Rudder pedal and stick are important control devices of civil aircraft, different position was required to different stature pilot, unreachable or discomfortable control posture were caused by unreasonable position, and then fatigue was caused, flight safety was affected directly or indirectly. 13 Chinese civil pilot simple human models were positioned to same Design Eye Position and most comfort pilot posture such as 5%, 10%, 15%, 20%, 25%, 30%, 50%, 70%, 75%, 80%, 85%, 90% and 95%, by regression analyzing to their position of hand and foot, optimization adjust route of rudder pedal and stick to pilots different in stature were gained. The methods and conclusions here can be used to instruct the ergonomics design of rudder pedal and stick, what is good for the pilot to drive comfortably, safely, and effectively.
