According to IMO Performance Standards, which sensors must ECDIS monitor for alarm activation if input is lost?

• A. Temperature, Pressure, and Wind
• B. Position, Speed, and Heading
• C. Current, Depth, and Visibility
• D. Course, Distance, and Time

Answer: (B)

The correct response is based on the requirement set forth by the International Maritime Organization (IMO) Performance Standards for ECDIS. ECDIS must continuously monitor critical navigation data, which includes position, speed, and heading. These parameters are essential for ensuring safe navigation and effective route planning. Position is vital for determining the vessel's current location relative to navigational hazards and intended routes, speed is necessary for calculating time to destination and assessing collision risks, and heading is crucial for maintaining course and avoiding unintended deviations. If there is a loss of input from these sensors, it could significantly impact navigational safety, potentially leading to groundings or collisions. Therefore, the ECDIS is programmed to activate alarms if it detects any discrepancies or failures in these critical data inputs, allowing the mariner to take immediate corrective actions. The other choices list various parameters that, while important in navigation and environmental monitoring, are not central to the immediate functionality required for safe navigation indicated by the IMO standards.
