Abstract
A method of operation is provided. During this method, a first power system of an aircraft powerplant is operated to direct a first quantity of fuel into a flowpath of the aircraft powerplant for combustion. A second power system of the aircraft powerplant is tested during the operating of the first power system. The testing of the second power system includes: signaling the second power system to direct a second quantity of fuel into the flowpath for combustion; determining an operational parameter of the aircraft powerplant following the signaling; and evaluating operability of the second power system by comparing the operational parameter to a threshold.
