  • Title: Converging research on +Gz-induced loss of consciousness.
    Author: Whinnery JE.
    Journal: Aviat Space Environ Med; 1988 Jan; 59(1):9-11. PubMed ID: 3281648.
    Abstract:
    The G-induced loss of consciousness (G-LOC) hazard can be reduced either by preventing its occurrence or shortening the period of incapacitation. The latter requires an understanding of this period of incapacitation. Two types of G-LOC occur: Type I is short duration and without convulsive type movements; and Type II is longer and with convulsions. Psychological suppression (denial) by pilots that G-LOC had occurred appears to be an important problem in reporting surveys and flying safety. Auditory and visual types of sensory stimuli to reduce the period of incapacitation are discussed. Recognition by the pilot that G-LOC has occurred appears to decrease incapacitation times and should be considered part of G training. Methods of developing an aircraft recovery system after G-LOC has occurred in pilots is considered a viable approach and is examined. Converging on the G-LOC problem by both, reducing its incidence as well as its duration appears to offer an additional dimension in the approach towards solving this important operational problem.
