← Nature & AnimalsWhich aerodynamic effect occurs when dihedral angles of raptor flight feathers are reduced suddenly?
A)Increased stall speed results rapidly✓
B)Soaring efficiency increases notably
C)Control authority decreases erratically
D)Drag decreases in thermals visibly
💡 Explanation
Increased stall speed results because disruption of airflow over the wing utilizes boundary layer separation, causing a rapid loss of lift; therefore stall, caused by decreasing dihedral angles on wing feathers is the effect, rather than increased soaring or decreased drag.
