What indicates that a nearby aircraft is showing as proximity traffic on the display?

A filled white diamond on the display is used to indicate that a nearby aircraft is showing as proximity traffic. This visual representation signals to the pilot that there is an aircraft in the vicinity that may require attention, but it is not necessarily an immediate threat or in a conflicting flight path.

The use of different shapes and colors in the display system helps convey varying levels of urgency and potential risk. For example, a filled red triangle typically indicates an aircraft that poses an immediate threat, while blinking yellow circles represent a warning or alert status requiring situational awareness. A solid green square indicates friendly aircraft or those that are not a concern.

Understanding these visual cues is crucial for maintaining situational awareness and ensuring safe operations in the airspace.
