  • Page 7 Quick Start Guide 4. Plan your Flight Plan a flight in 4 easy steps. For more details, see the flight planning chapter. STEP 1 Create new Flight Plan: WingtraPilot will open with the welcome menu. For flying and collecting data, select the first item "Create a new Flight Plan" and follow the interface. You can go back to the welcome menu at any time by pressing the orange Wingtra icon on the top left of the screen.
  • Page 8 Quick Start Guide STEP 2 Set Home: Place WingtraOne at your desired takeoff and landing point. Set Home on WingtraPilot by clicking on the first item on left side (A). If you are connected to WingtraOne, Home is automatically placed to WingtraOne's location. If you plan the flight beforehand in office, you can move it to the place where you intend to takeoff — it will be adjusted to WingtraOne's location once you are on the field. Adjust "transition altitude" and "transition direction" on the right side (C) such that WingtraOne will not collide with any obstacle. WingtraOne will take off, rise to your "transition altitude" above Home, transition into forward flight, fly to the drawn loiter circle, loiter up to the area altitude and start data collection. After finishing data collection, it will fly back to the loiter circle at the altitude of the last area, loiter down to "transition altitude", fly back to the Home point, transition above Home, and land.
  • Page 9 Quick Start Guide STEP 3 Add Area(s): You can add one or more areas that you want to map by clicking on the area item on the left side (A). Choose your desired ground sampling distance (or alternatively, your desired altitude) on the right side (C), and adjust the flight direction and overlaps if needed. Make sure you selected the correct camera model. Move the corners (minus signs) and add additional corners until you draw the area that you want to map. STEP 4 Review the Flight Plan: Review the terrain thoroughly: make sure WingtraOne will not collide with any obstacles. Also check that your flight does not violate laws or WingtraOne market-entry restrictions. 5. (Optional) Adjust Camera Settings In most cases, the default camera settings should be fine. Use the following procedure to change settings: 1. Power WingtraOne, if not done yet. 2. Manually turn on the QX1 by clicking the On/Off button on the camera. If you fly an RX1R2 it is already turned on. Adjust settings via Sony'a Play Memories app (QX1) or via the camera itself (RX1), see camera chapter for details.
  • Page 10 Quick Start Guide 4. To save the settings you have to manually turn off the camera by switching the on/off button. In case of the RX1 make sure to turn on the camera afterwards again. 6. Go through Preflight Checks Go through the preflight checklist within WingtraPilot before you start the flight. If any of the preflight checks fails (e.g. sensor failure), the respective preflight check turns red. Starting a flight is possible only once all checks have been completed successfully. For a detailed description of all preflight checks and troubleshooting advice, see the preflight checklist section. WingtraOne takes a series of test pictures during preflight procedure to ensure the camera is working. For QX1, check if you can hear the camera's shutter, for RX1R2 open the cover and watch on screen if pictures are taken. Wait for the audio-feedback "Test pictures are taken" before taking off. Fly & Collect Images 7. Start the Flight Make sure that no people are closer than 5 meters to WingtraOne. Take off by clicking onto "Start Flight" and moving the slider slowly from left to right. Always repower WingtraOne between flights. Do not take off again after landing without powering off and repowering WingtraOne. 8. Flight Observation...
  • Page 11 Quick Start Guide Always observe WingtraOne during flight. A: Information about remaining battery and GPS quality. B: Change display options (center map, change map tiles) C: Options to take over (after clicking a button, you have to confirm with a slider). Engage "Return-to-Home" to bring back WingtraOne and let it land autonomously. WingtraOne will automatically engage Return-to-Home in case of low battery, geofence violation, or if both telemetry and RC connection are lost. For further details, see the chapters about your options to interact and failsafe scenarios. Only use emergency stop in real emergency cases. Emergency stop will kill the motors and make WingtraOne spiral down without any control. There is no way to regain control on emergency stop. Process your Images 9. Geotag the Images The collected images are saved on the SD card in the camera without assigned GPS information (geotags). To assign geotags to the images, you need to perform the following 3 steps. Tag your images always right after flight. STEP 1: Download the Geotags After landing, WingtraPilot will start downloading the geotags automatically. If the download fails, click on "Retry" and walk towards WingtraOne to get better connection.
  • Page 12 Quick Start Guide STEP 2: Geotag Images on the Tablet After the download is successful, click on "Geotag Images". Then power off WingtraOne, get SD card from the camera and insert the SD card to your tablet. Select the image directory on the SD card that contains your images, and click "Start Tagging". Be patient! Geotagging images can take several minutes. The geotags will be directly saved to the EXIF metadata of the images. You can plan the next flight in parallel and continue collecting more data, while geotagging takes place in the background. STEP 3: Inspect / Save Images To inspect your images, open the MyFiles App, navigate to SDcard/DCIM/ and into your project folder. Open an image in the /Tagged subfolder and select "Gallery" as image viewer. The SD card should provide enough space for several flights (up to 3000-4000 JPEG images), you can continue flying directly or insert the SD card on a laptop and save the data after every flight. 10. Use the Geotagged Images in your Postprocessing Toolchain Copy the geotagged images from the SD card to your computer and use them with your favorite postprocessing toolchain. Always use the images from the /Tagged subfolder.

