The air in an aircraft needs to be pressurised so that the people within the cabin don't pass-out from oxygen starvation at higher altitudes. The atmosphere can be described as a load of blankets wrapped around the world, the bottom layer has all the weight from above and is squashed, but as you go further up, there is less pressure on the blankets. this is the same with air... at sea level there is plenty of oxygen in the atmosphere to breathe, the higher you go the more sparse the air becomes and less oxygen is available for breathing. Aircraft are usually pressurised to the equivalent of 8,000ft as this is a safe threshold for breathable air.

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.
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!
What does it mean if air comes out of can when opened?
that the can contained pressurized air.
Why do you not experience a drop in air pressure when you travel via airplanes even though airplanes travel at high altitudes?
It is because an aeroplane's cabin is pressurized, meaning that it is sealed off from the atmosphere. This prevents air escaping and keeps the pressure constant.
What would happen to a passenger if airplanes are not pressurized?
They would suffocate.
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.
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.
What are the objects name that fly in the air?
airplanes aircrafts? what do you mean?
Why do airplanes have pressurized Cabains?
Because the air pressure drops the higher you go. If the cabin wasn't pressurised to ground level - all the passengers (and crew) would eventually suffocate !
What does aero nautical mean?
"Aeronautical" means "of or pertaining to air travel or airplanes" - for example, aeronautical design is the design of airplanes.
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!
What do you mean by air hoisters?
The correct term for an air hoister is just air hoist. An air hoist is a pneumatic hoist, which means it is operated by pressurized air or gas.
