  • Page 9 Quick Start Guide A: Flight Planning B: Adjust Flight Settings (Home / Takeoff / Area(s) / Landing) C: Flight Summary Plan a flight in 3 easy steps. For more details, see the flight planning chapter. STEP 1 Set Takeoff / Landing point: Add the takeoff/landing point by clicking on the item on the left side (A) and to the desired location in the map. Adjust "transition altitude" and "transition direction" on the right side (B). The WingtraOne will take off, rise to your "transition altitude" above the takeoff/landing point, 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 the "transition altitude", fly back to the takeoff/landing point, transition above the takeoff/landing point and land. STEP 2 Add Area(s): You can add one or several 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 (B) and adjust the flight direction and side overlap if needed. Move the corners (minus signs) and add additional corners until you draw the area that you want to map. STEP 3 Review the Flight Plan: Make a thorough terrain review - make sure the WingtraOne will not collide with any obstacle. Furthermore, check that your flight does not violate laws or the WingtraOne market-entry restrictions. 5 (Optional) Adjust Camera Settings You can adjust the camera settings from the tablet. Turn on the camera within the WingtraOne by clicking on the On/Off button, open Sony's PlayMemories app on the tablet, and adjust the settings. The camera will keep the settings you adjust and won't reset to the defaults on the next flight, for more details see the camera chapter. Well tested default settings are:...

If any of the preflight checks fails (e.g. sensor failure), the respective preflight check turns red and starting the flight is not possible. For a detailed description about all preflight checks and troubleshooting advice, see the preflight checklist section. The WingtraOne takes a series of test pictures during preflight procedure to ensure the camera is working. 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 the WingtraOne. Take off by clicking onto "Start Flight Plan" and moving the slider slowly left to right. Repower the WingtraOne always between flights. Do not take off again after landing without depowering and repowering the drone. 8 Flight Observation...
  • Page 11 Quick Start Guide Always observe the WingtraOne during flight. A: Information about the 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 the WingtraOne and let it land autonomously. The WingtraOne will autonomously engage Return-to-Home in case of low battery, geofence violation, or if both telemetry and RC connection are lost. For more 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 the 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 the geotags to the images, you need to perform the following 3 steps.
  • Page 12 Quick Start Guide STEP 1: Download the Geotags After landing, WingtraPilot will start downloading the geotags automatically. If the download fails, click on "retry" and walk towards the WingtraOne to get better connection. STEP 2: Geotag Images on the Tablet Depower the WingtraOne, get the SD card from the camera and insert the SD card to your tablet. Open the geotagging menu in WingtraPilot, enter a flight name, select the correct (newest) flight from the list, select the image directory on the SD card that contains your images, and click "Start Tagging". Be patient! Geotagging the 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 the 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.

If you see that the images are out of focus, you have two options to manually adjust: Option 1: Power the WingtraOne, manually switch on the camera (press On/Off button on camera housing), take the camera out of the foam (you have to disconnect the violet cable) and adjust the focus manually to infinity by turning the focus ring clockwise (looking into the camera) for a whole turn. Reconnect the violet cable after you re-inserted the camera to the mount. Option 2: Power the 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. Q: Camera: My images are too dark Increase shutter time and/or 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 is trying 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 the drone 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 the Wingtra plane, press Ready-To-Fly, and listen to the camera shutter sound from the test pictures (automated preflight routine).

  • Page 23: 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 Lithium-Ion batteries. The drone can be powered by single 8S3P or pairs of 4S3P battery packs. The charging setup is different for the two types (see below for 8S3P charging and 4S3P charging) 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 user of Li-Ion batteries to be professionals and have 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.

