Question 689Navigation General

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.
