What is the primary function of the foot pedals in a helicopter cockpit?

The primary function of the foot pedals in a helicopter cockpit is to control the torque effect. Helicopters utilize a main rotor system to generate lift, and as the rotors spin, they create equal and opposite torque on the airframe. To counteract this torque, pilots use the foot pedals to adjust the angle of the tail rotor blades, which helps maintain control and stability during flight. By adjusting the tail rotor's thrust, pilots can ensure that the helicopter remains oriented correctly and does not spin uncontrollably. The ability to manipulate this torque effect is essential for effective maneuverability in all phases of flight, making the foot pedals critical for pilot control and safety.
