VATSIM representation

The Seattle ARTCC is represented on the VATSIM network by the VATSIM Seattle ARTCC. The VATSIM Seattle ARTCC performs mostly the same functions as the real Seattle ARTCC, but for the VATSIM flight simulation network. The VATSIM Seattle ARTCC thus works to ensure the separation of flight simulator aircraft piloted by flight enthusiasts from around the world. However, unlike its real-world counterpart, the VATSIM Seattle ARTCC takes direct responsibility for staffing and manning all ATC facilities under its control, including terminal control centers for Class B, C, and D airspace such as at the SeaTac and Portland airports.
