What term describes tilting the rotor disc to produce horizontal movement by adjusting cyclic pitch?

• A. Cyclic Pitch Control
• B. Cyclic Feathering
• C. Delta Hinge
• D. Density Altitude

Answer: (A)

Tilting the rotor disc to produce horizontal movement is accomplished with the cyclic pitch control. The cyclic changes the pitch of each rotor blade as it rotates, creating more lift on one side of the disc than the other. Thatunequal lift tilts the rotor plane in the desired direction. Pushing the cyclic forward increases lift at the front of the disk and reduces it at the rear, tilting the disc forward and producing a forward thrust component. Pulling back tilts the disc backward for reverse movement, while a sideways input tilts it left or right for lateral movement. The helicopter still needs to maintain vertical lift, so the collective is adjusted separately to hold altitude. This control differs from collective pitch, which changes the pitch of all blades equally to climb or descend, and from rotor-head terms like delta hinge or from environmental terms like density altitude.
