A variety of small fixed-wing aircraft are used by the military services to perform numerous utility tasks. The character of the noise encountered within the utility-type aircraft is described and illustrated. Noise envelopes are depicted for 14 aircraft powered by small reciprocating engines rated at less than 600 horsepower, 9 powered by reciprocating engines rated at 1200 to 1525 horsepower, and 8 powered by turboprop engines. In addition to general noise profiles representative of normal cruise, levels are shown for other phases of operation. The noise encountered within utility aircraft constitutes a significant auditory risk since personal ear protection (including headsets mounted in crash helmets) is not routinely worn in most of these aircraft.
