Question: 1 / 400

Which component helps in controlling the pitch of helicopter blades?

The cyclic control

The collective control

The component that controls the pitch of helicopter blades, particularly in relation to managing lift, is the collective control. The collective control system allows the pilot to simultaneously adjust the pitch angle of all main rotor blades through a one-piece lever mechanism. When the pilot raises the collective, the pitch of the blades increases, creating more lift and allowing the helicopter to ascend. Conversely, lowering the collective decreases the pitch, reducing lift and enabling descent.

While other components like the cyclic control are important for adjusting the tilt of the rotor and controlling directional flight, the primary function of the collective is to manage the overall lift generated by the rotor blades by changing their pitch in unison.
