While the pressure outside the aircraft is very low, cabin pressurization allows pilots to pressurize the aircraft cabin to about 11.5 psi. They try to keep the cabin pressurized to make it seem like the air at around 7,000 feet. That's why your ears pop.

Is the air pressure of a aircraft the same as the air pressure outside above and below?
An aircraft don't have air pressure.Why you ask?Because an aircraft is not a living thing.Who writes these questions?
What does an aircraft's altimeter indicate?
air pressure
Why do your ears hurt when you come on a aircraft?
your ears hurt when you are in an aircraft because of the change in air pressure when you are in the air
What Happens if a Plane Goes Higher Than it's Designed To?
As the air pressure outside the aircraft decreases, & the air pressure inside the aircraft remains the same, it remains very high inside the aircraft in comparison to the outside, so in the end, the fuselage will explode apart, because the air pressure outside is not enough to counter act it & push against the force of the air pressure inside the aircraft which is pushing outwards.
How aircraft speed and altitude can alter air pressure and how it complies with bernoulii's principle?
Aircraft speed and altitude cannot alter air pressure and how it complies with Bernoulli's principle. Aircraft speed decreases the pressure on the wings of the aircraft but this does not alter air pressure.
How is aircraft flying?
Aircraft have wings called airfoils. When air passes over these wings, the lower half of air has low pressure and the top has high pressure. Low pressure moves towards high pressure. And that force lifts the plane.
How is the air speed of an airplane calculated?
Airspeed is calculated by measuring the same force you feel when you put your hand out a car window. The long tube you see sticking out the front of many aircraft(pitot tube) is there to sample the air pressure in front of the aircraft, free of any aerodynamic interference from the fuselage. This ram air pressure(pitot pressure) is the air pressure that's hitting the nose of the aircraft. It's then compared to a static air source (usually inside the fuselage) and from the difference the aircraft's speed can be calculated after biasing the results for daily differences in ambient air pressure.
How can air pressure affect the window glass of an airplane?
Other than the force of the air on the windscreen as the aircraft moves forward through the air (a function of speed and air density), the primary affect of air pressure on window glass in an aircraft is from the force of cabin air pressure pushing out against the window. This force can be in the neighborhood of 8 pounds per square inch in the average commercial aircraft. Because of this rather significant force, windows in pressurized aircraft generally are small and sturdily built.
Can a plane stand in air?
Helicopters and some STOL aircraft can stand still in the air. If an actual winged aircraft does this it will 'stall' because air pressure is not moving over the wings.

What is simple aircraft refrigeration system?
a simple aircraft refrigeration system is an air refrigeration system, where air is used as the working fluid. the compressor of the aircraft is used to compress the air isentopicaly by ramming process, thus increasing its pressure from p1 to p2. constant pressure heat rejection takes place in a heat exchanger, thus redusing its temperature. now it is isentropicaly expanded using the turbine to the cabin pressure. this air mixes with the air in the cabin and reduses the temperature.
