    Consequences of parallel runway operations at Sea-Tac Airport

    This presentation examines the consequences of runway configuration changes at Seattle-Tacoma International Airport (Sea-Tac), including louder departure noise for Burien residents, reduced airport capacity, and potential FAA workaround taxi routes. It references Seattle Air Traffic Control Tower standard operating procedures for opening and closing runways, and analyzes the feasibility of simultaneous parallel runway operations under FAA Order JO 7110.65. Key technical challenges identified include the need to relocate the Instrument Landing System, extreme ramp congestion, and the possibility of displacing the Runway 34R threshold by approximately 3,400 feet to achieve parallel threshold alignment.

    Seattle-Tacoma International Airport map

    This document is an airport diagram of Seattle-Tacoma International Airport showing runways, taxiways, run-up areas, and terminal facilities. Handwritten annotations in red ink reference noise abatement procedures, including a note about 'General Aviation' operations and restrictions on runways, specifying limits such as '650 landings' and directions (East/West). Additional handwritten notes at the bottom outline runway use prohibitions from 10 PM to 6 AM, with exceptions for 50% power run-ups and full-power checks limited to 2 minutes.

    Paine Field Aerial View

    Aerial photograph looking north showing Paine Field (KAWO/PAE) with runway 34 threshold markings visible in the foreground, and the Boeing Everett production facility — the world's largest building by volume — visible in the background with characteristic blue-roofed structures. Puget Sound and the city of Everett are visible in the upper background. This facility is distinct from Sea-Tac Airport.

    Highline Forum: Are arrivals lower now than they were a couple of years ago?

    A Highline Forum presentation examining whether aircraft arrival numbers at Seattle-Tacoma International Airport have decreased compared to a few years earlier. The analysis uses one month of arrival flight track data from June 2013, June 2015, and June 2017 across Sea-Tac's three parallel runways (16L/34R, 16C/34C, and 16R/34L). June was chosen as a representative month because it typically features a balanced mix of north and south flow operations, Instrument Landing System (ILS) and visual approaches, and an average volume of aircraft traffic.
  • Aircraft Adjacent to 179 Drop From Third Runway

    Engineering cross-section drawing labeled 'Exhibit 2: Aircraft Adjacent to 179 Drop From Third Runway,' produced by the Port of Seattle / Sea-Tac International Airport for the Miller Creek Instream and Buffer Enhancements project. The drawing (sheet 291Z81C17, detail S11A-XXXI-C11) shows the embankment profile with an MSE retaining wall, replacement channel, silt fence, security road, rock underdrain, and a minimum 50-foot creek buffer for Miller Creek, with elevation and horizontal scales and a wide-body aircraft silhouette for scale reference.
  • Aging, unreliable runway safety device leaves U.S. airports vulnerable

    By Alan Levin  A crucial safety system that’s relied on to avoid potentially fatal collisions at major U.S. airports is aging and plagued by outages that have left travelers unprotected for months at a time. At some airports, it hasn’t ever been installed. The technology — which tracks vehicles on or near runways to alert
  • Future Airport Expansion With An Independent Runway One Mile East of 34R

    Architectural/planning drawing titled 'Future Sea/Tac Airport Expansion with an Independent Runway One Mile East of 34R,' showing Plan A layout with an independent runway 4,300 feet west of runway 34R. The drawing, credited to Don Getsick, depicts proposed runways (East Runway B, West Runway A), taxiways, satellite terminals, tramway, underground tram, off-site parking/hotel/business core, and surrounding streets including International Blvd, Des Moines Way S, and 1st Ave South, with Angle Lake and Bow Lake visible.
  • Detroit Metro Airport (DTW)

    Overhead aerial photograph showing a large commercial airport with multiple parallel runways, terminal complexes, and taxiway systems embedded within a flat, densely developed suburban landscape. No visible text, watermarks, or captions are present to confirm the specific airport identity, though the runway configuration and surrounding grid pattern are consistent with a major Midwestern U.S. hub airport.
