    摘要: An automatic engine driven pump (EDP) depressurization system for an aircraft is disclosed. The aircraft includes at least two EDPs (30a) driven by a main engine for converting mechanical power provided by the main engine into hydraulic power for distribution by a hydraulic system. The EDP depressurization system includes a depressurization device (70a) corresponding to each of the at least two EDPs (30a) and a control module (80). The depressurization devices (70a) are each energized to depressurize a respective EDP (30a). The control module (80) is in signal communication with each of the depressurization devices (70a). The control module (80) includes control logic for automatically generating a depressurization signal that energizes one of the depressurization devices based on a plurality of operational conditions of the aircraft.
