What are the 4 positions of the PCL?

Explanation:
The PCL controls engine power and how the engine and governor behave, and its four positions define distinct operating modes. In the OFF position the engine is shut down, stopping fuel flow. In IDLE the engine runs at a low, idle speed to power essential systems and allow safe engine start. In FLY the engine is producing normal flight power with the governor actively regulating RPM for steady flight performance. In LOCKOUT the automatic governor is disengaged, effectively locking the lever so manual control is required, a mode used during certain maintenance or ground operations. This set of four positions—OFF, IDLE, FLY, LOCKOUT—is why that option is correct.
