Definition
Stressors are the events, conditions, or demands — physical, physiological, or psychological — that trigger a stress response in a person. In aviation, they include factors such as turbulence, heat, fatigue, time pressure, equipment malfunctions, workload, personal problems, and interpersonal conflict.
Plain English
Stressors are the things that cause stress. They are the triggers, not the reaction. Anything that puts pressure on a pilot — in the cockpit or in life — can be a stressor.
Context Anchor
Used in aviation human factors and instructor discussions about managing student performance, decision-making, and workload.
Derivation
From the English word 'stress' (originally meaning hardship or pressure, from Latin 'strictus' — drawn tight) plus the suffix '-or' meaning 'something that causes.' So a stressor is literally 'something that causes pressure.'
Why Pilots Care
Unmanaged stressors reduce attention, slow decision-making, and increase the chance of errors during flight.
Grounding Statement
A stressor can be as simple as poor sleep, time pressure, bad weather, or worry outside the cockpit adding pressure during a flight.
Intuition Check
Stressors are not the same as stress. A stressor is the cause or source of pressure; stress is the person’s reaction to that pressure.
Example Sentence 1
The instructor listed common stressors for student pilots, including checkride pressure, unfamiliar airspace, and time-limited solo flights.
Example Sentence 2
Financial worries or lack of sleep can act as stressors that reduce a student's ability to focus on the lesson.
