Aircraft that operate in weather conditions where ice is likely to form must be provided with ice protection technology. This protection may be in the form of anti-icing systems, or de-icing systems. An anti-icing system prevents the formation of ice on the airplane, while a de-icing system removes ice that has already formed. In this blog we will focus on de-icing boots and TKS fluid systems.  A de-icing system has two pertinent advantages. First, it can utilize a variety of means to transfer energy used to remove the ice.
