This document presents forecasts of aircraft operations at Seattle-Tacoma (Sea-Tac) International Airport and King County International Airport from 1980 to 2000, broken down by aircraft classification and flight category including air carrier, general aviation, and military. It projects that total annual operations at Sea-Tac will grow from approximately 213,600 in 1980 to over 260,800 by 2000, driven largely by increases in larger Class D air carrier aircraft. Peak hour operation estimates are provided for both Visual Flight Rules (VFR) and Instrument Flight Rules (IFR) conditions, offering planners a detailed basis for noise impact and capacity assessments.

A 1982 Port of Seattle memorandum presents draft forecasts of aviation demand for Sea-Tac International Airport and Boeing Field, projecting aircraft operations through the year 2000. The forecasts cover annual take-offs and landings as well as peak-hour traffic under both visual and instrument flight conditions, with Sea-Tac's total annual operations expected to grow from roughly 214,000 in 1980 to over 261,000 by 2000. The document was circulated to FAA, King County, and Washington State DOT representatives for review as part of an airspace capacity and noise planning study.

Port of Seattle memorandum announcing the second Airspace Study Advisory Committee meeting scheduled for February 24, 1982. The agenda includes aviation demand forecasts for Sea-Tac and Boeing Field, discussion of airfield and airspace capacities, and aircraft delays.

A January 1982 letter from the FAA's Northwest Region to the Port of Seattle reviews a draft aviation demand forecast for Boeing Field (BFI) prepared for the SEA/BFI Airspace Study. The FAA requests that the final report include more detailed aircraft mix data by class, a full list of assumptions behind the forecasts (such as economic conditions, fuel costs, and general aviation trends), and a clear indication that the projections are unconstrained. The agency also recommends presenting both high and low forecast ranges to account for uncertainty, particularly in long-range general aviation projections.

Meeting minutes from the Airspace Study Advisory Committee discussing the study of airspace interaction between Sea-Tac Airport and Boeing Field. The committee reviewed the study’s purpose, organization, scope, and schedule, with presentations on air traffic control and local airspace structure.

This document is the agenda for a Port of Seattle Airspace Study Advisory Committee meeting held on November 5, 1981, at the FAA Building at Boeing Field. The meeting covered the study's background, scope of work, and an overview of air traffic control and airspace structure, including approach and departure procedures for Sea-Tac and Boeing Field. Progress updates on a general aviation survey and a Boeing Field control tower survey were also scheduled for discussion.

In October 1981, the Port of Seattle invited the Zone III Committee to join an Advisory Committee for the Sea-Tac International Airport and Boeing Field Airspace Study, which aimed to examine how shared airspace between the two airports affected capacity and congestion. Advisory Committee members would be expected to review study materials, monitor progress, and relay information between the study team and their organizations, meeting no more than eight times over 12 months. The first meeting was scheduled for November 5, 1981, at the Federal Aviation Administration Building at Boeing Field.

Letter from Jean Pihlman, Coordinator of Zone III Committee, accepting invitation to participate in the Port of Seattle’s Airspace Study Advisory Committee. The committee designates Jean Pihlman as representative and Virginia Dana as alternate, offering cooperation for the study completion.
