FAA Order JO 7110.126A, effective September 28, 2019, updates the rules air traffic controllers use to maintain safe distances between aircraft based on wake turbulence — the invisible air disturbances generated by planes in flight. The order introduces a nine-category system that groups aircraft by size and wake behavior, replacing older weight-only classifications, and reduces required separation distances in cases where science has shown greater spacing is unnecessary, such as when one heavy aircraft follows another of lower wake intensity. Facilities like Sea-Tac must obtain FAA authorization, train all personnel, and update their systems before applying these revised standards.

An Alaska Airlines Boeing 737 lifts off from Seattle-Tacoma International Airport (SEA-TAC), with the airport terminal, control tower, and Southwest Airlines aircraft visible in the background. Mount Rainier dominates the skyline behind the airport, a characteristic landmark visible from SEA-TAC under clear conditions.

A twin-engine widebody commercial jet, viewed from below and behind, is captured on final approach with all landing gear fully deployed. The aircraft features a red nose cone and red tail markings consistent with a major carrier livery, possibly American Airlines or a similar operator, but no registration or text is clearly legible.

Aerial photograph showing a large commercial airport with parallel runways, a control tower, and a cargo ramp area with purple-and-white livery aircraft consistent with FedEx or a similar cargo carrier. A body of water and forested hills are visible in the background, and a multi-lane highway runs along the western edge of the airport property.

Aerial photograph of Seattle-Tacoma International Airport (SEA/KSEA) in SeaTac, Washington, showing the main terminal complex, concourses with aircraft at gates, parallel runways, and surrounding urban areas. Puget Sound and the Seattle skyline are visible in the background, consistent with the airport's location between Seattle and Tacoma.

Beacon Hill Seattle Community Noise Team video link index documenting aircraft noise overflights recorded on August 13, 2018 at Beacon Hill, Seattle. Nine YouTube videos captured between 12:22 PM and 12:37 PM show aircraft flying overhead with simultaneous noise dosimeter readings displayed on screen. Still image from 12:22 PM shows a General brand noise dosimeter

A commercial passenger jet photographed from below against a partly cloudy blue sky, with a digitally overlaid concentric elliptical ripple graphic centered on the aircraft, likely illustrating sound wave or radar signal propagation. The airline livery is not clearly legible at this resolution.

A commercial passenger jet, appearing to be a narrow-body aircraft possibly in Alaska Airlines livery, is photographed from below against a partly cloudy blue sky. Concentric elliptical rings, representing aircraft noise or radar signal propagation, are digitally overlaid and centered on the aircraft, likely created for illustrative use in an aviation noise or airspace policy context.

A commercial passenger jet, possibly a United Airlines aircraft based on livery coloring, photographed from below against a blue sky with clouds. Concentric elliptical rings are digitally overlaid on the image, visually representing sound wave propagation or radar signal emanating from the aircraft — consistent with noise-impact or flight-tracking policy illustration.
