Why do fighter jets pilots use an oxygen mask? I always wondered why fighter pilots need to fly with a facemask.
Since the cabin in pressurised wouldn't the oxygen level be the same as in any commercial jet so sufficient for the pilot to remain conscious and aware?
Thank you
the pressurization system in a fighter plane might be able to furnish 10,000 ft cabin altitude at 30,000 feet, but the pilot would need supplemental oxygen when flying higher than that. In addition, if the cabin is breached above 30,000 ft the pilot would have very little time to get his or her mask on before blacking out, so the mask is worn at all times.
