How does the ECDIS manage discrepancies in navigational data?

• A. It raises an alarm without displaying details
• B. It recalibrates the system automatically
• C. It provides visual alerts without data substitution
• D. It displays the discrepancy of positions

Answer: (D)

The Electronic Chart Display and Information System (ECDIS) is designed to enhance maritime navigation through the integration and management of navigational data. When inconsistencies or discrepancies in navigational data, such as position or chart information, are detected, ECDIS provides a clear and comprehensive approach to informing the navigator. Displaying the discrepancy of positions helps the user understand the current state of navigational accuracy and safety by visually presenting any inconsistencies that may affect navigation. This allows the navigator to make informed decisions based on the displayed information, enhancing situational awareness and ensuring safer navigation. The other options do not reflect the primary function of ECDIS when managing discrepancies. For example, raising an alarm without details would not provide useful information to resolve the issue. Automatic recalibration of the system could lead to reliance on a potentially erroneous correction without understanding the underlying data discrepancies. Visual alerts without data substitution may not provide the necessary context for the navigator to assess the situation adequately. Thus, displaying the actual discrepancies is vital for effective navigation and risk management.
