  2. Cabin pressurization - Wikipedia

    en.wikipedia.org/wiki/Cabin_pressurization

    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.

    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.

  5. Bleed air - Wikipedia

    en.wikipedia.org/wiki/Bleed_air

    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 ...

  6. Air cycle machine - Wikipedia

    en.wikipedia.org/wiki/Air_cycle_machine

    The power for the air conditioning pack comes from the reduction of the pressure of the incoming bleed air relative to that of the cooled air exiting the system; typical differentials are from about 30 psi or 210 kPa to about 11 psi or 76 kPa. [1] The next step is to dehumidify the air.

  9. Pitot–static system - Wikipedia

    en.wikipedia.org/wiki/Pitot–static_system

    A pitot–static system generally consists of a pitot tube, a static port, and the pitot–static instruments. [1] Other instruments that might be connected are air data computers, flight data recorders, altitude encoders, cabin pressurization controllers, and various airspeed switches. Errors in pitot–static system readings can be extremely ...
