Abstract: The safety of the civil aviation business system is very important because it is a necessary condition for civil aviation enterprise to run. Formal verification method is an important approach to insuring system safety. In this paper, firstly, the fault tree analysis technology is introduced to analyze the safety requirements and the new ABPD modeling language is promoted. Secondly, six kinds of safety properties are defined through analyzing the model. Thirdly, safety verification is achieved through graph search algorithm and the concrete implementation of the algorithm is provided. Lastly, the experiment results explain the completed verification process and the validity of the method.

Key words: civil aviation business system, fault tree analysis technology, ABPD modeling, safety verification, model verification
