- Abstract
The head-up display system(HUD) is a key system for avionics that can improve operational safety of aircraft under low visibility. It is necessary to carry out complete safety analysis during development process. Traditional methods are difficult to capture hazards of interactions among components due to the increasing complexity of the avionics system. Therefore, the HUD system is analyzed by systematic theory process analysis(STPA), which pays more attention to interaction among components, and potential unsafe control actions are identified. Meanwhile, the formal model of HUD system is established and unsafe control actions identified are verified by the formalization tool based on Timed Automata———UPPAAL. Finally, a UPPAAL path algorithm is designed to search causes of unsafe control actions. The result shows that this method can identify the potential hazards of the system and analyze its causes effectively. It reduces the influence of human factors on the analysis.
