Dutch roll is a coupled, oscillatory motion in an aircraft, combining both yaw (movement around the vertical axis) and roll (rotation around the longitudinal axis). It’s triggered by a disruption , like a gust of wind, impacting the aircraft’s stability. This initial yaw shifts one wing ahead of the other.

Adverse yaw is a side effect of aileron use, countered by rudder input. Roll or bank is the aircrafts movement about its longitudinal axis. Since theyre located on opposing sides of the longitudinal axis, both ailerons need to move in the opposite directions to complement each others motion. What Is an Aileron?

They allow roll control about the aircrafts longitudinal axis. Both forces complement each other, and the net torque about the longitudinal axis makes the aircraft roll. It offers pitch control, meaning the aircraft pivots about the lateral axis. Yaw means side-to-side movement about the vertical axis.
