At what altitude would flight crew have to wear oxygen continuously?
Use of Oxygen 605.32 (1) Where an aircraft is operated at cabin-pressure-altitudes above 10,000 feet ASL but not exceeding 13,000 feet ASL, each crew member shall wear an oxygen mask and use supplemental oxygen for any part of the flight at those altitudes that is more than 30 minutes in duration.
Why military aircraft pilots must wear masks that provide oxygen when they fly at high altitudes?
Fighter pilots wear masks to supply them with oxygen to avoid Hypoxia when flying over 10,000 feet. Fighter aircraft have a dynamic pressurization system & when flying at very high altitudes, the pilot will have decreased atmospheric oxygen pressure for breathing. Masks prevent this.
Why do aircraft travel at such high altitudes if oxygen levels at those altitudes are so dangerously low?
That lack of oxygen can occur at higher altitudes due to a decrease in oxygen pressure, according to the FAA. As the plane ascends, the level of oxygen decreases, which can cause rapid decompression for an aircraft that is not pressurized in the same way as a commercial airplane.
Which oxygen system is used at altitudes of 35000 to 40000 feet?
Above 25,000 feet, your re-breather mask can’t keep the oxygen percentage high enough to keep you safe. Aircraft that operate above 25,000 feet and up to 40,000 feet use a “diluter-demand” oxygen system.
What is the requirement for supplemental oxygen above 15000 MSL?
(ii) Above 15,000 feet MSL, oxygen to each occupant of the aircraft, other than the pilots, for one hour unless, at all times during flight above that altitude, the aircraft can safely descend to 15,000 feet MSL within four minutes, in which case only a 30-minute supply is required.
At what height can you not breathe?
An elevation of about 20,000 feet above sea level is the maximum height at which sufficient oxygen exists in the air to sustain us.
Do fighter pilots feel roller coasters?
The feel is somewhat similar, although it’s better when you are the pilot and you control the course. Going backwards on roller coasters has been hard since I started flying. A fighter pilot doesn’t normally execute a reverse loop at 4gs, so it feels weird to feel the g’s/lateral forces while going backwards.
When do pilots use oxygen at cabin altitudes?
And that at cabin altitudes above 14,000 feet pilots must use oxygen at all times. And that above 15,000 feet each occupant of the aircraft must be provided supplemental oxygen. All of this is spelled out in Federal Aviation Regulations Part 91.211.
Should you use portable oxygen when flying?
Most pilots don’t think too much about using portable oxygen. Sure, everyone knows that you have to use supplemental oxygen if you fly more than 30 minutes at cabin pressure altitudes of 12,500 feet or higher. And that at cabin altitudes above 14,000 feet pilots must use oxygen at all times.
How high can you fly without oxygen on a plane?
So a brief excursion upward to, say, 13,000 feet, with a return to below 12,000 feet within 15 minutes or so, is completely legal and does not require supplemental oxygen. But as soon as those 30 minutes are up, the required flight crew must be using supplemental oxygen.
How do airliners provide sufficient oxygen pressure for crew and passengers?
In airliners, providing sufficient oxygen pressure for crew and passengers is done by pressurizing the entire compartments occupied by humans, often to about 6,000 feet, where the is plenty of oxygen pressure for normal operations.
