This invention features a prone pilot's couch conformable to the front of the pilot's body, relieving his arms of the need to support the body; twist- and pull-handgrips placed to the sides of the pilot's body for convenient control-surface actuation; a helmet brace for positive-g flight maneuvers; passive shoulder braces which confine the chest to the pilot's couch in all flight attitudes, when forward exertion is applied by the legs; and channels conforming to three sides of the pilot's legs, having a lip or shelf which protrudes outward from a bracing area between the pilot's legs, for support during inverted flight maneuvers, forward exertion being applied by the legs.
