dealing with operator ergonomics, selection, training, and motivation. Techniques for measuring operator performance are critical to the success of a program for assessing prototype systems, validating operator selection methods, evaluating new training techniques, monitoring and analyzing the on-line effectiveness of security-screening systems and personnel, and providing feedback to individual operators.

The allocation of functions between machine and operator is likely to have a significant influence on the effectiveness of future systems. In an apparent paradox, as screening systems become more automated, operator performance is likely to become even more important to the successful implementation of these systems. Operators will be performing more difficult and complex tasks that defy automation, and increased automation will introduce a host of new human performance issues. In developing new screening technologies, it would be more practical to integrate the proper allocation of functions into the technology development cycle itself, rather than to address the integration of the human operator into the system after the equipment has been designed and tested.

To aid air carriers and screening companies in selecting, training, and motivating passenger screening personnel and to provide direction on the use of ergonomics in designing security-screening equipment, the panel recommends that the FAA accelerate its program in human factors. The program can assist in developing effective measurements of operator performance, determining the optimal allocation of functions in new systems during development, and integrating research on operator ergonomics, selection, training, and motivation into the explosives-detection program. Successful implementation of any passenger screening system, based on current technologies or on a proposed new technology, requires the effective integration of human operators into the overall security system.
