Question 689Navigation General70% to pass

While underway vessels equipped with an automatic identification system (AIS) are required to transmit specific information at varying intervals. What information contained in a class A unit broadcast is only required to be transmitted every six minutes?

AI Explanation
The correct answer is D) the name of the vessel. According to the regulations governing Automatic Identification System (AIS) equipment, class A units are required to transmit certain information at varying intervals. While most data, such as the navigational status, rate of turn, and vessel's heading, must be updated and transmitted every few seconds, the vessel's name is only required to be transmitted every six minutes. The other answer choices are incorrect because the navigational status, rate of turn, and vessel's heading are all data that must be transmitted more frequently than every six minutes by a class A AIS unit.
