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.
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.
Time of useful consciousness (TUC), also effective performance time (EPT), is defined as the amount of time an individual is able to function effectively (e.g. perform flying duties) in an environment of inadequate oxygen supply. [1]
It was the second American aircraft to feature cabin pressurization. [1] It was initially described as a "supercharged cabins" by the Army. The XC-35 was a development of the Lockheed Model 10 Electra that was designed to meet a 1935 request by the United States Army Air Corps for an aircraft with a pressurized cabin. [2]
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 ...
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 ...
