Frequent flyers may even recall the full discourse on the need to wear an oxygen mask. You may have questioned how a drop-down mask works because you haven’t used one in flight very often. It takes roughly 15 minutes for the drop-down oxygen mask to function.

If you take deep breaths, these 15 minutes of oxygen will be enough for you. The pilot is able to descend to an altitude where he can equalize the cabin pressure while you are inhaling the oxygen from the mask. Kindly #Like #Share #Comment Please We Need That From You!
