Aircraft Noise: FAA Could Improve Outreach Through Enhanced Noise Metrics, Communication, and Support to Communities, Report to Congressional Requesters [open pdf - 2MB]
From the Highlights: "As part of its effort to modernize the National Airspace System, FAA [Federal Aviation Administration] has been implementing new flight paths using satellite-based navigation, called PBN [performance-based navigation], at airports across the country. GAO [Government Accountability Office] reviewed FAA's implementation of PBN with regard to noise and FAA's related public outreach activities. This report discusses: (1) how FAA assesses potential noise impacts for proposed PBN changes; (2) the extent to which FAA's noise impact analysis conveys expected changes; and (3) FAA's community outreach related to PBN and actions to improve this outreach."
