Which risk increases when a commercial airliner encounters sudden, localized turbulence during flight?

💡 Explanation

The risk of elevator control reversal heightens because aeroservoelastic flutter—an interaction between aerodynamic forces, structural elasticity, and control system dynamics—can exceed the system's stable operating range in unsteady flows; therefore, flutter occurs rather than stable dampening of oscillations because of induced vibrations.
