A heater mat for heating an airfoil having a chord, a leading edge, and a trailing edge includes a first zone element configured to heat a first chord-wise segment of the airfoil. The system further includes a second zone element configured to heat a second chord-wise segment of the airfoil that is adjacent to the first chord-wise segment of the airfoil. The system further includes a first zone busbar located at the leading edge of the heater mat and electrically coupled to the first zone element.

An ice protection system for controlling icing on an aircraft surface includes an OAT sensor configured to provide a signal indicative of an OAT, a LWC detector configured to provide a signal indicative of a LWC, an electrothermal device located on the aircraft surface, and an electronic control system configured to determine a critical temperature (TC) at or below which an anti-icing system will be used to preheat the aircraft surface, supply an electrical power having a calculated power level to the electrothermal device, and calculate the power level as being: zero if OAT&#x3e;TC and LWC=0, controlled based on OAT and LWC if OAT&#x3e;TC and LWC&#x3e;0, controlled based on OAT and LWC if OAT&#x3c;TC and LWC&#x3e;0, and controlled based on OAT if OAT&#x3c;TC and LWC=0.
