What is the maximum flight altitude without oxygen?


What is the maximum flight altitude without oxygen? The flight crew must use supplemental oxygen for the entire duration of flight operations above a cabin pressure altitude of 14,000 feet MSL (14 CFR § 91.211).


What are the oxygen requirements for flight?

FAA encourages oxygen use for pilots on flights operating above 10,000 feet mean sea level (MSL). The regulations for flying above an altitude of 12,500 up to and including 14,000 are fairly simple. At that altitude, all crew must use supplemental oxygen continuously if the flight is over thirty minutes.


How high can you fly without oxygen?

For Part 91 General Aviation operations the required flight crew must use supplemental oxygen for any portion of the flight that exceeds 30 minutes above a cabin pressure altitude of 12,500 feet mean sea level (MSL) up to and including 14,000 feet (MSL).


What is the oxygen mask rule on a plane?

But, that speech carries a beautiful message regarding self-care. The Oxygen Mask Rule is simple: if the cabin loses pressure, oxygen masks will fall from above. You are to place yours on yourself before trying to help others.


Is it safe to fly with low oxygen levels?

Lower levels of oxygen in your blood may make you feel unwell or could even be harmful to you during or after your flight. This means that, even if you do not usually need oxygen, you may need it while flying. Additional oxygen keeps the oxygen levels in your blood at a comfortable level and keeps you safe.


At what altitude does hypoxia start?

In aeronautics, hypoxia typically results from a decompression or lack of pressurisation of the aircraft cabin. Hypoxia occurs within a few minutes if the cabin pressure altitude rises to between 5,000-6,000 m (about 16,000 - 20,000 ft).


Do airlines pump in oxygen?

Answer: No. The cabin is pressurized between 6,000 and 8,000 feet on long flights. Adding supplemental oxygen is not necessary, because the percentage of oxygen is the same as being on the ground at those altitudes.


What happens if a plane loses oxygen?

The primary problem is low oxygen, says Professor Frances Ashcroft, a physiologist at Oxford University. Low pressure would cause little more than discomfort in the ears and eyes, but the associated drop in oxygen levels makes people pass out if they do not put their oxygen masks on within about 15 seconds.
