That makes no sense, the point of pressurising a G-suit is to physically press on the pilot&#x27;s lower body and drive blood towards the upper body, think adaptive high-pressure compression stocking.<p>Pressurising the cabin can have no such effect.<p>Plus the point of G-suit is high-G manoeuvres, not linear acceleration or deceleration: untrained humans can handle 17g eyeballs in and 12g eyeballs out <i>for several minutes</i> versus instants of 4~6 g along other axis, Stapp&#x27;s work demonstrated that properly restrained humans could walk away from 46G eyeballs out (decelerating while facing forwards)
