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.
An aircraft stall is an aerodynamic condition in which an airplane exceeds its given critical angle of attack and is no longer able to produce the required lift for normal flight.This type of stall should not be confused with an engine stall.In an airplane, a stall has nothing to do with the engine, and is only defined as the aerodynamic loss of lift that occurs when an airfoil (i.e., the wing of the airplane) exceeds its critical angle of attack.Angle of Attack.n an airplane, a stall has nothing to do with the engine, and is only defined as the aerodynamic loss of lift that occurs when an airfoil (i.e., the wing of the airplane) exceeds its critical angle of attack.
