Abstract: Apparatus and associated methods relate to providing redundant heating elements to a surface of an aircraft skin for the purpose of controlling ice accretion thereon. Each of the redundant heating elements can be used alone or in conjunction with the other(s) of the redundant heating elements. In some embodiments, a second heating element can be used if or when a first heating element fails and/or is insufficient to perform the heating task. In some embodiments, the first and second heating elements can be controlled so as to create a heating profile of the surface of the aircraft skin. A heat controller provides electrical control signals to the first and second heating element. In some embodiments, the heat controller can provide such electrical control signals in response to detected ice accretion, flight conditions, and/or detected atmospheric conditions.
