TRUE/FALSE: During a Level 3 FADEC Failure, fuel flow on the affected engine will be frozen at its present value.

TRUE/FALSE: During a Level 3 FADEC Failure, fuel flow on the affected engine will be frozen at its present value.

• A. TRUE
• B. FALSE
• C. UNKNOWN
• D. CANNOT DETERMINE

Answer: (A)

In a Level 3 FADEC fault, the engine control system goes into a protective mode to keep the engine from reacting unpredictably to a severe failure. Locking fuel flow at its present value prevents any sudden or unexpected changes in fuel delivery that could lead to overspeed, flameout, or surge while the FADEC is unable to compute proper metering. This gives the crew a stable, known condition to manage with other procedures. That’s why the statement is correct: the fuel flow on the affected engine is frozen at the current value under this fault level. If the FADEC cannot reliably control fueling, maintaining the last commanded flow helps preserve controllability and safety until the situation can be addressed.
