Question: 1 / 1030

Movement about the longitudinal axis (roll) in a helicopter is effected by movement of the

Collective pitch control

Cyclic pitch control

In a helicopter, the roll movement is controlled by the cyclic pitch control. The cyclic pitch control allows for the main rotor blades to have different pitches at different points in their rotation, which creates more lift on one side of the helicopter than the other, causing it to roll.

Option A, collective pitch control, is responsible for controlling the angle of attack for all of the main rotor blades at the same time and is used primarily for controlling the helicopter's vertical movement.

Option C, tail rotor control, is responsible for counteracting the torque produced by the main rotor in order to keep the helicopter from spinning in the opposite direction.

Option D, throttle, is used to control the engine power and affects a helicopter's altitude and forward or backward movement, but not its roll.
