Loss of consciousness (LOC) during exposure to +Gz occurs in aircrew flying high-performance aircraft. This phenomenon is responsible for several USAF aircraft losses with accompanying loss of life. It has been recognized as a potential flying problem since 1938. Acceleration-induced LOC exhibits in 15- to 20-s periods of aircrew total incapacitation, amnesia, and clonic spasms. It can occur at relatively low G levels and without symptoms of loss of light (blackout). Operational anti-G equipment and methods are not completely effective in preventing LOC. A deficiency in the anti-G straining maneuver is considered to be the primary cause of G-induced LOC. Adequate G protection that would eliminate LOC as a serious problem for USAF high-performance aircraft operations must include supinating aircrew to a minimum seat back angle of 60 deg to 65 deg.
