Welcome to Southern Sydney Angiography We are proud to introduce Southern Sydney Angiography, a state of the art interventional radiology unit! Southern Sydney Angiography is an Interventional Radiology Service that operates in the St George Private Hospital.
During takeoff and landing, the flaps on the back of the wing extend downward from the trailing edge effectively altering the shape of the wing. This change enables it to divert more air generating more lift. This change also increases drag, which helps a landing airplane slow down while requiring more thrust during takeoff.
the wings will no longer support the airplane in flight. Ground effect is the result of the interference of the surface of the Earth with the airflow patterns about. an airplane. Answer (B) is incorrect because induced drag is decreased. Answer (C) is incorrect because the disruption. of wing-tip vortices increases lift.
