Which component of the empennage is responsible for managing left and right movement of the aircraft?

The component of the empennage that manages the left and right movement of the aircraft is the rudder. The rudder is a vertical control surface located on the vertical stabilizer at the tail of the aircraft. It primarily controls the yaw movement, which is the rotation of the aircraft around its vertical axis. By deflecting the rudder to one side, the pilot can create a differential thrust that causes the aircraft to rotate left or right.

While the elevator, ailerons, and vertical stabilizer play important roles in flight control, they function differently. The elevator is responsible for managing pitch, or the up-and-down movement of the aircraft's nose. Ailerons control roll, which tilts the aircraft to the left or right. The vertical stabilizer, while it provides stability and houses the rudder, does not itself control movement but rather aids in maintaining directional stability.
