Abstract:

In order to reduce the operational safety risk of general aviation short-distance transportation in China, an accidents/incidents inducement analysis method based on ACE and BN was proposed. Firstly, 102 U.S.commuter flight accidents/incidents were analyzed, and a total of 7 categories and 19 causes were identified. Then, ACE formula was introduced to determine the priority of nodes, the K2 algorithm was used to construct the BN structure, and the maximum expectation (EM) algorithm was used to learn the network parameters, and the incentive analysis model of commuting flight accidents/events was established. Finally, the probability of each inducement was sorted and the sensitivity among inducements was analyzed. The results show that the probability of accidents/events caused by insufficient unit experience is the highest. The mechanical equipment is easily affected by bad weather such as rain and snow; weather factors and regulatory factors are highly sensitive to unit factors. Among them, bad weather will affect the normal operation of mechanical equipment such as wings, which in turn affects pilots' operation of aircraft. In adequate technical and safety training will affect the professional level and experience and skills of pilots and controllers.
