If an aircraft is out of lateral tolerance, what status will it change to?

When an aircraft is out of lateral tolerance, its status changes to "Free track." This status indicates that the radar system is no longer able to maintain a precise track of the aircraft, likely due to the aircraft deviating from its expected flight path or moving beyond the radar system's processing capabilities. In "Free track" mode, the system continues to display the last known position of the aircraft, but it doesn’t receive updated positional data, which means the radar has lost reliable control over that specific track.

This status helps controllers recognize that they should continue monitoring the situation but may not have accurate information about the aircraft's current lateral position or trajectory. Understanding the implications of this status is vital for maintaining safety and ensuring proper communication with the aircraft, allowing controllers to take necessary actions or provide updates to the pilot as required.
