In air traffic control, during the position relief briefing, what does the relieving specialist indicate when stating that the verbal briefing may begin?

In air traffic control, when the relieving specialist states that the verbal briefing may begin, indicating "Preview" signals that they are ready to hear an overview of the current traffic situation and any pertinent information that needs to be communicated. This term denotes the start of an organized exchange of necessary operational details between the relieving and the relieved specialist.

The use of "Preview" emphasizes the importance of going over the essential information, ensuring that the relieving specialist fully understands the current air traffic conditions, any ongoing situations, and special instructions. Each of the other terms—such as starting, reviewing, or proceeding—does not convey the specific context of preparing for a detailed brief of the current position operations and may imply a less formal or less structured approach to the transition of responsibilities. The clarity and precision in communication during a position relief briefing are crucial for maintaining safety and efficiency in air traffic operations.
