A possible solution to overcome some of these limitations involves the implementation of behavioral pattern recognition techniques. As described in a recent commentary on GA security, behavioral pattern recognition was highlighted as being “...designed to maximize detection while minimizing, if not eliminating, issues of civil liberties.”58 Behavioral pattern recognition – which is in use at airports worldwide and has been highlighted in numerous profiles of Israel’s El Al airlines’ pre-boarding security screening – examines deviations from normative behavioral patterns. It has been suggested that behavioral pattern recognition could be applied in the GA environment by providing specific training to maintenance and line workers, for example, making them an integral part of an airport’s security network rather than having a small number of employees responsible for security.59 One challenge in behavioral pattern recognition is that single events may not stand out, but aggregate samples of slightly unusual activity may provide tell-tale signs of preparations for launching a terrorist attack. However, assimilating and correctly interpreting this data remains a significant challenge. For this reason, a “reporting tree”60 is recommended for guiding decisions about responding to suspicious behavioral patterns. The “reporting tree” concept is integrated into the TSA’s security training for flight schools, which is a required security training element for flight school employees under Title 49, Code of Federal Regulations, §1552.21 et seq., but has not yet been expanded to other aspects of GA security. A reporting tree might include notifying a supervisor, such as a chief flight instructor or flight school manager, about strange inquires or behaviors by a student pilot, and escalating this information up the reporting tree to law enforcement or federal 58 Robert Olislagers. “General Aviation Security.”, p. 61. 中国通航网 www.ga.cn 通航翻译 www.aviation.cn 本文链接地址：Securing General Aviation 通用航空安保(33) |
