In EDST red alert handling, is it expected that Radar Controllers inform a student every time they stop an aircraft's climb or descent for conflicting traffic?

• A. No, not for normal and obvious altitude clearances that generate muted red alerts.
• B. Yes, always inform the student.
• C. Only when the student explicitly requests information.
• D. Only if the controller believes a conflict is imminent.

Answer: (A)

In EDST red alert handling, not every climb or descent stop to resolve conflicting traffic requires a verbal update to the student. When the situation is routine and obvious, the system uses muted red alerts, so the controller doesn’t need to narrate each altitude change. The student is expected to monitor the situation and respond to standard clearances without constant commentary. Verbal guidance is reserved for non-obvious situations or when the controller believes a directive or additional explanation would improve safety, such as when a conflict is imminent or unclear.
