When is the coast track position symbol used in tracking?

The coast track position symbol is specifically utilized when contact with a radar target is lost. This symbol helps air traffic controllers maintain situational awareness by indicating the last known position of an aircraft that can no longer be tracked by radar. It plays a crucial role in ensuring that controllers can manage air traffic safely and effectively, particularly when dealing with potential unknowns in air traffic situations.

This use is critical as it allows controllers to continue monitoring the position of aircraft even when real-time radar data is unavailable, aiding in maintaining safety in airspace management. Other situations, such as routine traffic control monitoring or successful landings, typically rely on continuous radar contact, making the coast track position symbol less relevant in those contexts.
