Relationship between acceleration and time at maximum G required to produce symptoms of gray out and black out.
-induced (centrifugal acceleration) loss of consciousness. A condition that occurs when the g
loading is above 5 or 6 continuously for more than 5 to 7 s. Unconsciousness follows because of the temporary stoppage of the blood supply to the brain. However, this phenomenon does not occur if the buildup of g
is very rapid only momentarily, as during ejection. The chances of G
-LOC can be minimized by use of anti-g
maneuvers, and a higher level of physical fitness. See also anti
