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.

Touching down with the aircraft’s longitudinal axis aligned with the runway. We use the rudder to align the aircraft’s longitudinal axis with the centerline. Use the rudder to align the aircraft’s longitudinal axis with the runway centerline. We call this de-crabbing.
