC where Px is the polar 1, 2 or 3 and A, B and C are the ka-kb-kc specific values used by the Digifly AIR to define the polar curve. They must be calculated with the “Curve Editor” a special function within the AirTools program: o Open the AirTools program on your computer, go to the “Configurations” tab, then to “Advanced Setup” and on the P1, P2 or P3 parameters line, next to the factory polar values, you will see a small box with two dots. o Click on the box to open the Polar Curve Editor. Use your polar curve, input the speed and sink values. o Click on the “calculate” button to obtain the ka, kb and kc values that you will then manually set in your AIR. Note that if you want to upload these values to the AIR using the AirTools on your computer, you should first download your parameters, calculate the polar values ka, kb and kc and then upload the entire parameters file. You cannot upload one separate parameter. ▪ To choose which polar to use, go to (ADVANCED SETUP \ n. 10 POLA). ▪ If this parameter (ADVANCED SETUP \ n. 10 POLA) is set to “OFF”, all the information relating to McCready, McCready Equivalent, and Net Vario are not displayed on the instrument. ▪ On the instrument, there are three preloaded polar curves, (2 for hang gliders and 1 for paragliders); using the Digifly AirTools software, you can see the values of the three default polar curves and set your own. ▪ We suggest that you insert your own polar curve data which best reflects the actual performance of your glider. ▪ If one of the polar curves is active, it will be displayed on the top of Standard PAGE 11 AHRS. Its layout is: o ka, kb, kc coefficients (calculated with the AirTools Calculator) o Best efficiency value (L/D max eff) o Airspeed in km/h at max. efficiency o Descending rate at max. efficiency (m/s max eff) o Minimum sink rate and its corresponding airspeed AIR_Manual_610d_ENG_rev_1.pdf Page 37/104 4.5 BAROMETER ▪ The barometer displays the atmospheric pressure in millibar. ▪ It is possible to adjust its calibration with the ADVANCED SETUP \ n. 5 KBAR parameter. ▪ This parameter can only be modified directly using the menu on the AIR instrument and not using the AirTools software. ▪ Important: when the recorder is activated or the instrument detects movements, it is not possible to change this parameter. ▪ Warning : incorrect adjustment of this parameter will make the barometric altimeters less accurate 4.6 TIME ▪ The current time (RTC or RT) is automatically synchronized with the GPS data when the instrument is turned on and will continue to synchronize automatically throughout your flight. ▪ To set the time zone you are in, go to: MAIN SETUP \ n. 7 UTCO. 4.7 CHRONOGRAPH ▪ The Chronograph CHRONO (CH) is automatically reset to zero when the instrument is turned ON. It will remain at 00:00 until the flight begins and will stop when you land, but it will not immediately go back to 00:00. So, if you were to take off again, without turning your instrument OFF and back ON, the chronometer would continue from where it stopped, without resetting. 4.8 PILOT’S NAME & GLIDER’S INFO ▪ To set the pilot name, glider type and glider ID, go to: MAIN SETUP \ n. 16 PILO, MAIN SETUP \ n. 17 GTYP and MAIN SETUP \ n. 18 GID. AIR_Manual_610d_ENG_rev_1.pdf Page 38/104 5 ADVANCED FUNCTIONS 5.1 MAGNETIC COMPASS (HEADING) ▪ Magnetic compass (HEADING) shows directions related to the magnetic north. It is made with solid state sensors along the 3 axes, ensuring correct functionality even if not fully leveled. 5.2 G-METER ▪ The G-meter is made of solid state G-sensors along the 3 axes; its value (G-METER) shows the number of “G” at which we are subjected (1G = an acceleration of 9.8m/s2 or 32.174ft/s2). 5.3 INERTIAL PLATFORM (AHRS) ▪ The inertial platform (AHRS) produces data regarding space location: pitch, roll and yaw. Made by a data acquisition system with a complex processing algorithm and 9 solid state sensors: 3 accelerometer sensors, 3 magnetometers and 3 gyroscope sensors. ▪ Note : Keep in mind that the position in which you are holding your instrument as you turn it on, will self calibrate the inertial platform. 5.3.1 PITCH ▪ Points out the angle of rotation compared to the lateral axis. 5.3.2 ROLL ▪ Points out the angle of rotation compared to the longitudinal axis. 5.3.3 YAW ▪ Points out the angle of rotation compared to the perpendicular axis. Note: All three values (pitch, roll and yaw) can be found on the "STANDARD” layout of PAGE 11. AIR_Manual_610d_ENG_rev_1.pdf Page 39/104 6 GPS FUNCTIONS 6.1 INTEGRATED GPS RECEIVER WITH 99 CHANNELS ▪ Digifly AIR features an extremely sensitive, and state-of-the-art, integrated GPS receiver with 99 channels. 6.2 GPS STATUS INFORMATION ▪ The GPS status icon has different meanings: o Fixed GPS icon = GPS FIX valid (GPS position available) o Blinking GPS icon = insufficient signal (GPS position NOT yet AVAILABLE) 6.3 GPS SIGNAL QUALITY (HDOP) ▪ The HDOP value represents the weakening of the GPS signal; lower values mean good precision. 6.4 EARTH MODEL USED FOR DISTANCE CALCULATION ▪ The parameter MAIN SETUP \ n. 42 DCAL (Distance Calculation Model), allows you to choose the earth reference model used for distance calculation. When set to FAI, it will use the FAI Sphere model and, when set to WGS, it will use the WGS84 model (default). 6.5 TOLERANCE USED FOR DISTANCE CALCULATION ▪ The parameter MAIN SETUP \ n. 43 DTOL (Distance Calculation Tolerance), allows you to select the tolerance range used in distance calculation. It is a percentage, ranging from 0.0 to 0.5% (default 0.0%). 6.6 LATITUDE & LONGITUDE COORDINATES ▪ The latitude and longitude coordinates are always displayed on the upper part of the INFO GPS page and are referred to the WGS84 map datum. 6.7 LATITUDE & LONGITUDE COORDINATES OPTIONS ▪ Four different coordinate formats are available: DMS = degrees, minutes & seconds (dd° mm’ ss.s) (default) DMM = degrees & minutes (dd° mm.mmm’) UTM Universal Transverse Mercator (utm x, y, zone) DDD = decimal degrees (dd.ddddd) To change the coordinate format DMM, DMS, UTM or DDD, use the ADVANCED SETUP \ n. 24 CORD parameter. ▪ The latitude and longitude coordinates are referred to the WGS84 map datum. 