Abstract
A fuel system for an aircraft comprises a boost pump, a main fuel pump and a motive pump. The boost pump receives fuel from a storage unit. The main fuel pump receives fuel from the boost pump and delivers fuel to a distribution system. The motive fuel pump receives fuel from the boost pump, routes fuel through the storage unit, and delivers fuel to an actuator. A method for delivering fuel in an aircraft comprises pumping fuel from a fuel tank to a distribution system using a main pump, pumping fuel from a fuel tank to an actuator using a motive pump, and routing fuel from the actuator to the main pump.
