Definition
A state of impaired physical and mental function caused by alcohol or other drugs in the body, affecting judgment, coordination, reaction time, vision, and decision-making. In aviation, intoxication includes any level of impairment from alcohol or drugs that degrades a pilot's ability to safely operate an aircraft, even when blood alcohol concentration is below legal driving limits.
Plain English
Being affected by alcohol or drugs to a point where your body and mind no longer work properly. Even a small amount can be enough to make flying unsafe.
Context Anchor
Seen in aeromedical, alcohol, preflight fitness, and personal minimums discussions.
Derivation
From the Latin 'toxicum' meaning 'poison.' Literally 'in a poisoned state.' The word reminds us that alcohol and drugs act as toxins on the body — a useful framing for pilots, because the effects on the brain and senses are real physiological impairment, not just 'feeling tipsy.'
Why Pilots Care
Flying while intoxicated is illegal under FAA regulations and one of the leading causes of fatal accidents.
Grounding Statement
A pilot may feel relaxed and normal after drinking, but still have slower reactions and weaker judgment than safe flying requires.
Intuition Check
Intoxication does not always mean stumbling, slurred speech, or feeling drunk. In aviation, it means alcohol or another substance has reduced the ability to fly safely.
Example Sentence 1
The pilot cancelled the morning flight after realizing the previous evening's drinks could still leave him in a state of intoxication.
Example Sentence 2
Regulations require waiting at least eight hours after drinking to ensure any effects of intoxication have passed.