  • Page 27: Interact With Wingtraone

    Interact with WingtraOne Carry the 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 the WingtraOne with one hand and turn it vertically. Then simply attach the middle stand and secure it with the elastic band. To detach the the middle stand, lift the WingtraOne by holding the two motor mounts. Turn the 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 the WingtraOne with single-battery 8S design Open battery compartment and insert battery Power the WingtraOne by matching the red cable with the red one and the black with the black one. The cables need a firm push. The balancer port does not need to be connected. Power the WingtraOne with split-battery 4S design Open battery compartment and insert batteries Power the WingtraOne by connecting the yellow ports, the cables need a firm push. The balancer ports do not need to be connected.
  • Page 28 Interact with WingtraOne Make the WingtraOne Ready-To-Fly The 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, the 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 the WingtraOne into Ready-To-Fly state, indicated by a double blinking LED (-- -- -- --). When the drone enters the Ready-To-Fly state it runs a routine that checks functionality of both flaps. Moreover it starts a process to check the functionality of the sensor by capturing some test pictures. For more detail, see the preflight checklist chapter. Only if the drone is in Ready-To-Fly state and if all preflight checks are fulfilled successfully, 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 the WingtraOne can be approached without risk.

  • Page 29: Maintenance And Update Process

    Maintenance and Update Process Maintenance and Update Process The WingtraOne does not need maintenance in normal operation. The following How To's describe how to replace parts that can get damaged during transport or after tipping while landing the WingtraOne on uneven ground. You can order replacement parts via the Wingtra Support. You will profit from all software improvements Wingtra achieves (for WingtraPilot and the Autopilot) by getting the newest Software Updates. For the moment, you will be guided by the Wingtra Support in the process of updating your software. Replacement of Propellers If one of your propellers is damaged, you can replace it by unscrewing the metal nut with the tool in the pilot box (hex-wrench), removing the damaged propeller, adding the new propeller, and screwing the metal nut again (screw it strongly with the hex-wrench). The two propellers have different shapes and are color coded. Make sure you attach the propeller with the correct color (needs to match the color on the motor mount) on the correct side. Replacement of Airspeed Sensor (Pitot Tube) Please contact the Wingtra Support in case the mount of the airspeed sensor is broken. If the airspeed sensor is blocked or the metal tube itself is broken, you can unscrew the mount of the airspeed sensor and replace the metal tube with a new one. Pay attention that you add the red plastic tube to the red port and the non-colored plastic tube to the non-colored port of the new metal tube. Replacement of Motor Mounts If the motor mounts are bent or broken you need to replace them. Do not bend them back! Replacing the motor mounts is non-trivial and takes approximately 30 minutes. Please contact the Wingtra Support and we will guide you through the replacement process. Replacement of Stands You can get a new middle stand if your stand is broken or damaged. There is no real maintenance work needed, simply take out the old and attach the new one.
  • Page 30 Maintenance and Update Process If a side stand is damaged or broken, you can replace it by unscrewing it with the tool in the pilot box (hex-wrench) and mounting a new one. Do not apply too much force when attaching the new side stands with the screws.

