So the passengers can breathe.

You see, above a certain altitude, the air is so thin that it will not support human life.

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 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 do air liners have pressurized cabins?
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.
Does the b-29 Fifi have a pressurized cabin?
It did have a pressurised cabin originally.
How high do non-commercial airplanes fly?
The majority are limited to 10,000 or 12,000 feet (the height where you must use oxygen and/or a pressurized cabin). That's not a law, and some people own aircraft that operate on the same rules as commercial airliners.
Why cabin altitude is not equal to actual altitude?
Because the cabin inside the plane is pressurized?
When was the first pressurized cabin invented?
during the 1940's
What is the cabin pressure in a aircraft during ceiling altitude of flight?
Air craft cabin is fully pressurized.
Why the aircraft is pressurised?
At 35,000 feet, a human would suffer severe oxygen starvation without a pressurized cabin. Also known as "death". A pressurized cabin in a commercial - or military - airliner is essential at high altitude.
What is a flight perser?
On modern airliners, the Cabin Manager (chief flight attendant) is often called the purser.
Is packing soda on an airplane possible?
yes, the cabin and cargo holds are pressurized.
Why do we get air pressure when going up on an airplane?
Nearly all airliners, small jets, and even some small piston engine single and twin-engine airplanes are designed with pressurized cabins. Pressurizing the cabin allows the aircraft to operate at altitudes where there is too little air pressure for pilots and passengers to remain alert. In jets, clean air from the compressor stage of the engine, called bleed air, is routed via pressurized ducting into the cabin and an outflow valve regulates the escaping air to keep higher atmospheric pressure inside the cabin. During manufacture, rivet holes and window gaps are sealed, and inflatable door seals are installed, to reduce the amount of air that can escape, keeping the cabin pressurized. If the outflow valve fails, a pressure relief valve is installed to prevent the system from exceeding pressure design limits and rupturing the fuselage or blowing out a window. On piston engine airplanes, pressurized air from an engine driven turbocharger or supercharger pressurizes the cabin in the same manner.
