An environmental test was conducted in the Climatic Laboratory, Eglin Air Force Base (AFB), Florida, to determine the adequacy of the OH-58A helicopter for its intended use in extreme temperature environments. The pilot's body temperatures was recorded during the test. The testing consisted of 11 data runs for a total of 13.1 hours. The aircraft is generally acceptable for operation between 0 and 105 F. Operation of the aircraft above 105 F is limited by restriction of power available because of turbine outlet temperature limitations and by reduction of the pilot's ability to perform his required tasks because of fatigue. Operation of the aircraft below 0 F is limited by four deficiencies.
