Which primary flight control is used to initiate roll?

Explanation:
Initiating roll is done by the ailerons. When you move the control toward one wing, the ailerons deflect in opposite directions: one wing’s aileron goes up and the other goes down. The wing with the up-deflected aileron loses lift, while the wing with the down-deflected aileron gains lift. This lift difference tilts the aircraft about its longitudinal axis, starting a roll toward the lowered wing. The elevator affects pitch (nose up or down), the rudder affects yaw (nose left or right) and is mainly for coordination, not initiating roll. Trim is used to hold the surface in a neutral or desired position to reduce control forces, not to start the roll.
