20.5 Alerts Generated by Radar
Alerts generated by Navigation Calculation and Chart Calculation are common for each workstation (i.e. they can be
seen on each workstation’s alert queue with same alert number). Alerts generated by Radar overlay are generated
locally on workstation where failure happens (i.e. they can only be seen on workstation where it happens). Each
workstation has own alert numbers for alerts generated by radar overlay.
Alert range is: Alert 100 - Alert 111, for Chart radar number 1.
Alert range is: Alert 200 - Alert 211, for Chart radar number 2.
Alert range is: Alert 150 - Alert 161, for Chart radar number 3
Alert range is: Alert 250 - Alert 261, for Chart radar number 4
For example: "100 RadOv No Headline" for Chart radar 1 "200 RadOv No Headline" for Chart radar 2
Alerts which are generated by radar being source of Radar overlay and/or tracked targets are as follows:
Alert range is: Alert 112- alert 119, for radar antenna 1
Alert range is: Alert 212- alert 219, for radar antenna 2
Alert range is: Alert 162- alert 169, for radar antenna 3
Alert range is: Alert 262- alert 269, for radar antenna 4
For example: " 112: TT dangerous target" for radar antenna 1 " 212: TT dangerous target" for radar antenna 2
