ABSTRACT
The recognition of the importance of human factors to system safety, especially in aviation, is constantly increasing. Foushee (1993), in his keynote address at the International Civil Aviation Organization Flight Safety and Human Factors Symposium, even talked about the human factors revolution, emphasizing how quickly human factors thinking has infiltrated the world of aviation and high technology in some parts of the world. Consequently, the Federal Aviation Administration (FAA), in its 1990 National Plan for Aviation Human Factors, amongst others placed stronger emphasis on human factors as part of the aircraft and avionics certification requirements (Foushee, 1993).
