What occurs when torque is present during flight?

When torque is present during flight, the aircraft rotates in the opposite direction of the propeller. This phenomenon is a result of Newton's third law of motion, which states that every action has an equal and opposite reaction. When the propeller spins in one direction, the force generated creates an equal and opposite reaction that causes the aircraft to rotate in the opposite direction.

This effect is particularly noticeable in single-engine aircraft where the propeller is mounted on the front. As the propeller rotates clockwise (for example), the aircraft will tend to roll or yaw to the left. Pilots must be aware of this tendency and use the aircraft's controls to counteract the effect during takeoff, climb, and other phases of flight, particularly when power settings are high. This understanding of torque is essential for safe operation and handling of the aircraft.