  • Page 34: Flight Planning

    Flight Planning Flight Planning The high level flight planning procedure contains these steps: Set home Add takeoff and landing waypoint Add area(s) Review flight plan You can either plan your flight in office or directly on the field. In either case, make sure you have internet connection on the field or load the satellite tiles beforehand. The following steps describe how to setup a standard flight plan in WingtraPilot. A standard flight plan consists of a takeoff/landing point and one or several areas for data collection, where each area is flown at constant altitude. The final flight path is calculated automatically. Step 1 Set Home Position If you are on the field and the WingtraOne is powered and connected, home is set automatically to WingtraOne's current position. If you are not connected to the WingtraOne or the drone has no GPS lock, the location in WingtraPilot is set to the location of the last flight. To change the location, select the “Street Map” tiles and navigate to your position. Click onto "Move Home to map center" once you are at the right location and switch back to "Satellite Map". Step 2 Set Takeoff And Landing Point Add the takeoff/landing point by clicking on the item on the left side and to the desired location in the map. Adjust "transition altitude" and "transition direction" on the right side. The WingtraOne will take off, rise to your "transition altitude" above the takeoff/landing point, transition into forward flight, fly to the loiter circle, loiter up to the planned area altitude...
  • Page 35 Flight Planning and start the data collection. After finishing the data collection it will fly back to the loiter circle on the area altitude, loiter down to the "transition altitude", fly back to the takeoff/landing point, transition above the takeoff/landing point and land. If there is substantial wind, face the forward transition into wind (and hence, perform the backtransition with the wind) to achieve the best wind robustness. You can plan your mission in office but be aware that you would probably have to change the exact takeoff/landing position on the field! Step 3 Add your Area You can add one or several area(s) for data collection to your flight plan by clicking on the area item on the left side. 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 orthomosaiks 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.
  • Page 36 Flight Planning Step 4 Review your flight plan Make a thorough terrain review - make sure the WingtraOne will not collide with any obstacle. Furthermore, check that your flight does not violate law or the WingtraOne market- entry restrictions. 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 → start WingtraPilot → connect telemetry) before planning the flight. This way, home is automatically set to WingtraOne's location. Make sure you have internet access on the field or load the satellite tiles before going to the field! Save Flight Plan to File Use the menu with the two arrows on the left side to save your flight plan to file, load a flight plan from file, or remove the planned flight.
  • Page 37 Flight Planning 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: Should I better takeoff on a high or low 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%). Q: My Map Tiles are not loading.
  • Page 38 Flight Planning 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 39: 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? 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 the 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. See the maintanance 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 the drone is damaged. 2. Place WingtraOne on takeoff point.
  • Page 40 Preflight Checklist 3. Connect telemetry link to tablet and power WingtraOne. After the WingtraOne is powered, it automatically tries to connect to WingtraPilot. This point in the checklist is an automated test. Connect manually if you do not get connected automatically. Connect the telemetry to the tablet at the entry right to the home button. 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 the WingtraOne is standing on even ground. Move the WingtraOne if the check is red. If the WingtraOne is level and the check stays red, repower the 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 the 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 drone does not receive GPS lock for several minutes. If GPS lock can't be established after more than 5 minutes, try to repower the 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 across front of pitot 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. 9. Review Flight Plan and upload to WingtraOne...
  • Page 41 Preflight Checklist After you have planned your flight, make sure you review the flight plan. Click on this checkpoint in the preflight checklist to upload the flight plan to the WingtraOne. It is good practice to save the mission additionally to file. If you plan on flying the WingtraOne manually in Assisted Mode, you can skip this checkpoint. 10. Press Ready-To-Fly button on your WingtraOne You make the 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 the 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. If the 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 the WingtraOne. For more information about the Ready-to-Fly state, see the chapter on how to Interact with WingtraOne. 11. Check startup flap movement After making the 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 chat with the Wingtra Support. 12. Camera readiness After pressing the Ready-To-Fly button, the WingtraOne triggers 4 test pictures within one minute. 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 do not hear the shutter sound, check if the SD card is inserted correctly. 13. Check whether there are no people within 5m around the plane and if the weather conditions are suitable to fly. Check if the conditions are suitable to fly (check flight conditions) and make sure no people are close to the drone. Confirm by pressing this checkpoint in the checklist. Once you have successfully completed all previous steps, you can fly the WingtraOne.
  • Page 42 Preflight Checklist To start the flight click on "Start Flight Plan" and move the slider left to right. The Ready-to- Fly button will go solid green (-------) once the WingtraOne starts flying. Troubleshooting Known Issue: Initialization Failure of WingtraOne In rare cases, the WingtraOne fails to initialize the sensors correctly during boot up. In this situation you either fail on the even ground preflight check, see the WingtraOne heavily drifting in the map (more than 5-10 meters), or get one of the following warnings: PREFLIGHT FAIL: EKF VERT VEL INNOVATIONS PREFLIGHT FAIL: EKF VERT POS INNOVATIONS If you run into initialization failure, repower the WingtraOne. Q: I get a failure message about missing Flight Plan when I want to start my flight, although the preflight check for Flight Plan Upload is green If the WingtraOne was repowered before flight but after uploading the Flight Plan, the preflight check stays green, although the Flight Plan needs to be uploaded again. Click on the green preflight check again to reupload the Flight Plan.

