This paper describes the design and capabilities of a noninvasive system to record the superficial temporal artery (STA) pulse pressure during diving scenarios in pilots. The Piezoelectric Pulse Pressure Monitoring System (P3) records the "best" waveform from an array of piezoelectric benders in contact with the skin above the STA during +1 Gz acceleration and then continuously monitors it during +Gz acceleration for determination of G-LOC conditions. Results indicate that P3 may be used in a cockpit environment and may be the controller in an aircraft autorecovery system.
