Which condition indicates that no Electronic Navigational Chart (ENC) is available?

• A. No ENC Available
• B. Larger Scale ENC Available
• C. Customized Display
• D. Route Planning Required

Answer: (A)

The indication that no Electronic Navigational Chart (ENC) is available is clearly represented by the condition stating "No ENC Available." This phrase directly communicates the absence of any ENC for the given area, which is essential for safe navigation. In an ECDIS system, when mariners attempt to access charts or plan routes, the system must convey whether the relevant ENCs are present. The clear communication of "No ENC Available" helps navigators understand that they cannot rely on electronic navigation charts for that specific region, prompting them to take necessary safety measures or use alternative navigation methods. In contrast, the other options describe different scenarios that do not directly indicate the unavailability of ENCs. For instance, "Larger Scale ENC Available" suggests that there are indeed ENCs present, albeit at a larger scale than what might currently be displayed. "Customized Display" refers to the personal settings of the chart presentation and does not pertain to the availability of charts themselves. Lastly, "Route Planning Required" implies that charts may be available but that the navigator needs to engage in route planning, which does not directly reflect the absence of ENCs. Thus, identifying clear indications of ENC availability is crucial for ensuring navigational safety and awareness while operating an ECDIS
