Cette procédure porte sur une demande d'approbation de plans et de modification du règlement d'exploitation soumise par Genève Aéroport le 2 septembre 2019 et intitulée « Sortie rapide en piste 04 et mesures opérationnelles ».\n\nCes données géographiques sont publiées sous forme de courbes d'exposition au bruit des aéronefs \"décibel par décibel\" et mises à disposition du public sur le site du SITG.\nCeci en attendant l'aboutissement de la procédure en cours et la fixation formelle du nouveau bruit admissible de l'aéroport de Genève par l'autorité de décision fédérale.\n\nLes courbes de type \"enveloppantes\" superposent les courbes de bruit par tranches horaires définies dans l'OPB. L'empreinte au sol de cette courbe enveloppante représente la situation la plus défavorable, toutes périodes confondues.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid":
