  2. Cabin pressurization - Wikipedia

    en.wikipedia.org/wiki/Cabin_pressurization

    The air is cooled, humidified, and mixed with recirculated air by one or more environmental control systems before it is distributed to the cabin. [1] The first experimental pressurization systems saw use during the 1920s and 1930s. In the 1940s, the first commercial aircraft with a pressurized cabin entered service. [2]

  3. Uncontrolled decompression - Wikipedia

    en.wikipedia.org/wiki/Uncontrolled_decompression

    Explosive decompression occurs typically in less than 0.1 to 0.5 seconds, a change in cabin pressure faster than the lungs can decompress. [1] [3] Normally, the time required to release air from the lungs without restrictions, such as masks, is 0.2 seconds. [4]

  4. Environmental control system - Wikipedia

    en.wikipedia.org/wiki/Environmental_control_system

    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 ...

  5. Bleed air - Wikipedia

    en.wikipedia.org/wiki/Bleed_air

    [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 ...
