Abstract: A system and method for controlling power includes a power source, a plurality of primary control circuits (20a - 20n), a load, at least one secondary control circuit (22a - 22n), a switch circuit (24), and a control channel. The plurality of primary control circuits (20a - 20n) are connected to control load power from the power source to respective ones of a plurality of load power inputs. The load is configured to receive power from the plurality of load power inputs. The at least one secondary control circuit (22a - 22n) is connected to the power source, and the switch circuit (24) is connected between the at least one secondary control circuit (22a - 22n) and the plurality of load power inputs. The control channel is configured to control the switch circuit (24) to connect the at least one secondary control circuit (22a - 22n) to a selected one of the plurality of load power inputs.

Abstract: 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).
