Air Force Preliminary Evaluation of the UH-1N Helicopter
Abstract
Limited performance, flying qualities and systems tests were conducted during a 24.5 hour evaluation of the UH-1N helicopter for the purpose of determining the gross deficiencies of the aircraft. The flying qualities were generally satisfactory with the flight control hydraulic boost system on. With the hydraulic boost system off, however, the control forces were so high that a Cooper-Harper Rating of 9 was given to boost off flight. Hover and climb performance met or exceeded the predicted values for the conditions tested. The maximum allowable level flight speeds were easily attained. Specific range and endurance differed significantly from predicted values. Aircraft subsystems generally performed adequately, however, several major discrepancies were noted.
