Which outcome directly affects an aircraft's control surfaces following icing that exceeds anti-ice system capacity?

💡 Explanation

When icing exceeds the anti-ice capacity, ice accretion modifies control surface profiles; the accumulated ice physically obstructs the proper movement because the actuators struggle to overcome the increased resistance. Therefore, restricted movement/maneuverability results, rather than altered lift,increased drag, or fuel consumption which involve different aeroelastic mechanisms arising from milder icing.
