Ice accumulation effects on flight control can include which of the following?

• A. Adverse roll control problems
• B. Improved control authority
• C. Decreased drag
• D. Higher climb rate

Answer: (A)

Ice on flight control surfaces makes them heavier, less flexible, and aerodynamically uneven. When ailerons or other controls accumulate ice, their ability to deflect in response to pilot input is reduced, and the hinge mechanism can become stiff or bind. This loss of control effectiveness can produce unexpected or opposite roll tendencies, especially at critical speeds or near stall, creating adverse roll control problems. Ice also tends to increase drag and can alter the surface’s lift characteristics, further degrading handling. The idea that control authority would improve, drag would decrease, or climb performance would increase does not fit with how ice affects surfaces—the overall effect is a reduction in controllability and performance, not an enhancement.
