Airplanes need to be pressurized because the atmospheric pressure, at such a high altitude, acts upon your body. Your body is trying to adjust to maintain equal pressure, causing your ears pop. Because your body cannot maintain equal pressure by itself, the airplane makes up for the rest of the pressure that is needed to equalize the atmospheric pressure.

What would happen to a passenger if airplanes are not pressurized?
They would suffocate.
Is aircraft carying cargoes pressurized?
Generally yes. Few large commercial airplanes travel under 10,000 feet where you need oxygen or pressurization.
What altitude are commercial airplanes pressurized to?
The highest altitude is 8,000 ft. But depending on the aircraft, it is usually pressurized to around 6,500 to 7,000 ft.
When airplanes fly high in the atmosphere why must they be pressurized for the passenger's safety?
the cabin could explode or crack
Why must airplanes be pressurized?
At the high altitudes which airliners fly in, there is less dense. Since air is good for us humans, the cabin is pressurized in order to provide enough air to breathe.
What aircraft can fly in the thermosphere?
Jet or rocket powered, with a pressurized cabin.
Why are airplanes pressurized?
Most air planes are pressurized, because at high altitudes, the air pressure is less than humans can handle, which causes us to black out. Bad vacation when your pilot blacks out at 30,000 feet!
Why you suppose that airplane windows are smaller than bus windows?
Airplanes are often pressurized. A large window would be excessively difficult and expensive to make it strong enough to not blow out. So they use small windows on airplanes.
Why do airplanes need wings?
airplanes need wings so they can glide and land correctly
What happens to air pressure as you move from the Earth's surface?
Air pressure decreases as you move away from Earth's surface. The higher up you go, the thinner the air becomes. Thinner air means less density and/or less pressure. This is the reason passenger airplanes need to have "pressurized cabins". Fighter jet pilots also need to wear pressurized suits and have a supply of oxygen on-board. Hope this helps!
Why are aeroplane cabins pressurized?
Airplanes often fly at great altitudes, of 10 kilometers or more. People would have serious trouble breathing at that altitude.
Why do you need to breathe faster at the top of a tall mountain?
the air is thinner the higher up you go so it is harder to breathe. That's why there are pressurized cabins on airplanes because you wouldn't be able to breathe without the pressure keeping the air inside
