← Nature & AnimalsWhich effect occurs when a bird exceeds its critical wing loading during takeoff?
A)Induced stall from boundary layer separation✓
B)Increased lift due to accelerated airflow
C)Reduced drag due to laminar flow increase
D)Enhanced maneuverability with rapid turning
💡 Explanation
When wing loading is excessive, the airflow cannot effectively adhere to the wing's surface due to viscosity, causing premature boundary layer separation and inducing a stall situation because the angle of attack is too high for the airspeed. Therefore induced stall results, rather than increased lift, laminar flow, or maneuverability that require stable accelerated airflow at lower loading.
