To solve the problem of risk identification and quanti-tative assessment for human-computer interaction(HCI)in com-plex avionics systems,an HCI safety analysis framework based on system-theoretical process analysis(STPA)and cognitive reli-ability and error analysis method(CREAM)is proposed.STPA-CREAM can identify unsafe control actions and find the causal path during the interaction of avionics systems and pilot with the help of formal verification tools automatically.The common per-formance conditions(CPC)of avionics systems in the aviation environment is established and a quantitative analysis of human failure is carried out.Taking the head-up display(HUD)system interaction process as an example,a case analysis is carried out,the layered safety control structure and formal model of the HUD interaction process are established.For the interactive behavior"Pilots approaching with HUD",four unsafe control actions and 35 causal scenarios are identified and the impact of common performance conditions at different levels on the pilot decision model are analyzed.The results show that HUD's HCI level gra-dually improves as the scores of CPC increase,and the quality of crew member cooperation and time sufficiency of the task is the key to its HCI.Through case analysis,it is shown that STPA-CREAM can quantitatively assess the hazards in HCI and iden-tify the key factors that impact safety.
