1. A fluid pump system for an aircraft, the system comprising:
a gearbox component for a rotor, the component being pivotable between an airplane-mode orientation and a helicopter-mode orientation and having first and second fluid scavenge ports, each scavenge port in fluid communication with a selected interior portion of a fluid sump of the component for withdrawing fluid from the associated portion of the sump, the portions being spaced from each other; and
a valve for controlling a flow rate of fluid through each scavenge port;
wherein the valve allows a first flow rate through the first scavenge port and allows a second flow rate through the second scavenge port when the component is in a first angular orientation; and
wherein the valve allows a third flow rate through the first scavenge port and allows a fourth flow rate through the second scavenge port when the component is in a second angular orientation.
