Dreamliner Cabin Pressure

The comfortable feel of the cabin is reinforced by soft led lighting.

Dreamliner cabin pressure. And a little more on the workings of this system. 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. The dreamliner s cabin pressure simulates an elevation of just 6 000 feet a 20 percent reduction over similar aircraft.

A non flightworthy static test airframe was built. Exterior and interior altitude profile on a typical flight. As part of the engine operation some air is bled out of the high pressure compression stage and then into the air conditioning system.

There is a cockpit humidifier switch and cabin air humidification is fully automatic source. To lower the cabin altitude we actually. On september 27 2008 the fuselage was successfully tested at 14 9 psi 102 7 kpa differential which is 150 percent of the maximum pressure expected in commercial service.

Thus a cabin altitude of zero would have the pressure found at mean sea level which is taken to be 101 325 kilopascals 14 696 psi. This has tremendous benefits for the passenger experience. For the dreamliner boeing cut that down to 6 000 feet.

The pressure inside the cabin is technically referred to as the equivalent effective cabin altitude or more commonly as the cabin altitude. On a typical flight as the aircraft climbs to 36 000 feet the interior of the plane climbs to between 6000 8000 feet. In december 2008 the 787 s maintenance program was passed by the faa.

Travellers will feel less fatigued more alert and better able to work en route in the 787 dreamliner. Currently most airliners have cabin air pressure equivalent to that of an altitude of 8 000 feet. Pressurizing and refreshing the air in an aircraft cabin whenever an aircraft climbs and reaches its cruise altitude the atmospheric pressure drops down to about four pounds per square inch psi while the pressure on board remains at about 11 psi simulating the atmosphere of around 8 000 feet inside the aircraft.
