When using TX-97 or C-Map charts with ECDIS, must you use a paper chart for primary navigation?

• A. Yes
• B. No
• C. Only under certain conditions
• D. Depends on the vessel type

Answer: (A)

Using TX-97 or C-Map charts with ECDIS does indeed require the use of a paper chart for primary navigation, particularly when these types of charts are in play. This is rooted in the regulations and best practices established by maritime authorities to ensure navigational safety. The utilization of paper charts alongside ECDIS serves as a failsafe. In the event of an electronic failure or malfunction in the ECDIS, the paper chart can provide a reliable alternative to continue navigation safely. This is especially important since not all electronic navigation systems are fully self-redundant. Furthermore, the International Maritime Organization (IMO) guidelines stipulate that while ECDIS should be regarded as the primary means of navigation, mariners must maintain access to official paper charts as a backup. This requirement reflects the cautious approach to safety at sea, acknowledging potential technical limitations or failures associated with electronic systems. By having a paper chart available, navigators can ensure they are not entirely reliant on a single system, which can be critical in emergency situations or when electronic systems experience issues with updates or data integrity.
