← Nature & AnimalsWhich wing deformation occurs when a soaring bird exceeds its critical wing loading during thermal updraft use?
A)Tip twisting induces stall recovery
B)Leading-edge twisting delays flutter
C)Camber reduction decreasing lift✓
D)Increased profile drag causing speed loss
💡 Explanation
When a bird's wing exceeds critical wing loading, elastic deformation causes camber reduction, decreasing the wing's lift because the wing structure cannot maintain its shape optimally. Therefore camber reduction results, rather than stall recovery, flutter delay, or speed loss, which involve different aerodynamic control mechanisms.
