A crew going in-service for any reason should be transferred to whom?

When a crew goes in-service for any reason, transferring them to Tier 1 (OCC) is the appropriate action. The Operations Control Center (OCC) is responsible for overseeing flight operations and ensuring that all necessary logistical and operational support is provided to the crew. This includes managing flight schedules, monitoring operational status, and facilitating any coordination needed with other agencies or operational elements before the crew begins their duties.

Transferring the crew directly to the OCC allows for seamless communication and support, which can be critical in ensuring the safety and efficiency of their operations. The OCC plays a vital role in managing the flight's readiness, addressing any last-minute changes, and ensuring that all protocols are followed before the crew engages in their mission.

In contrast, other options do not serve the immediate operational and logistical role of transferring a crew into active duties. Flight Control generally focuses on in-flight operations, Air Traffic Control deals with the management of airspace and flight paths, and the Safety Management Team typically handles safety oversight and risk assessment rather than the active deployment of flight crews.
