Is the PCL connected to the fuel management unit mechanically or electrically?

The primary characteristic of the Power Control Lever (PCL) in the T-6A is its connection to the fuel management unit, which is indeed both mechanical and electrical. The mechanical aspect allows the PCL to physically move in response to pilot input, directly affecting the fuel flow delivered to the engine. This is crucial for controlling the thrust and performance of the aircraft.

Simultaneously, the PCL is equipped with electrical components that provide feedback and enhance control capabilities. These electrical signals are sent to the engine control unit to monitor the position of the lever and ensure that the appropriate fuel settings are engaged. This dual connection allows for more precise management of the aircraft's fuel system, integrating both the pilot's mechanical adjustments and the electronic systems that optimize engine performance.

Understanding this dual functionality is essential for effective operation of the T-6A and highlights the complexity of modern aircraft systems where both mechanical and electrical components work together harmoniously.
