What component provides stabilization for the yaw control of the helicopter?

• A. Tail rotor
• B. Anti-torque pedals
• C. Main rotor
• D. Collective control

Answer: (A)

The tail rotor is critical in providing stabilization for yaw control in helicopters. Yaw refers to the rotation of the helicopter around its vertical axis, which is necessary for maneuverability and directional control during flight. In a single-rotor helicopter design, the main rotor generates a torque that tends to make the helicopter spin in the opposite direction. To counteract this torque and maintain stable flight, the tail rotor provides a sideways thrust that helps balance the rotational forces. The tail rotor's effectiveness in controlling yaw allows the pilot to make precise adjustments to the helicopter's heading, which is essential for both stabilizing flight and executing turns. As the pilot applies inputs through the anti-torque pedals, the tail rotor adjusts its pitch to increase or decrease thrust, thereby controlling yaw effectively. While anti-torque pedals allow the pilot to control the pitch and thrust of the tail rotor, it is ultimately the tail rotor itself that generates the necessary force for stabilization. The main rotor and collective control, while crucial for lift and altitude management, do not directly influence yaw stability in the same way that the tail rotor does.
