BADA consists of a set of aircraft models used at the EEC and other European research institutes for aircraft trajectory simulation. For the 2002 statistics, a 2-month traffic sample was used covering December & July of 2003.
The results show that the 84 aircraft types within BADA 3.5 cover 76.48% of the European air traffic for the whole period compared to the annual target of 90%. The addition of 13 more original aircraft types would bring the coverage to the target 90%. The synonym aircraft occupy a further 20.58% share of the total traffic.
