The pressure differential varies between aircraft types, typical values are between 540 hPa (7.8 psi) and 650 hPa (9.4 psi). [35] At 39,000 ft (11,887 m), the cabin pressure would be automatically maintained at about 6,900 ft (2,100 m), (450 ft (140 m) lower than Mexico City), which is about 790 hPa (11.5 psi) of atmosphere pressure.

In 1996, the FAA adopted Amendment 25–87, which imposed additional high-altitude cabin-pressure specifications, for new designs of aircraft types. [25] For aircraft certified to operate above 25,000 feet (FL 250; 7,600 m), it "must be designed so that occupants will not be exposed to cabin pressure altitudes in excess of 15,000 feet (4,600 m ...
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.
In the aftermath of the incident aboard an Alaska Airlines 737 Max 9, we look at what happens when an aircraft experiences a sudden loss of cabin pressure and the risks for those on board.
The stress in the skin of the fuselage is determined by the cabin differential and the thickness of the skin. If a pressurized aircraft is designed and approved for a high cabin differential it must have thick skins, or skins made of stronger material than would be the case if it was designed and approved for a low cabin differential.

A rate controller enables the crew to select the rate pressurization of the cabin within preset limits. The normal pressure relief valve will open at 8.9 psi differential pressure and the safety outflow valve will open at 9.2 psi differential pressure which is the maximum allowable differential pressure.
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 ...
