Operational Requirements for Avoidance and Eventual Elimination of Gz-InducedLoss of Consciousness (G-LOC) in Flight

摘要

On the basis of the physiology involved in G-induced loss of consciousness (G-LOC) and because of the very high cost in pilot lives and their airplanes due to G-LOC, three operational requirements are described: (1) a noninvasive on-line real-time recording of arterial pulsations at brain level should be a mandatory requirement for every human centrifuge exposure to high G accelerations that carry an appreciable likelihood of loss of vision and/or consciousness. A similar system should be mandatory for every pilot when performing high-G air-to-air or air-to-ground combat maneuvers both in training and in actual combat; (2) a physiological forewarning system based on arterial pulsations at the head level coupled with a last resort automatic airplane recovery system should be installed in all advanced fighter aircraft; (3) A G-LOC avoidance system based on a 9-G or greater activated timer should be installed in all advanced fighter aircraft. Failure of pilot response should then activate a follow-on automatic airplane recovery system. For future operations, an advanced high-G cockpit for flight in the fully horizontal position should be developed.
