The AIS true scale symbol is used on what ranges on radar and which scales with the electronic chart?

• A. High ranges and small scales
• B. Normal ranges and medium scales
• C. Low (short) ranges and large scales
• D. Medium ranges and variable scales

Answer: (C)

The AIS true scale symbol is utilized at low (short) ranges on radar and large scales with electronic charts. This is important because the true scale symbol represents the actual size of the vessel as it would appear on the electronic display. At low ranges, the radar provides a more focused view of nearby vessels, and large scale charts facilitate a detailed depiction of significant navigational elements, including the true size of vessels represented by the AIS symbol. Using the true scale symbol effectively aids in accurate situational awareness for navigators, allowing them to assess proximity, size, and potential interactions with other vessels in real time. This is crucial for safe navigation, especially in congested waters where close quarters with other ships need immediate attention. In contrast, other range and scale combinations would not accurately reflect vessel sizes or positions, potentially leading to misjudgments in navigational decisions. Therefore, the correct answer emphasizes the connection between the operational capabilities of radar and electronic charts in providing crucial navigational information.
