Ice accumulation on an aircraft can cause what kind of roll-related issue?

• A. Adverse roll control problems
• B. Enhanced roll stability
• C. No effect on roll
• D. Increased yaw stability

Answer: (A)

Ice accumulation on the wings disrupts the smooth airflow that normally lets the wing produce predictable lift and lets the ailerons work effectively. When ice forms unevenly, one wing can lose lift or balance differently than the other, causing an unexpected rolling motion. The ice also roughens the wing surface and adds weight, which further reduces control surface effectiveness and makes roll inputs less reliable. All of this can lead to adverse roll control problems, where the aircraft doesn’t respond to roll commands in the way you’d expect and may roll in the wrong direction or with reduced roll rate. The other options imply improved or unchanged roll behavior, which isn’t supported by how ice changes wing aerodynamics.
