Abstract
Embodiments are directed to powering a hydraulic motor pump by powering the hydraulic motor pump from a main bus when power is available from the main bus, powering the hydraulic motor pump from an auxiliary power unit starter motor controller during a start-up of the hydraulic motor pump when power from the main bus is unavailable, and powering the hydraulic motor pump from a generator different than the auxiliary power unit subsequent to starting-up the hydraulic motor pump.