  • Page 17 Camera not connect). The recommended settings differ depending on the used lens, see below. For more information about the camera see the official Sony Documentation. QX1 with 16mm or 20mm Pancake Lens Light Camera Shutter Aperture, Image Conditions Program Mode Speed [s] f-Number Settings Quality default Shutter Priority 1/2000 auto 1000 fine The default settings give good results in large range of light conditions. In case of very dark conditions you can increase shutter time (do not go beyond 1/1000s) and ISO (do not go beyond 3200). In case of very bright conditions you can decrease the ISO value. As a photogrammetry expert you can of course also try out different settings. If you want to adjust camera settings before every flight, you can use the cameras "Program Mode" and set shuttertime, aperture and ISO to the sweet spot (shuttertime ~ 1/2000s, aperture ~ 5, ISO depending on conditions). Make sure you do not face the camera into the sun when adjusting the settings in Program Mode. Focus should be set to "manual focus" and infinity. Auto focus leads to inaccurate geotagging and potentially holes in the map due to missed triggers. We recommend not touching the focus unless you have problems with image sharpness. After exchanging lenses (from 15mm Voigtländer to the 16/20mm lens) we highly recommend to confirm a good focus setpoint of the lens prior to the first flight. To check the focus setpoint of the camera place the WingtraOne with the camera facing to the horizon and power the WingtraOne. Then remove the top cover and press the on/off button of QX1 and connect to camera using the PlayMemories App on your tablet. You should see a live view of the camera image. Take a picture and pinch to zoom into the fetched image on the tablet. If the image is sharp just disconnect the camera from the Playmemories App by pressing the back button on the tablet twice. If the image is not sharp you should adjust the focus set point, as explained in the troubleshooting section. QX1 with 15mm Voigtländer Lens Light Camera Shutter Aperture,...
  • Page 18 Camera WingtraOne takes a series of test pictures after you press the Ready-To-Fly button during the preflight procedure to check if the camera is setup correctly, i.e. to make sure that the SD card is inserted correctly and triggering from the autopilot is possible. Listen to the camera after you press the Ready-To-Fly button. If you hear the shutter opening and closing (clicking sound) you can be sure that everything works fine. If you run into trouble, check the section below before reaching out to Wingtra Support. Troubleshooting WingtraOne QX1 Q: Camera: My camera does not connect over WiFi Make sure that your camera is powered (green LED on the camera housing) Restart the PlayMemories App and see if you can connect now. Take camera out of the foam (you have to diconnect the violet cable) and look at the tiny screen. Check if you can read on the screen — if not, open the camera cover and click the small WiFi WiFi button to change to single-channel WiFi mode. Close the cover and try to connect again. Reconnect the violet cable after you re-inserted the camera to the mount. The Sony QX1 has 3 WiFi modes: No WiFi Single-channel WiFi (preferred) Multi-channel WiFi (also functional) Q: Camera: My images are blurry Check if there is dust/water on the lens The Sony QX1 is set to manual focus mode to ensure accurate triggering (minimizing triggering time delays). If you see that the images are out of focus, you have two options to adjust manually: Option 1: Power WingtraOne, manually switch on the camera (press On/Off button on camera housing), connect the camera to the Playmemories App via Wifi and take the camera out of the foam (you have to disconnect the violet cable) and adjust the focus manually to infinity. To do that point the camera towards a remote object and turn the focus ring clockwise (looking into the camera) for a whole turn followed by slowly turing the ring back (counterclock wise) by 5 to 10°. By carefully observing the image displayed on the tablet you can find the point of maximum sharpness for remote objects. Expose a few images and check the image sharpness on the tablet. Once you are satisfied disconnect the camera from the Playmemories App by pressing the back button on the tablet twice and turn off the camera by pressing the on/off button. Reinsert the camera in the the mount and reconnect the violet cable. Option 2: Power WingtraOne, manually switch on the camera (press On/Off button on camera housing), open the PlayMemories app on your tablet and connect to the camera. Change focus mode to Auto, point the camera center to clouds or an object more than 50m away, wait until the focus adjusts, and switch back to manual focus. Than disconnect the camera from the PlayMemories App by pressing the back button on the tablet twice and turn off the camera by pressing the on/off button.
  • Page 19 Camera Q: Camera: My images are too dark Increase shutter time and/or ISO. See also the section on camera settings. Q: Camera: My images are too bright Decrease ISO. See also the section on camera settings. Q: Camera: The LED on the camera is blinking red If the SD card is not inserted correctly the LED is blinking red when the camera tries to capture an image. Q: Camera: What is the meaning of the messages “Test picture process started" and "Test pictures are taken"? The autopilot performs a routine after pressing the Ready-To-Fly button that triggers 4 test pictures. If you hear the shutter on the camera, your camera is setup correctly (SD card is inserted correctly and triggering of WingtraOne works). The process takes approximately one minute, starts with the message "Test picture process started" and ends with "Test pictures are taken". Q: Camera: I did not capture images during flight Check if you have removed the lens cover Check if you have inserted the SD card correctly Check if your SD card has free space Repower WingtraOne, press Ready-To-Fly, and listen to the camera shutter sound from the test pictures (automated preflight routine).

