Aircraft automation: the problem of the pilot interface.
Aircraft operations, particularly in the IFR environment, are rapidly becoming very complex. Studies have shown that this complexity can frequently lead to accidents and incidents. Results of studies performed at NASA and elsewhere are presented to show that one of the major themes evident in both the accidents and incidents and in the research performed to solve the problems associated with them is that of human error. Examples of various incidents and blunders, recorded in several studies, illustrate and emphasize the hypothesis: "As systems become more and more automated and complex, the more they become prone to human error. The problem can be eliminated or reduced only if good human factor principles are incorporated in the implementation of the systems, to guarantee a good man/machine interface". Aircraft systems technology, however, (e.g.: electronics, avionics, automation) is evolving and developing at a very high rate. Examples of research are presented showing where this emerging technology has been employed to reduce the complexity and enhance the safety and utility of the aircraft operations.
