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). The total annual usage of de-icing fluids in the U.S. is estimated to be approximately 25 million US gallons (95,000,000 L), broken down as follows (figures from 2008, adjusted to show totals for ...
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 ...
Ice buildup can change the shape of airfoils and flight control surfaces, degrading control and handling characteristics as well as performance. An anti-icing, de-icing, or ice protection system either prevents formation of ice, or enables the aircraft to shed the ice before it becomes dangerous.
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 ...
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.

[1] [2] Geer began working on the deicing problem in 1927. By 1929 the work showed enough promise that he won support from the Guggenheim fund, and by 1930 he had made the first flight test. [ 3 ] He was able to persuade C. W. Leguillon of the B. F. Goodrich Tire and Rubber Company that his system worked, and a commitment to develop the device.
