This October 2009 FAA Air Traffic Organization document explains the terms, techniques, and programs used to manage the flow of air traffic across the National Airspace System. It covers topics such as ground delay programs, ground stops, severe weather avoidance, rerouting strategies, and coordination tools used by traffic management specialists. While focused on national-level airspace operations rather than airport-specific noise policy, it provides useful background on how flight scheduling and routing decisions are made system-wide.

This 1990 Final Environmental Assessment, prepared by the FAA's Air Traffic Division in Seattle, evaluates proposed changes to arrival and departure flight routes at Seattle-Tacoma International Airport. The document was signed by Air Traffic Division Manager Temple H. Johnson, Jr. on March 27, 1990, and examines the potential environmental impacts of rerouting aircraft traffic in and out of Sea-Tac. It serves as an official federal record relevant to noise and environmental policy affecting communities around the airport.

This 1990 Final Environmental Assessment, published by the U.S. Department of Transportation's Federal Aviation Administration, examines proposed changes to air traffic arrival and departure routes at Seattle-Tacoma International Airport. Volume II of the document compiles public comments received in response to the Draft Environmental Assessment, reflecting community input on how the proposed route changes could affect noise and other environmental conditions in the Seattle, Washington area.

This 1989 FAA draft Environmental Assessment examines proposed changes to arrival and departure flight routes at Seattle-Tacoma International Airport, aimed at reducing air traffic congestion and improving airspace efficiency. The document identifies a key inefficiency: during good weather and peak demand, south-landing capacity (42 aircraft/hour) was significantly lower than north-landing capacity (56 aircraft/hour), largely due to a requirement routing turbojet aircraft through Elliott Bay. The assessment traces the issue back to noise abatement procedures established since 1970 that prioritized limiting jet overflights in certain Seattle metropolitan areas over operational efficiency.

The 1989 Airport Capacity Enhancement Plan, produced by the FAA and U.S. Department of Transportation, outlines efforts to increase airport capacity and efficiency across the U.S. air system without compromising passenger safety or the environment. It identifies causes of capacity and delay problems, projects the impact of increased air traffic over the following decade, and describes planned projects covering airport development, airspace procedures, new equipment, and capacity planning studies. Note: this document addresses national airport capacity issues broadly and does not focus specifically on Sea-Tac Airport or local noise policy.

This 1988 Federal Aviation Administration report outlines the Airport Capacity Enhancement Plan, which aimed to increase airport capacity and efficiency across the U.S. air system without compromising passenger safety or environmental impact. It identifies causes of capacity and delay problems, forecasts the effects of growing air traffic over the following decade, and describes FAA projects targeting four key areas: airport development, airspace control procedures, equipment and systems upgrades, and capacity planning studies. Note that while this document addresses national airport capacity issues broadly, it does not specifically focus on Sea-Tac Airport noise policy.
