What is the BAC level for United Airlines?

• A. 1.0
• B. 2.0
• C. 0.2
• D. 20.0

Answer: (B)

In aviation safety, there is a strict limit on blood alcohol concentration for crew members. BAC is the percentage of alcohol in the blood, and for flight operations the standard limit is 0.04% (0.04 grams of alcohol per 100 milliliters of blood). This low threshold is enforced because even small amounts of alcohol can impair judgment, coordination, and decision-making during a flight. United Airlines and other carriers generally follow this policy, often requiring zero tolerance before duty or imposing a mandatory no-drink period prior to reporting for duty. The numbers listed in the question do not reflect this commonly cited limit, since 0.04% is the relevant benchmark, far below values like 0.2%, 1.0%, or higher. The key idea is that the safe-operating BAC for aviation is 0.04% or lower, not any of the higher figures presented.
