Minutes from a Technical Advisory Committee meeting on the Sea-Tac Airport Noise Exposure Forecast Update, an approximately $80,000 study partially funded by the FAA and expected to be completed by July 1981. The meeting covered two key study tools — the Integrated Noise Model (INM), a computer program that estimates aircraft noise using Ldn (day-night average sound level) measurements, and the Sea-Tac Noise Monitoring System (NMS). Committee members raised concerns about using averaged noise metrics, debating whether single-event noise levels or a 'misery index' tracking flights above a threshold decibel level would better reflect community impact.

This document outlines the work program for a Noise Exposure Forecast Update at Sea-Tac International Airport, dated September 17, 1980. The program is divided into six phases covering study scoping and funding, INM (Integrated Noise Model) verification, supplemental data collection, real-time forecasting, report generation, and public/administrative involvement. It details specific tasks, staff assignments, and procedures aimed at validating or revising noise impact programs developed under the Sea-Tac/Communities Plan, in compliance with the Aviation Safety and Noise Abatement Act of 1979.

This circa-1980 visitor guide for Seattle-Tacoma (Sea-Tac) International Airport describes the layout and services available to travelers, including the automated Satellite Transit System—an underground railway connecting the main terminal to the North and South Satellites and Concourses B and C. The brochure covers amenities such as banking, dining, a nursery lounge, and Travelers' Aid, and includes a terminal map showing airline gate assignments and ground transportation options. It also notes that the Port of Seattle received a 1975 Federal Aviation Administration award for its attention to land compatibility, landscaping, and contemporary art throughout the airport.
