one or more heaters configured to be coupled to a surface of a slat of a wing of the aircraft; and

a controller coupled to the one or more heaters and coupled to a plurality of sensors that provide sensor data regarding conditions associated with the aircraft to the controller, wherein the controller is configured to, in response to a first determination by the controller based on the sensor data indicating presence of an icing condition, determine a setpoint temperature for a first location of an outer surface of the slat configured to be heated by a heater of the one or more heaters and to control power provided to the heater based on the setpoint temperature and the sensor data, wherein the setpoint temperature for the first location is determined to cause a second location of the outer surface of the slat, which is heated by the heater and is located at a particular distance from the first location, to remain above a threshold temperature based on a projected temperature profile of the outer surface heated by the heater.
