This paper describes AirTraf ver. 1.0 for climate impact evaluations that performs global and long-Term air traffic simulations with respect to aircraft routing options. AirTraf was developed as a new submodel of the EClIAM5/MESSy Atmospheric Chemistry (EM AC) model. The real flight plan, Eurocontrol's Base of Aircraft Data (BADA) and ICAO engine performance data were employed. Fuel and emissions were calculated by the total energy model based on the BADA methodology and DLR fuel flow correction method. The flight trajectory optimization was performed by the Genetic Algorithm (GA). The Air Traf simulation was demonstrated on-line with the tlight time routing option for a specific winter day. 103 trans-Atlantic flight plans were used, assuming Airbus A330-301 aircraft. The results confirmed that AirTraf properly works on-line and GA successfully found the time-optimal flight trajectories, reflecting local weather conditions.
