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.

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. This movement turns the aircraft about the longitudinal axis, making it enter a bank.

Helicopters use a small rotor mounted on the tail that produces sideways thrust to counter the main rotors torque reaction. The tail rotor pushes air to one side ( action ), and the tail moves the other way ( reaction ). Other Designs The tail rotor is not the only way to solve the torque reaction problem.

The left winglet of one of the aircraft collided with the right horizontal stabilizer and elevator of the other. The aircraft sustained damage to the leading edge of the right-hand horizontal stabilizer and was subsequently repaired. The tail of the aircraft struck the ground and impacted a fence before it got airborne.
