A cargoaircraft (also known as freightaircraft , freighter, airlifter or cargo jet) is a fixed- wing aircraft that is designed or converted for the carriage of cargo rather than passengers. Such aircraft usually do not incorporate passenger amenities and generally feature one or more large doors for loading cargo . Freighters may be operated by civil passenger or cargo airlines, by private individuals or by the armed forces of individual countries (for the last see military transport aircraft ).
Aircraft designed for cargoflight usually have features that distinguish them from conventional passenger aircraft : a wide/tall fuselage cross -section, a high- wing to allow the cargo area to sit near the ground, a large number of wheels to allow it to land at unprepared locations, and a high-mounted tail to allow cargo to be driven directly into and off the aircraft .
Cargoaircraft represent a small proportion of the overall air freight market . The majority is carried in special ULD containers in the cargo holds of normal passenger aircraft .
