An aircraft, controller, and method for simultaneously using a liquid fuel and a gaseous fuel. The use of natural gas and other similar fuels in gas turbines engines can enable an aircraft to operate less expensively. However, aircraft often use liquid fuels en route to the gas turbine engine burners for secondary purposes, such as oil cooling and hydraulic pressure. The aircraft, controllers, and methods described herein feed a minimal quantity of liquid fuel to an engine to satisfy the secondary purposes while simultaneously feeding a quantity of gaseous fuel to the engine to satisfy a thrust command for the engine.
