Microprocessor controlled post ejection sequencer
 A self contained, self powered microprocessor controlled aircraft ejection seat escape parachute deployment sequencer which can handle problems caused by high altitudes into the stratosphere and by high speeds above Mach 1, and which will deploy the parachute, based on seat mounted pitot tube and ambient pressure readings plus stored data, when speed and altitude are at human physiologically acceptable levels. Many failsafes to cope with unusual conditions, and additional features are also included.
