An ice protection system for an aircraft includes an ice detector (16) disposed in an external aircraft surface, a temperature sensor (126), and a controller (102). The ice detector includes an ice sensor (130). The controller includes an icing threshold module (118) which receives a temperature measurement from the temperature sensor, receives an ice accretion signal from the ice sensor, compares the temperature measurement to an icing threshold temperature, and determines whether the temperature measurement is above the icing threshold temperature. The controller suppresses an icing conditions alert if the temperature measurement exceeds the icing threshold temperature.
