What happens to the power control lever (PCL) once set in cruise?

• A. It increases automatically
• B. It decreases automatically
• C. It remains unchanged
• D. It must be manually adjusted

Answer: (C)

When the power control lever (PCL) is set in cruise, it is designed to maintain a stable engine performance appropriate for cruising conditions. Once set, the PCL will hold its position unless manually adjusted. This allows for a consistent power output that is necessary for sustained flight at cruising altitude, reducing the need for constant pilot adjustments and optimizing performance in a fuel-efficient manner. While there may be scenarios requiring adjustments due to changing flight conditions or power requirements, the primary function of the PCL in cruise is to remain unchanged, ensuring smooth and efficient operation. This is essential for flight stability and minimizes pilot workload during cruise flight.
