Which risk increases when a commercial airliner exceeds critical buffeting speed?

💡 Explanation

Exceeding buffeting speed exposes the wing to severe turbulence; because the unsteady pressure gradients of airflow separation induce large, rapid control surface oscillations. This aeroelastic flutter phenomenon may cause a stall. Therefore, stall risk increases, rather than increased fuel efficiency, stabilized thrust, or maximized L/D.
