Definition
A defense mechanism in which a person reacts to stress or anxiety by acting suddenly and without thinking through the consequences, often as a way to avoid dealing with the underlying problem.
Plain English
Acting on the first urge that comes to mind, instead of stopping to think it through.
Context Anchor
Seen in human behavior discussions about how students respond during training, especially when they rush an answer, a checklist step, or an in-flight decision.
Derivation
From the Latin 'impulsus,' meaning 'a push' or 'driven onward.' The word captures the idea of being pushed into action by an inner urge rather than by reasoned thought — useful in aviation, where snap reactions can override training.
Why Pilots Care
Impulsive actions can cause a pilot to skip checklists, ignore weather, or make rushed landing decisions that increase accident risk.
Intuition Check
Impulsive does not simply mean energetic, bold, or confident. It means acting too quickly for the amount of thought the situation needs.
Example Sentence 1
The instructor noted that the student became impulsive whenever the workload increased, reaching for switches before identifying the actual problem.
Example Sentence 2
An instructor notes impulsive tendencies when a student repeatedly starts maneuvers without completing the pre-maneuver checklist.
