What is the role of the anti-torque pedals in a helicopter?

The role of the anti-torque pedals in a helicopter is to counteract the torque effect of the main rotor. When the rotor blade turns in one direction, it creates a rotational force that tries to turn the helicopter's fuselage in the opposite direction, a phenomenon known as torque effect. To maintain directional control and stabilize the helicopter, the pilot uses the anti-torque pedals, which control the pitch of the tail rotor blades. By increasing or decreasing the pitch of the tail rotor, the pedals provide the necessary thrust to counterbalance the torque generated by the main rotor, thus preventing unwanted yawing motion.

The other options are not related to the function of anti-torque pedals. Raising landing gear pertains to ground operations, controlling pitch of rotor blades is generally managed by the cyclic control, and adjusting the throttle relates to engine power management but does not directly involve anti-torque pedals. Understanding the primary function of the anti-torque pedals is essential for pilots to ensure effective handling and stability of the helicopter in flight.
