Abstract
An aircrew support system for supporting a pilot's head, and optionally his torso, during high g maneuvers, enabling him to maintain his head in an upright position and thereby increasing his awareness of the situation at all times outside the cockpit comprises at least one head support line (3) adapted for connection between the pilot's head/helmet (4) and the seat (1), accelerometers for measuring the g force acting on the pilot/aircraft and a tension structure for applying a continuously variable tension to said support line of a magnitude determined by the magnitude of the current g force acting on the pilot/aircraft. The support system may include a restraint system, for restraining the pilot in a predetermined position during ejection and for disconnecting the support line on ejection.
