Identify the key control surfaces of the TH-73A.

• A. Flaps, spoilers, and slats
• B. Ailerons, elevators, rudder, and stabilator
• C. Ailerons, flaps, and rudder
• D. Rudder, stabilizer, and landing gear

Answer: (B)

The key control surfaces of the TH-73A include ailerons, elevators, rudder, and stabilator. These surfaces play a crucial role in the aircraft's ability to maneuver and maintain control during flight.

Ailerons are found on the wings and are responsible for controlling the roll of the aircraft. By moving in opposite directions, they help the pilot to bank the aircraft left or right. Elevators are located on the tail and control the pitch of the aircraft, allowing it to climb or descend. The rudder is also situated on the tail and is essential for controlling yaw, enabling the pilot to turn the aircraft left or right around its vertical axis.

The stabilator combines the functions of both the elevator and horizontal stabilizer, enhancing the aircraft's responsiveness and reducing drag. The design of the TH-73A incorporates these key surfaces to ensure effective aerodynamic performance and stability in various flight conditions.

In contrast, flaps, spoilers, and slats, while important for enhancing the lift and controlling airspeed during different phases of flight, are not classified as primary control surfaces. They serve different functions related to performance enhancement rather than direct control. The landing gear, on the other hand, is essential for takeoff and landing but does not influence
