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.
Load factor limitations of an aircraft are shown by a graphics called maneuvering envelope or Vân diagram as it shows the load factor versus airspeed in terms of EAS. An example maneuvering envelope is given in Figure 3. An aircraft cannot fly out of the load factor boundaries given by the maneuvering envelope.
