The Airbus A340 was intended to compete with American Jumbo Jets with regards to passenger seating and range.
The Airbus A340 model 600 first took to the sky on April 23 2001. It has the second longest fuselage of any aircraft in the world and the longest of any Airbus aircraft. Four more wheels than other A340 series aircraft have been added to the landing gear to help spread out the aircraft's additional weight.
The four engines of the Airbus A340 operate at slightly less than their maximum certified power for additional efficiency and longer life. Airbus tells us that four smaller engines can be maintained at a lower cost than two larger ones. Four engine operation allows the airplane to fly more direct routes than twin engine aircraft due to restrictive twin engine regulations.
All Airbus A340 series aircraft share similar cockpit designs, avionics, and fly-by-wire controls. This allows pilots to fly other aircraft in the series with less time training.
A total of 377 Airbus A340 aircraft of all types were produced. With the lower cost of fuel and the development of more fuel efficient, reliable engines, airlines have switched to the use of twin engine aircraft.
