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.
In a banked turn at constant altitude, the load factor is equal to 1/cosÎ¸. We can see that the load factor in straight and level flight is 1, since cos(0) = 1, and to generate sufficient lift to maintain constant altitude, the load factor must approach infinity as the bank angle approaches 90Â° and cosÎ¸ approaches zero.
