A very logical but not at all predictable reason is hidden behind the pilots who should not have on them… a trace of hair, on the part of the face.
A reason that doesn’t cross your mind is behind the shaved faces of not only them pilots but also of all the men who work in air flights.
Specifically, the pilots as we very often observe is shaved and indeed very well for one precise reason. Airline companies have communicated to their employees that they should not have any hair in their facial area since this interferes with the proper intake of oxygen when using the special mask.
As they point out, the beard is able to prevent it oxygen when it is used under the use of the mask, in moments where it will be needed, and in particular the pilots who have a much more difficult task in a complicated and -among other things critical- situation during the flight.
As the acquaintance explained YoutuberZack D.Films via his account: “When a pilot wears a mask oxygen in an emergency, it forms a tight seal around the face. This is vital to providing the right amount of oxygen.
But if a pilot had a beard, the facial hair would prevent the mask from sealing properly – causing an oxygen leak and possibly unfortunate consequences.”
