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 ...
Unmanned aircraft are more sensitive and susceptible to icing compared to manned aircraft. [8] The main differences between UAVs and manned aircraft when it comes to icing are: Size and weight: Small aircraft accumulate ice faster, and more ice per unit area, compared to large aircraft. UAVs are typically smaller than manned aircraft and ...
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 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.
Fuel system icing inhibitor (FSII) is an additive to aviation fuels that prevents the formation of ice in fuel lines. FSII is sometimes referred to by the registered, genericized trademark Prist. Jet fuel can contain a small amount of dissolved water that does not appear in droplet form. As an aircraft gains altitude, the temperature drops and ...
The structural icing of an aircraft is largely determined by three factors: supercooled liquid water content, which decides how much water is available for icing; air temperature, with half of all reported icing occurring between −8 °C (18 °F) and −12 °C (10 °F); and droplet size, with small droplets influencing aircraft's leading edges ...
