TagFlight Tracks(61)

This Port of Seattle document shows a flight-track map of Seattle-Tacoma (Sea-Tac) Airport activity on May 24, 2006, between 5:45 p.m. and 8:30 p.m. During this period, south-flow jet aircraft deviated from their standard routes due to weather conditions, as confirmed by the FAA. The map distinguishes arrivals, departures, fly-overs, training flights, and overshoots by color, illustrating how unusual flight paths spread noise impacts across a wider area of the surrounding region.

This document is the Final Report (July 2002) of the FAR Part 150 Study Update for Seattle-Tacoma International Airport, a federally guided process to assess and manage aircraft noise impacts on surrounding communities. Technical Appendix Two (Appendices 7–26) compiles key study materials including community advisory committee reports, land use recommendations, flight track analyses, public hearing transcripts, noise data, and Port of Seattle resolutions. The report represents the culmination of extensive community involvement and technical review aimed at updating the airport's noise abatement and sound attenuation programs.

In April 2000, the Des Moines, Washington City Council adopted Resolution No. 882, formally expressing its preference for the 'South Flow Two Tracks' flight path alternative proposed in the Port of Seattle's Part 150 Study. The Council found that existing flight tracks placed a disproportionate share of aircraft noise on Des Moines residents and businesses, and determined that the two-track alternative would provide the greatest noise relief. The City Manager was directed to submit the resolution to the Port of Seattle as the city's official position on southbound departure routes from Sea-Tac International Airport.

This Port of Seattle document explains flight track plots for propeller aircraft at Seattle-Tacoma International Airport, showing the ground paths of arrivals and departures during daytime hours (6 a.m. to 10 p.m.) for both north and south traffic flows. Aircraft flight paths vary due to pilot technique, weather, and air traffic control, meaning planes assigned the same route will not follow identical tracks. On average, Sea-Tac experiences south flow conditions 65% of the year and north flow 35%, with propeller aircraft kept on separate tracks from faster jet aircraft.

This Port of Seattle document explains flight track plots for Seattle-Tacoma International Airport, which map the ground paths of jet aircraft arrivals and departures during daytime hours (6am–10pm). It describes how wind conditions determine whether aircraft fly in a north or south flow pattern, with south flow occurring about 65% of the year. The document also notes that even aircraft following identical routes will not fly the exact same path, due to variations in pilot technique, weather, air traffic control, and aircraft performance.

This Port of Seattle document explains flight track plots for Seattle-Tacoma International Airport, which are overhead graphic illustrations showing the ground paths of arriving and departing jet aircraft over a 24-hour period, separated into daytime and nighttime operations for both north and south traffic flows. The data is sourced from the FAA's Automated Radar Terminal System (ARTS). Notably, the document emphasizes that even aircraft following identical routes will not fly the exact same path, as factors like pilot technique, air traffic control, weather, and aircraft performance cause flight corridors to widen with increasing distance from the airport.

These two Port of Seattle Flight Track Sample maps compare jet aircraft arrival and departure patterns at Seattle-Tacoma International Airport (SEA) under south flow conditions, one from March 22, 1989 (pre-4 Post) and one from March 31, 1991 (4 Post). Both charts plot all jet flight tracks between approximately 4:30–24:00 and 6:00–22:00 respectively, showing how flight paths over the Seattle region shifted between the two periods. The maps are annotated to highlight southbound departures and arrivals over Seattle, serving as visual evidence for noise impact analysis related to airport runway and procedure policy changes.

This 1990 document outlines a comprehensive package of noise abatement actions for Seattle-Tacoma International Airport, agreed upon by a Mediation Committee on March 31, 1990. It covers measures such as nighttime flight restrictions, soundproofing programs for nearby homes and public buildings, improved flight corridors, and a new noise management monitoring system. According to the technical consultant involved, full implementation of these agreements could reduce noise levels by approximately 50% for communities surrounding the airport.