  • Page 21 Light Shutter Aperture, Image Mode Program Conditions Speed [s] f-Number Settings Quality Dial Mode Manual Auto extra default 1/2000 Exposure fine The default settings give good results in large range of light conditions. The maximum ISO the camera will adjust is ISO 6400. In case of dark conditions you can decrease the shutter speed down to 1/1500s or open the aperture further (take the camera out and turn the aperture ring). To save different exposure settings permanently they have to be stored as a memory recall function. Adjust the desired settings on the camera like file size, compression, metering mode, WB, shutter priority, shutter speed, ISO. Go to the settings menu and save the settings to memory recall "1" or "2". Make sure not to overwrite the default settings by Wingtra on "3". Then turn off and on the camera via the Power switch on the camera. To use the desired exposure settings set the Mode Dial to the respective setting. WingtraOne takes a series of test pictures after you press the Ready-To-Fly button during the preflight procedure to check if the camera is setup correctly, i.e. to make sure that the SD card is inserted correctly and triggering from the autopilot is possible. We recommend opening the WingtraOne cover and inspect the routine on the camera screen. After pressing the "Ready-to-Fly" button the camera is switched off and on again, than the test pictures are taken (you can see the counter of remaining space on SD card on top left of the screen going down), and finally the camera is switched off again. If you run into trouble, check the section below before reaching out to Wingtra Support. The manual aperture ring can be set to any value only mechanically via the Aperture Selection Ring. There is no storage setting for the correct aperture in manual mode. For more information about the camera see the official Sony Documentation. Troubleshooting WingtraOne RX1R2 Q: The images are over or underexposed.
  • Page 22 Camera Check whether you use the memory recall function 3 with the correct default settings Check whether the EV correction dial is set to +-0 EV Q: The images look blurry The focus is not set to infinity. To set the focus distance correctly power up the WingtraOne. Make sure that the camera is in Manual Focus mode (Focus mode dial (8.) on MF) and turn the Focus Ring on the lens such that the focus indicator on the display just reaches infinity at the right edge. Continuously turning further will make the image blurry again. Check whether camera is in none macro mode. Q: The camera does not keep the adjusted settings after repowering WingtraOne To store camera capture settings permanently the camera has to be turned off and on again via the On/Off switch. Unpowering the WingtraOne directly cuts the power of the camera and does not keep time to save settings. Q: The geotagging process lasts very long The file size of individual images taken with the RX1R2 are up to 35MB. For large projects with high overlaps that results in project sizes up to 50GB of image data. Handling of this amount of data on the tablet can take up to 2h of processing time Q: No images are taken No SD card was inserted during flight The On/Off switch is on Off...

  • Page 25: Battery Charging

    Battery Charging Charging Before going to the field you have to charge the flight batteries, the remote control (RC) and the tablet. The following sections describe how to charge the flight batteries. Li-Ion Batteries The WingtraOne is powered by a pair of 4S3P Lithium-Ion batteries. For a charging manual see below. Lithium-Ion battery packs may get hot, explode or ignite, and cause serious injury if exposed to abusive conditions. Be sure to follow the safety warnings listed below: Do not connect the positive terminal and negative terminal of the battery to each other with any metal object (such as wire). Do not pierce the battery with nails, strike the battery with a hammer, step on the battery, or otherwise subject it to strong impacts or shocks. Do not expose battery to water or salt water, or allow the battery to get wet. Do not attempt to charge an over-discharged or damaged battery, but dispose this battery safely. Always use the correct charging mode (Li-Ion balancing). Do not leave battery packs unattended during charging and make sure to place the batteries away from easily flammable environments such as wood or carpet. It is recommended to charge batteries in a fire proof container. We expect all users of Li-Ion batteries to be professionals and to have the capability to handle emergency cases. Batteries of the first batches of WingtraOne are explicitly experimental batteries that require an extra level of care, i.e. they do not hold for the UL Test Standard for Li-Ion and packs. Charging Li-Ion 4s3p batteries You can use the included charging system either on a power plug or on the field using car battery for charging. Set up your charging system as shown below and follow the following instructions: Select the mode by clicking on “Batt Type”, navigate to Li-Ion mode with the “Dec” and “Inc” buttons, and confirm with the “start/enter” button.
  • Page 26 Battery Charging Set the number of cells to 4S, which corresponds to 14.4V, and the charging current to 7.5A, which corresponds to 1C. Confirm with “enter”. Confirm your settings by pressing the “enter” button for 2 seconds. Check the settings (Li-Ion balancing mode, 4S (14.4V), 7.5A), and confirm by pressing “enter”. Charging of empty batteries takes approximately 1 hour. Once the charging is finished you get an audio confirmation and you can see the message "finish" on the display (16.4 Volt corresponds to fully charged batteries). Use and charge the 4S batteries always in pairs as they are labeled (pairs have the same color), i.e. do NOT fly with two batteries with different color labels.

