What happens when there is a discrepancy between continuous positioning systems and manual observations in ECDIS?

• A. It ignores the manual observations
• B. It resets the position to the last known fix
• C. It displays the discrepancy of positions
• D. It alerts the crew without displaying any data

Answer: (C)

When there is a discrepancy between continuous positioning systems and manual observations in ECDIS, the system displays the discrepancy of positions. This function is crucial for maintaining situational awareness and navigational safety. By showcasing the difference between the two data sources, the crew can assess the reliability of the positioning information and make informed decisions regarding navigation. The display of discrepancies helps identify potential errors in either the manual observations or the continuous positioning systems, enabling the crew to investigate further and take necessary corrective actions. This visibility enhances the decision-making process, promoting safer navigation by allowing for adjustments based on accurate and reliable data. Other responses do not provide the same level of situational awareness. Ignoring manual observations would be unsafe, as they could provide critical insights into navigational conditions. Resetting the position to the last known fix could lead to inaccuracies if the current position is significantly different, which would compromise navigational safety. An alert without displaying any data would not effectively communicate the extent of the discrepancy, rendering it less useful for navigation purposes.
