Level _____, or major FADEC failure is indicated on the EICAS page with a FADEC1/FADEC2 FAIL caution along with illumination of the red engine status light.

• A. LEVEL 1
• B. LEVEL 2
• C. LEVEL 3
• D. LEVEL 4

Answer: (C)

When a FADEC fault is shown as FADEC1/FADEC2 FAIL on the EICAS page together with the red engine status light, it signals a major FADEC failure. The FADEC system governs engine control, and having both FADEC channels report a fault along with the red engine light indicates a severe loss of engine control authority. In this rating scheme, that combination corresponds to Level 3, which is more serious than the amber cautions of Levels 1 and 2 but not the most extreme Level 4 scenario. So the presence of the red light plus the dual FADEC fail indication places the condition squarely in the major fault category, i.e., Level 3.
