Which component provides a means to change the pitch in the tail rotor blades?

• A. Tail Rotor Head
• B. Tail Rotor Blades
• C. Swashplate
• D. Pitch Control Rods

Answer: (D)

Pitch is changed in the tail rotor by the pitch control rods. These rods connect the tail rotor hub to the control system (pedals) and transmit movement to the blade roots, adjusting each blade’s angle to create the desired thrust for yaw control. The tail rotor head is the hub that mounts the blades and allows them to pivot, but it doesn’t generate the pitch change by itself. The tail rotor blades are the components whose angle is set, but they rely on the pitch control rods to move them. The swashplate is the device that translates pilot inputs into blade pitch changes for the main rotor; it isn’t what sets tail rotor pitch in this configuration.
