Abstract

A system is provided for managing an amount of stored energy in a powered system. The powered system is configured to complete a mission from an initial stage to a final stage. The system includes a controller including a memory configured to store a plurality of handling stages. The controller is configured to determine the stored energy at the initial stage based upon the initial stage and a handling stage positioned between the initial stage and the final stage, and selected from among the plurality of handling stages stored in memory. The stored energy is necessary to propagate the powered system from the initial stage to the handling stage upon the occurrence of an anomaly in the powered system. Additionally, a method and computer readable media are provided for managing an amount of stored energy in a powered system.
