Is there an 'acceptable level' of intoxication?

Is there an 'acceptable level' of intoxication?

• A. Yes
• B. No
• C. Depends on flight duration
• D. Only for crew

Answer: (B)

Intoxication is not allowed in aviation because being under the influence can impair judgment, reaction time, and coordination, which are critical for safe flying. There is no safe threshold where impairment is acceptable for someone who may be flying or on duty; you must be fit for duty and free from impairment before operating aircraft. The idea that there might be an acceptable level, or that duration of the flight changes the rule, contradicts the safety-first standard that governs crew performance. The notion that it would be acceptable only for crew is also incorrect, since crew members must be unimpaired to perform their duties safely.
