When pushing left pedal, tail rotor thrust is increased, causing which nose motion?

• A. Nose up
• B. Increases tail rotor thrust, causing the nose to turn left
• C. Decreases tail rotor thrust
• D. No change

Answer: (B)

Yaw control with pedals uses tail rotor thrust to rotate the helicopter about its vertical axis. Pushing left pedal increases tail rotor thrust in a direction that creates a yawing moment toward the left, so the nose turns left. This is how the helicopter changes its heading without changing its pitch or roll.