6.8 GPS ALTITUDE ▪ The GPS altitude (“ALT GPS”) is the height above the sea level accordingly to the GPS satellite system. 6.9 GPS GROUND SPEED ▪ The GPS ground speed is the glider’s speed related to the ground (“Gs”). This value is always displayed - analogically and digitally- on instruments that do not have the Integrated Airspeed Sensor (Pitot Tube). AIR_Manual_610d_ENG_rev_1.pdf Page 40/104 6.10 GPS DIRECTION (TRK) ▪ The GPS direction (“TRK”) is the glider’s direction related to the ground. 6.11 GROUND EFFICIENCY (GLIDE RATIO) ▪ It shows the efficiency (glide ratio) related to the ground. ▪ To set the time over which the average efficiency (glide ratio) is calculated, go to: ADVANCED SETUP \ n. 8 EFF. ▪ If “Ground Speed” drops below 2km/h (1.2mph) or the GPS signal is not valid, the indicator shows: “-.--”. ▪ ADVANCED SETUP \ n. 9 EFFA, to set the time to be used to calculate the average efficiency (glide ratio) to be used for the glide calculation to WP (altitude upon arrival, etc.). ▪ The average efficiency value is very important because it is the value used by the glide computer. 6.12 WIND SPEED AND DIRECTION INDICATION USING GPS ▪ The wind speed and its direction are automatically calculated using the GPS info Tracking (“TRK”) and the “Ground Speed (“Gs”). ▪ To determine the wind speed and its direction, you should make a “normal” turn, which has to be neither too tight, nor too wide. It is also important to maintain constant airspeed during the turn. ▪ For an accurate calculation at least a 360º turn must be completed. ▪ This function uses the ADVANCED SETUP \ n. 23 WSEN parameter for the wind calculator sensibility (default 5). ▪ Wind speed and direction are displayed in different ways on the instrument: o On the “Wind Speed” instrument displaying the direction in letters (N, E, SW, etc.); graphically with an arrow and numeric figures (see figure above – left side). o On the “Plotter” instrument in two ways: a) Digitally, on the right side of the instrument, showing the direction in letters and the strength in numbers and b) On the grid, it is displayed graphically with a flag showing the direction it’s coming from (see figure above – center). o On the “Round Compass” instrument it is graphically displayed with a flag showing its direction and strength in numbers, just below the flag (see figure above – right side). AIR_Manual_610d_ENG_rev_1.pdf Page 41/104 6.13 LAST THERMAL POSITION, DISTANCE & HEIGHT INFORMATION ▪ The data: direction “BRG T”, distance “DST T” and altitude gain “A3” are displayed when a thermal is detected. ▪ The thermal’s core position is graphically shown (regarding our current position and in scale) with a “T” inside the Thermal Plotter and in the Thermal Assist instrument as well. Keep in mind that when you use the Circular Compass instrument, the two inner circles also contain the Thermal Assist instrument. ▪ To recognize a thermal, this function uses the VARIOMETER SETUP \ n. 22 THET parameter where the lift’s minimum duration is set (seconds); the AIR is programmed to differentiate a thermal from gliding in a good line. 6.14 THERMAL ASSIST ▪ It consists of a graphic instrument that uses two concentric circles and a round icon (letter “T” for thermal) to help you better center the core, taking into account the possible thermal’s drift. ▪ The center of the circles represents our current position and the “T” is the location of the thermal’s core; therefore, we know where to look for it. ▪ We can also customize the scale of the “Thermal Assist” instrument in order to have a better idea of how far away we are from “T”; when “T” is in the center of the 2 circles, we are in the core! ▪ This instrument can be moved on the screen (using AirPages) with a maximum outer diameter of 128 pixels and 40 as a minimum; default 84 pixels. ▪ This instrument includes the "Thermal Assist Zoom Level" parameter (VARIOMETER SETUP \ n. 24 THEA) from 1 to 20; default is 5 mt/pixel meaning that the first circle has a 100m / 330ft* radius, and the second circle a 200m / 660ft* radius. ▪ Keep in mind that the “Circular Compass” instrument, movable on the screen (using AirPages), includes the “Thermal Assist” instrument as well, which is located on the first two circles. 6.15 THERMAL TUTOR ▪ The thermal tutor is an innovative function capable of helping you center thermals by drawing their track on the “Plotter Instrument” using lines with variable thickness to provide strength information: the thicker the line, the better the climb. You will see a black circle with a “T” showing you the point of maximum climb; this way, finding the core of thermal, becomes very intuitive. ▪ The track on the plotter is drawn with a zoom factor (auto-zoom); each time that you change flight situation, from thermalling to gliding and vice versa. ▪ It switches from gliding mode to thermalling mode when it feels a new thermal for more than x seconds (VARIOMETER SETUP \ n. 22 THET); default=2 seconds and if you make a turn to fly into it. When this happens, the plotter cleans up and zooms to the maximum level of magnification defined by parameter VARIOMETER SETUP \ n. 23 THEZ “Thermal Tutor zoom level”, assigning a scaled value in mt to every pixel on the screen (default 1mt/pixel). ▪ It switches from “thermalling” mode to “gliding” mode when you fly “straight” for more than x seconds defined AIR_Manual_610d_ENG_rev_1.pdf Page 42/104 in VARIOMETER SETUP \ n. 21 CRUT); default =15 seconds. When this happens, the plotter cleans up and the zoom is automatically set on the basis of the calculated distance between the current position and the current waypoint so both can be displayed on the plotter at the same time. 6.16 PLOTTER ▪ The plotter automatically displays different sets of information depending on the