When electronic navigation fails, what is the purpose of Paper Charts?

• A. Requiring new electronic hardware
• B. Upgrading sensors
• C. Replacing electronic systems
• D. Proficiency and training in using paper charts

Answer: (D)

Back-up navigation relies on tools that don’t depend on power or electronics. Paper charts provide a ready reference for plotting position, planning courses, and maintaining situational awareness when electronic systems fail. They contain coastlines, depths, aids to navigation, and tidal information, allowing the crew to determine the ship’s position by dead reckoning or from bearings and landmarks. Proficiency in using paper charts ensures safe navigation during outages, which is why this option is the best choice. The other options focus on hardware or system changes, not on maintaining navigation capability when electronics are down.
