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

The function of foot pedals in a helicopter cockpit is primarily to control the torque effect, which is essential for maintaining proper flight stability. Helicopters operate on the principle that the main rotor generates lift, but as the rotor spins, it also creates a counter-clockwise torque effect that tends to rotate the helicopter’s fuselage in the opposite direction.

To counteract this torque, pilots use the foot pedals to control the tail rotor’s pitch, which adjusts its thrust. By properly modulating the tail rotor’s thrust, a pilot can maintain directional control and prevent unwanted yaw movements. Therefore, the foot pedals are integral in ensuring that the helicopter remains stable and on course during flight.