  • Page 43: Flight Modes

    Flight Modes Terminology: Flight Mode and Flight Regime The flight mode defines if the drone 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 the WingtraOne to come back autonomously. If RTH is engaged, the WingtraOne flies back to the planned loiter circle on it's current flight altitude. It then loiters down to the planned "transition altitude", flies back to the take-off/landing point, transitions above the takeoff/landing point and lands. Assisted Mode You can fly the WingtraOne manually in the 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, 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 how to fly with the remote control.

  • Page 44: 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. RTH (Return-to- The plane flies back autonomously at the current altitude, Home): performs the planned landing procedure and lands. Gives the pilot authority via the remote control (RC). Engage Assisted Mode: only if you know how to fly the WingtraOne! Transition (Only works Lets WingtraOne transition between hover and cruise. in 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 the 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. The WingtraOne can severely harm people if handled inappropriately. Only fly the drone manually if you know what you are doing.
  • Page 45 Interactions & Assisted Mode Do not take off manually in windy conditions. Depending on GPS quality, the drone can drift once it is in the air. Be prepared to react. Do not take off manually near any obstacles. If you command very aggressive maneuvers in cruise (e.g. maximum rising and maximum turning in cross winds), you can de-stabilize the WingtraOne to a point where you can not get back into control. Do not fly too aggressively! In case you de-stabilized the WingtraOne you can safe the drone by transitioning to hover. Hover Flying the WingtraOne in hover works similarly to flying a multicopter. WingtraOne will keep it's position if you do not touch the sticks. Likewise it will move according to your control stick input. Cruise You can fly the 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. Takeoff To take off manually, you need to go through the safety checklist first (you can leave out the mission planning), place WingtraOne on ground at a safe distance of 5 meters or more to any person including yourself, and click to "Start in Assisted Flight Mode" and move the slider to the right. Always recapitulate your control input options (see remote control) before taking off. Once you clicked "Start in Assisted Flight Mode" on the tablet, you can take off by holding the left stick (4.) 2 seconds on the maximum value. Let the stick go back to center during take-off to gain control over the aircraft . WingtraOne will take off, hold position 2 meters above ground and await your command input.
  • Page 46 Interactions & Assisted Mode It is recommended that you always setup a proper Flight Plan and start the flight by clicking on "Start Flight Plan". You can take over at any time during the flight (right after takeoff, in cruise, or before landing). Transition Use the transition button (6.) to transition from hover to cruise or vice versa. Forward-transition (hover->cruise): Make sure you are in 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 meter before you reach the point on which you want to hover. Always engage back-transition in a safe distance and altitude margin to 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 the aircraft to its intended landing position. Once you are above your landing spot, push the left stick (4.) hard down (really to its minimum!). The aircraft will use its distance sensor to detect landing and switch-off the engines at 10cm distance above ground. Remote Control...

