Pressurization is for the comfort of crew and passengers.
The planes fly higher to save on fuel. The less dense air higher up causes less drag. It is also unfortunately harder to breathe. Pressuriziation makes it easier to breathe without special equipment, like breathing apparatus or oxygen.

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.
How do planes generate thrust?
Planes generate thrust by using jet engines or propellers. Jet engines work by taking in air, compressing it, mixing it with fuel, and igniting it to produce a high-speed exhaust that propels the plane forward. Propellers create thrust by rapidly spinning and moving air backwards to create a forward force.
Which aeroplain travels faster than sound?
The Concorde was a commercial supersonic jet that traveled faster than the speed of sound. It had a top speed of around Mach 2, which is about 1,354 miles per hour.
How do planes create thrust?
Planes create thrust by using their jet engines, which take in air, compress it, mix it with fuel, ignite it, and then exhaust the hot gases out of the back of the engine at high speed. This action produces a reaction force in the opposite direction, pushing the aircraft forward.
Do all planes have the same speed?
No, different planes have different speeds based on their design and intended use. Commercial airliners typically fly around 500-600 miles per hour, while military jets can exceed speeds of 1,000 miles per hour. Additionally, smaller propeller planes generally have lower speeds compared to larger jet aircraft.
Why are submarines cabins pressurized?
To keep water from leaking in.
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.
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.
What was the breakthrough technology introduced by Boeing 307 stratoliner in 1940?
Pressurized Cabins
How do jet planes fly?
Jet planes fly with the help of Thrust and Lift produced by the jet engines.
What is the use of jet planes?
Jet planes can be of many types and some perform better than piston planes.
What contrabutions has World War 2 made to out modern society?
Today's jet passenger airliners have pressurized cabins for it's passengers; this was pioneered in the B-29 Superfortess's that flew bombing missions over Japan during WW2.
What are facts about jet plane?
Jet planes are faster than the normal propeller powered airplanes. Jet planes were invented by Sir. Frank Whittle. There are also supersonic Jet planes. Concorde was the fastest Passenger Jet plane.
What is a collective noun for jets?
All collective nouns are common nouns.There is no collective nouns specifically for jet planes, however the collective nouns for planes can be used; they are:a fleet of planes (a fleet of jet planes)a squadron of planes (a squadron of jet planes)a stack of planes (a stack of jet planes)
Why air-crafts at high altitude must have pressurized cabins?
There is not enough oxygen in the air at altitudes above about 17,000 feet. In addition, as you ascend, the temperature decreases. The temperature in which jet airliners fly often is minus 40 degrees or lower.
Are jet planes apart of airlines?
Yes, jet planes are that - planes, whereas airlines usually refers to a company that uses planes to ferry people around.
How are air craft cabins pressurized?
Pressure is created in the engines and/or APU as "bleed air" and enters the cabin.
