Seattle Terminal Radar Approach Control (TRACON) (S46) is located between the Cascade and Olympic mountain ranges in the Pacific Northwest and supports approximately 4,800 square miles of airspace from the surface to 15,000ft. Encompassed within S46 boundaries are approximately 52 towered, non-towered, military and satellite/private airports. The primary airport supported by Seattle TRACON is Seattle Tacoma International Airport (SEA) and is one of the fastest growing airports within the National Airspace System (NAS). Major secondary airports served by S46 include, but are not limited to Boeing Field (BFI), Renton Airport (RNT) and Paine Field (PAE).

S46 is presented with many complexities and challenges throughout the year to include mountainous terrain, supporting multiple photogrammetric flight requests, aerial survey work, tactical military exercises, parachute operations and flight school training operations.

Air traffic traversing S46 airspace has grown tremendously over the past several years with an overall increase of approximately 32 percent from 2013 to 2018. This growth in traffic volume has uncovered some opportunities to improve processes and performance. Seattle TRACON is continually seeking to improve the service we provide to users of the NAS while maintaining the highest level of safety.
