What is the purpose of the blood alcohol concentration limit for pilots?

The purpose of the blood alcohol concentration limit for pilots is primarily to ensure the safety and integrity of flight operations. This regulation is designed to minimize the risk of accidents that can arise from impaired judgment, decreased coordination, and other negative effects of alcohol on a pilot's ability to operate an aircraft safely. By establishing a clear and enforceable limit, aviation authorities aim to uphold high safety standards within the aviation industry, protecting both pilots and passengers as well as the general public.

While improving pilot performance, compliance with international regulations, and facilitating better communication with air traffic control (ATC) are relevant factors in aviation operations, they are not the primary focus of the blood alcohol concentration limit. The critical aspect centers on maintaining a consistent level of safety and preventing incidents linked to alcohol consumption in flight.
