Aircraft noise in the vicinity of airports presents a major challenge for the future development of civil aviation. A crucial prerequisite in the definition of effective noise-mitigation strategies is the capability to model future airport noise and consider underlying noise-relevant effects. In a recent study, we have presented a framework that is capable of modelling future flight plans, noise emissions at the aircraft level, and ultimately airport-level noise exposure. The novel contribution of this paper is an application of the framework by studying future airport noise of a typical two-runway airport. Future fleet mix, flight plans and airport noise are modelled up to 2040. Furthermore, the impact of airport capacity constraints on resulting day-evening-night levels is examined.
