G-force-training

G-induced loss of consciousness (abbreviated g-LOC). is a condition where a person loses consciousness because g-forces primarily acting along the length of the body move the blood away from the brain to the extent that consciousness is lost. Incidents of acceleration-induced loss of consciousness have caused fatal accidents in aircraft capable of sustaining high-g for considerable periods such as the BAe Hawk, F-16 Falcon and F/A-18 Hornet. As a result, air force training facilities in many countries now include man-rated centrifuges for high-g training in a safe environment
