  • Airport Runway Layout Diagram (For Illustration Purposes Only) — Terminal, Tower, Customs, and Mid-Field Cargo Complex

    This is an airport diagram showing multiple runways including one labeled 10502 x 199 feet and another 9500 x 150 feet, with facilities marked including a Main Terminal, U.S. Customs, Tower, Mid-Field Cargo Complex, and General Aviation Parking. Runway end identifiers visible include 10, 28, 15R, 33L, 33R, and 75L, consistent with a large international airport layout, though no airport name or ICAO/IATA code is explicitly shown.

    Tango Taxiway

    A large lighted X-shaped runway closure marker mounted on a mobile orange tower unit, positioned on an airport tarmac. The device uses orange panel boards forming an X pattern along with black light fixtures mounted on yellow arms, consistent with FAA-standard runway closure markings used to signal that a runway is closed to aircraft.

  • Center Runway Reconstruction

    The Port of Seattle completed reconstruction of the center runway (designated as 16C/34C) at Seattle-Tacoma International Airport in 2015. The runway was originally built in 1969 and had some brief closures during 2016 in order to complete adjoining projects with taxiways and blast pads. The project included installation of a new LED runway lighting system and an

    Airport basics | Port Of Seattle

    Seattle-Tacoma International Airport handled 49.8 million passengers and 438,391 aircraft operations in 2018, ranking 8th in the U.S. by passenger volume. A noise compatibility study forecasted total annual aircraft operations to grow from approximately 301,870 in 2009 to 399,200 by 2021, driven by increases in both domestic and international air carrier activity. The airport operates three category IIIb certified runways and is dominated by Alaska Airlines, which carries over 50% of its passengers.

    ISBRG One Departure (RNAV) Standard Instrument Departure Chart, Seattle-Tacoma International Airport

    The ISBRG One Departure is an RNAV instrument departure procedure at Seattle-Tacoma International Airport (SEA) available only between 10 PM and 6 AM local time, designed to route departing aircraft on specific northwestward flight paths. Aircraft departing runways 34L, 34C, and 34R follow assigned headings and waypoints—climbing to 940 feet, then proceeding through fixes such as WUREL, ATOME, BREMM, and ISBRG—while maintaining a top altitude of 9,000 feet. The procedure's nighttime-only restriction and structured routing reflect noise-abatement considerations for communities surrounding the airport.

    Aircraft arrivals analysis: Progress update

    This January 2018 progress update from ESA presents an analysis of aircraft arrivals at Seattle-Tacoma International Airport (SEA), examining whether notable changes occurred between 2013, 2015, and 2017. The study uses radar flight track data from July and December of each year to compare fleet mix, runway usage, and aircraft altitudes at six nautical miles from the airport. Key questions addressed include whether arrival numbers increased, whether traffic flow patterns shifted between north and south flow, and whether arriving aircraft were flying at different altitudes over the study period.

Issues

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.
