"Cabin Pressurization" refers to the process of increasing the air pressure in airplane cabins about ambient. In and before WW-2, most planes didn't have this capability, so they were limited to roughly 29,000ft above sea level, where there's barely enough oxygen to support life. Later, O2 systems were added to planes, but the low pressure created a variety of medical problems (barotrauma). With the B-29 (I believe), the ability to pressurize the entire cabin of the plane came into play, which raised the operating ceiling of the plane to well about 30,000ft. Nowadays, most passenger jet equipment pressurizes to .5 atmosphere (7.35PSI) as a bare minimum, and can operatre above 38,000ft. Military craft can of course operate at even higher altitudes.

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.
In 'The Lightning Thief' which god is cabin three dedicated to?
Cabin three at Camp Half-Blood is dedicated to Poseidon. It is the cabin for the children of Poseidon, the Greek god of the sea.
How do passengers on an airplane survive the extremely low air pressure at high altitudes?
In short they don't. Small light unpressurised aircraft fly relatively low, so the air pressure is acceptable. Large aircraft (heavy jets etc) use a pressurised hull, air is pumped into the cabin which is kept at an acceptable density. This is why you hear about explosive decompression, and why aircraft flying at high altitude have oxygen masks which drop from the cabin roof for each passenger in the event of decompression. Without them you would die of oxygen starvation.

Why don't helicopter cabins have to be pressurized?
Helicopters don't generally fly high enough for cabin pressurization to be necessary.
Why Sharp pain in forehead during flight?
Before going into the description of "Sharp Pain" it must be clear that a flight consists of three major phases i.e, takeoff/climb, cruise and descent/landing. All the three phases require differernt PRESSURIZATION SEQUENCES to be maintained inside the cabin to maintain the atmospheric pressure conditions that are almost indentical to that of the sea level, normally 14.7 Psi (however the pressure inside the cabin is slightly lower thatn this value). This "Sharp Pain" in the forehead is associated with these pressurization sequences. The pressurization sequence starts as soon as the aircraft starts running on the runway and the cabin pressure is actually increased (as if the aircraft is diving down below the sea level !!!!). This increase in cabin pressure is necessary to counter the effect of reduced atmospheric pressure at higher altitudes. As a result of this PRE-PRESSURIZATION, a sort of pain is felt in the forehead while the aircraft is still on the ground during takeoff phase !!!! Similar sort of experince is witnessed during the descent phase when the ears start aching because of the increase in cabin pressure as the altitude decreases. In this answer I have assumed that the reader is aware of the concept of CABIN PRESSURIZATION of an aircraft. If this concept isn't clear I would be more than happy to explain it in order to better understand why PRESSURIZATION is necessary which ultimately has to do a lot with the Sharp Pain phenomenon !!!!!!

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.
How are airplane cabins pressurized?
There are air pumps in the outer jacket of the jet engines. Outside fresh air is taken in, compressed by pistons, and forced into ducts that send it into the cabin. The cabin is tightly sealed with carefully calculated exhaust. This allows the small air pump to keep the cabin pressurized. The cabin heaters are usually part of the pressurization system.
What is an aircraft cabin air pressure regulator?
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.
Who takes load when aircraft flies wing or structure?
structure, ultimately all types of load go to structure like lift load, cabin pressurization load, aircraft maneuvering load etc.
How rock is created?
from squeezing and pressurization
What do metamorphic rocks form from?
nonliving processes of heating and pressurization.
What is pressurization unit?
psi. pressure per unit of square inches.
Process by which the shape of a rock changes in response to stress?
pressurization (and plenty of time)
