    Aircraft Noise Reduction Act (H.R. 5205)

    H.R. 5205, the Aircraft Noise Reduction Act, is a bill introduced in September 2025 that would allow owners and operators of general aviation airports to work with the FAA to adjust air traffic and training flight patterns in order to reduce aircraft noise in surrounding communities. The bill protects airports from losing federal funding simply for pursuing these noise-reduction measures and requires community input to be considered in the process. It also directs the Secretary of Transportation to update federal regulations to make noise abatement measures more accessible to general aviation airports.

    National Plan of Integrated Airport Systems (2023-2027): Appendix C — Statutory and policy definitions; data sources; and NPIAS process

    This document from the FAA's National Plan of Integrated Airport Systems (NPIAS) 2023-2027 defines the categories and roles of U.S. airports, ranging from large commercial hubs to small general aviation fields, based on criteria such as annual passenger enplanements, flight operations, and cargo weight. It outlines how airports are classified as Primary (Large, Medium, Small Hub, or Nonhub) or Nonprimary (National, Regional, Local, Basic, or Unclassified), and identifies the 3,287 airports that make up the national airport system. The document also details the data sources used by the FAA to determine each airport's classification and role within the system.

    National Plan of Integrated Airport Systems (2021-2025): Appendix A – List of NPIAS airports with activity and development estimate

    This document is Appendix A of the FAA's National Plan of Integrated Airport Systems (NPIAS) for 2021-2025, which lists airports across the U.S. along with their ownership, category, and 5-year development cost estimates for federally eligible improvements. It defines key terms such as airport categories (Commercial Service, Reliever, and General Aviation), hub classifications based on passenger enplanements, and based aircraft counts. The data was primarily compiled in 2019 and does not reflect changes in airline activity due to the COVID-19 pandemic.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
