Verbal coordination must be accomplished prior to accepting control of a track indicating what?

Verbal coordination is an essential part of air traffic control that ensures safe and efficient management of aircraft. It involves communication between controllers to confirm who has responsibility for a specific flight or track.

In the context of this question, the correct answer focuses on the indicators that require specific coordination efforts before one controller can take over responsibility for a track. The terms provided—CST, DATA, OLD, or NONE—are related to control and tracking procedures where effective transmission of data and the status of the flight are crucial. By establishing verbal coordination involving these factors, controllers can ensure that they are fully aware of the current situation before accepting any control, thereby minimizing the risk of miscommunication and ensuring safety.

For example, CST usually refers to a certain status of the track, and understanding that before control is taken is essential. Likewise, DATA refers to any relevant information that needs to be shared to facilitate a seamless transition of control. Thus, recognizing and confirming these indicators via verbal coordination helps in maintaining situational awareness and operational continuity in radar control tasks.
