Before
commencing the flight, the pilot must check that it is safe to take off. If the
take-off and landing area is free of obstacles, the flight can be started. In
case of a multi-rotor unmanned aircraft, the unmanned aircraft is allowed to
climb to a height of approximately two meters. At a minimum distance of five
meters, the flight control checks are performed. For fixed wing unmanned
aircraft, these checks are performed on the ground.
