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 air moving over the top must speed up more than the air below the wing, because of conservation of mass. As it moves faster, the air on top of the wing also loses pressure and push. The slower moving air below the wing maintains more of its pressure, which pushes the wing, and the plane, up. Terms Of Use
