  2. Ground deicing of aircraft - Wikipedia

    en.wikipedia.org/wiki/Ground_deicing_of_aircraft

    Mechanical removal of snow from a Learjet 35. The weight of snow on the tailplane has raised the nose into the air. Mechanical deicing using tools such as brooms, scrapers, ropes, and mops can be used to minimize the amount of fluid or heat-based deicing required. However care must be taken to avoid damaging surfaces, antennas, pitot tubes, etc.

  3. Ice protection system - Wikipedia

    en.wikipedia.org/wiki/Ice_protection_system

    Propeller blade with fluid deicing system – glycol is sprayed from hub outward to cover blades. Sometimes called a weeping wing, [6] running wet, or evaporative system, these systems use a deicing fluid—typically based on ethylene glycol or isopropyl alcohol to prevent ice forming and to break up accumulated ice on critical surfaces of an ...

  4. Deicing - Wikipedia

    en.wikipedia.org/wiki/Deicing

    An Aeroflot Airbus A330 being deiced at Sheremetyevo International Airport Econ Salt Spreader. Deicing is the process of removing snow, ice or frost from a surface. Anti-icing is the application of chemicals that not only deice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.

  5. Aircraft deicing fluid - Wikipedia

    en.wikipedia.org/wiki/Aircraft_deicing_fluid

    In ground deicing of aircraft, aircraft deicing fluid (ADF), aircraft deicer and anti-icer fluid (ADAF) or aircraft anti-icing fluid (AAF) are commonly used for both commercial and general aviation. [ 1 ] [ 2 ] Environmental concerns include increased salinity of groundwater where de-icing fluids are discharged into soil, and toxicity to humans ...

  6. Deicing boot - Wikipedia

    en.wikipedia.org/wiki/Deicing_boot

    A deicing boot is a type of ice protection system installed on aircraft surfaces to permit a mechanical deicing in flight. Such boots are generally installed on the leading edges of wings and control surfaces (e.g. horizontal and vertical stabilizer ) as these areas are most likely to accumulate ice which could severely affect the aircraft's ...

  7. Snow removal - Wikipedia

    en.wikipedia.org/wiki/Snow_removal

    When properly performed, anti-icing can significantly reduce the amount of salt required and allow easier removal by mechanical methods, including plowing. [1] The de-icing of roads has historically been accomplished by snowplows or specially designed dump trucks that spread salt, often mixed with sand and gravel, onto slick roads.

  8. Icing (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Icing_(aeronautics)

    Mechanical means, which may be as simple as using a broom or brush to remove snow; Application of deicing fluid or even hot water to remove ice, snow, etc. Use of infrared heating to melt and remove contaminants; Putting the aircraft into a heated hangar until snow and ice have melted

  9. 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 ...
