The study, conducted by researchers at the Jenin Air University University and published in the Journal of Air Medicine and Human Performance, did not find any difference in oxygen saturation levels between clean analysts and those who have a short or long vehicle when they use standard oxygen masks.
In April, the researchers concluded “using the current airline oxygen mask upon request, oxygen saturation levels have never been hacked by any of the beard conditions.” “These results support the claim that pilots with a beard airline of any length will not be weakened by a lack of oxygen or smoke while dealing with the state of emergency while flying.”
The study included 24 volunteers that were tested in the ACR room that simulates conditions at a height of 30,000 feet. Participants wore oxygen masks in three beard conditions: clean haircuts, short meat below about 0.4 inches, and long beard more than 0.4 inches. The oxygen levels in the blood were continuously monitored, and the researchers did not find any major differences between the groups.
In addition, when exposed to a permeable smell salts with masks, none of the participants was able to detect the smell, regardless of facial hair. This indicates that beards do not interfere with the mask’s ability to prevent smoke or other irritants.
These results are in line with A study of 2018 commissioned by Air CanadaThis prompted the airline to change its policy and allow pilots to obtain a beard. This research, conducted at Simon Fraser University, was likely that the length of the beard had no effect on the effectiveness of experimental oxygen masks.
Many major American airlines still prevent pilots from having a beard, pointing to safety concerns about the oxygen mask seals. Transport companies such as America, DeTa, UNITED, Southwest, Jetblue and Spirit require that the pilots be a clean haircut, while others such as Hawaii, Avello and Alegeant allow facial hair.
FAA does not explain that the pilots are clean. This base is usually assigned by the carrier itself.
