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.

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.
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.
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.
Is it safe to travel by air with a hernia?
Yes, the plane is pressurized.
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.
How does a high altitude pilot overcome the lack of air pressure?
They could not remain conscious unless they either pressurized the cabin of the plane or wore a face mask that supplies them with pressurized air.
What was the breakthrough technology introduced by Boeing 307 stratoliner in 1940?
Pressurized Cabins
