redoutenUK
redoutA temporary condition occurring because of the effect of negative g on the body, resulting in excessive blood pools flowing into the head and the face and the eyes becoming suffused. The vision is dimmed and the person experiences “redout.” A redout occurs at much lower g values than a gray-out or a blackout, is much more unpleasant, and the effects last much longer.
