This report presents the results of a flight test program conducted to quantitatively and qualitatively verify the contractor's single-engine height-velocity curve and to determine compliance with MIL-H-8501A, Helicopter Flying and Ground Handling Qualities; General Requirements for. The results of these tests verified the height-velocity characteristics previously established by the contractor. Because of limitations imposed by the tail boom configuration, touchdown speeds consistently exceeded the 15-knot maximum allowed in MIL-H-8501A. Since all HH-53C single-engine height-velocity testing has been conducted at sea level, it was recommended that further testing be done at altitude. (Author)
