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.

A cabin humidity control system may be added to the ECS of some aircraft to keep relative humidity from extremely low levels, consistent with the need to prevent condensation. [8] Furthermore, the Boeing 787 and Airbus A350, by using more corrosion-resistant composites in their construction, can operate with a cabin relative humidity of 16% on ...
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.
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 ...
The aircraft is pressurized and was designed for a 6.5 psi (45 kPa) differential pressure, giving an 8,000 ft (2,438 m) cabin pressure at its maximum altitude of 28,000 ft (8,534 m). [ 8 ] The turbine version of the Evolution is powered by the 750 hp (559 kW) Pratt & Whitney PT6A-135A and has a maximum cruise of 300 kn (556 km/h) at 25,000 ft ...
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 ...
A photo taken by passenger Jaci Purser after the Delta flight she was on returned to the airport due to a cabin pressure issue that caused bloody noses and other problems for passengers. - Jaci Purser
The company developed and produced the cabin pressure system for the B-29 bomber, the first production bomber pressurized for high altitude flying. By the end of World War II, AiResearch engineers had developed air expansion cooling turbines for America's first jet aircraft, the Lockheed P-80 Shooting Star. During World War II, Garrett ...
