    Abstract: A lubrication system for a gas turbine engine according to an example of the present disclosure includes, among other things, a pump that moves a lubricant, a lubricant tank that stores the lubricant, a first engine component and a second engine component each requiring lubrication from the lubricant, a conduit between the lubricant tank and the first engine component and between the lubricant tank and the second engine component, a scheduling valve positioned in the conduit between the lubricant tank, and the first engine component and the second engine component, and a controller including a memory and a processor that controls the scheduling valve, wherein the memory includes an engine performance model, wherein the engine performance model includes stored relationship values between more than one condition experienced by the gas turbine engine during operation and a position of the scheduling valve, and wherein the scheduling valve varies a flow of the lubricant to the first engine component, the second engine component and the lubrication tank based on comparing the more than one condition with the engine performance model.

    Abstract: A method of controlling lubrication flow to a first engine component, a second engine component and a lubrication tank of a gas turbine engine according to an example of the present disclosure includes, among other things, determining more than one condition experienced by the gas turbine engine, comparing with a processor on a controller the more than one condition against an engine performance model stored in memory on the controller, wherein the engine performance model includes stored relationship values between the more than one condition and a position of a scheduling valve, the scheduling valve disposed between the lubricant tank and the first engine component and between the lubricant tank and the second engine component, pumping a lubricant from the lubricant tank through a conduit to the scheduling valve using a pump, and controlling the position of the scheduling valve to vary a flow of the lubricant to two or more of the first engine component, the second engine component and the lubrication tank based upon the comparing of the more than one condition experienced by the gas turbine engine.
