Which factor does NOT contribute to the aircraft's yawing tendency?

• A. The corkscrewing effect of the propeller slipstream
• B. Torque reaction to the engine and propeller
• C. The propeller's dynamic stability
• D. The asymmetrical landing of the propeller (P factor)

Answer: (C)

The propeller's dynamic stability does not contribute to the aircraft's yawing tendency. Dynamic stability refers to the way an aircraft responds to disturbances over time and is concerned with the overall stability characteristics of the aircraft in flight. While propeller dynamics play a significant role in thrust and performance, the stability aspects do not directly influence the yawing motion induced by other factors. In contrast, factors like the corkscrewing effect of the propeller slipstream, torque reaction to the engine and propeller, and the asymmetrical landing of the propeller (P factor) all contribute to yaw. The slipstream effect creates a rotational movement affecting yaw, torque reaction creates a tendency to roll and yaw the aircraft, and P factor occurs due to unequal lift on the propeller blades during certain phases of flight. Therefore, the dynamic stability of the propeller does not create a yawing tendency in the same way these other factors do.
