... SECURITY ENHANCEMENT A good measure of the improvement from implementation of new security measures is a reduction in the number of simulated explosives brought onboard aircraft compared to the number brought onboard under a previous (or baseline)

... Although the capability of the operator to identify bombs on the EDS display is not part of the current certification process, it is one of the most important aspects of reducing false alarms and false negatives. According to current certification standards, a future system with a lower spatial resolution (i.e., less capacity to resolve individual objects)

... At JFK Term~nal One, a TPF system has recently begun operations serving European air carders. The threat vectors addressed in the two aviation security systems are shown in Figure 10-2.

... In the notional example in Box 10-1, 46 out of 100 passenger bags that contain MBTSs would be missed by the baseline DF security system. Five of the 46 bags were missed by CAPS (i.e., five simulated terrorists were not identified as selectees)

... The FAA should develop procedures and test capabilities to assess the operational performance of trace explosives-detection devices in an airport environment. Security Enhancement Factor The SEF described in this report is based on minimizing false negatives for the TAAS as a whole.
