From a physiological standpoint, how does alcohol affect a person who intends to operate an aircraft?
- A.Even small amounts can impair judgment, coordination, and vision before the person feels intoxicated
- B.It only affects performance after the person feels clearly drunk
- C.It improves night vision while slightly slowing reactions
Correct answer
A. Even small amounts can impair judgment, coordination, and vision before the person feels intoxicated
Why
Alcohol degrades the brain and eyes earlier and more subtly than most people expect. Feeling fine is not a reliable measure, because judgment about one's own impairment is itself impaired.
