← Nature & AnimalsWhich aerodynamic effect causes lift augmentation when a soaring hawk flares before landing?
A)Increased wingtip vortex formation
B)Boundary layer transition to turbulence
C)Chordwise pressure recovery decrease
D)Leading-edge vortex flow stabilization✓
💡 Explanation
During a flare maneuver, angle of attack increases dramatically and at certain angles leading-edge vortex flow stabilization results because the vortex remains attached rather than stalling, augmenting list. Therefore greater lift is maintained, rather than increase wingtip drag, encourage flow disruption, or diminish pressure.
