Abstract:
The Minimum Unstick Speed is the minimum calibrated airspeed at and above which the aircraft can safely lift off the ground,and is the key to determine the take-off characteristic speeds of civil transport aircraft. Turbopropeller powered transport aircraft uses propellers as energy output,and propellers should be considered in airworthiness verification phase.This paper studies the regulation requirements related to Minimum Unstick Speed,analyzes the characteristics of Minimum Unstick Speed,systematically gives the compliance methods,and analyzes the concerns during the review,including the key points and risk points. It can be used to guide the airworthiness review of Minimum Unstick Speed of civil transport aircraft.
