Which factors typically induce a Dutch Roll motion?

Dutch Roll is a specific type of oscillatory motion characterized by a combination of lateral yaw and roll, commonly experienced in certain types of aircraft. The phenomenon arises primarily due to the aircraft's lateral stability and the response to directional control inputs.

When considering the correct answer, rough air or lateral directional control inputs are significant contributors to inducing a Dutch Roll motion. In turbulent conditions, the aircraft suffers from sudden and varying gusts that can disrupt its stability and induce a roll or yaw. Additionally, when pilots make lateral control inputs, such as with the ailerons or rudder, it can provoke an oscillatory reaction leading to a Dutch Roll.

This type of motion typically occurs in aircraft designs that favor stability in one direction over another, thus making them more prone to variations in yaw and roll during these conditions. Understanding the dynamics of how the aircraft reacts to external turbulence or pilot inputs is crucial for managing and mitigating the Dutch Roll tendency during flight.
