Methodological Research in the Field of Civil Aviation Safety.

In order to promote the application and development of civil aviation safety (CAS) in the field of safety and enrich the theoretical system of CAS research, the methodology of CAS was studied. The definition of CAS was reconstructed, its connotation was explained from four aspects, and its research object was clarified. This paper discussed the mechanism of CAS, that is, to maintain system security through the establishment of safety prevention and control system (SPCS), and explained the research content of CAS from theory and technology application. Five principles and applicable methods for CAS research were summarized. In addition, it put forward the general procedure of CAS research, explained the specific content and implementation method or basis of each step. The research results show that the methodology of CAS is a systematic theoretical system with certain guiding significance, combined with the mechanism, research content, research principles and methods, and research procedures of CAS.
