Ice accumulation can cause what kind of control problem?

• A. Adverse roll control problems
• B. Enhanced roll stability
• C. Reduced yaw
• D. Increased maneuverability

Answer: (A)

Ice on the wings changes the airfoil shape and surface texture, which alters lift and increases drag where the ice is. This disruption makes lift distribute unevenly across the wing, so when you try to roll, one wing may generate more or less lift (and drag) than the other. The result is unpredictable rolling moments and reduced effectiveness of the ailerons, often leading to tricky or even dangerous roll behavior. That’s why ice accumulation is described as causing adverse roll control problems. The other options don’t fit because ice generally degrades stability and controllability rather than improving them, and increased maneuverability is not a consequence of icing.
