A yellow alert that is not relevant and must not be communicated to the Radar Controller is triggered by which scenario?

• A. It must be communicated to the Radar Controller anyway.
• B. Should be escalated to the supervisor.
• C. It is not relevant and must not be communicated to the Radar Controller.
• D. It requires immediate action by the pilot.

Answer: (C)

The main idea is that information shared with the Radar Controller should be relevant and actionable for their tasks. A yellow alert is a caution signal, but not every yellow alert affects radar operations or requires controller action. When the alert has no impact on controller responsibilities—no bearing on traffic separation, sequencing, or safety decisions—it should stay internal to the crew. Communicating non-relevant alerts would clutter the controller’s workload and risk misinterpretation, so the correct approach is to handle it without informing the Radar Controller. If the situation later becomes relevant, it can be communicated then. Immediate action by the pilot isn’t triggered by a non-relevant alert, and escalating to a supervisor isn’t needed unless there’s a policy or safety reason to reevaluate the alert’s relevance.