different flight situations. The plotter is always oriented to the North (North up) if no navigation is active, otherwise it is always oriented to the center of the current waypoint. ▪ Information that is always displayed during every flight situation: o Aerial position and bearing o Wind direction flag o Absolute wind direction (ex. SE) o Wind strength o Track of the last 40sec with variable width depending on the variometer’s values (i.e. thicker: better lift) o “T” icon (thermal) o Scale indicator showing the plotter’s width in meters ▪ In “thermalling” mode: o The plotter zooms to the maximum level of enlargement defined by parameter VARIOMETER SETUP \ n. 23 THEZ“ Thermal Tutor zoom level”, with a range of 1 to 100 m/pixels; default value is 1 m/pixel, corresponding to 25mt per each plotter’s square. ▪ Information displayed during glide, without any navigation feature active: o The north up symbol “N” The zoom’s value will be fixated at 10 m/pixels, corresponding to 250mt per square. ▪ Information displayed in glide when a navigation feature is activated (Route): o Sketch of the current waypoint o Dashed line connecting the airplane (you) to the optimized point of the cylinder of the current waypoint o Dashed line connecting the optimized point from the current waypoint cylinder to the optimized point of the next waypoint cylinder The zoom’s value is automatically calculated depending on the waypoints’ distance ▪ Information displayed in glide when the GOTO navigation feature is activated: o Waypoint’s sketch o Dashed line connecting the airplane (you) to the center of the waypoint The zoom’s value is automatically calculated depending on the waypoint’s distance. AIR_Manual_610d_ENG_rev_1.pdf Page 43/104 6.17 MAP ▪ The Map instrument enables you to view several graphic information sets (layers) at the same time. ▪ The Map instrument is to be found on page 12, by default. ▪ The Map can be placed on any page (using the Digifly AirPages software) and it can go from 120x120 to 240x240 pixels and any size in between. ▪ It is always “North up” ▪ The zoom is fully automatic depending on the route’s navigation requirements. ▪ The scale is displayed, on the lower right corner: in meters, up to 1,000 (3,300ft), and in Km over 1,000mt. ▪ Map layers: ▪ There are four layers available: Terrain (topography), NAV (Navigation), FAI-Triangle Assistant and Airspace CTR 6.17.1 TERRAIN (first layer): ▪ This layer traces the digital elevation terrain map with 10 different shades of grey. ▪ With your Digifly AIR, you get FREE world wide digital topographic maps! The digital terrain elevation map files are created with the Digifly AirTools free software ▪ In order to view the Terrain Layer (digital elevation of the terrain) you should have previously: a) created the digital terrain elevation map files with AirTools, using the “Maps” tab: o Enter the latitude and longitude (in decimal degrees) of your desired map’s center o Set the radius in km (e.g. 200km) o Click on the “Create map” button. The program may prompt you to accept downloading some extra information from the Digifly website. Accept. o Click on the “Save to file” button to save the new map file in your computer. N.B. The file name must have the xxxxxxxx.dgm format, where “xxxxxxxx” can be up to 8 characters. o Close the AirTools program. o Insert the microSD card into your computer then copy & paste the map file on the microSD. o Remove the microSD from the computer and insert it into your Digifly Air with the instrument turned OFF. AIR_Manual_610d_ENG_rev_1.pdf Page 44/104 Important notes: i) Use only microSD cards formatted FAT32, class 10 with at least 8GB and up to 32GB. ii) Insert the microSD card with the instrument turned OFF then turn it on, holding down the power key, in order to verify that the SD card is working correctly. The possible messages are: “Micro SD: OK / NONE / ERROR!” In case of error, turn the instrument off, remove the card and try it again. Digital elevation map selection is automatic: if AGL altimeter or TERRAIN Layer are enabled, as soon as the GPS acquires coverage, the AIR will do an automatic search among the maps available on the microSD card and it will choose the one matching its current position. If you have created adjacent maps, it will also automatically connect these, even when you are in flight! b) set the “Elevation Mode” parameter MAIN SETUP \ n. 19 ELVM = 2 (suggested setting). It defines displaying or not displaying the topography ELVM=0: (default) = AGL altimeter disabled and Terrain Map layer disabled ELVM=1: AGL altimeter enabled and Terrain Map layer disabled ELVM=2: AGL altimeter enabled and Terrain Map layer enabled showing only elevations above the GPS altitude ELVM=3: AGL altimeter enabled and Terrain Map layer enabled and it shows ALL elevations c) set the parameter "Elevation base height" MAIN SETUP \ n. 20 ELVB : It sets the height basis of the Terrain Map’s grayscale when ELVM is set to 3 (all elevations displayed). In this way, you get the most out of the of 10 shades of gray color range the map uses (each shade is called a “step”), corresponding to 10 elevation contour lines. d) set the parameter "Elevation step" MAIN SETUP\ n. 21 ELVS: It sets the value in meters of each elevation step with a different gray scale of the Terrain Map. From 10 to 1000m (default value 100m). ▪ Terrain Map setting examples: When using the Terrain Map, we can define the minimum height at which the TERRAIN elevations are displayed MAIN SETUP\ n. 20 ELVB and the height corresponding to each individual step MAIN SETUP\ n. 21 ELVS. For example, in the Fiemme Valley (Italy) with the valley floor at 1,000m (approx. 3,300ft) and maximum peaks at 3,250m (approx. 