As an aircraft progresses along its route, to whom is data forwarded?

When an aircraft is actively progressing along its route, the data is typically forwarded to a controller within the same facility first. This practice ensures that the current controller can maintain situational awareness of the aircraft's position and trajectory. The controller will then relay the pertinent information to the receiving facility, which is responsible for the next phase of air traffic management.

This process is crucial for maintaining continuity of instructions and information transfer, ensuring safety and efficiency as the aircraft navigates from one airspace sector to another. By involving the controller in the same facility prior to forwarding the information, it allows for any immediate clarifications or updates to be made before passing the data along, thereby enhancing overall communication within the air traffic control system.
