Which control surface is used to move the airplane's nose left and right?

The control surface responsible for moving the airplane's nose left and right is the rudder. The rudder is a vertical stabilizer located at the tail of the aircraft and is primarily used to control yaw, which is the left or right movement of the airplane's nose around its vertical axis. When the pilot applies pressure on the rudder pedals, the rudder moves in the direction the pilot intends, allowing for coordinated turns and helping maintain straight flight by counteracting adverse yaw caused by the ailerons during turns.

The ailerons, located on the wings, control roll rather than yaw. The elevator, located on the horizontal stabilizer, is responsible for controlling pitch, moving the nose up or down. Trim tabs are used to fine-tune the aircraft control surfaces, making it easier for the pilot to maintain control without constant pressure on the control inputs, but they do not directly control the movement of the nose left and right.
