What is the term for the transfer of radar ID with the intent to transfer communications?

The term for the transfer of radar ID with the intent to transfer communications is known as a handoff. This process is crucial in air traffic control as it allows for the seamless transition of an aircraft from the jurisdiction of one air traffic controller to another, ensuring that continuous communication and tracking are maintained.

During a handoff, the controller provides the next controller with the necessary information, including the aircraft's position, altitude, and intentions, so that the subsequent controller can take over the responsibility for providing air traffic services to that aircraft. This step is essential for maintaining flight safety and efficiency, as it helps prevent gaps in communication that could lead to misunderstandings or safety risks.

In contrast, the other terms do not specifically refer to the transfer of radar ID along with communication transfer. Notification generally refers to informing the next controller of an aircraft's presence or status without implying an actual transfer of control. Identification relates more to the process of recognizing an aircraft on radar and associating it with its flight plan or squawk code. Control transfer, while it might sound relevant, is often used in a broader context and does not specifically denote the radar ID aspect connected with communication. Thus, the most accurate term in this context is handoff.
