Use the sliderbar to adjust the photo opacity. The higher you set thepercentage, the more the satellite photos cover both landand water.Automatic Identification SystemThe Automatic Identification System (AIS) enables you toidentify and track other vessels, and alerts you to area traffic.When connected to an external AIS device, the chartplotter canshow some AIS information about other vessels that are withinrange, that are equipped with a transponder, and that areactively transmitting AIS information. The information reportedfor each vessel includes the Maritime Mobile Service Identity(MMSI), location, GPS speed, GPS heading, time that haselapsed since the last position of the vessel was reported,nearest approach, and time to the nearest approach.AIS Targeting SymbolsSymbol DescriptionAIS vessel. The vessel is reporting AIS information. Thedirection in which the triangle is pointing indicates thedirection in which the AIS vessel is moving.Target is selected.Target is activated. The target appears larger on the chart. Agreen line attached to the target indicates the heading of thetarget. The MMSI, speed, and direction of the vessel appearbeneath the target, if the details setting has been set to Show.If the AIS transmission from the vessel is lost, a messagebanner appears.Target is lost. A green X indicates that the AIS transmissionfrom the vessel is lost, and the chartplotter displays amessage banner asking whether the vessel should continueto be tracked. If you discontinue vessel tracking, the losttarget symbol disappears from the chart or the 3D chart view.Dangerous target in range. The target flashes while an alarmsounds and a message banner appears. After the alarm hasbeen acknowledged, a solid red triangle with a red lineattached to it indicates the location and the heading of thetarget. If the safe-zone collision alarm has been set to Off, thetarget flashes, but the audible alarm does not sound and thealarm banner does not appear. If the AIS transmission fromthe vessel is lost, a message banner appears.Dangerous target is lost. A red X indicates that the AIStransmission from the vessel is lost, and the chartplotterdisplays a message banner asking whether the vessel shouldcontinue to be tracked. If you discontinue vessel tracking, thelost dangerous target symbol disappears from the chart or the3D chart view.The location of this symbol indicates the closest point ofapproach to a dangerous target, and the numbers near thesymbol indicate the time to the closest point of approach tothat target.Viewing a List of AIS ThreatsFrom a chart or 3D chart view, select MENU > OtherVessels > AIS/MARPA List.Heading and Projected Course of Activated AISTargetsWhen heading and course over ground information are providedby an activated AIS target, the heading of the target appears ona chart as a solid line attached to the AIS target symbol. Aheading line does not appear on a 3D chart view.The projected course of an activated AIS target appears as adashed line on a chart or a 3D chart view. The length of theprojected course line is based on the value of the projectedheading setting. If an activated AIS target is not transmittingspeed information, or if the vessel is not moving, a projectedcourse line does not appear. Changes in the speed, course overground, or rate of turn information transmitted by the vessel canimpact the calculation of the projected course line.When course over ground, heading, and rate of turn informationare provided by an activated AIS target, the projected course ofthe target is calculated based on the course over ground and therate of turn information. The direction in which the target isturning, which is also based on the rate of turn information, isindicated by the direction of the barb at the end of the headingline. The length of the barb does not change.4 Charts and 3D Chart Views
