Abstract
An improvement is disclosed in a helicopter adapted to fly while moored to a ground station, being remote-controlled therefrom and having a device for automatic stabilization of the flight attitude, and in which the mooring cable is wound-on and wound-off of a cable drum by a drive device, the improvement comprising a stabilizer in the helicopter adapted to be switched to different operating ranges, and a switching device in the ground station coupled with the cable drum, the switching device being adapted to transmit signals for the stabilizer in dependence upon the wound-off length of the mooring cable.
