Who is responsible for separation when KVKS and 0M8 departures file over SQS while KGWO inbound on approach?

• A. Student
• B. ATC supervisor
• C. R-side
• D. GWO tower

Answer: (C)

Radarside control is responsible for maintaining separation when traffic from different streams shares the same radar-coverage airspace, such as departures filing over a fix and an inbound on approach. In this scenario, KVKS and 0M8 are departures crossing the same airspace that KGWO is using on final approach. The radar position must monitor all three tracks, manage sequencing, and ensure safe lateral/vertical separation as they pass through the same airspace. The tower would handle more localized airport operations, but the ongoing separation in this mixed approach/departure environment falls to the radar-side controller. The supervisor or a student would not perform the continuous separation duties in real time. Thus, the R-side is responsible.