  • Page 51: Failsafes

    Failsafes Failsafe Scenarios There are several scenarios where the 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.
  • Page 52 Failsafes You can take over manually during Return-to-Home by switching to Assisted Mode. Standard Return-to-Home Procedure The WingtraOne flies back to the loiter circle at it's current flight altitude and performs the planned landing. In case the WingtraOne is less than 60 meters above Home (RTH altitude), it climbs to 60 meters (RTH altitude) before flying back to the loiter circle. In case RTH is triggered when the WingtraOne is in hover but not yet near Home, it transitions into forward flight. The RTH altitude can be adjusted under settings --> safety --> Return to Home settings (you need to be connected to the WingtraOne to get access to the safety tab). Hover Near-Home Return-to-Home Procedure If RTH is triggered when the drone is within 80 meter distance to Home and in hover flight regime, it won't transition into forward flight. If the WingtraOne is below 20 meter altitude, it will rise to 20 meters, hover back to Home and land. If the WingtraOne is above 20 meter altitude but below 120 meters (2*RTH altitude), it will hover back to Home at current altitude and land. If the WingtraOne is above 120 meters (2*RTH altitude), it will transition into forward flight, fly to the loiter circle, and perform the planned landing. Return-to-Home without Flight Plan We recommend to set up a flight plan for every flight, even if you only want to fly the WingtraOne manually in Assisted Mode. In the special case of flying without a flight plan, the WingtraOne is not given a loiter circle. Therefore RTH works as follows: RTH Procedure without Flight Plan The WingtraOne will fly back to Home at current altitude, perform the back transition, hover down and land. In case the WingtraOne is less than 60 meters above Home (RTH altitude), it climbs to RTH altitude before flying back to Home. In case RTH is triggered when the WingtraOne is in hover but not yet near Home, it transitions into forward flight. Hover Near-Home RTH Procedure without Flight Plan If RTH is triggered when the drone is within 80 meter distance to Home and in hover flight regime, it won't transition into forward flight. If the WingtraOne is below 20 meter altitude, it will rise to 20 meters, hover back to...
  • Page 53 Failsafes Home and land. If the WingtraOne is above 20 meter but below 120 meter altitude (2*RTH altitude), it will hover back to Home at current altitude and land. If the WingtraOne is above 120 meter altitude (2*RTH altitude), it will transition into forward flight, loiter down to 60 meters (RTH altitude), perform the backtransition, hover down and land. Warning Warnings are issued acoustically and visually on the tablet. The mission can still be continued, but caution is advised depending on the foreseeable flight plan of the plane. Land on Spot / hover down This is the most extreme failsafe, as it forces the drone to perform a backtransition and land on the spot where it is at currently. It is triggered on GPS loss, or if battery voltage drops very low. If it is triggered by the battery, you can take over manually by switching to Assisted Mode. If triggered by GPS loss you cannot, as Assisted Mode does not work without GPS. Troubleshooting Known Issue: WingtraPilot does not reconnect to the WingtraOne after the telemetry was unplugged If the usb connection between tablet and telemetry is disconnected hardware-wise, WingtraPilot is not able to regain connection automatically. If this happens, reconnect the telemetry to the tablet and press the "disconnect" button on the top right of the screen. This first disconnects the connection and immediately after lets WingtraPilot regain the connection to the WingtraOne.

  • 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). A: Section for the Geotag Download. B: Section for the Geotagging itself. Steps to Geotag your Images Step 1: Download Geotags After landing, WingtraPilot starts downloading the geotags automatically and displays the progress:...
  • Page 55 Geotagging Be patient and wait until the download succeded. If the download fails, click on "retry" and walk towards the WingtraOne to get better connection. Open the geotagging menu once the download succeded and see if you got the information "Success: Geotags are downloaded successfully" (A). If you do not see the feedback, check if you can find your flight in the list under "Select a flight" (B). The flight is named after date_takeofftime. If it is not in the list, click on "Download" (A) to start the download again. Step 2: Geotag your Images on the Tablet Power off the WingtraOne, get the SD card from the camera and insert the SD card to the tablet. Enter a project name, select the correct (newest) flight out of the list, choose the directory on the SD card containing all images as image directory, and click on "Start Tagging" (B). 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 30 minutes). WingtraPilot creates a folder in the image directory (on the SD card) containing the original images, the tagged images, the mission 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.
  • Page 56 Geotagging Do not inspect the images during geotagging. Geotagging can fail if you open the images in another app during tagging. If that happens, restart the 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 the WingtraOne, re-insert the SD card to the camera. Results of Geotagging on the SD Card As a result you get a folder date_time_projectname/ in the image directory on your SD card. It contains the following objects:...
  • Page 57 Geotagging /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. 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" 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 the 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 drone, contact the Wingtra Support. It is possible that something with the triggering is not working as expected. 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:...
  • Page 58 Geotagging 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.
