Understanding pilot response to flight safety events using categorisation theory

Categorisation theory explains our ability to recognise events in terms of a similarity overlap between either a prototypical, ideal case or a stored exemplar derived from experience. Evidence from aviation accident reports indicate that pilots are not always able to recognise flight safety events in real-time and this can lead to undesirable pilot behaviour. Flight safety events may not always arise in recognisable formats, especially as rare and unusual cue combinations are possible. Correspondence with prototypes or exemplars may be weak, creating borderline cases and harming recognition. In this article we extend categorisation theory to develop a new framework which characterises flight safety events. We model three case studies using the new framework to demonstrate how categorisation theory can be used to understand flight safety events of different types. Finally, we propose a roadmap for future research and discuss how categorisation theory could be applied to training or the organisation of flight crew reference material to improve response to inflight events
