What should you ensure regarding the PCL during an airstart?

• A. PCL is in maximum position
• B. PCL is in off position
• C. PCL is in idle position
• D. PCL is in travel position

Answer: (B)

During an airstart, it is essential to set the Power Control Lever (PCL) to the off position initially. This ensures that the engine starts without any excessive thrust which could damage components or lead to an unsafe condition during the critical phase of starting. By keeping the PCL in the off position, it allows for a controlled restart of the engine without introducing unnecessary power before the engine is stabilized and running properly. Once the engine has started and is stable, the PCL can then be gradually moved to the desired position for appropriate thrust management.

Setting the PCL to other positions, such as maximum or idle, could result in an abrupt surge of power that can complicate the starting process, and possibly lead to engine failure or additional complications. Thus, starting with the PCL in the off position is a fundamental procedural step for a safe and effective airstart.
