The scale ranged from 1 meaning no fatigue to 7 being high. Participants had one month and a half to respond to the inquiry. Results on physical fatigue found that 93% of short/medium haul pilots scored higher than 4 on the FSS while 84% of long-haul pilots scored greater than 4. Mental fatigue found short/medium haul at 96% and long haul at 92%.
The NTSB found that there was a fatigue crack in the power control module and that it was not possible to visually inspect that type of failure. [1] The lower rudder control module's cast metal housing had broken. The end portion of the control module housing that housed the yaw damper actuator had separated from the main portion of the housing ...
Safety change process (SCP), which is part of LOSA, is a formal mechanism that airlines can use to identify active and latent threats to flight operations. [12] It is a guideline that communicates in detail what is an imminent threat to current operations or who is causing the threat.
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.
Five major sources of environmental stress affect pilots. In aviation, a source of stress that comes from the environment is known as an environmental stressor. [1] Stress is defined as a situation, variable, or circumstance that interrupts the normal functioning of an individual and, most of the time, causes a threat. [2]
In these incidents, there was a failure of control system components themselves (e.g. cables, hydraulics, flaps, slats, ailerons, rudder, stabilizer, trim tabs, auto-pilot). (Control system fatigue failures are here, but improperly installed or incorrectly adjusted controls in the next section.) United Airlines Flight 585, Boeing 737, March 3 ...

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.
