The terrorist-controlled surface-to-air fire (SAFIRE) threat places U.S. air-carrier pilots and passengers at significant risk. The problem addressed in this study is that air-carriers do not provide pilots with risk-reduction training designed to prepare them to deny, detect, defeat, and report SAFIRE attacks, and there is limited scholarly research to address this topic. The purpose of this quantitative, comparative study was to analyze U.S. air-carrier pilot SAFIRE risk-reduction training as related to the principles of adult learning theory that state adult learners will be more successful when they perceive training as valuable and applicable to their daily tasks and responsibilities. The analysis included descriptive statistics to determine the majority (70.5%) of 112 U.S. air-carrier pilots contained in the self-selected purposive sample perceived SAFIRE risk-reduction training as valuable. The analysis conducted using comparative statistics indicated there was not a statistically significant difference in the perception of the value of SAFIRE risk-reduction training between the four sample groups. The findings indicated the majority (85.7%) of air-carrier pilots believed an effective SAFIRE risk-reduction training program must consist of a combination of computer-based training, classroom training, and simulator training methods. Recommendations for future research are to determine if the results of this study apply to non-U.S. air-carrier pilots, identify parameters for specific countertactics, and generate specific objectives for potential training programs.
