Is the ice equipment on an aircraft typically designed for de-icing or anti-icing?

The ice equipment on an aircraft is primarily designed for anti-icing purposes. Anti-icing systems work to prevent the formation of ice on critical surfaces of the aircraft during flight. This is essential for maintaining aerodynamic performance and ensuring the safety of the aircraft. Anti-icing systems, such as heated surfaces or systems that apply a liquid or chemical to aircraft surfaces, create an environment that inhibits ice adherence and accumulation.

While some aircraft may also employ de-icing systems, which actively remove ice that has already formed, the main focus of ice protection systems is to prevent ice from forming in the first place. This proactive approach is especially crucial during flight operations in icing conditions, as ice build-up can significantly affect performance, stall characteristics, and control.

The other choices do not fully encapsulate the primary design intent of ice equipment on aircraft. Systems that address neither de-icing nor anti-icing do not exist in the context of operational aircraft, as icing prevention is a critical aspect of flight safety procedures.
