<p>A gas turbine engine control apparatus comprises a controller (34), a memory (36) associated with the controller (34) and inputs (38) for measurement data from an engine. The controller (34) determines the start of a monitoring cycle at (73), receives measurement data at the inputs (38) during the monitoring cycle, manipulates the measurement data to provide an incremental deterioration value representing deterioration occurring within the engine and during the monitoring cycle, and uses the incremental deterioration value at (72) to update a deterioration value (74) stored in the memory (36), and determines the start of a further monitoring cycle.</p> |
