440 - Long-term noise prediction in a busy airport

Abstract
A detailed comparison of measured and simulated noise events occurred during three busy weeks in a big eurpean airport has been carried out. Measured data consist in overflight SEL values gathered in 17 Noise Monitoring Terminals (NMT) and then matched with radar tracks aquired from ATC. Simulations has been performed using FAA's software INM vers. 6.1 introducing a non-standard single-flight-noise-event approach with the aim to reduce bias related with statistical modelling of aircraft operations and their dispersion around a backbone track. Thanks to this, it is possible to evaluate differences between measured and simulated geometric parameters characterizing the Closest Point of Approach (CPA) in terms of distance, altitude and elevation angle referred to each receptor. Other variables, as daily meteorological conditions and receptors height, have been considered in order to reduce their relative weight. Thus, it is possible to emphatize the influence of SEL variance on daily LAeq based metrics.
