G-LOC has resulted in a number of fatalities in which the aircraft and crew are lost. There is a need for high-G training and this can be accomplished in a man-rated centrifuge training system. Such systems are made by AMST Systemtechnik in Austria (Austria Metall SystemTechnik), the Environmental Tectonics Corporation (ETC) and in the USA.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. Man-rated centrifuges are made by AMST Systemtechnik in Austria (Austria Metall SystemTechnik), Latacoere in France, the Environmental Tectonics Corporation (EYC) and Wyle Laboratories in the USA.
