What is the term used for the transfer of separation responsibility between air traffic controllers?

The term used for the transfer of separation responsibility between air traffic controllers is "Transfer of Control." This term specifically refers to the point at which one air traffic controller relinquishes control of an aircraft to another, thereby transferring the responsibility for providing air traffic services and separation from other aircraft. This process is crucial for maintaining safe and efficient air navigation, as it ensures that there is a clear and standardized procedure for which controller is in charge of an aircraft as it moves from one airspace sector to another.

When a controller transfers control, it involves a confirmation that the receiving controller has all the pertinent information about the aircraft, including its intentions, altitude, and any traffic advisories. This formalized exchange maintains the safety of air traffic management and helps prevent potential conflicts between aircraft.

In contrast, the other options relate to different concepts in air traffic management. For example, "Transfer of Authority" refers to delegating decision-making power but does not specifically address separation responsibility. "Transfer of Service" may imply the switching of responsibilities for different services, but it lacks the specificity needed to define the transfer of separation responsibility. "Transfer of Jurisdiction" typically involves broader oversight or control within regulatory domains rather than the direct separation responsibilities for aircraft.
