Return-to-home

Learn about the return-to-home RTH feature of WingtraOne.

RTH is triggered automatically as a failsafe scenario, or it can be triggered manually. Engage RTH if you want WingtraOne to come back and land autonomously. If RTH is engaged, WingtraOne will fly home on a path that is safe against terrain collision. 

Based on the terrain and your flight plan, WingtraPilot pre-computes a number of safe return-to-home paths before flight. Safe paths include flying backwards through already completed elements, flying forward towards the end of the planned flight, and available shortcuts within your airspace defined by the geofence and minimum and maximum height above ground parameters. In the air, the drone picks the most energy-efficient safe path depending on the current location and height of the drone and other factors like wind direction and magnitude.

As soon as RTH is triggered, the RTH path is displayed on WingtraPilot including:

  • the RTH point with a loiter circle
  • the safe RTH path
  • additional loiter points

More information like altitude changes is displayed in a pop-up. The detailed RTH procedure depending on the position of WingtraOne can be seen in the examples below.

The safe return to home path is not necessarily the shortest route.

In assisted flight mode with the RC, RTH will be performed in a straight line from the point it is triggered to home. The drone will fly straight home at its current altitude as long as that altitude is higher than a minimum of 60m above Home. Else the plane will rise first at the RTH point to 60m above Home and then return straight home.
