What does "Preview" indicate during the position relief briefing process?

"Preview" during the position relief briefing process indicates an "Indication to Begin Briefing." This term is used to signal that the outgoing controller is ready to start the briefing, and it marks the transition from the current duties to the discussion of the necessary information that the incoming controller will need. The word "preview" suggests that the outgoing controller will provide an overview of the situation, key points, and any important updates that may affect the incoming controller's operations. This is a crucial part of ensuring a smooth handoff of responsibilities, allowing for continuity and safety in air traffic control operations.

In this context, the other options do not align with the specific role of "preview" in this process. For example, while the start of new responsibilities and preparation phase might be conceptually related to the briefing itself, they do not accurately describe what "preview" signals. Similarly, the end of current duties does not encompass the intent behind using the term "preview," as it primarily serves as a prompt for the briefing to commence rather than a declaration of responsibility change.
