What occurs when a pilot pushes the control yoke forward?

Pushing the control yoke forward directly affects the aircraft's elevators, which are located on the tail section. When the pilot pushes the yoke forward, the elevators are commanded to lower. This action changes the airflow over the elevators, creating a downward force that causes the aircraft's nose to pitch down. As a result, the aircraft begins to descend or decrease its altitude unless other control inputs are made to counteract this movement.

Maintaining level flight or causing the aircraft to lift off would not occur with a forward push on the yoke; those actions typically require specific rotations or adjustments in thrust rather than a downward elevator movement. Similarly, activating the ailerons for a roll pertains to side-to-side motion and is not relevant to the forward push of the yoke, which specifically relates to pitch control.
