This standard sets forth general philosophy and design guidance for using aircraft avionics equipment in simulators. Its goal is to improve simulator training by providing a better understanding among avionics designers, simulator designers, airframe manufacturers and airline simulator users in the use of aircraft avionic equipment in flight simulators. Full flight simulator, cockpit procedure trainer, cockpit system simulator or fixed base simulator, part task trainer (e.g., flight management system trainer), and maintenance training simulator guidance is included.
