Costs, in terms of direct implementation and oversight costs as well as the indirect costs related to disruption of air commerce and freedom of movement, are likely to be important considerations in assessing the utility and feasibility of implementing specific options to enhance GA security. For example, implementing broadly applied security requirements for all GA airports may impose significant cost challenges, particularly to small, rural airports where the need for such measures may be questionable. Also, airspace restrictions tend to be highly contentious because while they directly impact air commerce and the freedom of movement, they are viewed by some experts as being of questionable value in preventing a terrorist attack unless coupled with elaborate air defense capabilities. Deploying air defense capabilities on a large scale to protect against possible aircraft attacks carries a relatively high cost and involves extensive commitments of resources and collaboration between the FAA, the DHS and the Department of Defense (DoD). The costs and benefits associated with various mitigation options can be analyzed in a risk analysis framework – examining the threat and vulnerability of specific sectors of the GA industry – to better understand the tradeoffs between various options. Because of the diversity of GA airports, aircraft, and flight operations, and the varied threats and vulnerabilities posed by different sectors of the GA industry, a logical starting point in mitigating security risk would be to perform systematic risk analyses or security risk assessments examining specific components of GA. The FY2006 Department of Homeland Security Appropriations Act (P.L. 109-90) contains a provision requiring the DHS to examine the vulnerability of high-risk areas and facilities to possible attack from GA aircraft. This mandate focuses on the specific vulnerability of critical infrastructure to attack, which relates more closely to the threat to critical infrastructure and other significant sites posed by GA aircraft as discussed in this report. In this report vulnerability has referred instead to the specific weaknesses in security measures to protect GA airports and aircraft that could be exploited to gain unauthorized access to facilities and aircraft. A comprehensive risk assessment and risk mitigation strategy would likely take into account both the threat and vulnerability associated with GA operations as well as the potential cost of consequences associated with possible terrorist attack scenarios. 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(24) |
