Abstract:

The ability to tack approach guidance position and speed to a low decision height 50 feet when performing a steep instrument approach 6 to 9 degrees in a rotorcraft clearly has a profound effect on the success of the approach. This report describes a preliminary attempt to define approach tracking standards for such approaches and includes a systematic data base upon which such standards can be based. This data base was generated in a flight experiment in which qualified rotorcraft certification test pilots evaluated the suitability of arriving at the decision height with various combinations of approach tracking error. The magnitude of tracking errors that are compatible with satisfactory pilot workload in the transition to hover and landing is well defined and tracking within these error bounds is clearly within the limits of current technology. The experiment was performed on the National Research Council of Canadas Bell 205 Airborne Simulator.
