← ScienceWhich risk increases when an aircraft wing exceeds its critical angle-of-attack?
A)Complete stall and loss of lift✓
B)Increased skin friction drag linearly
C)Elevated aileron effectiveness margins
D)Minimized parasitic drag coefficient values
💡 Explanation
A stall occurs because increased angle-of-attack causes turbulent airflow (flow separation) over the wing, therefore lift is suddenly lost, rather than gradual drag increase or control enhancements that might dominate different conditions.
