Which control surface is used for pitch adjustments?

The elevator is the control surface specifically designed for making pitch adjustments in an aircraft. When the pilot pulls back on the yoke or control stick, the elevators move upwards, which causes the tail of the aircraft to move downwards, resulting in the nose of the aircraft raising and the aircraft climbing. Conversely, when the pilot pushes forward, the elevators move downwards, lowering the tail and causing the nose to drop, leading to a descent.

The functionality of the elevator is essential for managing the aircraft's angle of attack and controlling altitude during flight, making it the primary control surface for pitch. Other control surfaces such as the rudder, ailerons, and flaps serve different purposes, focusing on aspects such as directional control, roll stability, and lift enhancement, respectively, but do not directly influence pitch.
