Why Do Fighter Pilots 'Pass Out' Sometimes While Flying?

G-LOC, or gravity-induced loss of consciousness, is an extreme result of being subject to high G forces for sustained periods of time. Particularly common in high-speed ascents, the blood tends to pool in the lower portions of the body, completely depriving the brain. This results in a temporary loss of consciousness and, consequently, a catastrophic loss of control of the aircraft.

In order to increase their threshold for G-LOC, fighter pilots must routinely subject themselves to artificially created high G-force scenarios. This is aided by ‘human centrifuges’ that rotate at high speeds to simulate extreme in-flight situations. This acclimatizes pilots and reduces the risk of G-LOC during actual air time. While they can survive high G forces for very short intervals of time, they are trained to sustain up to 9Gs, although stunt pilots often push their limits to 12G.
