What are the main components of a helicopter’s flight control system?

The main components of a helicopter's flight control system include the cyclic, collective, and anti-torque pedals. The cyclic control allows the pilot to tilt the rotor disc in any direction, which in turn affects the helicopter's forward, backward, or lateral movement. This control is essential for maneuvering the helicopter in three-dimensional space.

The collective control alters the pitch of the rotor blades simultaneously, allowing the helicopter to gain or lose altitude. By increasing the pitch, the blades generate more lift, assisting in climbing, while decreasing it facilitates descent.

The anti-torque pedals are used to manage the torque produced by the main rotor. As the rotor spins, it creates a counteracting force that would cause the helicopter to spin in the opposite direction due to Newton's third law. The anti-torque pedals counteract this effect by adjusting the pitch of the tail rotor blades, enabling the pilot to maintain directional control.

Understanding these components is crucial for a pilot because they directly influence the helicopter's performance and handling. They work together to provide comprehensive control over flight dynamics, unlike the other options that refer to instruments or components not directly related to flight control systems.
