Physiological stress is a physical change due to influence of fatigue, anxiety, hunger, or any factors that may change a pilot's biological rhythms. [16] Lastly, psychological factors include personal issues, including experiences, mental health, relationships and any other emotional issues a pilot may face. [ 16 ]
A Federal Aviation Administration (FAA) study of 55 human-factor aviation accidents from 1978 to 1999 concluded that number accidents increased proportionally to the amount of time the captain had been on duty. [7] The accident proportion relative to exposure proportion rose from 0.79 (1–3 hours on duty) to 5.62 ( more than 13 hours on duty).

The nation’s top accident investigator said Thursday that a surge in close calls between planes at U.S. airports this year is a "clear warning sign” that the aviation system is under stress.
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]
This situation is especially dangerous since 26% of pilots deny the effect of fatigue. The official statistics showed a percentage of 4% to 8% of aviation accidents related to fatigue. [27] However, since fatigue lowers the performance of pilots and cripples their decision making process, fatigue impacts a much larger percentage of aviation ...
Mental health in aviation is a major concern among airlines, regulators, and passengers. This topic gained more attention after the 2015 Germanwings crash, which was deliberately caused by the plane's copilot. Little data exists on mental health in aviation, but steps to gather relevant information and provide better solutions are underway.
The NTSB investigated the crash and determined that the accident was caused by a structural failure that occurred at the wing-to-fuselage attach point, with the right wing failing just before the left. The investigation disclosed "evidence of fatigue cracks in the right wing's lower surface skin panel, with origins beneath the forward doubler.