    Interact with WingtraOne Carry WingtraOne You can carry the WingtraOne easily if you hold it at the wing area between the propellers and the battery compartment or at the motor mounts. Attach and detach Middle Stand The middle stand is not symmetric. Make sure that the shape of the midsection of the middle stand matches the shape of the airframe. The middle stand can not be inserted properly in the wrong direction. To attach the middle stand, we recommend holding WingtraOne with one hand and turning it vertically. Then simply attach the middle stand and secure it with the elastic band. To detach the the middle stand, lift WingtraOne by holding the two motor mounts. Turn WingtraOne vertically and place one hand between the upper motor mount and the battery compartment. With the other hand, remove the security elastic band and detach the middle stand. Power WingtraOne Open battery compartment and insert batteries Power WingtraOne by connecting the yellow ports, the cables need a firm push. The balancer ports do not need to be connected. Make WingtraOne Ready-To-Fly WingtraOne is equipped with a single LED-button — the Ready-To-Fly button — which needs to be pressed in the preflight procedure. Before pressing the button, no signals are sent to the motors and flaps. After powering, WingtraOne enters a neutral state (not ready-to-fly), which is indicated by a slowly blinking Ready-To-Fly button (- - - - - -). By pressing the button, you put WingtraOne into Ready-To-Fly state, indicated by a double blinking LED (- - -- -- --). When WingtraOne enters the Ready-To-Fly state, it runs a routine that checks the functionality of both flaps. It then starts a process to check the functionality of the camera by capturing some test pictures. For further details, see the preflight checklist chapter. Once WingtraOne is in Ready-To-Fly state and all preflight checks have been fulfilled successfully, it's only then that you can start the flight from tablet. During flight, the button is not blinking but solid on (------- ----). After landing, the LED changes back to blinking (-- -- -- --), which means that WingtraOne can be approached without risk.

    WingtraPilot Overview Meet WingtraPilot WingtraPilot is your interface with the WingtraOne and enables you to collect high quality aerial imagery. WingtraPilot's main functionalities include flight planning, flight execution, geotagging, loading of offline maps and upgrading the WingtraOne firmware. Starting WingtraPilot on your tablet, you will see the welcome menu. You can always go back to the welcome menu by clicking on the orange Wingtra icon on top left of the screen. What you can do with WingtraPilot 1. Create a new Flight Plan You can either create a Flight Plan from scratch or create a new one based on an existing Flight Plan. You have to create a new Flight Plan for every flight. Follow the instructions in the interface to enter the flight planning itself. Below you can find a sample flight planning. See here for details on flight planning. 2. Open an existing Flight Plan...
  • Page 34 WingtraPilot Overview You cannot modify a Flight Plan that has been flown already. If you want to refly an already flown Flight Plan, click onto the first option "Create a new Flight Plan" and choose "Based on existing Flight Plan". Use "Open an existing Flight Plan" in the following two cases: 1. You planned a flight in office and want to fly or modify it now. 2. You want to inspect settings of an already flown Flight Plan. 3. Geotag an existing Flight Plan Collected images are saved on the SD card in the camera without assigned GPS information (geotags). Geotagging appends this information to the image metadata. Geotagging should always be done right after flight, where you will be guided through the process of geotagging.

