This appendix from a 2012 Environmental Assessment documents the published arrival flight procedures at Seattle-Tacoma International Airport that would be affected by proposed changes to how aircraft approach the airport. It includes detailed charts for routes such as the JAWBN Three Arrival and Olympia Seven Arrival, showing waypoints, altitudes, and speed restrictions for aircraft arriving from various directions including Canada and southern Washington. These procedures define the flight paths aircraft must follow when descending into Sea-Tac, directly influencing the noise experienced by communities surrounding the airport.

This November 2012 Federal Aviation Administration report evaluates the environmental impacts of proposed new arrival flight procedures at Seattle-Tacoma International Airport, part of the 'Greener Skies Over Seattle' initiative. It includes detailed appendices covering noise modeling, effects of aircraft noise on communities, historic and endangered species considerations, and agency coordination records. The goal of the proposed procedures was to reduce fuel consumption and emissions while assessing changes in noise exposure for surrounding neighborhoods.

ICAO good practice case study documenting the US/FAA NextGen ‘Greener Skies over Seattle’ initiative — a Final Environmental Assessment (FEA) completed November 1, 2012 for proposed PBN arrival procedures (STARs and RNP with Optimized Profile Descents) at Seattle-Tacoma International Airport (KSEA/Sea-Tac Airport). Collaborative project between FAA, Alaska Air Group (Alaska Airlines, Horizon Air), The Boeing

FAA Draft Environmental Assessment (EA), Volume 2 Appendices, for the Greener Skies Over Seattle project proposing new arrival procedures to Seattle-Tacoma International Airport (Sea-Tac Airport / KSEA), dated 31 October 2012. Appendices cover noise metrics (DNL, SEL, Leq, dBA), NIRS noise modeling technical report, aircraft operations and flight tracks, runway utilization, meteorological conditions, historic resource

In October 2012, the Federal Aviation Administration (FAA) approved new GPS-based arrival flight paths into Seattle-Tacoma International Airport (Sea-Tac) under the 'Greener Skies Over Seattle' initiative. The new procedures, developed in partnership with Alaska Airlines, Boeing, and the Port of Seattle, use satellite navigation technology to guide arriving aircraft on more precise, fuel-efficient descent paths from the northwest and southwest. The FAA concluded that the changes would not cause significant environmental harm, issuing a Finding of No Significant Impact (FONSI) alongside its formal approval.

FAA Safety Alert for Operators announcing the implementation of new wake turbulence separation categories (RECAT Phase I) at Memphis International Airport, effective November 1, 2012. The document details changes from the current 6-category system to a new system based on weight, approach speeds, and wing characteristics, with specific separation standards and aircraft assignments.
