AFOQT Practice Test

The horizontal tail structure of an aircraft consists of which components?

1. Vertical stabilizer and rudder

2. Ailerons and elevators

3. Horizontal stabilizer and elevators

4. Flaps and leading edge devices

The correct answer is: Horizontal stabilizer and elevators

The horizontal tail structure of an aircraft primarily consists of the horizontal stabilizer and elevators. The horizontal stabilizer is a fixed structure that provides stability in the pitch axis, while the elevators are movable control surfaces attached to the trailing edge of the stabilizer. Together, they work to manage the aircraft's pitch and maintain level flight. The other components listed do not belong to the horizontal tail structure. For instance, the vertical stabilizer and rudder are part of the vertical tail structure, and ailerons are located on the wings. Flaps and leading-edge devices pertain to wing configurations designed to enhance lift during takeoff and landing, further differentiating them from the horizontal tail's functions.
