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).
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.
The use of deicing boots may enable an aircraft to be certified for flight into known icing conditions. However, they may not be sufficient to handle extremely severe icing, where ice can accumulate faster than the boots can shed it, or it accumulates on non-booted surfaces to the point where there is a dangerous loss of lift or control, or ...
An Aeroflot Airbus A330 being de-iced at Sheremetyevo International Airport Econ Salt Spreader. De-icing is the process of removing snow, ice or frost from a surface. 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.
Icing conditions are characterized quantitatively by the average droplet size, the liquid water content and the air temperature. These parameters affect the extent, type and speed that characterize the formation of ice on an aircraft. Federal Aviation Regulations contain a definition of icing conditions [4] that some aircraft are certified to ...
Aircraft icing increases weight and drag, decreases lift, and can decrease thrust. Ice reduces engine power by blocking air intakes. When ice builds up by freezing upon impact or freezing as runoff, it changes the aerodynamics of the surface by modifying the shape and the smoothness of the surface which increases drag, and decreases wing lift ...
Davis DA-2 at Airventure 2008. Davis DA-2A. The Davis DA-2 is a light aircraft designed in the United States in the 1960s and was marketed for homebuilding. [1] While it is a low-wing monoplane of largely conventional design with fixed tricycle undercarriage, the DA-2 is given a distinctive appearance by its slab-like fuselage construction and its V-tail.

The President's plane, the Independence, a Douglas DC-6, was one of the first production models utilizing a thermal de-ice system. [8] Pressurized cabins allowed aircraft to fly above icing levels, and improved ground de-icing fluids helped diminish the ice hazards. Satisfied with his de-icing work, Rodert turn to his new crusade: reducing the ...
