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.
Stability about the airplane's longitudinal axis, which extends form nose to tail, is called lateral stability. This helps to stabilize the lateral or rolling effect when one wing gets lower than the wing on the opposite side of the airplane. There are four main design factors which make an airplane stable laterally-dihedral, keel effect, sweepback, and weight distribution.
