PLUS GZ PROTECTION IN THE FUTURE - REVIEW OF SCIENTIFIC LITERATURE

To reduce the incidence of G-induced loss of consciousness and enable pilots to operate their aircraft at higher levels of performance, anti-G protection must be improved. A G-suit and the anti-G straining maneuver will likely remain essential components of any anti-G system, but several methods potentially increasing G-tolerance have been investigated that could supplement the protection afforded by these traditional techniques. Pharmacological agents are of no benefit, while breathing carbon dioxide, shown to improve G tolerance, is impractical. Positive pressure breathing has so convincingly improved G-protection that it will become an operational procedure in the immediate future. The benefits of the G-suit have been augmented through greater coverage of the lower body and efforts are also aimed at more responsive G-valves. Altering body position to shorten the heart to head hydrostatic distance adds directly to the protection offered by the other procedures but can impair vision and must wait until the cockpit is redesigned.
