Which Emergency Procedure is invoked when any engine data fault such as oil pressure or oil temperature fails to function?

• A. ENGINE INDICATING SYSTEM FAILURE
• B. ENG OIL P
• C. FADEC FAIL
• D. GOV LVL 2

Answer: (A)

When engine data sources stop functioning, the crew must rely on the procedure that covers a loss or failure of the engine indicating system itself. This scenario isn’t about a single parameter like oil pressure or oil temperature failing, but about the data stream that feeds the engine indicators becoming unavailable. The Engine Indicating System Failure procedure is designed for exactly that situation: it prepares you to fly with degraded engine data, use any available standby indicators if present, and follow steps to maintain safe operation while continuing to monitor the aircraft. The other options target a fault in one parameter, a specific subsystem like FADEC, or a governor level issue, none of which address a general failure of the engine indicating data stream.
