The optimisation of aircraft noise abatement proceduresinvolves several conflicting factors, including severalnoise sensitive locations and aircraft operating costs. This paperpresents some strategies that aim at better assessing these compromiseswhen optimising site-specific noise abatement departureprocedures that take into account the actual populated areas,their type and distribution, the hour of the day where thetrajectory is supposed to be flown and the aircraft type. A specialemphasis is given to the fairness of the trajectory with regardsto the populated areas exposed to noise. In this context, a noiseannoyance deviation index is proposed as optimisation objective.Moreover a multi-objective optimisation strategy, employinggoal, lexicographic-egalitarian and hierarchical optimisationtechniques is presented. An illustrative example is given withthe design of the East departures at Girona airport, Catalonia(Spain). Results point out how the noise annoyance impactof current operational procedures can be significantly reducedby the optimised trajectories and show, as well, an importantdependency on the type of aircraft and the hour of the day.
