Inbound information must be forwarded to approach control when?

The correct answer emphasizes the importance of timely and accurate communication in air traffic control operations. Forwarding inbound information to approach control before the transfer of control point is crucial because it ensures that the receiving controller has all the necessary details about the aircraft's flight path, altitude, and other relevant information to provide safe and efficient traffic management. This step is vital for maintaining situational awareness and facilitating a smooth handoff as the aircraft transitions from one sector of airspace to another, ultimately contributing to overall flight safety.

Other options, while related to the aircraft's flight phases, do not align with the established protocols for information passing at the critical juncture of control transfer. This timing is essential for maintaining the flow of information and ensuring that all controllers have the latest status updates on aircraft operations as they navigate through controlled airspace.
