Which of the following is NOT transmitted as part of dynamic data in AIS?

• A. Ship's heading
• B. Time of position
• C. Ship's name
• D. Position accuracy

Answer: (C)

Dynamic data in the Automatic Identification System (AIS) refers to information that changes frequently and is critical for navigation and situational awareness. This typically includes data related to the vessel's movement and navigation status, such as the ship's heading, position accuracy, and the time of the position report. The ship's name, while important for identification purposes, is considered static data because it does not change while the vessel is in operation; the name of a ship remains constant regardless of its navigational status or movements. Therefore, the ship's name does not fit into the category of dynamic data that is transmitted by AIS. When analyzing dynamic data, traffic monitoring and collision avoidance systems highly value real-time information like ship's heading and position accuracy due to their importance in providing a complete situational picture. The time of position is also vital, as it helps in understanding the vessel's current location relative to the time it was transmitted. Hence, the distinguishing factor here is the nature of the data being either dynamic with frequent changes or static with a constant value.
