Which chart symbol denotes non-compulsory position reports?

• A. White Triangle
• B. Solid Black Triangle
• C. Circle with dot
• D. Red Diamond

Answer: (A)

On charts, symbols quickly tell you what ATC expects regarding your position reports. A white triangle is used to mark a point where you are not required to report your position—it's non-compulsory. This helps you know that you don’t have to call in at that fix unless ATC requests a report or you have information that would aid traffic management. The other symbols indicate different chart features or reporting requirements. A solid black triangle generally signals a point where a report is required, not optional. A circle with a dot is simply a navigation fix symbol, not specifically about reporting. A red diamond denotes another kind of special point or instruction, not a non-compulsory reporting point. So the white triangle uniquely identifies the non-compulsory reporting location.
