Equitable Aircraft Noise-Abatement Departure Procedures

摘要

This paper deals with the optimization of aircraft noise-abatement departure procedures. A multicriterianoptimization strategy is presented, where the fairness of the optimal trajectories is assessed vis-à-vis the differentnnoise-sensitive locations around the airport of study. This equitable optimization is formulated as the minimization ofnthe maximum noise-annoyance deviation regarding all considered locations. This strategy is complemented with anniterative lexicographic optimization algorithm which, in turn, guarantees the Pareto efficiency condition of the finalnsolution. Aircraft operating costs are also considered by neglecting the marginal benefits of noise reduction below ancertain threshold value. An application example is shown (as an illustrative case) based on a departure of runway 02nat Girona airport in Catalonia, Spain. The results show the feasibility of this technique, which is intended to be usednby procedure designers or airport authorities.
