Energy expenditure was determined by analysis of expired air collected from 21 engineering test pilots on 18 flights in three types of cargo aircraft, one jet-powered, and a helicopter. Samples were taken in the aircraft while preparing for flight, during routine flight, and during simulated emergency flight. Mean value for energy expended in routine flight was 49.3 kcal/sq m hr, not significantly different from the 47.7 kcal/sq m hr expended during preparation for flight. During emergency procedures energy expenditure rose to 70.2 kcal/sq m hr. These values are not markedly different from values estimated for World War II aircraft. There was no significant difference in energy expended by pilots with extensive experience in the aircraft as compared to pilots with little experience in the aircraft. Neither was there strong evidence of hyperventilation under any flight condition. These data suggest that less energy is expended in preparation for flight and routine flights but more energy is expended during emergencies in the jet than in the helicopter or propeller aircraft.
