Abstract: A rotorcraft includes an avionics control unit (ACU) and multiple power distribution units (PDUs) electrically connected to an electrical bus, wherein each PDU of the multiple PDUs is electrically connected to a respective multiple electrical loads, and wherein each PDU of the multiple PDUs is configured to receive commands from the ACU to couple or decouple one or more of its respectively connected multiple electrical loads from the electrical bus. The ACU is configured to send commands to the multiple PDUs to couple or decouple a first set of electrical loads and to couple or decouple a second set of electrical loads from the electrical bus, wherein the coupling or decoupling of the first set and the coupling or decoupling the second set is based on a first priority of the first set and a second priority of the second set, respectively.
