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.

Notes

Port Of Seattle Sound Information fact sheet (FACT14A, revised 3/31/93) explaining Sea-Tac Airport jet aircraft flight track plots, including north flow and south flow daytime turbojet arrival and departure patterns. Covers the ARTS (Automated Radar Terminal System) data used to generate flight tracks, explains why aircraft flying identical procedures do not follow identical ground tracks due to pilot technique, air traffic control, weather, and aircraft performance variations. Includes two flight track map plots: North Flow October 4, 1994, 06:00–22:00 hours, and South Flow October 21, 1994, 06:00–22:00 hours, showing Sea-Tac departures (green) and Sea-Tac arrivals (red) over Puget Sound, Mercer Island, Duwamish River, and Tacoma areas.
