Study on the Airworthiness Certification of Human Factor in Flight Test for Civil Aircraft

With the development of system reliability for aircraft, human error is becoming one of the main factors that leading to flight accidents, which has been a key and difficult challenge for the design and airworthiness authorized departments. This paper analyzes the airworthiness certification process based on CCAR 25, including the selection of regulations relevant to human factor based on SHELL model and T.E.S.T matrix, the means of compliance verification for experimental aircraft based on MOC5 and MOC6; the compliance test program is determined, and a data analysis example based on fuzzy evaluation method is shown. The thought for airworthiness certification of human factor and verification method proposed in this paper has been applied preliminarily in ARJ21-700, and it can provide the technical support for the design and airworthiness certification of human factor for other civil aircraft such as C919.
