From what I understand, the CPI is an externally-mounted transmitting device, originally developed for use on military aircraft, which was designed to jettison a fraction of a second after impact - thereby throwing itself clear of the aircraft. This prevented it from sinking, being buried or being destroyed by fire while at the same time allowing it to remain close enough to the wreck to aid location by emergency services.
