A Level _____ FADEC (redundancy failure) can be accessed by selecting the Engine Faults page on the CDU.

• A. LEVEL 2 FADEC FAILURE
• B. LEVEL 1 FADEC FAILURE (Redundancy failure)
• C. LEVEL 3 FADEC FAILURE
• D. LEVEL 0 FADEC FAILURE

Answer: (B)

FADEC fault levels are used to categorize engine control faults on the CDU. A FADEC redundancy failure is specifically labeled as Level 1, meaning it’s a fault in the FADEC’s redundant channel system that the cockpit can monitor and review on the Engine Faults page without implying a complete engine shutdown. The Engine Faults page is the right place to see this redundancy-related fault, which is less severe than higher-level FADEC faults. Higher levels (and Level 0) represent either no fault or more severe conditions that would typically require different diagnostics or maintenance actions.
