AIS can be used as an aid to collision avoidance by providing real-time information about the position, course, speed, and heading of other vessels in the vicinity. This information can help ships to avoid potential collisions by enabling them to take timely and appropriate action, such as altering course or speed.
The AIS system can also provide alerts when vessels are on a collision course, allowing the officer on watch to take corrective action. However, it is important to note that AIS is only one of several tools that should be used for collision avoidance, and should not be relied upon exclusively.
Visual and radar observations, as well as radio communication with other vessels, are also important components of a comprehensive collision avoidance strategy.
