Which aerodynamic effect compromises an aircraft's stability during icing?

💡 Explanation

Icing increases stall speed because ice accretion disrupts airflow, promoting premature boundary layer separation; therefore an aircraft stalls at unexpectedly low angles of attack, rather than maintaining lift through gradual angle increase under normal conditions.
