Abstract : Since the earliest days of aviation, there have been aircraft accidents (now referred to as flight mishaps ). In earlier times, mechanical malfunctions were blamed for the greater number of mishaps. Engineering and technological advances, however, have since lowered the likelihood of machine-induced mishaps. Now, the man part of the equation (in a chain of events leading to a mishap) is far more likely to be the primary cause. (17:1) Thus, as aircraft are made more durable, reliable, and better able to sustain increased workloads, the humans who operate them must find ways to adapt or cope with the greater demands which result from improved machine capability. The bottom line question for today surfaces as: What causes crewmembers to commit errors in judgment, performance, or perception, and how might the influences of such causes be reduced? Progress in the field of Human Factors (HF) analysis has revealed some solutions while advancing the fundamental goal of flight safety--mishap prevention. This paper is intended to clarify and summarize the impact of HF studies on mishap prevention and show how aircrew fatigue is a common denominator among HF elements. Accepted techniques for combating and coping with fatigue are listed. Finally, recommendations on how to maintain operational awareness of aircrew fatigue considerations are proposed.
