What is the role of the cyclic control in a helicopter?

The cyclic control plays a crucial role in helicopter flight by altering the pitch of the rotor blades as they rotate. It allows the pilot to change the angle of attack of the rotor blades at different points in the rotor's cycle, enabling the helicopter to tilt and maneuver in various directions. By adjusting the pitch, the cyclic control facilitates forward, backward, and lateral movements, which is essential for controlling the helicopter's direction and altitude effectively during flight. This function is fundamental to helicopter operation, allowing for precise control over movement in three-dimensional space, unlike fixed-wing aircraft.
