The objectives of the test were to determine the airworthiness and to define the performance characteristics and flying qualities of the helicopter. Test Results, where appropriate, were compared with previous test results of the standard UH-1B. Tests were conducted at Edwards Air Force Base, California, and at remote test sites in California and Colorado from 19 May 1965 through 30 April 1966. Total aircraft flight time was 336.30 hours. Quantitative helicopter performance was defined for hovering, takeoff, climb, level flight, and autorotation. Stability and control characteristics were investigated for varied conditions of altitude, airspeed, center-of-gravity location, and gross weight.
