This study deals with a simulation tool which enables evaluation of cockpit procedures by activating a crew behavioral model and dynamic environment of aircraft operations. This crew behavioral model employs both physical and cognitive characteristics of human crew members and the tool presents the sequence of their behavior in a form of three dimensional animation. In order to expand the area of application of this tool toward more specific design issues, functions of behavior in non-normal situations were developed. Applicability of this reinforced simulation tool was demonstrated by applying it to examinations of procedures of a research aircraft and identification of test cases of piloted flight simulation. The results of the behavioral simulation were compared with the results of piloted flight simulation.
