Modern airliners fly at altitudes in excess of 30,000 feet. At such heights the air is very thin and humans cannot get enough oxygen. Prolonged exposure to such conditions can be fatal. A pressurized cabin, though, has air pressure and oxygen levels that are habitable and does not but people at any risk.

Why are airplane cabins pressurized?
Airplane cabins are pressurized because humans cannot breath at a very high elevation.Aircraft are pressurized to allow them to fly higher. Without pressurization, the amount of oxygen in the air would not be sufficient for humans to breathe.
How are air craft cabins pressurized?
Pressure is created in the engines and/or APU as "bleed air" and enters the cabin.
Why air crafts at high altitude must have pressurized cabins?
Mostly not enough oxygen in the air at the low pressure up there.
Why are submarines cabins pressurized?
To keep water from leaking in.
Why must airplane cabins be pressurized?
Because at altitudes above 10,000 feet there is not enough air for humans to breathe. Aircraft cabins are pressurised so that the internal pressure is equal to that at about 7,000 feet.
Why is an airplane cabin air pressurized?
At altitudes above 10,000 feet there is not enough air for humans to breathe. Aircraft cabins are pressurized so the pressure is equal to that at about 7,000 feet. Commercial airliners fly at altitudes up to 40,000 feet.
Why are aircraft cabins pressurized?
For two reasons: 1. To make the air breathable and comfortable. 2. In conjunction with the above, to keep the temperature at a safe level.
What was the breakthrough technology introduced by Boeing 307 stratoliner in 1940?
Pressurized Cabins
Does air pressure increase as you get farther away from the ground?
No it decreases. That's why plane cabins need to be pressurized during flights. As your elevation increases, the air pressure decreases. It's inversely proportional.
How are the cabins of jet planes pressurized?
An airplanes cabin is pressurized with what is called "bleed air", air that is siphoned out of the compressor chamber of the engines. The air is directed through duct work to the belly of the plane, where it is filtered, cooled, then circulated in the cabin. Equal amounts of air are siphoned off each of the engines. If one engine should fail, the other engine(s) provide the bleed air.
How are airplane cabins pressurized?
There are air pumps in the outer jacket of the jet engines. Outside fresh air is taken in, compressed by pistons, and forced into ducts that send it into the cabin. The cabin is tightly sealed with carefully calculated exhaust. This allows the small air pump to keep the cabin pressurized. The cabin heaters are usually part of the pressurization system.
Why must there be pressurized cabins in space crafts?
If it wasn't pressurised there would be no air and the astronauts would die. Of course they could keep their spacesuits on but that would not be comfortable for an extended period of time.
