Which statement best describes a function of the engine control system?

• A. To keep the rotor speed constant under all operations.
• B. To allow manual control of the fuel flow for starting, and in case of fuel control failure.
• C. To monitor hydraulic pressure and trigger fault indication.
• D. To coordinate engine shutdown procedures in abnormal conditions.

Answer: (D)

The engine control system is designed to protect the engine and ensure safe operation by responding to abnormal conditions. When sensors detect parameters outside safe limits (such as low oil pressure, high temperature, loss of fuel, or overspeed), the control system automatically initiates a coordinated shutdown sequence. This means it trims or cuts off fuel, closes valves, and triggers alarms in a controlled way to bring the engine to a safe stop and prevent damage or hazardous situations. While speed regulation and fault indication are part of the overall management of a running engine, the primary role highlighted here is the automated, coordinated shutdown under abnormal conditions to safeguard the equipment.
