AIRCRAFT GAS TURBINE ENGINE CONTROLLER WITH REMOVABLE MEMORY AND DIAGNOSTIC SYSTEM AND METHOD THEREFOR

A system and method of analyzing aircraft gas turbine engine performance data includes receiving, in an engine controller, engine performance data representative of a plurality of aircraft gas turbine engine parameters. At least a portion of the received engine performance data are stored in a fixed memory device that is fixedly coupled to a fixed-memory mount in the engine controller, and in a removable memory device that is non-fixedly coupled to a removable memory mount in the engine controller in a manner that allows the removable memory device to be hand-removable from the removable memory mount. The removable memory device is removed from the removable memory mount in the engine controller, and inserted in a port of a computing device that is not coupled to the engine controller.
