Cargo aircraft is now almost out of demand. Its main advantage is the speed of shipment. Its main disadvantage is the cost of freight, which is covered by the speed of shipment allowing to escape the other elements of logistic expenses structure respecting the cost of warehousing. Speed is determined by the rate of covering a specific distance. The fastest is the aircraft. Though the distance for the airfreight is not limited its share in international volume of non-passenger ton-miles is still less than 1%. The capabilities of aircraft are restricted by the load carrying capacity of air-freighters as well as their limited availability. Typically for short distances international cargoes were shipped by passenger flights. It was easy and cost effective but resulted in loss of flexibility and lagging technical development. A jet fright is very expensive therefore its operation is nonscheduled and the stock of exclusively cargo fright jets is very limited. The airports location requires vast open space therefore air fright is rarely integrated into any system with other kinds of transportation but for motor transport. Air fright is used for carrying various cargos. Usually it is used in the case of emergency and rarely as a regular carrier. Thus the key cargoes carried by air are either expensive or perishable goods that justify the high cost of carriage. The other possible objects for air fright are such traditional for logistic operations products as vital assembly parts and components for industrial equipment and production lines. The rates of air fright are determined independently by the airlines in which case the payment is specified as based on the fright rates.
