Discussion of acceleration protection measures should be based on analysis of relevant accident data, including determination of high risk aircraft, G profiles, and pilot descriptions. There were 18 accidents (14 fatalities) attributed to G-induced loss of consciousness (G-LOC) in the United States Air Force (USAF) from 1982 through 1990. All 18 accidents occurred during single crewmember sorties, for an average rate of 2.1 per million single-seat flying hours (pmfh). The average G-LOC accident rate for 1982-4 was 4.0 pmfh, decreasing significantly to 1.3 pmfh for 1985-90. This decrease is associated with the USAF initiation of an anti-G-LOC training program. We reviewed accident records for G-LOC cofactor data and compared them to normal data for USAF pilots for age, height, weight, systolic and diastolic blood pressures, heart rate, total flying time, and aircraft-specific flying hours. Only for systolic blood pressure (higher) and aircraft-specific flying hours (shorter) were the mishap pilots significantly different from other USAF pilots. We found no evidence to support weight training vs. aerobic training, missed meals, or heat in causing G-LOC accidents. Thus the mishap pilots appeared to be a representative cross section of USAF pilots with respect to personal variables. More significant factors appeared to be G duration, G magnitude, use of G trousers, and experience in assigned aircraft.
