Verification and test case development method based on civil aircraft operation scenario

Due to the characteristics of civil aircraft system integration, requirement-based testing cannot fully verify the complex cross-linking between multiple systems. With the gradual deepening of research on flight process in recent years, method of verification based on scenarios has been applied to test verification process of civil aircraft. This paper studies the verification process based on typical operation scenarios of civil aircraft. A method for establishing behavior model of operation scenario based on SysML is proposed. The model covers key parameters and behavior information of scenario which can support closed-loop simulation of aircraft. In addition, the method of generating test cases based on SysML model is optimized, and a set of use cases suitable for scenario-based testing is formed through the combination of test data and path. This paper takes the ground proximity warning function verification scenario as an example to show the method of scenario modeling and test case development, which can be applied to test verification process of operation scenario, and supports the closed-loop simulation and testing. © 2021, Shanghai Jiao Tong University.
