ASSISTED LANDING FOR HELICOPTERS IN CONFINED AREAS

Kurzfassung

This paper describes the implementation of a computer-based approach planning for manned helicopters in confined areas. The algorithms developed consider the procedures of pilots during the approach planning. Thus approach trajectories are generated which not only regard flight limitations, obstacles, terrain and airspace restrictions but also the pilot’s individual preferences and approach criteria. These factors depend on the flight missions and/or the pilot’s experience for instance. To get an idea which criteria are important and have to be regarded by the approach planning, a comprehensive survey among 80 air rescue pilots was conducted. Based on the results different types of approaches were identified which still have to be adapted to meet each individual requirement of the helicopter pilot. This adaptation can be conducted by the current pilot or the operator of the helicopter. The generated approach trajectories are evaluated by pilots.
