Development of a Tunnel-in-the-Sky Display for Helicopter Noise Abatement Procedures

Kurzfassung

Research on helicopter noise abatement at DLR has led to the development of a pilot assistant display for following prescribed noise optimised landing procedures. An intuitive tunnel-in-the-sky display was chosen in order to reduce pilot workload during complex manoeuvres. Trajectory generation is performed partly during flight which allows the update of the displayed trajectory relative to the current helicopter position. Performance of the tunnel-in-the-sky display has successfully been demonstrated during ground-based simulator tests with two pilots.
