What is the primary function of the elevator on an aircraft?

The primary function of the elevator on an aircraft is to control pitch and maintain altitude. The elevator is located on the horizontal stabilizer at the tail of the aircraft and works by altering the aerodynamic profile of the tail surface. When the elevator is deflected upward, it generates a downward force on the tail, causing the nose of the aircraft to pitch up. Conversely, if the elevator is pushed down, it results in an upward force on the tail, causing the nose to pitch down.

This function allows the pilot to control the angle of attack of the aircraft, which is critical for climbing, descending, or level flight. Maintaining appropriate pitch is essential for stabilizing an aircraft during various phases of flight, including takeoff, landing, and cruising. By effectively managing the aircraft's pitch with the elevator, the pilot can ensure safe and efficient flight operations.
