Methods and systems for operating an aircraft engine. A health parameter for the engine received from a first instrument is monitored by a health evaluation device communicatively coupled to a communication link between an engine controller and a second instrument which generates an operation parameter signal indicative of an engine operating condition. The health parameter is compared, by the health evaluation device, to a predetermined threshold. When the health parameter is below the threshold, the health evaluation device causes the operation parameter signal to be transmitted from the second instrument to the controller. When the health parameter reaches the threshold, the health evaluation device prevents the operation parameter signal from being transmitted from the second instrument to the controller, and transmits to the controller a fault signal to elicit a health response therefrom, the fault signal containing at least two mutually-exclusive fault codes associated with the operating condition.
