What is the BAC limit for reporting to duty?

• A. .02 BAC
• B. .04 BAC
• C. .00 BAC
• D. .01 BAC

Answer: (A)

Before duty, crew members must be free of impairment from alcohol. The limit used for reporting to duty is 0.02 percent BAC. That means if your BAC is 0.02% or higher, you’re not permitted to report for duty. This conservative threshold helps ensure you’re fully capable of handling the duties and making sound judgments right from the start of the shift.

It’s also useful to contrast this with the in-flight limit: once on duty and flying, the limit is higher—0.04% BAC. If your BAC reaches 0.04% or more while performing duties, you may not operate the aircraft. There’s also the general eight-hour rule after drinking to consider, which adds a safety margin before returning to duty. The other numbers don’t fit the reporting requirement because they don’t align with the official threshold set for reporting to duty.
