A number of external loads varying in weight (up to 4,000 pounds), size, and aerodynamic characteristics were lifted, flown, and released using the UH-1D Helicopter equipped with the standard cargo hook and the Universal Cargo Hook. All loads were released using the electrical release switches and then the manual cargo release pedals. Selected loads of various sizes and weights were released free-fall using the electrical released switches and then the manual cargo release pedals. Damage to, or problems encountered with, the standard cargo hook or the Universal Cargo Hook were recorded and reported. The time to effect cargo hookup, the difficulty of operation, and malfunctions were recorded for each load. Data were compiled on a comparative basis. (Author)
