An AATD requires a self-centering yoke and rudder pedals, accurate power controls including mixture and propellers, primary flight displays for a glass airplane, flaps, trim, communication and navigation radios, transponder, landing-gear handle and a few other items. And, of course, the simulator must fly like the airplane, or at least very similarly, depending upon how it’s used. Then there are flight-training devices and the full-flight simulators. An FTD recreates a specific aircraft type, but might not include full motion. Full-flight simulators are categorized as level C or D.
