No person may attempt to act as a crew member of a civil aircraft with what minimum alcohol content in the blood?

0.02 percent by weight or more
0.04 percent by weight or more
0.08 percent by weight or more
0.10 percent by weight or more

The correct answer is: 0.04 percent by weight or more

The minimum blood alcohol content (BAC) for a person acting as a crew member of a civil aircraft is set at 0.04 percent by weight. This regulation is in place to ensure safety in aviation, as alcohol can significantly impair a person's ability to operate an aircraft effectively. A BAC of 0.04 percent can adversely affect cognitive functions, coordination, and judgment, which are critical skills needed for flying. The regulation is more stringent compared to the legal limits for operating a motor vehicle in many places, reflecting the higher stakes involved in aviation. This limit applies to all crew members, regardless of their specific duties, highlighting the emphasis on maintaining safety in the aviation environment. Thus, any measurable alcohol content above this established threshold is prohibited for flight operations.
