    Introduction to aviation forecasting

    This presentation, delivered on February 25, 2026, introduces the fundamentals of aviation forecasting as part of the airport planning process.

    StART Aviation Noise Working Group Meeting Summary — February 9, 2026

    The StART Aviation Noise Working Group met in February 2025 to review Seattle-Tacoma International Airport's Late Night Noise Limitation Program, which tracks aircraft noise between midnight and 5 AM and found 8% of operations exceeded thresholds in Q4 2025. The group decided against expanding the program to cover 11 PM–midnight, as most flights in that hour already use quieter aircraft and the change would triple monitored operations with little noise-reduction benefit. Additional updates covered a significant drop in propeller aircraft turns over Burien, progress on the Sound Insulation Program, and action items including a new 5–6 AM operations analysis and a multi-year trends chart.

    Motion to consolidate petitions denied

    The U.S. Court of Appeals for the Ninth Circuit issued a procedural order on February 5, 2026, in two consolidated cases where Vashon Island Fair Skies and the City of Burien are challenging Federal Aviation Administration decisions, with the Port of Seattle as an intervenor. The court denied a request by petitioners to file separate opening briefs, and also denied—without prejudice—their request to file an oversized consolidated brief, requiring them to resubmit that request with a copy of the proposed brief attached. Key upcoming deadlines set by the court include the consolidated opening brief due March 30, 2026, the answering brief due April 29, 2026, and the Port of Seattle's intervenor brief due May 13, 2026.
