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.
Airplanes are pressurized because the air is very thin at the altitude they fly. The average passenger jet has a cruising altitude of about 30,000 to 40,000 feet. At this altitude humans canât breathe very well and our body gets less oxygen. This is called hypoxia and can cause slower thinking, dimmed vision, and death.
