While light GA aircraft appear to pose a relatively limited threat by themselves in terms of physically damaging critical infrastructure, larger GA aircraft pose a potentially more formidable threat. Due to the size and speed of some of these aircraft, particularly mid-sized and large business jets, they could inflict significant damage on buildings and critical infrastructure if used in a suicide attack. These aircraft have significantly larger payload and fuel capacities which would have a direct bearing on the degree of physical damage they could cause to buildings and infrastructure. Thus, in terms of both assessing risk and identifying options for mitigating the security risk posed by GA, the distinction between small GA aircraft that make up the large majority of the fleet and larger business jets has important implications. While small aircraft appear to pose a greater threat as possible platforms for chemical or biological attacks, large business jets appear to pose more of a threat from being exploited in a suicide attack scenario similar to the September 11, 2001, attacks using commercial airliners. Because the various sectors of GA appear to pose distinct threats, risk mitigation strategies arguably should be tailored to some degree to address the specific security threats posed by different sectors of 45 Gary Stoller. “Nuclear Plants near Airports May Be at Risk.” USA Today, June 10, 2003. 46 Robert M. Jefferson. Nuclear Safety: General Aviation Is Not a Threat (May 16, 2002), p. 4 and p. 1. Available from Aircraft Owners and Pilots Association, Frederick, MD. 47 Ibid, p. 1. the GA industry as well as the specific nature of potential security vulnerabilities that also vary across different types of aircraft and flight operations. Possible Options to Mitigate the Security Risks of A variety of options exist for mitigating security risks posed by GA aircraft and flight operations, many of which have been implemented or are currently under development or consideration. As previously discussed, the selection of mitigation options may need to be tailored to specific vulnerabilities and threats of different sectors of the GA industry which may differ significantly in their degree and scope. While a wide range of options are available, many of the more extensive and costly options for providing security may not be economically feasible, practical, or necessary at smaller GA airports away from major population centers. Several available options center on traditional security techniques to improve access controls and surveillance around GA facilities and better protect aircraft against theft and unauthorized use. Additional options include procedures for vetting individuals with authorized access to aircraft and aviation facilities, and procedures for clearing passengers. Another possible option for enhancing GA security would be to address law enforcement and homeland security response to suspicious activities and improved intelligence tracking of such incidents to identify patterns indicative of possible terrorist activity. Finally, in terms of adopting a layered security system to augment measures put in place at airports, airspace restrictions and defenses may be considered to protect high-profile sites and critical infrastructure from the threat of aerial attacks. 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(23) |
