Airbus A310-300, Airline Club Wiki

The Airbus A310-300 is almost similar A310-200, but adds extra range with its increased MTOW. This enables the plane to carry extra fuel without sacrificing passengers, thus improving the range. There is an -300 variant that can change between cargo and passengers by removing the seating. A fuel distribution system controlled by a computer moves fuel to change the plane's center of gravity.
