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.
In aeronautics, an environmental control system (ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers. Additional functions include the cooling of avionics , smoke detection , and fire suppression .
Its Garrett AiResearch cabin pressurization system gives the equivalent of 11,000 feet (3,400 m) at the aircraft's operational ceiling of 24,000 feet (7,300 m). [6] As a demonstration of its high performance, the second production aircraft was flown non-stop from New York to the Paris Air Show in June 1967, the flight taking 13 hours 10 minutes.
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 ...
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 ...
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] Hypoxia can be produced in a hypobaric chamber. This can be useful ...
[1] [2] Bleed air from that system can be utilized for internal cooling of the engine, cross-starting another engine, engine and airframe anti-icing, cabin pressurization, pneumatic actuators, air-driven motors, pressurizing the hydraulic reservoir, and waste and water storage tanks. Some engine maintenance manuals refer to such systems as ...
The pressurization system was fed from a large scoop intake below the engine into engine driven compressors. The pressurized cabin, slightly wider than high had an average diameter of about 2.45 m (8 ft 0 in) [1] allowing the two observers comfortable working room and a total cabin volume of 11 m 3 (390 cu ft).
