Abstract : This report describes the second year activities of a program of research and development to enhance pilot and aircrew emergency decision skills. Major objectives of the work carried out were to: extend theoretical models developed earlier, to carry out four experimental studies which would yield basic pilot judgment data for cognitive and situational factors involved in cue patterns typical of aircraft emergencies, to design a scenario generation system utilizing cognitive and situational factors, and to present a general approach for training and assessing aircrew emergency decision skills. The work of the second year of this program focused heavily on the specification of relationships of cues and cue patterns as decision process inputs in the complex, high performance aircraft setting. Meta-evaluation theory and principles of instructional system evaluation are examined in the context of decision training in order to identify theoretical and practical considerations for evaluating aircrew decision training. A prototype instructional approach is presented in the form of an emergency decision situation which embeds elements of a decision process model.
