Which statement about compulsory vs non-compulsory points on an enrollee chart is true?

Which statement about compulsory vs non-compulsory points on an enrollee chart is true?

• A. Compulsory points require ATC contact
• B. Compulsory you must report to ATC; non-compulsory you don't have to
• C. Non-compulsory points require ATC contact
• D. Non-compulsory points never appear on charts

Answer: (B)

The key idea is how ATC communications are mandated at certain fixes on enroute charts. Compulsory reporting points are locations where you must establish two-way communication and provide a position report to ATC as you pass or reach the point. Non-compulsory points are just navigation fixes with no mandatory reporting requirement at that point; you only report there if ATC specifically requests it or you choose to provide additional information. So the correct statement emphasizes the obligation: compulsory points require you to report to ATC, while non-compulsory points do not require mandatory reporting. You may still report at non-compulsory points if ATC asks, but there’s no automatic obligation.
