Which statement about AIS is correct?

• A. AIS can replace radar systems
• B. AIS provides information about all vessels in the area
• C. AIS operates independently of other systems
• D. AIS accuracy depends on the transmitted data

Answer: (D)

The statement regarding the accuracy of AIS (Automatic Identification System) is correct because the reliability of information provided by AIS is heavily reliant on the quality and accuracy of the data that is transmitted. AIS depends on vessels broadcasting their own data, such as position, course, speed, and other navigational details. If this transmitted information is incorrect or corrupted, the accuracy of the AIS display will also suffer. Therefore, any issues with the input data directly affect the effectiveness and reliability of the system. The other statements present misconceptions about AIS. For instance, it does not replace radar systems as they serve different purposes and have distinct functionalities that complement each other. Furthermore, AIS does not provide information on all vessels in an area; it is limited to vessels that are equipped with and actively transmitting AIS data. Finally, AIS does not operate independently; it requires integration with various systems, such as VTS (Vessel Traffic Services) and ECDIS, to be fully effective.
