ALLFlight: Assisted Low Level Flight and Landing on Unprepared Landing Sites

Abstract

DLR’s internal ALLFlight project (Assisted Low Level Flight and Landing on Unprepared Landing Sites) involves the research on helicopter pilot assistance systems that can assist the pilot through all phases of flight. The respective ALLFlight-system covers take-off, intermediate low level flight and landing on unprepared sites in the presence of obstacles and in poor visibility. This article outlines the implementation of the full-scale pilot assistance system into DLR’s Active Control Technology/Flying Helicopter Simulator (ACT/FHS) test bed. The ALLFlight pilot assistance system will provide the opportunity to test the full process, from sensors to data fusion and trajectory planning, using modern flight control techniques in real time in real situations during flight tests. Needless to say, but it is likely that the results of the ALLFlight research will also play a key role in HEMS in the future.
