Flight tests were conducted at an auxiliary landing field to examine the current heliport approach/departure surface criteria under hot climate and/or high altitude conditions and to verify or modify these surfaces, if appropriate. Data were collected using a Bell UH-1 helicopter for 7.125, 8.0, and 10.0 deg. straight-in approach surfaces. Also, straight-in departure surfaces of 7.125, 10.0, and 12.0 deg. were used. In addition to these procedures, the pilots were able to choose any angle of approach and departure. All maneuvers were tracked using an onboard Global Positioning System (GPS). The flight test and evaluation methodology are described. Also, technical as well as operational issues are presented. Statistical and graphical analysis of pilot performance along with a discussion of pilot subjective opinions concerning the acceptability and perceived workload, safety, and control margins associated with the procedures flown are also provided.
