What is the first step in the Motoring Run Procedures?

• A. PCL - OFF
• B. IGNITION switch - NORM
• C. Propeller area - Clear
• D. STARTER switch - MANUAL

Answer: (A)

The correct first step in the Motoring Run Procedures is to turn the Power Control Lever (PCL) to the OFF position. This action ensures that the fuel flow to the engine is stopped, allowing for a safe start to the engine motoring process. When the PCL is OFF, it minimizes the risk of engine ignition or any fuel-related incidents that could occur during the initial phases of the procedure.

Starting with the PCL in the OFF position lays the groundwork for verifying the status of the engine systems without the risk of unintended engine start. Thus, it is essential to begin the procedure in this manner, ensuring that safety protocols are adhered to effectively. This prioritization of safety is crucial, particularly in aviation operations where operational protocols manage risks associated with engine start-ups and system checks.
