All U.S. military and air carrier aircraft are required to have on board Crash Position Indicator/Crash Survivable Flight Data Recorder/Crash Survivable Cockpit Voice Recorder (CPI/CSFDR/CSCVR) systems. All air carrier aircraft use nonejectable CPI/CSFDR/CSCVR systems. U.S. and Canadian military aircraft use both ejectable and nonejectable CPI/CSFDR/CSCVR systems. Ejectable systems are used on Navy, Marine Corps, and Coast Guard aircraft, primarily because of their overwater mission. Ejectable systems are more complex that nonejectable systems. The reliability, maintainability, and suvivability record for both ejectable and nonejectable systems ranges from poor to excellent depending on system design, configuration, and testing. The Search and Rescue (SAR) record for ejectable systems is excellent while the SAR record for nonejectable systems has been relatively poor. The weight, volume, and power requirements for ejectable systems are generally less than for nonejectable systems. The System Safety of all systems is excellent except for the Mortar type (personal hazard if inadvertently ejected on the ground). The acquisition cost of ejectable systems are generally greater than for nonejectable systems. Ejectable CPI/CSFDR/CSCVR systems should be used on aircraft that operate over water. All other aircraft could use either ejectable or nonejectable systems.
