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.
Claims19
A method of operation, comprising:
- operating a first power system of an aircraft powerplant to direct a first quantity of fuel into a flowpath of the aircraft powerplant for combustion;
- and
- testing a second power system of the aircraft powerplant during the operating of the first power system, the testing of the second power system comprising
- 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.
A method of operation, comprising:
- directing a first quantity of fuel into a flowpath of an aircraft powerplant for combustion using a first fuel system of the aircraft powerplant;
- and
- testing a second fuel system of the aircraft powerplant during the directing of the first quantity of fuel using the first fuel system, the second fuel system independent of the first fuel system, and the testing of the second fuel system comprising
- signaling the second fuel system to direct a second quantity of fuel into the flowpath for combustion;
- and
- monitoring operation of the aircraft powerplant following the signaling to evaluate operability of the second fuel system.
