ATPL - AGK SET 2 (46/91)verified to pass 2023/2024

ATPL - AGK SET 2 (46/91)46. Which is a purpose of wing-mounted vortex generators? A. Reduce the drag caused by supersonic flow over portions of the wing. B. Increase the onset of drag divergence and aid in aileron effectiveness at high speed. C. Break the airflow over the wing so the stall will progress from the root out to the tip of the wing. - correct answers A. Reduce the drag caused by supersonic flow over portions of the wing. 47. Which is a purpose of wing-mounted vortex generators? A. Delays the onset of drag divergence at high speeds and aids in maintaining aileron effectiveness at high speeds. B. Breaks the airflow over the wing so the stall will progress from the root out to the tip of the wing. C. Increase the onset of drag divergence and aid in aileron effectiveness at low speed. - correct answers A. Delays the onset of drag divergence at high speeds and aids in maintaining aileron effectiveness at high speeds. 48. What affects indicated stall speed? A. Weight, load factor, and power. B. Load factor, angle of attack, and power. C. Angle of attack, weight, and air density. - correct answers A. Weight, load factor, and power. 49. How can turbulent air cause an increase in stalling speed of an airfoil? A. An abrupt change in relative wind. B. A decrease in angle of attack. C. Sudden decrease in load factor. - correct answers A. An abrupt change in relative wind.
