This is the first of four reports assessing the deployment of technologies (., equipment and procedures) by the Federal Aviation Administration (FAA). This assessment of the 1997–1998 deployment of technologies by the FAA to improve aviation security was conducted by the Panel on Assessment of Technologies Deployed to Improve Aviation Security under the auspices of the National Research Council (NRC) Committee on Commercial Aviation Security. This is the first part of a four-part assessment that will be completed in fiscal year 2001. The subsequent parts of this study will be continued by a new committee that will be convened by the NRC in 1999. The form of this report reflects the panel’s.
