Which term describes a physical or automated action to transfer radar identification only?

The term that describes a physical or automated action to transfer radar identification is "Point Out." This process involves informing another controller that a target is being transferred to their airspace and confirming that they can see the target's radar return on their scopes. It helps ensure situational awareness and continuity of monitoring for the aircraft involved without needing to re-establish radar identification.

"Point Out" is significant in air traffic control as it facilitates cooperation between controllers managing adjacent airspaces, allowing for a seamless transition of responsibilities for the aircraft. Through this process, communication is established, and the receiving controller is alerted to the presence of the aircraft so they can take any necessary actions.

In contrast, the other terms refer to different concepts. "Radar Transfer" typically refers more to the broader context of transferring control or responsibility for the target but doesn’t specifically highlight the identification aspect. "Identification Handoff" may imply a transition of responsibility but focuses more on clear identification rather than simply transferring the radar return. "Radar Clearance" relates to authorizing an aircraft for a particular action, such as a specific altitude or course, which is not solely about the transfer of identification.
