A method of monitoring an ice protection system (10) of a rotorcraft or an aircraft includes applying heat to rotating blades of the rotorcraft or the aircraft according to a heater duty cycle and determining an anticipated ice shed time for ice to shed from the rotating blades. Torque of the rotating blades is sensed, and an actual ice shed time for ice to shed from the rotating blades is determined based on the sensed torque. A status of the ice protection system (10) is determined based on the anticipated ice shed time and the actual ice shed time, and the status of the ice protection system (10) is output for consumption by a consuming system (70).
