What caution is shown on the EICAS page for a Level 1 FADEC failure?

• A. GOV LVL 1
• B. GOV LVL 2
• C. NONREDUNDANT
• D. FADEC FAIL

Answer: (A)

The test is about how EICAS signals FADEC faults with specific severity. When a Level 1 FADEC fault occurs, the EICAS displays GOV LVL 1 to indicate the engine governor control is degraded to level 1. This wording tells you exactly which subsystem is affected and the severity: the governor is still operating but with reduced authority, so you should monitor engine and rotor parameters and be prepared for degraded control or a progression to a more severe fault if conditions worsen. The other indications would correspond to different situations: a higher-severity governor fault would be GOV LVL 2; NONREDUNDANT points to a loss of redundancy in the FADEC system rather than a governor-degradation level; FADEC FAIL is a broader fault indication, not the specific Level 1 governor degradation shown by GOV LVL 1.
