In forward flight, yaw is most significantly affected by:

• A. Bank angle
• B. Airspeed
• C. Tail rotor thrust
• D. Elevator position

Answer: (C)

Yaw in forward flight is driven mainly by the tail rotor thrust, which provides the anti-torque that counteracts the torque created by the main rotor. When you apply pedal, you change how much thrust the tail rotor produces, creating a yawing moment that turns the helicopter to the left or right. Bank angle influences the turning rate by tilting the lift vector, but it does not generate yaw torque by itself. Elevator position affects pitch, not yaw. Airspeed can change how effectively the tail rotor works, but the direct cause of yaw is the tail rotor thrust control.