10,700ft) I can set my ELVB height at min=1,000m and ELVS step at =200m and the map will show the contour lines from 1000m up to 3000m. ▪ N.B. The Terrain Elevation Map is not displayed when the map’s side is larger than 100km (62mi), when using a 240x240pixels map, or if larger than 50km (31mi), if using a 120x120 pixel map. ▪ N.B. It is possible to interrupt the Terrain Elevation Map’s drawing by pressing the or buttons. ▪ N.B. The Terrain Elevation Map is not displayed when the Navigation layer is set to “NAV photo task” (see 6.17.2 for more details). AIR_Manual_610d_ENG_rev_1.pdf Page 45/104 6.17.2 NAV (second layer) ▪ To display the NAV Layer (NAVIGATION) on your map, you need to have an active route or navigation to a waypoint. ▪ NAV Layer has three different layouts, switchable by LONG PRESSING the button, when looking at the Map tool: A) "NAV ALL REMAINING WAYPOINTS" (default) displays the remaining waypoints and your current position; the map is built around the waypoints you still need to tag and your current position (plane icon). B) "NAV CURRENT AND NEXT WAYPOINT" displays the current waypoint, the one you are currently going to, the next waypoint after that and your current position: the map is built around the current waypoint, the next one and your current position (plane icon). C) "NAV PHOTO TASK" displays the complete route, from take-off to goal, without your current position: the map is built around all the route’s waypoints, including the start waypoint; notice that your current position (plane icon) will NOT be visible. AIR_Manual_610d_ENG_rev_1.pdf Page 46/104 6.17.3 FAI-TRANGLE ASSISTANT (third layer) ▪ The FAI-Triangle Assistant is enabled setting “ON” the parameter MAIN SETUP\ n. 44 FAIT “FAI-Triangle Assistant” (default OFF) ▪ Note: If you have a map on the current page (see the standard Pg.12) and the FAIT is “ON”, and have the GPS fix, the function of LONG PRESSING the button changes and now opens a FAI-Triangle popup with choice window and timeout of approx. 4sec: o "Press UP to swap": it inverts the possible FAI-Triangle area over the task legs o "Press DOWN to set V1-2": memorizes the current position (fix) on vertices 1 and 2 according to the following logic: - vertex 1 will be set automatically with the fix from take-off - if vertex 1 is valid and vertex 2 has not yet been memorized, then I will set vertex 2 with the current fix - if both vertices 1 and 2 have been memorized, then I will overwrite the vertex closest to my current position with the current fix. o "Press OK to set V3": memorizes the current fix on vertex 3, if and only if both vertices 1 and 2 are valid. o “or Menu to exit": by pressing the button, you will go back to the previous screen without any modifications. ▪ On take-off, the FAI triangle will be re-set and vertex 1 will be automatically memorized using the position of take-off ▪ The possible FAI-Triangle area is drawn if and only if the distance of the base (vertex 1, vertex 2) is at least 2km (1.2mi) ▪ FAI SIZE distance indicator The FAI-Triangle size distance is displayed as a numeric value, in real time, on the “FAI SIZE” “FS” instrument. This instrument has been included in the standard Pg.12 Display logic: o Up until you take off, you will see only dashes (both vertices 1 and 2 are not yet valid) o on take-off, vertex 1 will be automatically set with the fix o after take-off, it will display the distance from take-off (vertex 1) until you manually set vertex 2 o after setting vertex 2 using “Press DOWN to set V1-2”, it will display the distance of the base (from vertex 1 to vertex 2) + the distance between vertex 2 and the fix o after setting vertex 3 using "Press OK to set V3", it will display the distance of the base (from vertex 1 to vertex 2) + the distance between vertex 2 and vertex 3 + the distance between vertex 3 and the fix Note: When the FAI-Triangle assistant is disabled, then the FAI SIZE instrument will always indicate the distance to the take-off AIR_Manual_610d_ENG_rev_1.pdf Page 47/104 6.17.4 AIRSPACE CTR (fourth layer) ▪ This layer displays the airspaces and CTRs on your map. Important: this layer is not displayed when the Navigation layer is set to “NAV photo task” mode (see section 6.17.2). ▪ In order for the Digifly to draw he airspaces and CTRs, you must have previously uploaded the airspace & CTR file to the instrument’s internal memory and have correctly set the following parameters: MAIN SETUP \ n. 22 CTRM " enable CTR mode" = ON , MAIN SETUP \ n. 23 CTRD "CTR distance warning" and MAIN SETUP \ n. 24 CTRH " vertical CTR warning". Detailed instructions for this matter, are found in 6.18 and 6.18.1 below. 6.18 3D AIRSPACE MANAGER (CTR) ▪ The “3D Airspace manager” function has a very important role in air navigation especially concerning safety since it is constantly verifying -in all 3 dimensions- that our distance from the different airspaces is never closer than the safety threshold we have set, both horizontally and vertically. As soon as you pass these set thresholds, an acoustic alarm will sound and your Digifly AIR will post a warning message on your screen. ▪ The “3D Airspace manager” is managed using the following three parameters: CTRM, CTRD and CTRH. A) “CTR Selection Mode” (MAIN SETUP \ n. 22 CTRM) set to OFF (default) totally disables its display and set to ON enables the display of the CTR layers and the proximity alarms. B) "CTR Distance HORIZONTAL Warning" (MAIN SETUP \ n. 23 CTRD) should be set to the desired horizontal distance at which you want your AIR to let you know that you are getting too close to the CTR. Default setting is 400mt/1,312ft (CTRM must be set to ON and the airspace file must be in the instrument for it to work). C) "CTR Vertical Distance Warning" MAIN SETUP \ n. 24 CTRH should be set to the desired vertical distance. Default 400mt/1,312ft (CTRM must be set to ON and airspace file must be in the instrument for it to work). 6.18.1 UPLOAD AND ENABLE AIRSPACE CTRs TO THE DIGIFLY AIR ▪ In order to be able to see the airspaces and CTRs, to activate the distance warning messages and alarms, you need to have previously done the following steps: a) Search and download (Internet) the airspace and CTR files for your flying area in standard OpenAir format.

