1 Rarely, fistulas occur externally to the skin or internally to another part of the biliary tree, to the pleural cavity or bronchial tree, or to the hepatic artery or portal vein or other vascular structures.
Load factor (aeronautics) In aeronautics, the load factor is defined as the ratio of the lift of an aircraft to its weight and represents a global measure of the stress (load) to which the structure of the aircraft is subjected: where: Since the load factor is the ratio of two forces, it is dimensionless.
This means that free fall is denoted by 0g and level flight by 1g. The ratio between lift and aircraft weight is called the load factor n, where , i.e. n = 0 for free fall, n = 1 for level flight, n > 1 to pull out of a dive and n < 1 to pull out of a climb. The overall load spectrum of an aircraft is captured graphically by so called velocity â load factor (V-n) curves.
