ABSTRACT:
A control system for an anti-G suit for aircraft pilots anticipates G-forces before they are incurred. The system has an available load circuit which receives the actual airspeed signal and computes an available load factor. The system is connected to the command stick of the pilot. The signal from the command stick is multiplied by the available load factor to provide an anticipated G-force. A selector monitors the actual acceleration with the anticipated signal and passes the higher of the two to a valve. The valve controls air pressure leading to the anti-G suit.
