Study On Evaluation Method Of Civil Aviation Hidden Danger

Hidden danger can lead to accidents. As an important method of preventing accidents,eliminating hidden danger has been paid much attention in recent years. Civil aviation industry is promoting hidden danger screening and control actively. However, there is no reference method for the taxonomy and evaluation of hidden danger at the industry level.Taxonomy and evaluation methods of civil aviation hidden danger are mainly studied to solve the management issues existing in the civil aviation industry, which can provide reference for the identification and evaluation of hidden danger in civil aviation.At first, the research status of hidden danger are analyzed. Based on the analysis of actual investigation, four issues about hidden danger management which exist in the civil aviation industry are pointed out. By analyzing common hazard classification and risk evaluation methods, and distinguishing accident potential from hidden danger, hidden danger from hazard and risk, the theoretical foundation for studying classification and evaluation methods is established. Then, by analyzing similarities and differences between hidden danger management systems which respectively belong to State Administration of Work Safety and Civil Aviation industry, the method to integrate the two systems is proposed, which provides guidance for solving issues about implement of the two management systems inside civil aviation enterprises. Meanwhile, hidden dangers which cause Civil Aviation Accidents /Incidents from 2004 to 2013 are statistical analyzed, and the Crew and the Bird strike are taken for instance to do the analysis of hidden danger. It provides basis for classification and evaluation of hidden danger. On the basis of considering classification standard of hidden danger in other domestic industries, as well as complying with civil aviation laws and regulations, a civil aviation hidden danger index system is developed after expert discussion.Finally, advantages and disadvantages of common hidden danger evaluation methods are analyzed. Combining with characteristics of civil aviation safety hidden danger, it builds civil aviation hidden danger evaluation model by improving two-stage evaluation method of hidden danger. The applicability of the evaluation method is validated by examples in civil aviation industry.In conclusion, taking civil aviation hidden danger as the research object, it analyzes thetwo hidden danger management systems and provides reference for the implement of civil aviation hidden danger management. The civil aviation hidden danger index system and civil aviation hidden danger evaluation model provide reference for the identification and classification of civil aviation safety hidden danger, which is hoped to provide support for hidden danger screening and treatment work in civil aviation industry.
