Windmilling Propeller Limitation: Do not allow the engine to turn at less than ___ NG for greater than ___ , or greater than ___ NG for
___ with a propeller feathered (propeller is visibly rotating at less than one half revolution per second) with

Q

Autopilot Limitations:

A

Do not operate with the autopilot engaged during the following situations:
