What BAC level is specified for the FAA?

• A. 0.04
• B. 0.4
• C. 4.0
• D. 40.0

Answer: (C)

The key idea is safety: pilots must not operate an aircraft if alcohol has noticeably impaired them. The FAA sets a strict limit at 0.04 percent BAC, meaning no crewmember should be acting with 0.04 grams of alcohol per 100 milliliters of blood (0.04% by weight). This threshold is chosen to prevent impairment while still allowing for practical safety margins. The other numbers represent much higher levels of intoxication and would not be the regulatory limit, as they indicate severe impairment or worse. So the correct BAC level is 0.04 percent.