It also displays the direction towards the nearest point on the cylinder with the icon. 10.4.3 REQUIRED GLIDE RATIO TO CURRENT WAYPOINT ▪ It is the estimated needed glide ratio to reach the current Waypoint's cylinder along the optimized route. 10.4.4 ARRIVAL TIME & TIME TO CURRENT WAYPOINT ▪ "TIM1 (T1)" shows the estimated arrival time to get to current cylinder waypoint along optimized route and "ETIM1 (E1)" shows how much remains until the estimated arrival time. 10.4.5 HSI GRAPHIC NAVIGATION TO CURRENT WAYPOINT ▪ HSI is a graphical navigation tool made by two dashed lines that intersect each other indicating the current WPT and its real height. Flying towards the center of the WPT cylinder, the airplane icon moves right or left of the dashed vertical line in reference to the route and up or down the dashed horizontal line telling us the arrival height to the cylinder, with the current gliding ratio. 10.4.6 DISTANCE & HEIGHT OVER THE ARRIVAL WAYPOINT (GOAL) ▪ DST A (DA): Shows the distance to the goal along the optimized route. ▪ ALT HA (HA): Shows the estimated height above the goal , along the optimized route. This height is calculated using the following data: o ALT A1 : current barometric altitude A1 o DST A : distance to the goal along the optimized route o Altitude of the goal waypoint o Average Efficiency, which is updated in real time while gliding and stored while thermalling, to change the average time (in seconds) modify the ADVANCED SETUP \ n.9 EFFA parameter AIR_Manual_610d_ENG_rev_1.pdf Page 60/104 10.4.7 REQUIRED GLIDE RATIO TO GOAL ▪ It is the estimated needed glide ratio to reach the goal, along the optimized route. 10.4.8 ARRIVAL TIME & TIME TO GOAL ▪ "TIMA (TA)" shows the estimated arrival time to get to the arrival waypoint along optimized route and "ETIM A (EA)" shows how much remains until the estimated arrival time. 10.4.9 CROSS TRACK ERROR (XT) ▪ This instrument displays your lateral deviation regarding the NON-optimized route. Showing your distance from the line joining the centers of the two waypoints (past and current). If you are to the right side of the line, it will be displayed in black over white, if you are to the left side of it, it will be displayed in reverse (white over black). ▪ Remember: when creating your own pages (with AirPages), leave the border of this instrument; otherwise, the reverse function will not work. It will ONLY display black over white (not showing you are flying left of the route). AIR_Manual_610d_ENG_rev_1.pdf Page 61/104 10.5 NAVIGATION TO THE START WAYPOINT (GATE) ▪ The current Waypoint is managed as a Start waypoint only if its parameter Type has the value “SSS” (Start of Speed Section - see 9.5). ▪ The crossing direction of the Start Waypoint line is established by its parameter In/Out : “IN” = Entry start Waypoint (Entry) , “OUT” = Exit Start Waypoint (Exit). (see 9.5). ▪ When the first start gate time is 10 minutes away, a message appears on the screen: "10 MIN TO GO !" followed by a double beep. ▪ When the time to the start gate is 00:00, the “GATE OPENED” message appears on the screen, followed by a double beep, telling the pilot that the gate is open and he can now go through the start waypoint (IN or OUT depending on the selected option). ▪ When you go through the start waypoint before the gate is opened, the value of the distance to the cylinder line is shown in reverse mode (white on black background) so that you know you’re on the other side of the circle. ▪ The instrument guides us constantly towards the border of the “start waypoint”, until it gets crossed correctly when it opens. When this happens the "WP OK" message appears, followed by a bitonal sound. ▪ IN = start validation entering the cylinder OUT = start validation exiting the cylinder. ___________________________________________________________________ ENTRY START GATE ( IN ) EXIT START GATE ( OUT )

AIR_Manual_610d_ENG_rev_1.pdf Page 62/104 10.5.1 STARTING TIME (TSTART) ▪ TSTART: Shows the start gate time. To choose a different start gate time, see section 10.5.5 below. 10.5.2 REMAINING TIME TO START (CSTART) ▪ CSTART (CS): shows time remaining (countdown) until the start gate opens To choose a different start gate time, see section 10.5.5 below. 10.5.3 EXPECTED ARRIVAL TIME TO START LINE (ESTART) ▪ ESTART (ES): Shows the estimated arrival time to the edge of start cylinder, based on the average speed relative to the countdown. If the instrument indicates “00:10" (black on white), it means the pilot will get to the start line with a delay of 10 seconds; if its written “00:15 " in reverse mode (white on black), it means the pilot will get to the start line 15 seconds ahead of time (penalty). 10.5.4 REQUIRED SPEED TO START THE CYLINDER LINE (STS) ▪ STS (SS): shows the required speed to get to the start cylinder line in time for gate opening. 10.5.5 CHOOSING A DIFFERENT START GATE TIME IN A COMPETITION ROUTE ▪ Once the route is activated, all these parameters refer to the first start gate time. If you decide to take a different start (when there are multiple start gates), you need to short press the button once -on any of the navigation pages (it won’t work from the “INFO GPS” page)- in order for the values to update to the new start gate time. Every time you short press the button, you will move one clock forward and, if you are on the last one, you will jump back to the first one. 10.6 SKIP WAYPOINT SHORTCUT ▪ The “Skip Waypoint” function of a route (no shortcut - from “Info GPS” page) is explained on paragraph 3.9.8 ▪ The Digifly AIR also has a shortcut for this function, from any of the navigation pages. In order to activate it, the "Skip Waypoint Shortcut" parameter (ADVANCED SETUP \ n 25 SKPW) needs to be set to ON. Keep in mind that this will change the functions of some buttons: With the parameter set to OFF = Shortcut disabled (default), LONG PRESS the button changes the volume level and LONG PRESS of the button sets the A2 altimeter to zero. However, with the parameter set to ON = Shortcut enabled and, when a route is activated both for competition or XC, LONG PRESS the and buttons, will respectively work as skipping a waypoint back and forward buttons, without having to go to the Info GPS page first. AIR_Manual_610d_ENG_rev_1.pdf Page 63/104 10.7 OPERATION CHECKLIST BEFORE A TASK ▪ Be sure that batteries are fully charged. ▪ Make sure the