  4. 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 ...

  7. Uncontrolled decompression - Wikipedia

    en.wikipedia.org/wiki/Uncontrolled_decompression

    Cabin doors are designed to make it nearly impossible to lose pressurization through opening a cabin door in flight, either accidentally or intentionally. The plug door design ensures that when the pressure inside the cabin exceeds the pressure outside, the doors are forced shut and will not open until the pressure is equalized. Cabin doors ...

  8. Environmental control system - Wikipedia

    en.wikipedia.org/wiki/Environmental_control_system

    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 .

  9. Emergency oxygen system - Wikipedia

    en.wikipedia.org/wiki/Emergency_oxygen_system

    Most commercial aircraft that operate at high flight altitudes are pressurized at a maximum cabin altitude of approximately 8,000 feet. On most pressurized aircraft, if cabin pressurization is lost when the aircraft is flying at an altitude above 4,267 m (14,000 feet), compartments containing the oxygen masks will open automatically, either above or in front of the passenger and crew seats ...
