Abstract:

High automation in modern cockpits easily leads to pilots' automation complacency and reliance and then impairs pilots' automation awareness. Failure of automation awareness is one of the major factors influencing aviation incidents and accidents. By investigating the effect of task complexity on automation awareness and the causes of failure of automation awareness, it shows that the possibility of failure of automation awareness in the high-complexity task is higher than that in the low-complexity task and that insufficient attention allocation and automation complacency are two major factors contributing to the failure of automation awareness. It implies that it is hard for human being to detect automation failures and make effective operations when automation fails under high-workload conditions. Consequently,enhancing automation awareness is important for maintaining aviation safety.

Key words: complexity, human-automation interaction, automation awareness, automation complacency, aviation safety
