The function of the elevator on a Cessna 172 is to control the pitch of the aircraft by moving the nose up or down around the lateral axis. The elevator is attached to the trailing edge of the horizontal stabilizer. The elevator changes its angle of attack, affecting the lift and balance of the aircraft. The elevator deflection mechanism controls the elevator’s movement via movement of the yoke in the cockpit. Pulling back on the yoke raises the nose, and pushing forward on the yoke lowers the nose. Elevator trim fine-tunes the elevator position for stable cruising.

The elevator deflection mechanism operates through inputs from the yoke, which are transmitted via a cable and pulley system. This system connects the control yoke to the elevator control surface, enabling precise adjustments in pitch attitude. The elevator alters the aircraft's pitch by adjusting its angle of attack, directly influencing the aerodynamic forces acting on the horizontal stabilizer. The Cessna 172 aircraft control system integrates the elevator with the horizontal stabilizer to maintain stability during flight. Horizontal stabilizer stability augmentation ensures balanced flight by preventing excessive pitching moments caused by varying airspeed or load distribution.

Horizontal stabilizer trim function fine-tunes the elevator position for stable cruising. Pilots adjust pitch attitude using the trim wheel, which moves the elevator trim tab to counteract control forces. This adjustment allows pilots to maintain a consistent pitch attitude without continuous input, reducing workload during flight. Elevator pitch control effectiveness depends on airspeed, elevator area, and deflection angles. Typical elevator deflection ranges for the Cessna 172 measure 20° upward and 15° downward, delivering robust mechanical and aerodynamic regulation.

Flight control surface aerodynamic regulation relies on the elevator's ability to alter airflow over the horizontal stabilizer. Upward deflection generates downward lift at the tail, raising the nose, while downward deflection creates upward lift, lowering the nose. The elevator's placement at the tail provides mechanical leverage, optimizing pitch control attitude adjustment. A typical elevator cable diameter measures about 0.25 inches (6.35 millimeters), running from the yoke through pulleys to the elevator control horn. The Cessna 172 achieves pitch trim exclusively through the elevator trim tab, as it lacks a horizontal stabilizer trim function.
