摘要：

The airborne head-up display (HUD) system can greatly improve the success rate of take-off and landing in bad weather and has become a safety promotion technology promoted by the civil aviation administration of China. By constructing a special Ⅰ/Ⅱ approach scene using the HUD system under low visibility, the system-theoretic process analysis (STPA) is used to identify potential unsafe control actions in this scenario. The verification and scenario analysis is carried out through strict formal language, and a scenario analysis framework containing 21 general factors is presented. In order to make up the shortcomings of lacking quantitative analysis, the Bayesian network is introduced to calculate the probability of unsafe control action, and the STPA-Bayes safety analysis and evaluation model is proposed. The results show that this method can effectively identify and analyze potential hazards of the system, reduce the influence of human factors on the results, and provide supports to the safety analysis of the airborne display system. © 2020, Editorial Office of Systems Engineering and Electronics.
