When ATC verifies that you are in radar contact, who is primarily responsible for VFR aircraft separation?

In the context of VFR (Visual Flight Rules) operations, when ATC (Air Traffic Control) verifies that you are in radar contact, the responsibility for maintaining separation from other VFR aircraft primarily falls to the pilot in command. This is based on the principle of "see and avoid," which is central to VFR flight.

Pilots are expected to maintain visual awareness of other aircraft in their vicinity, as they must actively look out for traffic and take appropriate measures to ensure their own separation. While ATC provides traffic advisories and can assist with separation for VFR flights under certain circumstances, the ultimate responsibility resides with the pilot. This is particularly evident in uncontrolled airspace or during times when ATC services are not directly providing traffic separation.

Ground Control, while an essential part of ATC, is primarily responsible for managing aircraft movement on the ground, not in the air. Fellow pilots also play a role in maintaining situational awareness; however, they do not have the official responsibility mandated for separation under VFR regulations.
