The amount of fluid necessary to de-ice an aircraft depends on a wide variety of factors. 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.
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.
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 ...
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.
The area just aft, the shedding zone, is normally kept below freezing, causing the streaming water to freeze and collect as ice. During a de-ice cycle the voltage is increased, raising the temperature of this aft shedding zone, melting the ice bond and shedding the ice via aerodynamic force. Once power is removed from the heater, the shedding ...
There was no verbal inquiry by the captain about the status of the icing conditions or the aircraft deice/anti-icing systems. At 15:55:42, the first officer commented, "we still got ice." This comment was not verbally acknowledged by the captain. The CVR indicated that the flightcrew had no further discussions regarding the icing conditions.

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.
