Which sector should utilize the procedure for transferring radar identification without verbal coordination?

The option indicating that the procedure for transferring radar identification without verbal coordination should be utilized by the first sector within the receiving facility is correct because this sector is responsible for the initial acceptance of the radar target. When a radar target enters a new sector, the first sector should be the one to establish radar identification automatically based on pre-agreed procedures. This method streamlines the transfer process and reduces the workload for both controllers, especially in busy airspace where quick and efficient communication is crucial.

The procedures often mandate that the first sector in the receiving facility should take the lead in processing incoming aircraft to ensure continuity and clarity in air traffic management. This helps maintain safety and efficiency in airspace operations while minimizing the chances of miscommunication that can occur with verbal coordination.

Other options, such as the last sector within the receiving facility, may not be involved in the initial acceptance of the aircraft, and therefore would not be the appropriate choice for initiating the transfer of radar identification without verbal coordination. Additionally, using any sector based on availability or the one with fewer aircraft may lead to complications or delays, contradicting the goal of efficiency that this procedure is designed to achieve.
