Which indicator illuminates red along with FADEC1/FADEC2 FAIL during Level 3 FADEC failure?

• A. Engine Status Light
• B. Tail Rotor Light
• C. Master Caution
• D. Fuel Flow Warning

Answer: (A)

When a Level 3 FADEC failure occurs, you’re dealing with a critical engine condition that demands immediate action. The red Engine Status Light is the dedicated engine warning indicator that illuminates alongside FADEC1/FADEC2 FAIL to signal this severe condition. This combination gives you a clear, unambiguous cue that the engine control has failed and you must follow the FADEC failure procedure.

The Tail Rotor Light is associated with tail rotor issues, not FADEC faults, so it wouldn’t be the surrogate indicator for a FADEC failure. The Master Caution is a general alert that can come on for various faults and isn’t the specific red indicator that pairs with FADEC failure. The Fuel Flow Warning points to fuel flow problems, not directly to FADEC faults.
