PILOT PERFORMANCE DURING MULTIPLE FAILURES: AN EMPIRICAL STUDY OF DIFFERENT WARNING SYSTEMS

Dealing with a cascade of failures while maintaining process integrity, or dynamic fault management (DFM), is a dominant human task in various transportation modes. The way in which a warning system represents failures and the way in which the system contributes to failure management jointly determine the amount and type of cognitive work in which humans engage to manage these failures. In this study, pilot performance on 4 different commercial aviation warning systems was tested by measuring time and error rates in identifying root causes in a cascade of failures. All systems tested represent failures in the same basic way but differ in the kind of contribution they make to the failure management task. Human performance benefits accrued in systems that both provided guidance on what to do next and showed which systems were still operational. These findings are consistent with the cognitive demands of DFM and carry important messages for how those demands should be supported. Results suggest that rather than automating even more of the human role in fault management to minimize error counts, attention must be paid to the kinds of referents and representations that are most useful in informing the operator of what is going on in the underlying process and how best to cope with it.
