Research on flight safety of left boundary of general aviation aircraft based on airworthiness

Abstract

Stall/spin is the most serious safety problem faced by general aviation aircraft in left boundary of flight envelope. The statistics of stall/spin accidents show that, the catastrophic consequences of stall/spin cannot be avoided although the aircraft has the ability to recover from spin. In order to avoid the tendency of aircraft to inadvertently depart controlled flight, the construction method of a layered defense system for the safety of general aviation aircraft in left boundary of flight envelope is proposed by improving the pilot′s state awareness, enhancing the aircraft deviation resistance and reducing the damage of loss of control, which is based on the concept of "layered defenses", and analysis of revised stall/spin clause in the new FAR-23 airworthiness standards and the accepted compliance methods. The proposed method can help the general aviation aircraft better meet the requirements of the stall/spin airworthiness standards, and achieve the purpose of improving flight safety in left boundary of flight envelope.
