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.
De-icing fluids containing thickeners (types II, III, and IV) are also known as anti-icing fluids, because they are used primarily to prevent icing from re-occurring after an initial deicing with a type I fluid. TKS fluid is similar to type I fluid and is used by in-flight TKS ice protection systems. [5]
Aircraft that regularly operate in icing conditions have systems to detect and prevent ice forming (anti-icing) and/or remove the ice accumulation after it has formed (de-icing). This can be achieved by heating the spaces in internal structure with engine bleed air, chemical treatment, electrical heating and expansion/contraction of the skin ...
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 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 ...
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 ...
