University of South australia UniSA Background However, even with all these advances in aviation safety there remains a stubborn remnant of air crashes which are seemingly not eradicable Of these accidents worldwide. Helmreich and foushee have suggested that 70% are due to flight crew actions or in some cases inactions. HUMAN ERROR This is despite the fact that pilots are extremely technically competent and well trained in crm There is no question that flight crews are highly trained to operate in the technical and human environments of the cockpit

University of south australia UniSA Background Why do such accidents happen and, perhaps more disturbingly, why do they continue to happen? Research has shown that most are due to a momentary loss of concentration or awareness during which the flight crew did not consciously notice that a necessary event did not occur, or that an adverse event did occur

University of South australia UniSA Background In order to function pilots build up a mental model of what is happening around them New information they receive will be perceived and restructured in terms of this model until an event happens which forces an unsettling recognition that the model is actually false. This is termed loss of situation awareness(SA) If this happens too late on in a critical process, the result can be an adverse event