competition-specific pages (Pg01 to Pg06) are active (see section 3.3) ▪ Ensure the IFLY parameter (MAIN SETUP \ n. 38) is set to CMP = automatically switches between the 6 competition pages (see section 3.2.3) ▪ Verify that parameter A1AL (MAIN SETUP \ n. 40) is set correctly = max. A1 altitude (see section 4.1.4) ▪ Ensure the correct setting of parameter DCAL (MAIN SETUP \ n. 42) = FAI Sphere / WGS84: mathematical model of the earth used by the distance calculator (see section 6.4) ▪ Make sure parameter DTOL is set correctly (MAIN SETUP \ n. 43) = x.x % : tolerance percentage used by the distance calculator (see section 6.5) ▪ Download the waypoints from the competition’s official web site or get them from the scorekeeper. ▪ Upload them to the Digifly Air using AirTools via USB cable (PC, Mac) , GPSDump via USB cable (PC, Mac, Android Smartphone) , GPSDump via Bluetooth (Android Smartphone) or with another Digifly AIR using a microSD memory card and the microSD manager ▪ Edit the route accordingly to the information on the taskboard: o Insert the cylinders’ radii o Set the type of waypoint correctly in the “Type” field, remember to set the Start waypoint to "SSS" (Start of Speed Section – see paragraph 9.5). o Specify whether the waypoint has an Exit or an Entry cylinder around it using the field “In/Out”: "IN" (cross the line as you enter the cylinder) or "OUT" (cross the line as you exit the cylinder). o Insert the start time correctly o For multiple start gates (SG), insert the SG interval and Number of SG. o In the route page verify that the total distance corresponds (“Tot dst m”), it is calculated from the center of the first waypoint to the center of the last waypoint along the standard route (not optimized). ▪ Activate the route : LONG PRESS the key and confirm. Important: when you activate the route, a window with the summary of the most important settings of your route will pop up to allow for a settings check before the competition starts: o Date and local time : check the correct setting of UTCO = time zone + summer or winter time o IFLY = OFF / CMP / XC : current setting of the automatic page switcher “Intellifly” o DTOL = x.x % : tolerance percentage used by the distance calculator o DCAL = FAI Sphere / WGS84 : mathematical model of the earth used by the distance calculator ▪ Set the barometric A1 Altimeter, this is important as it is also used by the glide computer. ▪ Before takeoff, turn your instrument on, with enough time to allow a correct GPS position to be acquired. ▪ After the GPS position has been acquired, check that the time is correct. If necessary, change the time zone setting, otherwise the start time will be wrong. Parameter: MAIN SETUP \ n.7 UTCO AIR_Manual_610d_ENG_rev_1.pdf Page 64/104 11 FLIGHT RECORDER ▪ When the Digifly Air starts the flight recorder, it shows the “REC ON” message and the “rec” icon, on the bottom of the display, starts blinking. The following parameters are continuously recorded: Date and time, latitude, longitude, fix status, barometric altimeter QNE , altimeter GPS, number of satellites, GPS ground speed, anemometer, variometer and barometric A1 altimeter. ▪ The Recorder adds a barometric point to the recorded track even when there may be a temporary gap in GPS coverage (according to the FAI-CIVL Cat 1 regulations). ▪ IMPORTANT: while in menu no data is recorded. 11.1 ACTIVATING / DE-ACTIVATING THE FLIGHT RECORDER ▪ The flight recorder can operate in three different ways: o “AUT”: Automatic flight recorder. o “ALW”: Flight recorder always active o “OFF”: Flight recorder deactivated. 11.1.1 RECORDING MODE: AUTOMATIC START “AUT” ▪ Default setting. The flight recorder starts automatically, MAIN SETUP \ n.3 RECM = AUT ▪ The flight recorder activates automatically when: the GPS position is available and it has detected a takeoff with an altitude variation of at least 0,5m (MAIN SETUP \ n.4 R.DS = 0,5) and Ground Speed (GPS) higher than 6km/h (3.7 mph) for 3 consecutive seconds (MAIN SETUP \ n.5 R.TI = 3). ▪ PRE-RECORDER (according to the FAI-CIVL Cat 1 regulations) When you take off, the recorder will include, at the beginning of the flight log, the 30 trackpoints prior to the take-off (pre-recorder). Before taking off, you need to make sure the recorder has been able to get at least 30 trackpoints (=30 seconds). While the instrument records these 30 points, you will see a black rectangle in place of the recorder’s icon. ▪ The flight recorder is automatically deactivated 60 second after landing or if the instrument is turned off. 11.1.2 RECORDING MODE: ALWAYS ACTIVE “ALW” ▪ To set the "Always Active" record mode, set the MAIN SETUP \ n.3 RECM parameter to “ALW”. The flight recorder is activated once the instrument is turned on and is deactivated when it is turned off. 11.1.3 RECORDING MODE “OFF” ▪ To deactivate the flight recorder set the MAIN SETUP \ n.3 RECM parameter to “OFF” (no data is recorded). AIR_Manual_610d_ENG_rev_1.pdf Page 65/104 11.2 RECORDING RATE ▪ The recorder rate can be adjusted from 1 to 60 seconds, go to: MAIN SETUP \ n.6 RECR). ▪ Setting 1 data point per second, will record over 30 hours of flight data. ▪ Setting 1 data point per minute, will record up to 1800 hours of flight data. ▪ The recorder memory has room for up to 100,000 GPS data points and up to 250 flights. ▪ When you are 100m from a Waypoint, the recorder rate is automatically increased to 1 data point per second. ▪ When the recorder’s memory is full, the oldest flight is automatically deleted by the newest one. ▪ The remaining free memory time and percentage are shown for 2 seconds as the instrument is turned on, or for as long as the power button is pressed when turning the instrument on. ▪ If a single flight fills the whole memory, it is not possible to use the recorder anymore. The “MEM FULL” message appears every time that you try to use it. To activate the flight recorder again, it is necessary to clear the entire recorder memory. To do this: go to MENU \ LOGBOOK LONG PRESS the key and confirm the cancellation of ALL FLIGHTS by pressing the key, or cancel the procedure using the key . 