An ice protection system (50) for controlling icing on an aircraft surface includes an OAT sensor (40) configured to provide a signal indicative of an OAT, a LWC detector (44) configured to provide a signal indicative of a LWC, an electrothermal device (56) located on the aircraft surface, and an electronic control system (52) 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 > TC and LWC = 0, controlled based on OAT and LWC if OAT > TC and LWC > 0, controlled based on OAT and LWC if OAT < TC and LWC > 0, and controlled based on OAT if OAT < TC and LWC = 0.
