Utility Helicopter 60M (UH-60M) Exam 2 Practice

The Lockout Procedure for the ENG POWER CONT lever is about establishing and holding a known rotor speed reference by pre-setting and locking the engine power levers to a specific position so the rotor speed remains at the desired percent RPM R. This gives a controlled, predictable spool and lets you monitor NR and engine parameters during start and checks without unintended lever movement.

It’s not a start-by-itself action, not a bypass of the main transmission, and not a command to drop rotor speed to a fixed 50%—the purpose is to command and maintain a specific rotor speed reference.
