Model: 10002200-501

Properties:

A device which provides automatic activation, at preset intervals, of the aircraft crewmember ejection seat escape systems and subsystems. It activates immediately after the seat is ejected from the aircraft. It contains logic circuitry to select the best mode of operation for a full range of escape conditions based upon speed and altitude at the time of ejection. It also contains internal thermal batteries, when activated, provides power to operate timing circuits and initiate electrical impulses that actuate subsystem ballistic devices.
