Claim:
1. A method of load shedding in an aircraft, being a method of load shedding to cut off supply of power to a plurality of target devices selected from a device group, the power generated by generators included in the aircraft and supplied to the device group, the method of load shedding comprising: a failure detection step of detecting a failure hindering the generator from generating; and a load-shedding step, after the failure is detected in the failure detection step, of executing the load shedding on the basis of determination of necessity of the load shedding, wherein the load-shedding step includes: a first period load-shedding step, a processing time of which is in units of a predetermined first period; a second period load-shedding step, a processing time of which is in units of a second period longer than the first period; a determination step of determining that the load shedding is needed on the basis that a state where power consumption consumed by the devices exceeds a predetermined power-generation capacity continues for a predetermined monitoring time; and an execution step of executing, if the load shedding is determined to be needed in the determination step, the load shedding step-by-step while advancing a priority given to the target devices until the power consumption falls below the power-generation capacity; wherein in the first period load-shedding step, the power-generation capacity is set at a capacity in accordance with a property of the generators associated with the second period, and in the second period load-shedding step, the power-generation capacity is set at a capacity in accordance with a stationary property of the generators.