11.3 LOG BOOK MANAGEMENT (LOG BOOK) ▪ To see the recorded flights, select the menu “LOGBOOK”. The list of all the recorded flights will be displayed with their date and take off time. ▪ To see details of each recorded flight, select a flight the press the key. For every flight the following information is displayed: o Take off date and time, flight duration, and total altitude gain. o Max. and min. values for A1 Altimeter and Variometer o Max values for Ground speed GPS and Indicated Airspeed (IAS) ▪ To delete all the flights : from the menu “LOGBOOK LONG PRESS the key and confirm the cancellation of ALL THE FLIGHTS by pressing the key, or cancel the procedure using the key. ▪ It is not possible to delete a single flight. Suggestion: It is a good practice to clear up your flight memory before the start of a competition. You can save your flights on your computer before doing this. 11.4 INTEGRATED IGC FILE ▪ INTEGRATED IGC FILE (formatted according to the FAI-CIVL Cat 1 regulations) Automatically generates an IGC file with G-Record signature directly on the microSD card, in the \IGC folder. If the folder is not yet on the microSD, it will be created automatically. ▪ How to use: Go to Menu \ Logbook, select the desired flight, then LONG PRESS the button. ▪ The help message under “Logbook” will say “long press OK to save IGC” AIR_Manual_610d_ENG_rev_1.pdf Page 66/104 12 ADDITIONAL MEMORY CARD ▪ On the Digifly AIR’s housing, you will find the microSD Class 10 memory card reader slot, with a capacity ranging from 8GB to 32GB formatted FAT32. ▪ To insert a memory card, your instrument must be OFF. Place the card with the label facing the instrument’s keyboard side and insert the card’s connector side in the instrument; to lock the memory card it is necessary to gently press it with your fingernails (or another microSD) until it you hear the typical “locked” click. ▪ To extract the memory card, turn your instrument OFF, press the SD card and let it go, to release it. Warning: Beware that if the card is inserted incorrectly, it could damage the instrument void its warranty. ▪ You will use this card to store the topographic map files, as many as you want, that your AIR will use for the map instrument. With the microSD card containing map files in your AIR, when you turn it on and it acquires GPS signal, the AIR will automatically search those files and select the ones relevant to the place it finds itself in. micro SD slot 12.1 MICRO SD MANAGER ▪ The “MicroSD Manager” enables transferring data from one Digifly AIR to another using a microSD card (e.g. waypoints, routes, pages and sound profiles). ▪ On the Main Menu scroll down then select “microSD Manager” and choose the function you would like to access: Route Import Route Export Wpt Comp Import Wpt Comp Export Wpt User Import Wpt User Export Audio Import Audio Export Page Import Page Export File Explorer Auto Import AIR_Manual_610d_ENG_rev_1.pdf Page 67/104 ▪ The directory structure, created automatically is as follows : \ROUTES (*.TSK) ROUTE-01.TSK … ROUTE-12.TSK \WAYPOINT (*.WPB) WPT-COMP.WPB, WPT-USER.WPB \AUDIO (*.DGA) AUDIO-01.DGA, AUDIO-02.DGA \PAGES (*.PAG) PAGE--01.PAG … PAGE--12.PAG ▪ “File Explorer” function : - Use arrows to highlight a directory, then the button to access it - LONG PRESS the button to return to the main directory - Exit using the button ∙ “Auto Import” (from microSD) function : This function is very helptul to automatically import all the files in the microSD’s \AUTOIMPO folder. For example, it is possible to upload the new help file directly to your instrument, the steps are as follow: o Correctly insert the microSD on your PC/Mac/Smartphone. o Create a folder named \AUTOIMPO and copy the help files you want to upload to the new folder, in this example, it would be the U246_Help_UK_v2_Air610d.CCC o Remove the microSD from your PC/Mac/Smartphone. o Ensure that your Air is turned OFF and the microSD is in the correct posistion before instertin it. o Turn your Air ON, then go to MENU and to the “microSD Manager” function. o Enter the “Auto Import” submenu and press the button. o Once the instrument is done uploading the files, it will automatically return to the “microSD Manager” function. o Exit the menu page and go back to the instrument’s regular pages. AIR_Manual_610d_ENG_rev_1.pdf Page 68/104 13 CONNECTIONS & INTERFACES ▪ It is possible to connect your Digifly AIR-SE and AIR-BT to a PC, Mac, Smartphone, Tablet, PDA, etc. using the provided USB cable. The Digifly AIR-BT allows also the connection via Bluetooth. 13.1 USB CABLE CONNECTION ▪ Connecting to an Android Smartphone via USB cable does not require a driver installation; just use a simple USB-OTG (On-The-Go) adapter. ▪ Instead, in order to use the USB connection with a PC or MAC, the FTDI driver must be installed. ▪ USB cable driver automatic installation Connect the USB cable to the PC/Mac and to the instrument, while connected to the Internet and the operative system will usually download and install the FTDI driver automatically. ▪ USB cable driver manual installation If the automatic installation is not successful, you need to manually install the FTDI driver: o Disconnect the USB cable from the PC/Mac and from the instrument o Download the proper driver installation program accordingly to the PC/Mac in use from digifly.com -> download -> FTDI USB Cable Driver. o Find your computer system on the chart and choose the driver on the far-right column (under comments). o Unzip the downloaded files and run the driver installation program. o Restart your computer and reconnect the USB cable to the computer and to the instrument. ▪ Verify proper installation of the USB driver: o Connect the USB cable to the PC/Mac o For example, from Windows7, go to Start -> Control Panel -> System and Security -> System -> Device Management. o Click on the “+” sign next to "Ports (COM e LPT)". o If the driver is correctly installed, you will see the "USB Serial Port (COM X)" without any yellow indication of error. Note: The ’X’ is the number of the COM port assigned to the computer’s USB. o The driver type is visible with a right click on your mouse over "USB Serial Port" then click on “Properties'”; if the driver is installed it will show “FTDI”. ▪ How to manually reassign the COM port number: o All Digifly software performs the automatic search of the COM port in the range of 1 to 20; a third-party software in most cases requires that the COM port is in the range from 1 to 9. If the COM port assigned by the computer has a higher number it is necessary to manually reassign it: o Connect the USB cable to the PC/Mac o Right click on "USB Serial Port” then click on “Properties'” AIR_Manual_610d_ENG_rev_1.pdf Page 69/104 o Click on "Port settings" then click on “Advanced” o In the "Advanced Settings" window, set the "COM Port Number" with the lowest number (from 1 to 9) among the ports that aren’t already in use, then click "OK" Note: If the value displayed on the "Device Manager" window is still the old one, refresh the display value by closing and reopening this window o Take note of the COM port number, to be used later on to manually set the correct port number of third-party software (e.g. GpsDump). Please note that all Digifly software has automatic COM port number detection (Auto-search) and therefore it does not need this setting. AIR_Manual_610d_ENG_rev_1.pdf Page 70/104 13.2 BLUETOOTH CONNECTION (AIR BT ONLY) ▪ The communication possibilities offered by the fully functional Bluetooth System on the Digifly AIR BT are extraordinary and practical! There are two major lines to use your Bluetooth: 1) Upload and download waypoints and tracklogs between your instrument and an external device using GPS Dump Android version. 2) The second option, which really marks a difference and, once more, shows the quality of this instrument is that the Digifly AIR BT has an integrated Digi-FLYBOX (Telemeter). This feature allows your Digifly AIR BT to send its telemetry (data from its sensors: barometric altitude, GPS altitude, ground speed, IAS speed -with Pitot Tube system-, variometer, GPS position, etc.), in the international NMEA format via Bluetooth or via USB cable, to another device (E-Reader, Smartphone and Tablet) it has previously paired with, so that this data can be used directly by specialized programs such as LK8000, XCSoar, XCTrack, Top Hat, GpsDump, TTLiveTrack24, Flyskyhy. It is possible to communicate also with certain iPhone Apps (ex. Flyskyhy) using "Bluetooth BLE" mode (set the ADVANCED SETUP \ n. 29 BLUT parameter to " BLE”). Note: the "Bluetooth BLE" mode can be activated only on AIR BT instruments with serial numbers 4000 and above. The telemetry can also be used to live track to any server using, for example, GPSDump or TTLiveTrack24 on a Smartphone. This means that the Digifly AIR BT is also a Telemeter and in Digifly we call this the Integrated Digi-FlyBox ; other companies call this function an “Info Box / Data Source / Sensor Box”, but none of these will include an anemometer (Pitot Tube System) like our instrument does. 13.2.1 BLUETOOTH “PAIRING” ▪ The communication via Bluetooth between Digifly AIR-BT and an external device (Smartphone , Tablet and E Reader) is possible only after pairing the two devices, here is how to proceed: 1) On the AIR-BT, set the ADVANCED SETUP \ n. 29 BLUT parameter to "SPP" (Android devices) or to “BLE” (Iphone devices). Note: the "Bluetooth BLE" mode can be activated only on AIR BT instruments with serial numbers 4000 and above 2) Enter the MENU page and go to "AirTools" 3) You will be prompted to choose whether to communicate via USB cable or via Bluetooth with the message "Press OK to link USB, Press DOWN to link BT or Menu to exit", press the key. 4) AIR-BT looks forward to the pairing request from the external device. 5) From the Bluetooth’s control panel of the external device, press the option "Search". 6) A list of available devices is created, select "Digifly Air nnn" (where “nnn” are the last three digits of your instrument’s serial number). 7) When prompted, enter the pairing code of the AIR-BT which is "0000" and then confirm; if the procedure is successful, the external device displays a message confirming that the Digifly AIR BT is paired. ▪ Once the AIR has paired with a device, it is no longer necessary to repeat the pairing process. ▪ In case of problems, press the key on the AIR-BT to exit and try it again. AIR_Manual_610d_ENG_rev_1.pdf Page 71/104 14 SOFTWARE 14.1 AIR MANAGEMENT SOFTWARE ▪ Your Digifly Air uses the Digifly protocol, which enables high speed communication with the applications having it embedded in their interface (e.g. AirTools, AirPages and GpsDump); thanks to this protocol it is possible to remotely access & configure your vario.

It is important! 2) Close all other PC/Mac programs that are running, including the antivirus & firewall. 3) Make sure that the instrument is turned off and connected with the USB cable to your computer. 4) Press and hold the key first and hold it down, then simultaneously press and hold the key and wait until the instrument emits a long acoustic “beep”. Now the instrument is turned on and is in “boot loader mode”, waiting for the firmware upload. Note: the screen will be totally blank at this point. 5) First release the key and then the key. 6) On your PC/Mac run the Digifly’s firmware updating program "AirUpdater". 7) Set the COM Port (“Auto-search”) and the speed (115200) should be automatically set, press the “Start” button, then select the firmware file (e.g. AirBt_506a_Gr_19.hex) and confirm. Note: If you need to upload the same firmware version: right click on the Start button, click on "Force full firmware update" then select the firmware file and confirm. 8) The complete update procedure takes about 10 minutes; once finished, your computer will provide an acoustic and visible message, then the Air instrument will switch off automatically. ▪ Important! If you are unable to update the firmware due to lack of communication, the firmware will still be in the instrument, so forcing the AIR to exit from bootloader mode should be enough. This is done by resetting the instrument: Press the and buttons at the same time for more than 5 seconds; this will force the instrument to turn off and resets it. Turn the instrument back on as usual. This will not erase any data or settings from your instrument.

To restore it, you will need to do a different kind of reset using 3 buttons that will reset the AIR and, at the same time, bring it to bootloader mode: o Press and hold the 3 and keys together. o Wait 5 seconds and then release the key; the instrument emits a long acoustic “beep”. o First release the key and then the key. Now the instrument is turned on and it is in “boot loader mode”, waiting for the firmware upload. Note: the screen will be totally blank at this point. o Resume from step 6) making sure the “Set COM” is on “Auto-search” and “Set speed” on “115200”. AIR_Manual_610d_ENG_rev_1.pdf Page 80/104
