What is the maximum permitted blood alcohol concentration (BAC) for crew members?

• A. 0.02
• B. 0.04
• C. 0.08
• D. 0.10

Answer: (B)

The maximum permitted blood alcohol concentration (BAC) for crew members is set at 0.04%. This limit is enforced by aviation authorities to ensure safety in flight operations, as alcohol can impair judgment, coordination, and reaction times. A BAC of 0.04% means that a pilot can have a very low amount of alcohol in their system while still functioning within the legal requirements to operate an aircraft. Maintaining this standard helps reduce the risks associated with flying under the influence, as even small amounts of alcohol can negatively affect performance. Other options present higher BAC levels, which do not comply with aviation regulations designed to promote safety for both crew and passengers in the aviation environment.
