Question 865Navigation General70% to pass
Which of the following statements is TRUE regarding automatic identification systems (AIS)?
AI Explanation
The correct answer is B) AIS provides the other vessel's identity, dimensions and navigational status regardless of visibility.
This is correct because AIS is designed to automatically exchange information such as vessel identity, position, course, speed, and other data between equipped vessels and shore stations. This information is available regardless of visibility conditions, unlike relying solely on visual sightings or radar.
The other options are incorrect because: A) AIS is not designed to completely replace other collision avoidance methods, but to supplement them; C) AIS can provide information even when a vessel is obscured by radar clutter; and D) AIS should not be relied upon as the sole means to determine risk of collision, as it should be used in conjunction with other navigational tools and situational awareness.
