Helicopter lateral control is obtained by...

  • A

    The tail rotor pitch control.

  • B

    The aerodynamic shape of fin.

  • C

    The pedals.

  • D

    The cyclic pitch control.

Refer to figure.
The three basic controls of helicopters are:

  • Cyclic control
  • Collective control
  • Tail rotor control

Cyclic control is the primary control used to change the direction of flight in a helicopter by altering the pitch of the main rotor blades at different points around the rotor disk. Typically located on the pilot's stick or joystick, it works in coordination with the collective control to change the helicopter's direction and altitude. Therefore, the cyclic pitch control is used for lateral control of the helicopter.

Collective control is used to change the altitude of the helicopter by adjusting the pitch of all of the main rotor blades at the same time, typically located on the pilot's left-hand side. It works in coordination with the cyclic control to control the helicopter's altitude and direction of flight, and also used to control the power of the engine by increasing or decreasing the collective.

Pedal control also called tail rotor control, is used to control the yaw or rotation of the helicopter by adjusting the pitch of the tail rotor blades, located at the tail end of the helicopter, which counteracts the torque effect of the main rotor. The pedals are located at the pilot's feet and are used to keep the helicopter pointed in the desired direction.
