← TechnologyWhich outcome increases in a fly-by-wire aircraft when airspeed decays below the preprogrammed minimum?
A)Excessive control surface oscillations✓
B)Increased stall margin protection
C)Reduced autopilot system authority
D)Decreased structural load tolerance
💡 Explanation
Excessive control surface oscillations will increase because active flutter control relies on sufficient airspeed for aerodynamic damping. Therefore, control surfaces become prone to rapid, divergent movements, rather than maintaining stability at lower speeds.
