Abstract

In order to effectively identify the key causative factors of civil aviation flight accidents, and establish a forward-looking effective prevention mechanism for flight accidents. Firstly, Corrected SHELLO model is established to classify the causes of civil aviation accidents in China (2015-2019) based on the integration of SHELL analysis model and Reason organization system concept. Secondly, in view of the randomness and uncertainty gray characteristics of the flight accidents inducing factors, the improved entropy gray correlation algorithm is established for the purpose of importance recognition, which combined with the characteristics of the data sample of inducement classification. Finally, the improved entropy gray correlation algorithm is used to identify and rank the key causative factors of flight accidents. The results showed that the flight accidents crucial causative factor is the human factors which we should pay more attention including the pilot perceptual errors, skill-based errors, decision errors and violation main factors, environmental and organizational factors also play an important role in inducing flight accidents, including complex terrain for approach landing and poor safety management mechanism factors. The method has great practical significance for identifying critical causative factors of flight accidents and improving flight safety.
