A propeller rotating clockwise, as seen from the rear, creates a spiraling slipstream that tends to rotate the aircraft to which direction?

The correct answer reflects the aerodynamic principles related to a propeller's rotation and the effects it has on an aircraft. When viewed from the rear, a clockwise-rotating propeller generates a spiraling slipstream that impacts the aircraft in distinct ways.

Firstly, the slipstream wraps around the fuselage and tends to push the tail to the left. This creates a yawing motion to the left around the vertical axis, which is generally associated with the aircraft's tendency to turn in the opposite direction of the propeller's rotation.

Secondly, the interaction of the rotating slipstream with the wings can lead to a differential lift across the wings. The wing that is closer to the rotating propeller experiences a slightly higher angle of attack compared to the opposite wing. Because the left wing (when the propeller rotates clockwise) experiences this increased effect, it can lead to a rolling motion to the right around the longitudinal axis.

Thus, the combination of these aerodynamic effects explains why the correct answer indicates a left yaw around the vertical axis and a right roll around the longitudinal axis, supporting a clear understanding of the behavior of the aircraft in response to a clockwise-rotating propeller.
