An airliner fuselage, such as this Boeing 737, forms an almost cylindrical pressure vessel.. Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for humans flying at high altitudes.
Generally, old age tends to reduce the efficiency of the pulmonary system, and can cause the onset of hypoxia symptoms sooner. [3] Smoking drastically reduces oxygen intake efficiency, and can have the effect of reducing tolerance by 1,000–2,000 metres (3,300–6,600 ft). [ 4 ]
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 ...
The decision by Alaska Airlines to stop flying one of its planes over the Pacific Ocean to Hawaii due to warnings from a cabin-pressurization system — yet keep flying it over land — is raising ...
Some Delta Air Lines passengers are recovering after a pressurization issue on a flight from Salt Lake City, Utah, to Portland, Oregon, caused bloody noses and other issues, according to airline ...
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 ...
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.
The cabin pressurization was provided by bleeding air from the engines' turbo supercharger, the compressor outlet fed into the cabin and was controlled by the flight engineer. [4] This system was able to maintain a cabin altitude of 12,000 ft (3,658 m) while flying at 30,000 ft (9,144 m). [ 5 ]
