with differential ailerons to reduce adverse yaw in a turn.

rudder/stabilizer overload.

connected directly to the pilot's control and moves the control surface to which it is attached aerodynamically

make an aircraft oppose a constant disturbing force such as propeller slipstream.

right spoilers extending, left spoilers remaining retracted.

nose up moment on the aeroplane.

provide higher lift at low speed or roll control, or a combination of both.

after touchdown only.

helps to prevent spanwise flow of the airflow across the wing.
