According to SOLAS, what sensors must be connected to a Class A AIS unit for vessels over 50k GT?

• A. Speed indicator, GPS, and Depth sounder
• B. ROT indicator, EPFS (GPS), and Heading
• C. Radar, Echo sounder, and GPS
• D. Heading, Speed, and Wind direction

Answer: (B)

A Class A AIS (Automatic Identification System) unit, as outlined by the International Convention for the Safety of Life at Sea (SOLAS), requires specific data inputs to function effectively. The correct response identifies the essential sensors needed for the operation of this system on vessels exceeding 50,000 gross tonnage (GT). In particular, the unit must be connected to a Rate of Turn (ROT) indicator, an Electronic Position Fixing System (EPFS) such as GPS, and a heading sensor. The ROT indicator provides crucial data regarding the vessel's change in course over time, allowing for better situational awareness and navigation safety. The EPFS, often fulfilled by a GPS, is vital for determining the vessel's precise position. Lastly, the heading sensor communicates the vessel's orientation in relation to True North, further enhancing navigational accuracy. These components work together to ensure that the AIS transmits essential navigation information accurately, which is critical for collision avoidance and other maritime safety purposes. The combination of these specific sensors aligns with SOLAS requirements and emphasizes the importance of integrating reliable and real-time data into the AIS for optimal operation and safety. Other options do not satisfy the requirements set by SOLAS for Class A vessels, focusing on different sensor combinations that
