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.
Figure 2 shows variation of the load factor with bank angle. The load factor is not dependent to aircraft weight and size, as implied by previously given equations. Whatever the type of aircraft is, same load factors apply for same bank angles. The load factor limitations of aircraft are defined by airworthiness regulations such as, FAR23/JAR23 for small aircraft, and FAR25/JAR25 for large aircraft.
