White Triangle on a Low En Route Chart depicts what?

White Triangle on a Low En Route Chart depicts what?

• A. Non-Compulsory (Non Mandatory) Position Report
• B. Mandatory position report
• C. Course change
• D. Weather report

Answer: (A)

Inenroute charts, symbols for ATC reporting points show whether a position report is required. A white triangle marks a non-compulsory reporting point. That means you’re encouraged to report your position when you cross it, but you’re not legally obligated to do so. These points help ATC estimate traffic and manage sequencing, especially on busy routes. It’s not a weather report, and it doesn’t indicate a course change—the symbol simply conveys the optional nature of reporting at that point.
