Because the air at that altitude is too thin so you're not able to breathe it

Why do you have oxygen masks on airplanes?

On airliners its because you're flying at very high altitudes which means there is very little oxygen and if one of the windows are broken that air will come so if you don't have the oxygen masks you'll die from lack of oxygen in case of an emergency like there is a gas leak, or there are toxic fumes released into the air, or if the plane is about to crash and people start to panic


Can you bring face masks on a plane?

Yes, you can bring face masks on a plane. It is recommended to wear them during the flight for added protection against germs and viruses.


Can you take face masks on a plane?

Can I bring face masks on a plane and are there any specific guidelines or restrictions regarding their transportation"?

Yes, you can bring face masks on a plane. However, there are specific guidelines and restrictions regarding their transportation. It is recommended to check with the airline for their specific rules on carrying face masks.


Can you bring sheet masks on a plane?

Yes, you can bring sheet masks on a plane in your carry-on luggage. Just make sure they comply with the TSA's liquid restrictions and pack them in a clear, resealable plastic bag.


Do face masks count as liquid when packing for a plane trip?

No, face masks do not count as liquid when packing for a plane trip. They are considered personal items and can be carried in your carry-on bag without any restrictions.


How does sudden decompression cause a plane to crash?

It doesn't--this is just an urban legend. Pressurized airplanes can usually maintain cabin pressure with one or more windows completely missing, but even if they lost all cabin pressure, the pilots would use oxygen masks and the emergency masks would drop in front of the passengers. Then the airplane would descend to under 10,000 feet where you wouldn't need oxygen.


Why are air plane cabins pressurized?

Outside the plane is way less pressure and less air to breath. If inside the plane was the same pressure as the outside, people might die depending on how high the plane is. ***************************************************************************** FAA law mandates an un-pressurized aircraft the pilot and co-pilot must wear oxygen masks at or above 12,000 feet ASL altitude. Hypoxia sets in with no warning and no symptoms.


What is the oxygen level of the air expected to be when flying in a pressurized cabin of a plane?

The percentage of Oxygen in the air is the same in airplane as it is outside the airplane. The only difference is the pressure levels. If the pressure drops too much then the total amount of Oxygen will be insufficient for you to breath and you will pass out. The airplane only carries oxygen for use in emergency and is dispensed in the oxygen masks of the crew and passengers. Maybe your Question is asking what the total volume of oxygen is available in a pressurized airplane. I don't know that.


Where does oxygen on airplanes come from?

Normal oxygen found on airplanes in the cabin is just air from the ground that is pressurized. However, air coming from emergency masks is from a storage tank or oxygen generator in the cargo hold or above the seats. WRONG: Airplane air is compressed from the outside air by the engines and then cooled down though air-conditioning and filtered. Humidity is then added. The air leaves the plane through ports to keep optimal pressurization (these ports can open and close as necessary). In an emergency, air is created by a chemical oxygen generator, most commonly sodium chlorate, which gives off oxygen when heated. When you don't know something, don't respond; rather than filling in BS information.


What grades are coordinate plane worksheets needed for?

Coordinate plane worksheets are needed for fourth grade and up because fourth grade is when you learn basic graphing and that is when you would need a coordinate plane worksheet.