  • Page 36: Flight Planning

    Flight Planning Create a New Flight Plan To start planning a flight, you have to "Create a new Flight Plan" from the welcome menu of WingtraPilot. You can open the welcome menu by clicking on the orange Wingtra icon on the top left. Follow the interface to setup the high-level settings of the Flight Plan — Do you want to start from scratch or based on an existing Flight Plan? Do you use an RGB or multispectral sensor? Click on finish and you will enter the flight planning display of WingtraPilot: The flight planning procedure itself contains these steps: Set Home Add Area(s) (Optional) Adjust Geofence Step 1 Set Home for takeoff and landing Add Home by clicking on the first button on the left (A). If you are on the field and the WingtraOne is powered and connected to the tablet, Home is set to WingtraOne's current position automatically. If you plan the flight beforehand in office, you can move it to the place where you intend to takeoff — it will be adjusted to WingtraOne's location once you are on the field. Adjust "transition altitude" and "transition direction" on the right side (C) such that WingtraOne will not collide with any obstacle.
  • Page 37 Flight Planning WingtraOne will take off, rise to your "transition altitude" above Home, transition into forward flight, fly to the drawn loiter circle, loiter up to the area altitude and start data collection. After finishing data collection, it will fly back to the loiter circle at the altitude of the last area, loiter down to "transition altitude", fly back to the Home point, transition above Home, and land. Note that if you are not connected to the WingtraOne or if there is no GPS lock, Home is added to the center of the screen — where the location in WingtraPilot is set to the location of the last flight. To change the location, select the “Street Map” tiles, navigate to your position, and switch back to "Satellite Map". Step 2 Add Area(s) You can add one or several area(s) for data collection to your Flight Plan by clicking on the area item (A). Choose your desired ground sampling distance (or, alternatively, your desired altitude) on the right side and adjust the flight direction if needed. Move the corners (minus signs) and add additional corners until you draw the area(s) that you want to map. WingtraPilot will warn you if you set up a mission that is too large. You can also adjust the side overlap of the images. Decrease the overlap to maximize the area/minimize the flight time. Increase the overlap to optimize the final map quality. Reliable orthomosaics can be created with imagery down to 60% side overlap for flat areas. For more sophisticated landscapes you have to increase the overlap, see the troubleshooting section below for more details. Step 3 (Optional) Adjust Geofence...
  • Page 38 Flight Planning You can adjust the geofence by clicking on the respective menu on the right side (E). Click on the triangle to unfold the menu. By default, horizontal geofence is set to 1200m and vertical geofence is set to 400m. This maximum alloweable distance can be increase to satisfy the needs for special mission planning purpose. Increasing the geofence size allows to operate the WingtraOne beyond visual line of sight (VLOS). Make sure before changing the geofence limits that WingtraOne is operated within the local legal boundaries for drone operation. Example Flight Planning Flight Planning on the Field As flight planning with WingtraPilot is very easy, we recommend to plan your flight directly on the field. If planning is performed on the field, it is recommended to set up equipment (power WingtraOne → connect telemetry → start WingtraPilot) before planning the flight. Make sure you have internet access on the field or download offline maps before going to the field. Troubleshooting Q: Flight Planning: The area that I want to map is not flat. What can I do? The current version of WingtraPilot does not support automated terrain tracking. This feature will be integrated in coming releases. If you want to account for different elevations, you can plan multiple areas with different flight altitudes and execute them in one flight. Be aware that areas that are above the take-off point will have a better resolution (e.g. displayed: 3cm/px, actual: 2.5cm/px) and a smaller overlap (displayed: 70%, actual: 60%) than what you set during planning. areas that are below the take-off point will have a worse resolution (e.g. displayed: 3cm/px, actual: 3.5cm/px) and a larger overlap (displayed: 70%, actual: 80%) than what you set during planning. If possible, you can plan several areas on top of each other with different flight directions (e.g. cross shaped). This gives you better imagery for 3D structures. Q: Flight Planning: is it better to takeoff on a higher or lower place in the area? If you have the choice, we recommend to start on a high point as you have a better overview and it is easier to setup a flight plan that prevents collisions with obstacles. If you start on a high point, be aware that the ground sampling resolution is worse than planned (e.g. displayed: 3cm/px, actual: 3.5cm/px) and the overlap is larger than planned (displayed: 70%, actual: 80%). If you start on a lower place, be aware that the ground sampling resolution is better than planned (e.g. displayed: 3cm/px, actual: 2.5cm/px) and the overlap is smaller than planned (displayed: 70%, actual: 60%).
  • Page 39 Flight Planning Q: My Map Tiles are not loading. There is a bug in loading the map tiles that sometimes occurs if you connect to WiFi after starting WingtraPilot. If your maps do not load, you can either restart WingtraPilot or change to another map provider (on the Settings --> General menu).

