What connects the PCL to the FMU?

• A. A flexible cable
• B. Hydraulic lines
• C. A solid rod
• D. Electrical wiring

Answer: (A)

The correct choice indicates that a flexible cable connects the Power Control Lever (PCL) to the Fuel Management Unit (FMU). This flexible cable is designed to transmit mechanical inputs from the PCL to the FMU, allowing for precise control over fuel flow to the engine based on the pilot's throttle input. The use of a flexible cable is essential because it accommodates the dynamic movements and positioning of the PCL while ensuring reliable transmission of the pilot's commands.

In the context of this question, the function of this cable is crucial to the operation of the aircraft, as it directly influences engine performance and response to throttle adjustments. A flexible cable effectively maintains the necessary connection while providing the required freedom of movement needed in the cockpit.
