What is the purpose of the elevator located on the trailing edge of the horizontal stabilizer?

The elevator located on the trailing edge of the horizontal stabilizer plays a crucial role in controlling the pitch of the aircraft, which directly affects the nose's movement. When the pilot adjusts the elevator position, it changes the airflow over the stabilizer, allowing the aircraft's nose to move up or down. This adjustment enables the aircraft to ascend or descend according to the pilot's commands.

By manipulating the elevators, pilots maintain level flight or change altitude effectively, making it essential for overall flight control and stability. This function is vital during various phases of flight, including takeoff, climbing, cruising, and landing. Understanding the elevator's role in controlling pitch is fundamental for pilots and those studying aerodynamics.
