Abstract
An aircraft engine diagnostic system includes at least one sensor and a diagnostic controller. The at least one sensor measures a parameter of a gas turbine engine. The diagnostic controller is in signal communication with the at least one sensor. The diagnostic controller determines an actual thrust output of the gas turbine engine and an execution of at least one control system limiter configured to limit control of the gas turbine engine based on the measured parameter. The diagnostic controller further determines an existence of an engine fault based on the actual thrust output of the gas turbine engine and an execution of the at least one control system limiter.
