When the ECDIS operates in RCDS mode, what is required?

• A. It requires electronic charts only
• B. It requires continuous GPS tracking
• C. It must be used with paper charts
• D. It requires higher power consumption

Answer: (C)

When the ECDIS operates in RCDS (Raster Chart Display System) mode, it is essential to utilize paper charts alongside electronic charts. RCDS is designed to display raster charts, which are essentially scanned images of paper nautical charts. The key requirement in this mode is the integration of these paper charts into the navigation process to ensure comprehensive situational awareness and safety. Using paper charts in conjunction with the electronic display under RCDS mode allows for cross-referencing, enhancing the navigator's ability to confirm navigation information, especially in situations where electronic charts might be incomplete or unavailable. The reliance on this combined methodology aligns with traditional navigation practices where paper charts were primarily used, thus providing an essential backup system and an additional layer of verification in the navigation process. This requirement ensures that mariners maintain compliance with convention regulations that often mandate the availability of official paper charts while using electronic systems. Such a practice is crucial for safety and effective navigation, particularly in challenging situations or areas where electronic data might be questioned.
