← ScienceWhich risk increases when an aircraft, designed with passive wing load alleviation, experiences an unexpected wind gust?
A)Flutter instability becomes more likely.✓
B)Lift abruptly decreases, causing stall.
C)Control surfaces experience irreversible damage.
D)Induced drag reduces flight efficiency.
💡 Explanation
Flutter instability becomes more likely because the sudden angle of attack change may excite aeroelastic modes. Therefore, flutter initiation risk is higher, rather than lift stall or control surface damage, since structural feedback changes drastically thanks to aeroelastic frequency shift.
