Which of the following is considered a gyroscopic effect caused by a clockwise turning propeller?

The correct answer highlights the specific gyroscopic effect that occurs when a clockwise turning propeller is in play, particularly in relation to how the aircraft behaves when the nose is pitched up.

When a clockwise propeller spins, the gyroscopic precession principle states that when a force is applied to the rotor, the resulting effect will occur in the direction of the rotation 90 degrees later in the plane of rotation. So, if the nose of the aircraft is pitched up, the effect of the clockwise propeller results in a tendency for the aircraft to yaw to the right. This is because the force generated by the rotating propeller interacts with the airframe in such a way that it causes a yaw motion in that direction.

Understanding this principle is critical for pilots to anticipate and counteract the aircraft's response during maneuvers, particularly takeoff and climb phases, where changes in pitch can produce significant yaw dictated by the gyroscopic precession of the engine's propeller.
