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.

Why does a bottle get crumpled up while in an airplane?
it is air pressure
What defines low air pressure and where is low air pressure typically found?
There is low air pressure usually when you are up in a mountain or in an airplane like when your ears pop after you get in an airplane and you are at high altitude your ears do this because the pressure inside your ears and the pressure in the air is not the same. When there low air pressure the air is less dense.
What makes an airplane lift up into the air?
The air under the plane's wings exerts pressure.
If there is a bag of chips on airplane why does it puff up while in flight?
Air pressure.
What does glider work?
By glider do you mean like paper airplane?? it is held up by air pressure,,This will not work on the moon. There is no air there.
What are many have air pressure if one drum is going up and other drum is going down?
what are many have air pressure if the one drum is going up and other one is going down
Which states Benoulli's principle?
Bernoulli's principle says that the pressure exerted by a moving fluid (liquid or gas) decreases as it's speed increases. An example of this is how an airplane flies. The shape of the wing forces the air moving over the top of the wing to go farther (and thus faster) than the air going under the wing. The slower air going under the wing exerts more pressure, pushing the wing (and thus the airplane) up.
How is the airplane flies?
High air pressure builds up under the wings, and low air pressure goes over the wing, and that makes lift. Thrust from engine pushes it forward.
How does an airplane stay up in the air?
Winglift.Lift is pressure on the wing due differential air pressure below and above wing. This difference results from the difference in curvature of the wing top and bottom..
How do you tell if air pressure is rising o dropping?
When you are going up, air pressure goes down, when you go down, such as under water, air pressure goes up, causing your ears to pop!
Why do we feel pressure in your ears when you go up on an airplane?
As one increases in altitude pressure decreases. The pressure in your ears is then higher than the pressure of the air so one feels tension in their ears.
How airplane can fly in the air?
The airplane fly on the air by 4 main forces ( drag , lift , thrust and weight ) all these forces affect of the performances of the airplane to fly . - the high power of the engine gave a high speed to the airplane on the runway - the design of the wings make the air pressure down the wings is less than the air pressure up the wing ... this make the airplane fly Answered by Alaa Eddin Abd Ellatef Airport Duty Officer Luxor Airport 02 0100 70 42 073
