Charts and 3D Chart Views Automatic Identification System The Automatic Identification System (AIS) enables you to identify and track other vessels. About AIS AIS alerts you to area traffic. When connected to an external AIS device, the chartplotter can show some AIS information about other vessels that are within range, that are equipped with a transponder, and that are actively transmitting AIS information. The information reported for each vessel includes the Maritime Mobile Service Identity (MMSI), the location, the GPS speed, the GPS heading, the time that has elapsed since the last position of the vessel was reported, the nearest approach, and the time to the nearest approach.

If the safe-zone collision alarm has been set to Off, the target flashes, but the audible alarm does not sound and the alarm banner does not appear (page 18). If the AIS transmission from the vessel is lost, a message banner appears. The location of this symbol indicates the closest point of approach to a dangerous target, and the numbers near the symbol indicate the time to the closest point of approach to that target. Dangerous target has been lost. A red X indicates that the AIS transmission from the vessel has been lost, and the chartplotter displays a message banner asking whether the vessel should continue to be tracked.
