When the pilot pushes the cyclic forward, the cyclic control inputs cause the rotor disk to tilt forward. This forward tilt directs the lift generated by the rotor disk forward, allowing the helicopter to move in that direction. This fundamental aspect of helicopter flight dynamics is crucial in controlling the helicopter's movement and response to pilot inputs.

While the other choices describe effects related to cyclic inputs, they aren't the primary direct consequence of pushing the cyclic forward. For example, pushing the cyclic forward does not inherently lead to a backward angle of attack on the tail rotor decreasing; rather, that would depend on various flight conditions and other control adjustments. Similarly, the specific effects on the driven portion's angle of attack also depend on more complex interactions within the rotor system. Therefore, while those may happen, they are not the defining and direct consequence of the cyclic input itself as tilting the rotor disk forward is.
