Abstract
A method for controlling a fuel system for a gas turbine engine is disclosed. The method includes directing fuel from an outlet of a main pump to an inlet of a fuel oil cooler. Fuel is directed from an outlet of the fuel oil cooler to a fuel control. The fuel control is in fluidic communication with a burner of the gas turbine engine. Fuel is directed from the outlet of the main pump to the fuel control through a fuel-oil-cooler bypass valve whenever an augmentor pump of the fuel system is actively pumping fuel to an augmentor of the gas turbine engine. The fuel-oil-cooler bypass valve forms a bypass flow path around the fuel oil cooler.
