What is the immediate consequence of moving the PCL to cutoff during ground operations?

When the Power Control Lever (PCL) is moved to the cutoff position during ground operations, the immediate consequence is that fuel flow to the engine is stopped, but the engine itself may not shut down instantly. However, one of the critical aspects to consider is that this action can lead to potential engine damage, especially if done improperly or without the necessary precautions. The fuel cut-off can create an abrupt change in engine speeds and temperatures, which are not advisable during operations on the ground where engine parameters should be controlled and stable.

In a situation where the PCL is moved to cutoff suddenly, it can also cause excessive stress or mechanical wear on engine components. Therefore, the option about potential engine damage reflects an important operational safety consideration that pilots need to be aware of when managing engine controls during ground operations.
