What is meant by a 'radar handoff' in ATC coordination?

In the context of Air Traffic Control coordination, a 'radar handoff' specifically refers to the process of transferring control of an aircraft from one controller to another. This is a crucial aspect of ATC operations, ensuring continuity in the management of an aircraft as it moves through different airspace sectors overseen by various controllers.

During a radar handoff, the first controller communicates vital information to the next controller, including the aircraft's current position, altitude, and any other relevant data necessary for safe operations. The goal is to maintain situational awareness and avoid any gaps in oversight that could compromise safety.

While informing the pilot of expected weather, advising of changes in landing priority, and tracking altitude are all important functions of air traffic control, they do not encapsulate the specific process of transferring an aircraft's control. Therefore, the focus on the transfer of responsibility distinguishes this action and highlights its significance in maintaining safe air traffic management.
