What is the FAA BAC limit as stated?

• A. < .004
• B. < .02
• C. < .08
• D. < .01

Answer: (A)

Alcohol in the bloodstream slows reaction time, impairs judgment, and reduces coordination—unacceptable risks for operating an aircraft. The FAA sets a very strict limit for blood alcohol concentration for anyone directing or flying a plane: you must be under 0.04 percent BAC. This means 0.04 grams of alcohol per 100 milliliters of blood, and being at or above that level is not permitted while on duty. This threshold is intentionally low, especially compared to typical driving limits, to ensure pilots and crew can perform precisely and safely. In practice, many airlines require zero BAC when reporting for duty, and there’s often an eight-hour rule between drinking and flying. The values shown reflect very small fractions, but the official FAA limit is 0.04 percent, a standard not listed among them; the core idea is that the allowable BAC is extremely low. If you had to pick from these options based on safety, choosing the smallest value aligns with the safety-first approach, though it’s important to remember the actual FAA limit.
