Which component provides a constant resistance in the pedals to prevent over-control of the tail rotor?

• A. Pitch Change Link
• B. Hydraulic Pump
• C. Wiper
• D. Yaw Brake

Answer: (D)

The pedals’ feel is tuned to prevent over-control of the tail rotor by adding damping to pedal movement. The yaw brake provides a constant resistance (friction/damping) in the tail-rotor pedal system, so small or quick pedal inputs don’t translate into abrupt, large tail-rotor changes. This keeps yaw motions smooth and predictable, helping the pilot avoid overcorrecting. The other components have different roles: the pitch change link adjusts main rotor blade pitch, the hydraulic pump powers the hydraulic controls, and the wiper is unrelated.
