I operate a rather professional fixed wing drone which requires pre-flight planning via an app and doesn't support direct control besides instant flight abortion and "return to landing zone" command.
Due to the fixed wings the covering of an area of interest includes U-turns at the end of each pass. These U-turns make things a bit complicated when it comes to flight planning, since they "collide" with a wind turbine. I was wondering, how much distance I have to keep. My location is Germany.
Flying above the obstacle is no option, since the drone is only registered in the open category, hence the maximum flight level is 120 m above ground.
