The use of the HIGH PWR SCHEDULE switch is not permitted for what?

The use of the HIGH PWR SCHEDULE switch is specifically not permitted for normal operations. This switch is designed to allow the aircraft to use a higher power setting for takeoffs and climb, which is essential in certain phases of flight. In normal operations, the aircraft is intended to operate efficiently, and using the HIGH PWR SCHEDULE switch would not align with the efficiency and performance profile expected during routine flight phases.

In contrast, during takeoffs and emergency procedures, the switch is utilized to provide increased power output to enhance performance and safety, particularly in critical situations where maximum thrust is required. Landings typically require lower power settings, which is viable without activating the HIGH PWR SCHEDULE switch. Thus, its restriction to normal operations ensures that pilots operate within the aircraft's prescribed parameters for performance and safety.