  • Page 40: Preflight Checklist

    Preflight Checklist Preflight Checklist You are guided through the process of setting up your WingtraOne by the preflight checklist within WingtraPilot. As the operator, you have to go through the preflight checklist within WingtraPilot before you can start the flight. If any of the preflight checks fails (e.g. sensor failure), the respective preflight check turns red and starting the flight is not possible. Below you can find an explanation for every checkpoint in the preflight checklist and troubleshooting advice if a check fails. 1. Hardware: Distance sensor clean? Propellers not damaged and well attached? Camera lid removed? Check if the distance sensor is dusty or is covered by something (snow, tape, ...). The distance sensor is located at the tail of WingtraOne, next to the middle stand. If it is not clean or if you are not sure if it is clean, take the time to clean it with a clean blanket. Visually check if propellers are not damaged and well attached. Try by hand to unscrew the propeller (hold motor with one hand and the propeller with the other hand and try to open it). If the propeller unscrews by hand, tighten the nut with the hex-wrench tool as much as you can. See the maintenance chapter for how to replace a propeller if damaged. Remove the camera protection lid. Put it in the Pilot Box, it is easy to lose. Confirm by clicking the checkpoint in the checklist. Do not fly if any part of WingtraOne is damaged. 2. Place WingtraOne on takeoff point.
  • Page 41 Preflight Checklist 3. Connect telemetry link to tablet and power WingtraOne. After WingtraOne is powered and telemetry is connected to the tablet, WingtraPilot automatically tries to connect. This point in the checklist is an automated test. Connect the telemetry to the tablet at the entry right to the home button. Connect manually if you do not get connected automatically. 4. Check battery voltage This is an automated test. WingtraPilot checks whether the battery voltage is above 30V. If voltage is below 30V take-off is prevented and you have to switch batteries. 5. Check even takeoff position This is an automated test. WingtraPilot checks whether WingtraOne is standing on even ground. Move WingtraOne if the check is red. If WingtraOne is level and the check stays red, repower WingtraOne. 6. Turn on the remote control Switch on the RC on the On/Off button in the middle of the RC. After switching it on, it automatically connects to WingtraOne and you can see the RC battery charge and the signal strenght of the connection on the top left of the RC screen. This check is not yet automated, confirm by clicking the checkpoint in the checklist. 7. Check GPS signals This is an automated test. Depending on weather, it can happen that your WingtraOne does not receive GPS lock for several minutes. If GPS lock cannot be established after more than 5 minutes, try to repower WingtraOne. If you still fail to establish connection, open the battery cover and see if the cable to the GPS module is well connected. If you still fail to get reception, chat with the Wingtra Support. 8. Calibrate airspeed Take the pitot covering out of the pilot box and cover the pitot tube with it. Start airspeed calibration by clicking on the checkpoint in the checklist. You will receive the instruction "Ensure sensor is not measuring wind". Wait until you hear the confirmation of WingtraPilot: "Blow into pitot tube without touching". Then, remove the pitot covering and blow straight into the tube. If Airspeed calibration fails, you can restart it by clicking onto the respective checkpoint again. You have to blow directly into the tube. In windy weather conditions the Airspeed calibration can fail frequently. To avoid frequent retrials shield the pitot tube with your hand from wind by forming a cylinder around the tube when blowing into it from the top. 9. Press Ready-To-Fly button on your WingtraOne You make WingtraOne ready to fly by pressing the Ready-to-Fly button for 2 seconds. There will be a confirmation sound and the Ready-to-Fly button will start to blink with double blinks ( -- -- -- -- ). By making WingtraOne ready to fly, you allow for signals to the motors and flaps, and start a routine that checks the camera by taking some test pictures. This point in the checklist is an automated test.
  • Page 42 Preflight Checklist If WingtraOne does not react when pressing the Ready-to-Fly button, try again and make sure that you hold the button for 2 seconds. If it still does not work, repower WingtraOne. For more information about the Ready-to-Fly state, see the chapter on how to Interact with WingtraOne. 10. Check startup flap movement After making WingtraOne Ready-To-Fly, the flaps perform a startup routine (see video above). Check if it is run correctly and confirm by pressing this checkpoint. DO NOT FLY if the routine does not run properly (e.g. one flap is not moving at all) and contact the Wingtra Support. 11. Camera readiness After pressing the Ready-To-Fly button, WingtraOne triggers 4 test pictures within one minute. If you use QX1, listen if you can hear the camera's shutter. If you hear the shutter you can be sure that you get images during flight. If you use RX1R2, open the cover and watch on screen if pictures are taken. You will see, the camera is first switched off and on again, than the test pictures are taken (you can also see the counter of remaining space on SD card going down on top left of screen), and finally the camera is switched off. If test images are not taken, check if the SD card is inserted correctly. Wait for the audio-feedback "Test pictures are taken" before taking off. Remark: WingtraPilot does not get feedback whether taking test pictures succeeded, the message "Test pictures are taken" appears always after finishing the sequence. 12. Review Flight Plan and upload to WingtraOne After you have planned your flight, make sure you review the flight plan: Make sure WingtraOne will not collide with any obstacles. Also check that your flight does not violate laws or WingtraOne market-entry restrictions. Click on this checkpoint in the preflight checklist to upload the flight plan to WingtraOne. WingtraPilot saves the Flight Plan automatically when you upload it by clicking on this checkpoint. 13. Check whether there are no people within 5m around the plane and if the weather conditions and airspace are suitable to fly. Check if the conditions are suitable to fly (check flight conditions) and make sure no people are close to WingtraOne. Confirm by pressing this checkpoint in the checklist. Once you have successfully completed all previous steps, you can fly WingtraOne. To start the flight click on "Start Flight" and move the slider left to right. The Ready-to-Fly button will go solid green (-------) once WingtraOne starts flying. Troubleshooting Known Issue: Initialization Failure of WingtraOne...
  • Page 43 Preflight Checklist In rare cases, WingtraOne fails to initialize the sensors correctly during boot up. In this situation you either fail on the even ground preflight check, see WingtraOne heavily drifting in the map (more than 5-10 meters), or get the following warning: PREFLIGHT FAIL: Estimator error. Reboot WingtraOne. If you run into initialization failure, repower WingtraOne.

