ALLFLIGHT: HELICOPTER PILOT ASSISTANCE IN ALL PHASES OF FLIGHT

The DLR internal project ALLFlight (Assisted Low Level Flight and Landing on Unprepared Landing Sites) deals with the development of a helicopter pilot assistance system, which assists the pilot through all phases of flight. The system covers takeoff, intermediate low level flight and landing on unprepared sites in the presence of obstacles and in a degraded visual environment. The paper describes the implementation of the full scale pilot assistance system into DLR’s Active Control Technology / Flying Helicopter Simulator (ACT/FHS) testbed. The unique ALLFlight full scale pilot assistance system gives the research establishment the opportunity to test the whole chain from sensors, via the data fusion and trajectory planning including active inceptors to modern flight control techniques in real time in the real world during flight tests.
