← Nature & AnimalsWhich aerodynamic consequence results when a hawk loses several primary flight feathers unevenly on one wing?
A)Increased stall speed due to asymmetry✓
B)Improved gliding efficiency from vortex reduction
C)Reduced drag from decreased surface area
D)Enhanced maneuverability from disrupted airflow
💡 Explanation
When uneven feather loss occurs, the wing's lift distribution becomes asymmetric, causing increased induced drag and a shift in the center of pressure because one side generates less lift. Therefore, increased stall speed results due to asymmetry, rather than improved gliding, reduced drag, or enhanced maneuverability which require balanced airflow.
