What is a Dutch Roll? The Aircraft Maneuver Every Pilot Should Know
In aviation, Dutch roll refers to a potentially dangerous flight instability where an aircraft experiences a combination of yaw and roll oscillations. It can either be a specific maneuver or a naturally occurring aircraft phenomenon. Definition and Dynamics of the Dutch Roll Dutch roll is an aircraft motion where the tail is wagged side to side (yaw) while the wings rock from side to side (roll), with both movements occurring out of phase. It is caused by aerodynamic coupling between the yaw (side-to-side motion) and roll (banking motion) axes of an aircraft. This is sometimes called yaw and roll coupling. When a jet or commercial airliner, like a Boeing 737 MAX, experiences this instability, it may begin to oscillate. These … Read more
