Faulty pilot judgment has been identified as a contributing cause in a majority of aircraft accidents attributed to pilot error (Jensen, 1981; Diehl, 1991; Orasanu, 1993). Furthermore, given that such errors often occur in bad weather following instrument or system failure and in time-pressured circumstances, it is reasonable to assume that the resulting stress from these anxiety-provoking situations may exert an important degrading influence on the quality of decision making. Indeed, there is an ample abundance of anecdotal reports and post-hoc accident and failure analyses that attributes faulty decision making, in part, to the degrading influence of stress (e.g., Connolly, Blackwell, & Lester, 1987; Lubner & Lester, 1987; Simmel, Cerkovnik, & McCarthy, 1987; Simmel & Shelton, 1987).
