What does the symbol Diamond on radar indicate?

• A. A flat track
• B. A co-located aircraft
• C. A high-priority target
• D. An out-of-service track

Answer: (A)

On radar displays, each track symbol conveys the status of the tracked target. A diamond indicates a flat track, meaning the target’s altitude is not changing—the vertical rate is essentially zero or altitude data isn’t being reported. This helps you understand that the target is being tracked, but there’s no vertical movement information available. It’s not used to flag co-located aircraft, high-priority targets, or out-of-service tracks, which would be shown with different symbols or markers.
