Airbus 320-200 rear horizontal trim control

Most airliners feature a large, slow-moving trimmable tail plane which is combined with independently-moving elevators. The elevators are controlled by the pilot or autopilot and primarily serve to change the aircraft's attitude, while the whole assembly is used to trim (maintaining horizontal static equilibrium) and stabilize the aircraft in the pitch axis, the angle in degrees marked. Hope it works today as I’m flying on it
