It maintains the cabin pressure to the air pressure at 8000 ft. Without pressurization, you would get hypoxia (The Lack Of Oxygen) Get light headed, pass out, then possibly die. As you go higher the atmospheric pressure drops. Payne Webber the Golfer died when the cabin pressure regulator failed.

What is the air pressure in an aircraft?
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.
What is the cabin pressure in a aircraft during ceiling altitude of flight?
Air craft cabin is fully pressurized.
Is the air pressure of a aircraft the same as the air pressure outside above and below?
No, the air pressure inside an aircraft is regulated to be at a comfortable level for passengers, which is usually lower than the air pressure at high altitudes. The difference in pressure is controlled by the aircraft's pressurization system to maintain a safe and habitable environment inside the cabin.
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.
What is differential air pressure?
Differential air pressure is a term of comparison. It may be stated as "the difference in air pressure between..." and finished from there. Let's look at a sentence and then break it down. "The differential air pressure across the body of the 747 is a cause of concern over the life of the aircraft." A jet at altitude has a pressurized cabin. The outside air pressure is very low. (Think Mount Everest. Almost no one climbs it without suplimental oxygen.) There is a difference between the air pressure inside the cabin and the air pressure outside the cabin. This is an instance of differential air pressure. The differential air pressure puts stress on the body of the plane. When the aircraft is back on the ground, the differential pressure disappears. The alternating application and neutralization of stress across the hull damages the structure over the life of the airframe. The differential pressure is the difference between the pressure of the air in the (pressurized) cabin at altitude and the pressure of outside air at that altitude.
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.
What is a IMA ramp?
An IMA ramp is a device that enables the inflow of outside air into an aircraft cabin during flight. This helps regulate cabin pressure and maintain a comfortable environment for passengers and crew.
HOW is Oxygen provided in aircraft?
On commercial airliners the jet turbines are also used to cram air into small ducts (at very high pressure) which is mixed with recycled air and then bled back into the cabin through the air conditioning. On commercial airliners the jet turbines are also used to cram air into small ducts (at very high pressure) which is mixed with recycled air and then bled back into the cabin through the air conditioning.
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 does a regulator do on an air compressor line?
It regulates the air pressure coming out of the compressor. Usually, they are adjustable and used to lower the air pressure.
What is the air cycle?
The air cycle is a process that involves the cooling and compressing of air to remove moisture and contaminants before it is used in aircraft environmental control systems. It helps to regulate the temperature and pressure of the air supplied to the cabin for passenger comfort and safety during flight.
