Pilot's complacency and confidence have been implicated as a contributing factors in numerous aviation accidents and incidents. It is related to ones belief that one is capable of performing in a certain manner to attain certain goals which is called 'Self-Efficacy' as a psychological concept. The purpose of this study was to construct and validate pilot's self-efficacy scale. This study examined the necessity of pilot efficacy in terms of pilot's confidence and complacency, and considered what is components and processes of pilot self-efficacy through the reference to literature. This Study newly defined 'pilot-efficacy' as vocational self-efficacy in flight operation field. Based on literature review and advisory group's review, there made 3 factors of Pilot-Efficacy:Flight-Efficacy, Relational/Communication Efficacy, and physical and psychological Stress-Coping Efficacy. Preliminary pilot-efficacy scale was administered to pilot group analysis Item analysis was conducted to select appropriate items and common factor analysis was done to identify the subcomponents of pilot efficacy scale. In result, 35 items were selected. The measurement of pilot efficacy for individual makes it possible to predict pilots' behavior when they make decision both normal and non-normal situation. This scale is expected to be not only predictable but also useful to enhance aviation safety. Finally, suggestion for following studies were discussed.
