What does the EEC redline overspeed protection do to engine speeds?

• A. It limits maximum engine rotational speeds
• B. It limits minimum idle speed
• C. It reduces oil pressure
• D. It triggers reverse thrust

Answer: (A)

Overspeed protection is a safety feature that keeps engine speed from exceeding safe limits. The redline is the maximum permissible RPM, and the EEC monitors the engine speed and acts as a limiter if the speed approaches or passes that limit. It typically reduces fuel flow or otherwise trims the fuel schedule to stop the speed from climbing higher, pulling it back to a safe value. This function is not about idle speed, oil pressure, or reverse thrust. Idle control governs low-speed operation, oil pressure is a separate parameter, and reverse thrust is a thrust control action—not part of the overspeed limiter.
