What altitude is the 787 pressurized to?

Based on that knowledge, the 787 is pressurized to a maximum cabin altitude of 6,000 feet. In cooperation with Denmark Technical University, Boeing challenged the assumption that simply increasing humidity would alleviate complaints about dryness on airplanes.

In the no-bleed architecture, electrically driven compressors provide the cabin pressurization function, with fresh air brought onboard via dedicated cabin air inlets.

The pressurisation system of all series of 737 ensures that the cabin altitude does not climb above approx 8,000ft in normal operation. However in 2005 the BBJ was certified to operate with a reduced cabin altitude of 6,500ft at 41,000ft (?P of 8.99psid above 37,000ft) to increase passenger comfort.

after the flight. Even if you are flying a pressurized aircraft, altitude DCS can occur as a result of sudden loss of cabin pressure (inflight rapid decompression).

One study of eight flights in Airbus A380 aircraft found a median cabin pressure altitude of 6,128 ft (1,868 m), and 65 flights in Boeing 747-400 aircraft found a median cabin pressure altitude of 5,159 ft (1,572 m).

The reduction in air pressure reduces the flow of oxygen across lung tissue and into the human bloodstream. A significant reduction in the normal concentration of oxygen in the bloodstream is called Hypoxia.

Most aircraft cabins are pressurized to an altitude of 8,000 feet, called cabin altitude. Aircraft pilots have access to the mode controls of a cabin pressure control system and – if needed – can command the cabin to depressurize.

Is it at all even possible for it to just drop? According to my company's training materials, an FAA study in the 1960s of depressurization events in business, airline, and military jet transport aircraft determined that the odds of experiencing cabin depressurization were one in 54300 flight hours.

An exclusive in-flight The A350's cabin is also the quietest on a twin-aisle aircraft, and its advanced technology delivers the highest possible air quality with optimised cabin altitude (6,000 ft.), optimum temperature and humidity, with the air being renewed every two to three minutes.

A particularly quiet cabin, more free space and privacy, lighting that adapts to your biorhythm - and a generous feeling of space that is unparalleled. On board the Boeing 787-9, you can expect a new, comfortable travel experience and many innovations that will make your flight even more relaxing in the future.

Most planes flying today use a cabin pressure control system that ensures safe and normal breathing for everyone onboard during flight. The general rule is that planes should have cabin pressurization when they go above 10,000 to 14,000 feet.

For best protection, you are encouraged to use supplemental oxygen above 10,000 feet MSL. At night, because vision is particularly sensitive to diminished oxygen, a prudent rule is to use supplemental oxygen when flying above 6,000 feet MSL. So, when you fly at high altitudes, supplemental oxygen is the only solution.

If the plane is somehow kept pressurized, the cabin pressure is usually equivalent of 6000–8000 ft, which is lower pressure than the outside at sea level. Which means as soon as you unlock the door, it will swing inwards with a lot of force, as air from outside rushes in to re-pressurize the cabin.
