A power addition will require which combination of rudder trim and elevator trim?

• A. Left; up
• B. Right; down
• C. Left; down
• D. Right; up

Answer: (B)

The correct combination of rudder trim and elevator trim when performing a power addition is right rudder trim and down elevator trim. When power is added to an aircraft, it tends to yaw to the left due to the propeller's torque, especially in single-engine aircraft. To counteract this yaw to the left, the pilot needs to add right rudder trim. This adjustment helps keep the aircraft flying straight and balanced in response to the additional thrust. Additionally, adding power can also result in a tendency for the aircraft to pitch nose-up due to increased lift from the wings. To manage this pitch change effectively, the pilot would apply down elevator trim. This helps maintain level flight and ensures a smooth handling experience during the power addition. Thus, the specific combination of right rudder trim and down elevator trim is essential for maintaining stable flight characteristics as power is increased.
