How does a fixed-wing aircraft differently induce yaw compared to a multirotor aircraft?

• A. By reducing thrust on the main engines
• B. A fixed-wing moves a rudder into the airstream, whereas a multirotor increases the RPM of two diagonal motors
• C. By adjusting the angle of the wings
• D. By changing the center of gravity

Answer: (B)

A fixed-wing aircraft induces yaw primarily through the use of its rudder, which deflects into the airstream and creates a differential in airflow on either side of the vertical stabilizer. This difference in airflow causes the aircraft to rotate about its vertical axis, resulting in a yaw motion. The effective operation of the rudder is essential for coordinated flight and helps manage the aircraft’s directional control, particularly during turns. In contrast, multirotor aircraft, which utilize multiple rotors for lift and control, induce yaw through a different mechanism. To achieve a yaw motion, a multirotor increases the rotational speed of two diagonally opposite motors. By doing so, it generates a differential thrust that pushes one side of the aircraft more than the other, allowing it to rotate around its vertical axis. This method provides a rapid and responsive means of controlling yaw, which is crucial for maintaining stability and directional control during flight. Understanding these differences is vital for operators, as it informs how each type of aircraft handles directional changes and assists in effective flight control.
