Which combination of effects occurs due to icing on airfoils?

• A. Increased lift with reduced drag
• B. Lower maximum coefficient of lift and increased drag
• C. Increased maximum coefficient of lift and stall speed
• D. Reduced stall speed with increased drag

Answer: (B)

When ice accumulates on airfoils, it disrupts the smooth airflow over the wing surface. This irregularity in airflow leads to a lower maximum coefficient of lift, which means the airfoil cannot achieve the same level of lift as it would in a clean condition. Additionally, the presence of ice increases drag because the rough surface increases turbulence and resistance against the airflow. Therefore, the phenomenon of icing on airfoils results in a compromised lift generation capability, alongside an increase in drag forces, making it critical for pilots to understand the dangers posed by icing conditions. This is why the combination of a lowered maximum coefficient of lift and increased drag is consistent with icing effects on airfoils.
