The pressure inside the cabin is technically referred to as the equivalent effective cabin altitude or more commonly as the cabin altitude. This is defined as the equivalent altitude above mean sea level having the same atmospheric pressure according to a standard atmospheric model such as the International Standard Atmosphere. Thus a cabin ...
Cabin doors are designed to make it nearly impossible to lose pressurization through opening a cabin door in flight, either accidentally or intentionally. The plug door design ensures that when the pressure inside the cabin exceeds the pressure outside, the doors are forced shut and will not open until the pressure is equalized. Cabin doors ...
In more severe cases, hyperbaric oxygen therapy following standard recompression protocols is indicated. Decompression sickness in aviation most commonly follows flights in non-pressurized aircraft, flights with cabin pressure fluctuations, or in individuals who fly after diving. Cases have also been reported after the use of altitude chambers.
At higher altitudes, the air is thinner, which is why oxygen masks deploy in the event of a loss of cabin pressure. Below 10,000 feet, passengers will be able to breathe normally in a ...

Passengers said a pressurization issue on a Delta Air Lines flight Sunday left them with bloody noses and ears. A spokesperson for the airline company said that Flight 1203 from Salt Lake City to ...
That means that the pressure is 10.9 pounds per square inch (75 kPa), which is the ambient pressure at 8,000 feet (2,400 m). Note that a lower cabin altitude is a higher pressure. The cabin pressure is controlled by a cabin pressure schedule, which associates each aircraft altitude with a cabin altitude.
Bleed air in aerospace engineering is compressed air taken from the compressor stage of a gas turbine, upstream of its fuel-burning sections.Automatic air supply and cabin pressure controller (ASCPC) valves bleed air from low or high stage engine compressor sections; low stage air is used during high power setting operation, and high stage air is used during descent and other low power setting ...
