A new look at the loss of consciousness experience within the U.S. Naval forces.
Two surveys on the incidence of G-induced loss of consciousness (G-LOC) in U.S. Navy aircraft have been completed. Questionnaires returned (981) indicated an incidence rate of 12.2% in the first survey. A slightly higher incidence rate was found in the second survey based on the 2,459 questionnaires returned. Results indicated that G-LOC is a significant problem in naval aviation in older as well as newer generation aircraft. Age, height, and weight of respondents did not appear to be related to incidence of G-LOC. Results indicated a need for improvement in the anti-G protective system and its use. Different forms of physical fitness training may differentially influence G-tolerance.
