Classification: CPC F | IPC F

Claim 7:
8. A method for determining an engine health factor of an aircraft engine, comprising:
determining, by an engine controller, an engine condition indicative of an engine health during operation of the aircraft engine, the engine condition comprising a measure of an amount of particulate matter detected in the aircraft engine during flight;
accessing, by the engine controller, a baseline engine power model simulating expected engine performance of a nominal aircraft engine with a nominal degradation;
modifying, by the engine controller, the baseline engine power model using the engine condition, wherein the baseline engine power model is modified responsive to the particulate matter to generate a modified engine power model; and
determining, by the engine controller, an engine health factor based on the modified engine power model and a maximum turbine temperature.
