This FAA presentation from February 18, 2021 explains Section 175 of the 2018 FAA Reauthorization Act, which addresses community noise concerns related to aircraft departure procedures. The law requires the FAA to consider dispersal headings or varied flight paths for new or amended departure procedures that direct aircraft between the surface and 6,000 feet over noise-sensitive areas, but only when the airport operator — not the community directly — formally requests it. Any approved changes must not significantly increase noise over noise-sensitive areas or interfere with the safe and efficient operation of the national airspace system.Open full document
