A procedure for the calculation of aircraft noise, especially of noise distributions at airports, was developed. The air traffic is directly simulated in the computer. Flight trajectories are discretized in a close meshed series of emission points to calculate noise evolution. Aircraft directional characteristics and meteorological conditions, especially ray curvature due to wind and temperature gradients, are taken into account. This procedure gives a real time histogram of the noise, comparable to an in situ measurement.
