Solid Black Triangle on a Low En Route Chart depicts what?

• A. Compulsory (Mandatory) position report
• B. Non-Compulsory position report
• C. NAVAID outage
• D. Altitude minimums

Answer: (A)

A solid black triangle marks a compulsory (mandatory) position report point. When you reach or cross that point, you are required to report your position to ATC, including details like your time and altitude, so ATC can maintain accurate traffic awareness along the airway or route. The solid fill distinguishes it from points that are not mandatory to report. Other chart features, such as NAVAID outages or altitude minimums, are shown with different symbols and wouldn’t be identified by this solid triangle.
