← TechnologyWhich outcome occurs when an aircraft's fly-by-wire system experiences a software glitch influencing control surface inputs to reduce lift?
A)Uncommanded phugoid oscillations are induced✓
B)Elevator flutter generates structural resonance
C)Hydraulic failure locks actuator position
D)Yaw dampers become critically ineffective
💡 Explanation
Phugoid oscillations are induced because a software glitch causes incorrect elevator commands leading to unstable longitudinal motion; the **negative feedback loop** tries to maintain altitude rather than damping down the fluctuation. Therefore only phugoid motion happens, rather than flutter because glitch doesn't induce structural vibrations.
