What are general considerations regarding alcohol and flight duty?

• A. Alcohol impairs judgment and reaction time and causes dehydration; avoid drinking well before flight duty
• B. Alcohol enhances alertness and performance
• C. Alcohol has no effect on dehydration
• D. Alcohol is only a concern after completing flight duties

Answer: (A)

Alcohol directly impairs your ability to fly by slowing judgment, reducing reaction time, and weakening coordination, all of which are essential for safe flight operations. It also promotes dehydration, a common risk in aviation that can lead to fatigue, headaches, and dizziness—factors that further degrade performance in the cockpit. Because of these effects, the safest approach is to avoid drinking well before flight duty and ensure you’re well hydrated and rested before you fly.

These other statements don’t fit: alcohol does not enhance alertness or performance, and it does affect dehydration, so that claim isn’t correct. Also, alcohol is a concern before and during flight duties, not only after completing them.
