What is the purpose of a handoff in air traffic control?

The purpose of a handoff in air traffic control is fundamentally about transferring radar identification to another controller. This process is crucial for maintaining continuous and safe air traffic management as an aircraft moves between different sectors or airspace. When a controller hands off an aircraft, they ensure that the new controller is adequately informed of the aircraft's current status, including its position, altitude, and intentions.

This seamless transition between controllers allows for a coordinated effort in maintaining the aircraft’s safe flight path and managing air traffic effectively. During this transfer, communication is pivotal; the original controller updates the next controller, who then takes over responsibility for the aircraft. This ensures that the aircraft is continuously monitored and any changes or instructions can be communicated without gaps, enhancing overall air safety.

The other options do not encapsulate the function of a handoff. For instance, interrupting communication for emergencies does not relate to the handoff process itself; rather, it refers to a specific protocol during critical situations. Notifying an aircraft of a change in altitude involves communication concerning operational directives but is not the primary focus of a handoff. Lastly, while requesting information from another controller is a part of traffic management, it does not define the specific purpose of a handoff within air traffic control procedures
