Airbus' A320 dedicated test aircraft performed the world's first flight using four-dimensional optimized and upgraded Air Traffic Management (ATM) technology, achieving this milestone while operating from Toulouse, France to Copenhagen, Denmark on 10 February 2012. The project is called I-4D (Initial-4D), and it provides benefits that include a significant reduction of fuel burn and C02 emissions, a decrease of delays and therefore shorter and smoother flights for passengers.
