In aviation, ground deicing of aircraft is the process of removing surface frost, ice or frozen contaminants on aircraft surfaces before an aircraft takes off. This prevents even a small amount of surface frost or ice on aircraft surfaces from severely impacting flight performance.
Deicing a large commercial aircraft typically consumes between 500 and 1,000 US gallons (1,900 and 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).
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 ...
This system takes as little as 1 second per surface and only 33 seconds to deice the entire aircraft using a 60-second cycle. Once armed, the system is digitally controlled with automatic shedding cycles activating at 41 °F.
Infratek is a system for removing ice from aircraft using heat (infrared radiation). Infrared panels powered by natural gas are installed inside a big hangar -like tent with openings in both ends. When the aircraft is inside, the infrared rays will melt the ice off its wings and body.
The Federal Aviation Administration has flagged more safety issues for two troubled families of Boeing planes, the latest in a series of issues at the embattled aircraft maker.
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.

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.
