Title of Paper:Flight Test Risk Mechanism with Man-Machine-Environment System of Civil Aircraft

Journal:Lect. Notes Electr. Eng.

Abstract:The processes of flight test are compulsory for manufacturers and authorities to assess the airworthiness of civil aircraft. The test risk exists in all kinds of systems and parts. It is significant to identify test risk for safety. The process of test risk management has been established including identifying potential test risk modes, selecting crucial test risk modes, and listing major inspection projects. The deeper risk mechanism in each flight test project has been determined by analyzing multi-failures. The failure situations include: (1) the failures are independent of each other; (2) the catastrophic consequences are caused by independent failures; (3) the dependent failures are caused by others; (4) the dependent failures belong to common mode failures. The causal chain and common mode failure has analyzed failures reasons; the fault tree and events chain has obtained conditional probability of unacceptable consequence; the expanded fault tree and Markov method have improved risk accuracy. According to the airworthiness requirements, the acceptance of corresponding risk level from major inspection project can be determined to decrease test risk, comply with regulations of airworthiness. © 2019, Springer Nature Singapore Pte Ltd.
