Abstract:
Flight tests using left turns to final were conducted in 1989 and 1990 at the Federal Aviation Administration FAA Technical Center to aid in answering questions concerning curved approaches to a heliport under visual meteorological conditions VMC. Those questions included protected airspace within the curved segment, the most feasible angle of turn, and minimum final approach segment. Additional tests using the FAAs Sikorsky S-76, were conducted at the FAA Technical Center in 1992 using right turn to final. Results will be used to help refine the airspace requirements for curved approaches. Three turn angles were examined, 45, 90 and 180 degrees each with three different final segment lengths, 800, 1200 and 1600 feet. A groundbased tracking system was used to track all maneuvers. This report documents the results of these flights. The test procedures, evaluation methodology, and technical and operational issues are discussed. Analysis of pilot performance, as well as pilot subjective input, are provided. Conclusions are drawn that address the airspace, turn angle, and final segment issues. The results will be considered in future modifications to the FAA Heliport Design Advisory Circular, AC 1505390-2. Curved approaches, Approach surface, Final segment, Heliport.
