The 787's internal cabin pressure is the equivalent of 6,000 ft (1,829 m) altitude resulting in a higher pressure than for the 8,000 ft (2,438 m) altitude of older conventional aircraft; [62] according to a joint study performed by Boeing and Oklahoma State University, such a level significantly improves comfort levels.
Flight levels [3] are described by a number, which is the nominal altitude, or pressure altitude, in hundreds of feet, and a multiple of 500 ft. Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320". In metre altitudes the format is Flight Level xx000 metres.
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.
An aircraft cabin is the section of an aircraft in which passengers travel. [1] Most modern commercial aircraft are pressurized, as cruising altitudes are high enough such that the surrounding atmosphere is too thin for passengers and crew to breathe. [2] In commercial air travel, particularly in airliners, cabins may be divided into several parts.
With a steady stream of global heat records, cabins may become too hot to board. But is there really a limit?
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 ...
What a year 2024 has already been for aviation. In just the first two weeks of January, we saw two major incidents: a Japan Airlines jet that struck a Japanese Coast Guard plane on the runway at ...
