A system and method are provided to selectively control lubricant supply flow to a rotating machine that is installed in an aircraft having ram air turbine that is movable between at least a deployed position and a stowed position. A controller determines at least when the ram air turbine is in the deployed position, and determining when rotational speed of the rotating machine exceeds a predetermined value. The electric motor driven lubrication pump is at least selectively energized to control the measured lubricant pressure to a predetermined minimum pressure at least when the ram air turbine is deployed and the rotational speed exceeds the predetermined value.
