The A330 's body is also similar to the older Airbus A300 , and the computers and systems ( like the fly-by-wire system ) are similar to the Airbus A320 family of aeroplanes . Also , both the A330 and A340 are built at the same place : Toulouse-Blagnac Airport in Toulouse in France . Airbus also decided that the A330 and A340 would share a common cockpit with the A320 .