  • Page 44: Flight Modes

    Flight Modes Terminology: Flight Mode and Flight Regime The flight mode defines if WingtraOne is flying autonomously (Auto), if you are flying in Assisted Mode, or if Return-to-Home (RTH), is engaged. The flight regime of WingtraOne is either Hover or Cruise. Hover is the vertical mode that is used during takeoff and landing, Cruise is the horizontal, forward flight mode, where WingtraOne flies like a fixed-wing aircraft. Flight Modes Auto Mode This is the normal mode in which WingtraOne flies the planned flight autonomously from takeoff to landing. Return-to-Home (RTH) Engage RTH if you realize something is wrong and you want WingtraOne to come back autonomously. If RTH is engaged, WingtraOne flies back to the planned loiter circle on its current flight altitude. It then loiters down to the planned transition altitude, flies back to the Home point, transitions above the Home point and lands. For more details, see the failsafes chapter. Assisted Mode You can fly WingtraOne manually in Assisted Mode. Switch to Assisted Mode before landing (after back- transition) to adjust the landing point if necessary. Engage the Assisted Mode by pressing the respective button on the remote control (RC). The flight regime will stay as it was before you switched to Assisted Mode, i.e., if you engage Assisted Mode during cruise flight, you will take over in cruise, and if you engage Assisted Mode during hover flight, you will take over in hover flight. If you fly in Assisted Mode, you can transition between the two flight regimes with the transition button on your remote control. See the section about manual flying for a detailed description of how to fly with the remote control.

  • Page 45: Interactions & Assisted Mode

    Interactions & Assisted Mode In-Flight Interactions The following table summarizes your options to interact during flight. Possible Interactions Action Consequence Emergency Stop: Kill all motors and spiral down. The plane flies back autonomously at the current altitude, performs the RTH (Return-to-Home): planned landing procedure and lands. Gives the pilot authority via the remote control (RC). Engage only if Assisted Mode: you know how to fly the WingtraOne! Transition (Only works in Lets WingtraOne transition between hover and cruise. Assisted Mode): You can take all described actions from the RC by pressing the respective buttons. To trigger Emergency Stop you have to click the red button 3 times within 2 seconds. You can engage Return-to-Home (RTH) and trigger Emergency Stop also from tablet by clicking on the respective buttons and moving the slider left to right. THERE IS NO WAY TO REGAIN CONTROL ON EMERGENCY STOP! Manual Flying in Assisted Mode Use the remote control for manual flying in Assisted Mode. Read the following section carefully before you switch to Assisted Mode. Use the "Assisted" button (5.) on your RC to switch from Auto Mode to Assisted Mode. Be aware that there are no extended safety features (collision avoidance or similar) available for WingtraOne. Flight Instructions The main reason to take over (switching to Assisted mode) should be to hold or adjust the position before landing. Taking over in cruise is a safety feature that can be used e.g. in case of bird attacks. When flying in Assisted Mode you won't be able to collect images. WingtraOne can severely harm people if handled inappropriately. Only fly WingtraOne manually if you know what you are doing. Depending on GPS quality, WingtraOne can drift for several meters. Be prepared to react.
  • Page 46 Interactions & Assisted Mode Hover Flying WingtraOne in hover works similarly to flying a multicopter. WingtraOne will keep its position if you do not touch the sticks. Likewise, it will move according to your control stick input. Cruise You can fly WingtraOne in cruise mainly with two control inputs: rising/sinking (pitching) and turning. WingtraOne will fly at constant altitude and speed (16 m/s) if you do not touch the sticks and rise/sink/turn according to your control stick input. Transition Use the transition button (6.) to transition from hover to cruise or vice versa. Forward-transition (hover->cruise): Make sure you are on a safe altitude before you transition into forward flight (cruise). There is no option to rise or interact in any way during transition! Back-transition (cruise->hover): The back-transition needs a lot of space. Engage it 40 meters before you reach the point at which you want to hover. Always engage back-transition at a safe distance and altitude away from obstacles and yourself. There is no option to interact in any way during transition! Landing If you are flying in cruise, transition back to hover by using the transition button (6.) at a safe distance and altitude. Change heading after back transition such that the Wingtra logo is facing you. Direct WingtraOne to its intended landing position. WingtraOne will use its distance sensor to detect landing and switch-off the engines at 10cm distance above ground. Remote Control...

  • Page 52: Failsafes

    Failsafes Failsafe Scenarios There are several scenarios where WingtraOne will take action by itself and engage a certain failsafe routine. Return-to-Home RTH is triggered when the geofence is violated, when both telemetry and RC connection are lost, or when battery charge triggers this failsafe. It can also be triggered manually. You can take over manually during Return-to-Home by switching to Assisted Mode.

