This July 2016 Federal Aviation Administration Letter of Agreement establishes coordination and control procedures between Seattle Terminal Radar Approach Control (TRACON) and Seattle Airport Traffic Control Tower, replacing a prior agreement from June 2013. It outlines responsibilities for managing air traffic, including pre-arranged coordination protocols, handling of Boeing Field arrivals and departures, and conditions under which those procedures may be suspended. The document governs how controllers at both facilities communicate and share airspace authority around the Seattle area.

A federal appeals court denied a challenge by the cities of Mukilteo and Edmonds, Washington, along with local residents and advocacy groups, to the FAA's decision to open Paine Field near Everett to commercial passenger service without requiring a full Environmental Impact Statement. The court ruled that the FAA's environmental review process was conducted in good faith and was not arbitrary or capricious, finding that the agency properly assessed foreseeable noise and environmental impacts under the National Environmental Policy Act.

FAA Order JO 7110.659C, effective February 29, 2016, updates air traffic control procedures for Wake Turbulence Recategorization (Recat), which changes how aircraft are grouped for safe separation purposes. Instead of the traditional three weight classes (heavy, large, and small), Recat introduces six categories based on wingspan, takeoff weight, and an aircraft's ability to withstand wake turbulence, allowing for more precise separation distances and improved airport efficiency. Facilities must obtain authorization, train personnel, and submit weekly wake encounter reports for the first eight weeks after implementing these new procedures.

This February 2016 document contains FAA responses to noise complaints from Federal Way residents affected by Sea-Tac Airport flight operations. The FAA explains why departures are concentrated to the south 65% of the time due to wind and runway configuration, why flight paths cannot simply be rerouted or 'fanned out' to spread noise across neighborhoods, and why aircraft may appear lower than in the past despite following all published procedures. Any proposed changes to flight routes or procedures must be submitted through the FAA Instrument Flight Procedure (IFP) Gateway for safety, feasibility, and environmental review.

This 2016 report by Palo Alto resident Mark Shull examines how the FAA's NextGen 'Optimization of Airspace and Procedures in the Metroplex' (OAPM) program, implemented between 2012 and 2015, led to dramatically increased aircraft noise over residential communities by redesigning flight paths to be lower, straighter, and more concentrated. The author argues that while the program was publicly marketed as improving efficiency, reducing fuel use, and lowering environmental impact, its primary purpose was increasing airport capacity by reducing separation between aircraft and simplifying flight corridors. The report traces the legislative, regulatory, and industry decisions that shaped the program, concluding that communities were left worse off and that genuine air traffic modernization will be harder to achieve going forward.
