Abstract

In order to solve the problem that the risk of human-computer interaction behavior caused by the application of new technologies in avionics systems is difficult to be covered by existing safety assessment methods. The airworthiness requirements for human-computer interaction of avionics systems were sorted out. The hierarchical emergent model of airborne systems was constructed based on the emergence perspective. The STPA method was introduced to the identify and analyze the unsafe control action(UCA), and the human-computer interaction risk safety analysis process was formed. Taking the human-computer interaction behavior of airborne flat screen display system in the approaching process as an example, the human-computer interaction task decomposition is completed. The results show that based on the emergence perspective, the human-computer interaction risk of airborne systems can be effectively identified by constructing the security control structure, and the mitigation measures against various risk-causing factors can effectively reduce the risk impact in the system design stage. © 2022 China Safety Science Journal.
