4. AIS OPERATION 4.11 Lost Target A target is declared a lost target when it fails to produce data for six minutes or five reporting intervals, whichever is the shorter. When this occurs, the target is marked with the (flashing) lost target symbol and the message "AIS TARGET LOST" appears in the Alert Box. To acknowledge a lost target, press the ALARM ACK key, or use the trackball to select the [ALERT] box then press the left button. 4.11.

. AIS OPERATION 4.13 AIS Collision Alarm (CPA, TCPA) This radar calculates CPA and TCPA by using own ship and relative target positions. An AIS dangerous target is one whose CPA and TCPA are within the range of the CPA and TCPA limits set in the TT/AIS box. The AIS symbol of an AIS dangerous target is red and flashing, and is announced with the Alert "AIS DANGER OF COLLISION". After the alert is acknowledged the target symbol is displayed in red color.

4. AIS OPERATION 4.14 How to Associate TT and AIS Targets An AIS-equipped ship is usually displayed by two symbols on the radar display. This is because the AIS ship position is measured by a GPS navigator (L/L) whereas the radar detects the same ship by PPI principle (range and bearing relative to own ship radar antenna). To avoid the presentation of two target symbols for the same physical target, use the “association” function.
PAGE 6
4. AIS OPERATION When the association criteria (gap, range, bearing, speed, and course) is met, and the ASSOCIATION TARGET setting is [AIS], the TT symbol is erased and only the AIS symbol is displayed. All default association settings are restored whenever the power is turned on. To show the association information, place the cursor on the target data box at the right side of the screen, then press the ACQ key. The selected target’s AIS and TT data are displayed together as shown in the examples below.

4. AIS OPERATION 4.16 How to Use AIS Messages You can transmit and receive messages via the AIS, to a specified destination (MMSI) or all ships in the area. Messages can be sent to warn of safety of navigation, for example, an iceberg sighted. Routine messages are also permitted. Short safety related messages are only an additional means to broadcast safety information. They do not remove the requirements of the GMDSS. 4.16.1 How to create and save messages Up to ten messages can be saved at any time.

5. PLOTTER OPERATION (IMO-TYPES) 5.4 Radar Map A radar map is a combination of map lines and symbols whereby the user can define and input the navigation data, route planning and monitoring data. The radar map can contain 20,000 points of data. Inscribed marks are retained when the power is turned off. The radar map is referenced to the WGS-84 datum and appears only when there is valid position data input. The radar map does not affect any radar functions.
