Solid black triangle indicating compulsory position reports appears on which chart type?

• A. Low En Route Chart
• B. High Altitude Chart
• C. Sectional Chart
• D. IFR Approach Plate

Answer: (A)

When flying IFR, you’ll encounter points along an airway where you must report your position to ATC. On low en route charts, these compulsory reporting points are marked with a solid black triangle. This symbol helps you quickly identify where a report is required while you’re navigating the route. It isn’t used on VFR sectional charts, which are for visual navigation and terrain features, nor on IFR approach plates, which show procedures for approaches rather than en-route reporting points. High altitude en route charts have their own symbols for various fixes and reporting, but the solid black triangle specifically indicating compulsory position reports appears on the low en route chart.
