What reaction occurs when the nose of the aircraft is yawed left while using a clockwise turning propeller?

• A. If the nose is pitched up, a left yaw tends to develop
• B. If the nose is pitched down, a right yaw tends to develop
• C. If the nose is yawed left, the nose tends to pitch up
• D. If the nose is yawed to the right, the nose tends to pitch up

Answer: (C)

Yawing the nose of the aircraft to the left while using a clockwise turning propeller results in a differential in aerodynamic forces acting on the aircraft. This is largely due to the effects of torque, P-factor, and gyroscopic precession. When the nose is yawed left, the left side of the aircraft's wings is being pulled down more effectively due to the airflow changes around the wing, which creates increased lift on that side. This differential lift can cause an increase in the angle of attack on the left wing, and as a response to this imbalance, the aircraft tends to pitch up. In this context, the attitude of the aircraft is influenced by how the control surfaces are affected by the yawing motion combined with the rotational dynamics of the propeller. Understanding this concept is crucial for pilots since manipulating the aircraft's controls in the presence of yaw and the associated effects will significantly impact the aircraft's performance and handling characteristics.
