When takeoff power is set in Propeller Low Speed Mode, the RPM changes from which value to which value?

• A. From 1550 RPM to 1700 RPM
• B. From 1500 RPM to 1600 RPM
• C. From 1700 RPM to 1800 RPM
• D. No RPM change

Answer: (A)

In Propeller Low Speed Mode, the propeller is held at a lower baseline RPM (1550) to reduce loads during taxi and early phases. When you set takeoff power, the governor automatically raises the RPM to the takeoff target of 1700 to deliver the required thrust for liftoff. So the RPM changes from 1550 to 1700 as you apply takeoff power.
