Which risk increases when a swept-wing aircraft experiences ice accretion near the wing root?

A)Stall speed asymmetry increases greatly
B)Aileron reversal becomes more likely
C)Engine nacelle icing intensifies locally
D)Rudder effectiveness rapidly diminishes

💡 Explanation

Icing near the wing root preferentially degrades lift there; consequently, asymmetric stall occurs more readily. This is due to disrupted airflow and premature boundary layer separation because ice acts as flow disturbance rather than maintaining smooth airflow, therefore increasing stall speed unevenly than affecting controls.