  • Page 54: Geotagging

    Geotagging Geotagging The collected images are saved on the SD card in the camera without assigned GPS information (geotags). The current workflow includes some user input to assign the geotags to the images. Leave WingtraOne powered after landing until the geotags are downloaded to the tablet (Step 1: Download Geotags). Steps to Geotag your Images Step 1: Download Geotags After landing, WingtraPilot starts downloading the geotags automatically and displays the progress: Be patient and wait until the download succeeds. If the download fails, click on "Retry" and walk towards WingtraOne to get better connection. We highly recommend to geotag always right after flight. Click on "Geotag Images" to do so. Step 2: Geotag your Images on the Tablet Power off WingtraOne, get the SD card from the camera and insert the SD card to the tablet. Check if the right Flight Plan is selected (change if not), select the directory on the SD card containing all images as image directory, and click on "Start Tagging" (B).
  • Page 55 Geotagging A: Section for the Geotag Download (normally not needed). B: Section for the Geotagging itself. Wait for the feedback "Success! ...". Be patient! Geotagging the images can take several minutes (for huge sets with thousands of images it can take up to 20 minutes). WingtraPilot creates a folder in the image directory (on the SD card) containing the original images, the tagged images, the Flight Plan file and a json text file with the geotags including attitude tags (see below). You can plan the next flight in parallel and continue collecting more data, while the geotagging takes place in the background. If you want to start the next flight already in parallel to the geotagging, you need a second SD card. Geotagging can fail if the camera's internal counter exceeds its maximum of 10'000 images. If that happens, the camera creates a new folder for the new images. Click on the "+" button and select the second image directory and start geotagging again. Do not inspect the images during geotagging. Geotagging can fail if you open the images in another app during tagging. If that happens, restart geotagging from WingtraPilot. Step 3: Inspect and Save the Images To inspect the images on the tablet, open the "MyFiles" App, navigate to SDcard/DCIM/ and into your project folder, open an image by clicking on it and select "Gallery" as image viewer. To continue working, remove the SD card from the tablet. You can either save the data from the SD card to your computer after every flight and clear the SD card (recommended) or continue collecting data and upload the data at the end of the day. The SD card provides enough space for several flights (up to 3000-4000 JPEG images). Step 4: Continue Working To continue working with WingtraOne, re-insert the SD card to the camera. Results of Geotagging on the SD Card...
  • Page 56 Geotagging As a result you get a folder named after your Flight Plan in the image directory on your SD card. It contains the following objects: /ORIGINAL subfolder: Unmodified images /TAGGED subfolder: All images of the flight with geotags in metadata /date_time.flightplan file: The Flight Plan that was flown. This file can be loaded in WingtraPilot if you want to fly the same Flight Plan again. /date_time.json file: A text file containing time, GPS coordinates and attitudes for all images. Geotag an existing Flight You can always geotag an old flight at a later time again. Select "Geotag an existing Flight" on WingtraPilot's welcome menu and select the respective Flight Plan. Put the original images of the flight into a separate folder on an SD card and insert the SD card into the tablet. Select the respective image directory within WingtraPilot and click on "Start Tagging". Troubleshooting Q: At the end of geotagging, I get a warning "Failure of dataset likely: Long time span between images" Most often when this message appears geotagging worked as desired. During the process of geotagging time intervals between images are checked as a quality assessment. If the time interval between the test images from the preflight procedure and the first in-flight image is too long this message is generated although everything worked as expected. Q: At the end of geotagging, I get a warning "Failure of dataset likely: More images than triggers"...
  • Page 57 Geotagging Most often when this message appears geotagging worked as desired. Normally, there should not be more images than the number of triggered images plus the test images from the preflight procedure. If there were additional images on the SD card prior to flight (or, if WingtraOne needed to be repowered before takeoff and the test pictures were taken twice) this message appears. Q: At the end of geotagging, I get a warning "Failure of dataset likely: Bad matching score" This indicates that the geotags are probably less accurate than normally. If this message appears often on your WingtraOne, contact the Wingtra Support. It is possible that something with the triggering is not working as expected. Q: At the end of geotagging, I get the feedback "removed 0 preflight images" WingtraOne does not classify non-flight images as preflight images in case it was repowered before takeoff but after some pictures were already taken. Although not classified correctly, it assignes the geotags correctly to the in-flight images. Hence, normally this info can be ignored. Q: Can I take and geotag RAW images? At the moment, geotagging of RAW images is not supported. Q: I forgot to geotag the images after flight and performed a second flight. Geotagging fails if images of several flights are on the SD Card. In case you forgot to geotag the images from a first flight after flight, and you collected additional images in a second flight, you can use the following workaround: 1. Save images from different flights into different folders on the SD card (order the images after name and split them on the test pictures of the second flight). 2. Run the geotagging of the individual flights on the respective folders. Q: I powered off the WingtraOne before the geotag download succeded. What can I do? If you powered off the WingtraOne before the geotag download succeded (Step 1), you can repower the WingtraOne. You will be asked if you want to download the geotags now. If you are not asked by WingtraPilot, go to the geotagging menu and click onto "retry downloading geotags for your latest flight". Geotags of older flights, which were not downloaded, are lost permanently.
