Deicing a large commercial aircraft typically consumes between 500 US gallons (1,900 L) and 1,000 US gallons (3,800 L) of diluted fluid. The cost of fluid varies widely due to market conditions. The amount de-icing service companies charge end users is generally in the range of US$8 to US$12 per diluted gallon (US$2.10 to US$3.20 per liter).
Pneumatic boots are appropriate for low and medium speed aircraft, without leading edge lift devices such as slats, so this system is most commonly found on smaller turboprop aircraft such as the Saab 340 and Embraer EMB 120 Brasilia. Pneumatic de-icing boots are sometimes found on other types, especially older aircraft.
Operation of deicing boots De-icing rubber boots on the wing leading edge of a Beechcraft 350. A deicing boot is a type of ice protection system installed on aircraft surfaces to permit a mechanical deicing in flight.
Fluid based aircraft de-icing vehicle. In most cases ground-based deicing is accomplished by spraying the aircraft with an aircraft deicing fluid just prior to departure. For commercial aircraft this fluid is usually applied to contaminated surfaces using a specially designed machine. For smaller aircraft a handheld spray applicator may suffice.

Anti-icing is the application of chemicals that not only de-ice 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.
The aircraft is equipped with a de-icing system, which uses a mixture of bleed air from the engines, TKS fluid for general airframe, and AC electric windshield heating to prevent ice formation. Weather radar was incorporated into the aircraft's avionics. [5]
The TKS system utilised a de-icing fluid that was made to seep through a porous strip along the wing and tail surface leading edges where it would then be spread out by the airflow, an early example of the TKS system's use being on the Avro Shackleton maritime patrol aircraft.
Lewis August Rodert (1906–1973) of the National Advisory Committee for Aeronautics (NACA) was awarded the 1946 Collier Trophy for the design, development, and practical application of a thermal aircraft anti-icing system.
