What is the term for the transfer of separation responsibility from one controller to another?

The term for the transfer of separation responsibility from one controller to another is known as "Transfer of control." This process is crucial in air traffic management, as it ensures that aircraft are safe and properly guided as they transition from one controller’s airspace to another’s. During this transfer, the first controller relinquishes responsibility, and the subsequent controller assumes that responsibility, which typically involves a clear communication of the aircraft’s intentions and current status.

The other terms like "Changeover," "Separation handoff," and "Controller transition" may seem related, but they are not the formal terminology used within air traffic control contexts. "Changeover" might refer to a performance shift but does not specifically address the transfer of separation responsibilities. "Separation handoff" suggests a similar concept but is not the agreed term within standard aviation practice. "Controller transition" may refer to the idea of a transition occurring but lacks the specificity regarding the responsibility for aircraft separation and control that "Transfer of control" succinctly provides.
