The present invention relates generally to a system for deploying a parachute during ejection of an occupant from a disabled aircraft, and more particularly to a fail-safe means of sensing airspeed in such a system. It is a general purpose and object of the present invention to provide a simple, yet effective airspeed sensor, used in a system for deploying a parachute during ejection of an occupant from a disabled aircraft, which stores peak dynamic pressure in order to selectively delay parachute deployment as a function of airspeed and altitude at ejection.
