← TechnologyWhich consequence results when excessive aerodynamic stress overwhelms an aircraft's control surface actuator using a fly-by-wire system?
A)Unrecoverable control surface reversal✓
B)Increased control surface dampening
C)Decreased flight control sensitivity
D)Elevated actuator thermal conductivity
💡 Explanation
Unrecoverable control surface reversal occurs because exceeding actuator force limits triggers aeroelastic flutter facilitated by control surface deflection, therefore airspeed increases destabilize the system, rather than damping oscillations near structural frequencies.
