Which control is used to change heading in a helicopter when in a no wind condition?

In a helicopter, when adjusting the heading in a no wind condition, the cyclic control is the primary means of achieving this maneuver. The cyclic control alters the pitch and roll of the helicopter by tilting the rotor disk, allowing the pilot to change the helicopter's direction effectively. By tilting the cyclic control forward, backward, or to the sides, the pilot can control the helicopter's lateral movement, enabling it to turn and face the desired heading.

In a no wind condition, making heading adjustments relies heavily on the pilot's input on the cyclic, as there are no external wind forces to influence the aircraft's path. This direct interaction with the cyclic allows for responsive and precise control, essential for maintaining stability and orientation during flight.
