Which statement best describes the 8-hour rule and crewmember duties?

• A. The rule prevents acting if alcohol consumed within last 8 hours
• B. The rule applies only to ground crew
• C. The rule is a guideline only
• D. The rule has no effect on flight

Answer: (A)

Alcohol affects judgment and coordination, so aviation rules require crewmembers not to act within eight hours of drinking. The eight-hour rule means you cannot perform crewmember duties if you have consumed alcohol within the last eight hours. This is a regulatory requirement, not a guideline, and it applies to all crewmembers—not just ground personnel. Because it governs whether you’re legally allowed to fly, it definitely has a direct effect on flight; if you’re within that eight-hour window, you must not act as a crewmember.
