Why don't airline pilots wear beards?

The habit of pilots not to wear beards responds to a request from the airlines, which in turn is dictated by safety reasons.

Why don't pilots wear beards? The answer seems to be related to security. Many airlines, including American Airlines, require pilots to be clean-shaven before going on duty. This is not an aesthetic whim, but a precaution based on studies dating back to 1987.

A 1987 study showed that beards can compromise the effectiveness of oxygen masks by increasing air leaks and reducing the supply of oxygen to the lungs. In emergency situations, such as in-flight decompression, this can lead to hypoxia and loss of consciousness, endangering flight safety.

The problem in theory is not only about pilots, but also passengers with beards. Beards can reduce oxygen supply in an emergency. Although there is no specific regulation banning beards for pilots, many airlines have adopted internal policies to ensure maximum safety on board./ CNA
