Implementation of fatigue prediction models, such as the Sleep, Activity, Fatigue, and Task Effectiveness model, optimize scheduling by being able to predict pilot fatigue at any point in time. Although the mathematical model is limited by individual pilot differences it is the most accurate existing prediction because it takes into account ...
AIA Flight 808 was the first aviation accident where pilot fatigue was cited as a probable cause. [4] The NTSB issued a recommendation to the Federal Aviation Administration to review and update regulations on crew scheduling and duty time limits to incorporate the latest research into the effects of fatigue.

A sleep deficit accumulates with successive sleep-deprived days, and additional fatigue may be caused by breaking daily sleep into two shorter periods in place of a single unbroken period of sleep. A sleep deficit is not instantly reduced by one night's sleep; it may take two or three conventional sleep cycles for an individual to return to ...
The list of aircraft accidents and incidents caused by structural failures summarizes notable accidents and incidents such as the 1933 United Airlines Chesterton Crash due to a bombing and a 1964 B-52 test that landed after the vertical stabilizer broke off. Loss of structural integrity during flight can be caused by:
The same type of pilot errors and violations of standard operating procedure had been found in other accidents in which fatigue was not a factor. [3]: 171–173 To state that fatigue was a contributing factor, and thus part of the probable cause, would be inconsistent with the above finding and would, therefore, disrupt this flow of logic.
The report concluded that "the probable causes of the accident were the flight crew's mismanagement of the aircraft's speed, altitude, headings, and attitude through inconsistent flight control inputs resulting in a loss of control and their failure to abide by CRM (Crew Resource Management) principles of mutual support and calling deviations". [9]
The accident was the first to eventually precipitate the sterile cockpit rule. January 30, 1974 96 5 5 Pan Am Flight 806: Pago Pago: American Samoa: Boeing 707-321B: The aircraft encountered windshear caused by a microburst during approach and failed to recognize in a timely manner and correct the ensuing excessive descent rate. January 6, 1974 ...
Operating in aviation environments brings a combination of stressors that vary in nature and intensity. In the aviation industry, the main environmental stressors are time pressure, workload and overload, fatigue, noise, and temperature. [4] These stressors are interconnected, meaning that the presence of one may cause others to occur.
