Safety Parameters

A drone is a tool for professionals that can be a safety risk if not used properly. Make sure you always respect the limitations of your system to ensure the safety of material and people.

WingtraPilot features a couple of safety parameters to ensure safe operation throughout the entire operation. The parameters give you the possibility to influence the automatically triggered RTH scenarios described in Return to Home.

The safety parameters are accessible on the top right during mission planning via the drop down menu below the Flight Plan information.


Before starting a flight, one can adjust the parameters. These parameters are not saved to the flight plan and they required adaptations after each power cycle / flights. Keep in mind the following considerations:

Geofence radius around Home

  • Defines the maximum allowable distance from Home in the particular mission.
  • Prevents a fly-away of the WingtraOne beyond this distance.
  • When creating or opening a flight plan the maximum radius is set to 1200 m, which corresponds to the maximum visual line of sight.

Geofence altitude above Home

  • Defines the maximum allowable altitude above Home in the particular mission.
  • Prevents a fly-away of the WingtraOne beyond this altitude.
  • Per default the maximum altitude is set to 400m before each take-off.

Minimum RTH altitude above Home

  • Defines the minimum altitude on which WingtraOne returns to home in a RTH.
  • If current altitude is lower than the defined Minimum RTH altitude, WingtraOne will climb to the set value in a loiter circle and only then fly directly Home.
  • Per default Minimum RTH altitude above Home is set to 60m before each take-off.
  • Adapt Minimum RTH altitude to the mission requirements in particular in difficult terrain and when using Ground elevation offsets.

Connection loss timeout

  • Defines time span after which WingtraOne will execute an RTH if both RC and telemetry connections are lost.
  • Note: Since no telemetry connection is available, you will not receive feedback on the state of WingtraOne.
  • Per default Connection loss timeout is set to 10s before each take-off.
  • Adapt Connection loss timeout to your mission requirements. For flights beyond visual line of sight and with obstacles in the direct line of sight increasing the timeout might be required to ensure that WingtraOne follows and completes the defined Flight Plan.
Without RC or telemetry connection you have no means of interacting with your WingtraOne. Do not increase connection loss timeout unnecessarily and make sure not to violate your local law.

Minimum ground clearance

  • Defines the minimum distance between the flight altitude and the terrain altitude.
  • Important: If the minimum ground clearance parameter is higher then the defined altitude above Ground, the flight altitude will adjusted to match the ground clearance parameter.
  • Use the minimum ground clearance parameter to account for trees, houses and obstacles. Set the parameter to have a margin to the highest obstacle in the flight area.
  • Note: The minimum ground clearance parameter accounts for uncertainity in the elevation data ~which is approximately +- 20m.
