SEA Stakeholder Advisory Round Table (StART) state legislative priorities: proposed final adoption
The Port of Seattle and nearby communities outlined five state legislative priorities for Seattle-Tacoma International Airport (SEA) in October 2024, focusing on reducing the airport's impact on surrounding neighborhoods. Key goals include repairing noise insulation for affected homes, identifying future regional airport capacity, improving air quality, expanding sustainable aviation fuel use, and reducing ground transportation emissions. These priorities reflect a partnership between the Port of Seattle and the Washington State Legislature to address both community concerns and the airport's long-term growth challenges. -

Missed approach/go-around operations and how the FAA manages demand
This FAA presentation, prepared for the Seattle-Tacoma International Airport (SEA) Stakeholder Advisory Round Table, explains what missed approaches and go-arounds are and why they occur. A missed approach happens when a pilot cannot safely continue landing due to factors like fog, bad weather, an unstable approach, or an unclear runway, while a go-around is a routine safety maneuver initiated by either the pilot or air traffic control when landing conditions are unsafe. Both procedures result in aircraft climbing away from the airport and potentially flying over nearby communities, contributing to noise impacts in the area. -

Sustainable Airport Master Plan near-term projects environmental review
The Port of Seattle is conducting an environmental review of near-term construction projects at Seattle-Tacoma International Airport (SEA) under the FAA's National Environmental Policy Act (NEPA) process, with a public comment period running October–November 2024. Originally built in 1949 to serve half a million passengers per year, SEA now handles over 50 million annually and is projected to reach 67.2 million passengers by 2035 as the Central Puget Sound region's population grows. The Sustainable Airport Master Plan outlines infrastructure improvements needed to accommodate this long-term growth. -

Pages from June 10, 2024 Aviation Noise Working Group Part 150 Study Technical Review Committee Meeting #1_0001
Slide 23 from a Port of Seattle presentation on aircraft noise at Seattle-Tacoma International Airport, explaining key noise metrics including Single Event Sound Level (SEL), Hourly LEQ, and Day-Night Level (DNL). The right panel illustrates that identical DNL 65 levels can result from 1 event/day at SEL 114.4 dBA, 10 events/day at SEL 104.4 dBA, or 100 events/day at SEL 94.4 dBA. -
DNL65 Airplane Modeling Graphic Pages from June 10, 2024 Aviation Noise Working Group Part 150 Study Technical Review Committee Meeting #1_0001
This aviation noise education graphic illustrates that Day-Night Average Sound Level (DNL) 65 dBA can result from 1 event/day at SEL 114.4 dBA, 10 events/day at SEL 104.4 dBA, or 100 events/day at SEL 94.4 dBA. The diagram uses aircraft icons to visually demonstrate how DNL integrates both frequency and intensity of noise events into a single equivalent metric.
