Which control surface is attached to the rear of the horizontal stabilizers and controls movement up and down?

Which control surface is attached to the rear of the horizontal stabilizers and controls movement up and down?

• A. Elevators
• B. Slats
• C. Wings
• D. Airfoil

Answer: (A)

Elevators control pitch, the motion that raises or lowers the aircraft’s nose. They are the hinged surfaces on the trailing edge of the horizontal stabilizers at the tail. When the elevator surfaces tilt, they change the tail’s lift and create a pitching moment that makes the nose go up or down. This is why they’re attached to the rear of the horizontal stabilizers and access nose-up or nose-down movement. Slats are on the wing leading edge to improve airflow at high angles of attack, not on the tail. Wings are the main lifting surfaces, not control surfaces on the tail. An airfoil is the shape of a wing or blade, not a movable surface.
