Grounding Alarm : This function looks ahead of the vessels heading to see if a potential danger exists. When the Grounding Alarm is enabled the chartplotter will draw a triangle in front of the vessel on the chart page showing the area that is being searched as shown below. The depth and range (distance) of the area the chartplotter looks ahead for a shallow area can be set using this function.

The following warning appears when the Grounding Alarm is enabled:

NOTES

The Grounding Alarm function only operates with the new NT+ C-CARDs. It also affects the speed of the redraw of the screen. If this function is not used it may be disabled.

When any of the objects checked are found for the first time, the chartplotter shows a pop up window to alert the user of the possible danger. The name of each new dangerous object found is reported in the warning window. In the Grounding Alarm Report page the relative item has a tick marker next to it, to identify the dangerous object currently detected. If in the next search cycle the same objects are found again, the alarm window will not be shown. Instead, if in the next searches the objects found before are no longer detected, their relevant item in the Grounding Alarm Report page is cleared (note that in this case, if the same object type is found again later, the Alarm will be shown). The chartplotter shows an icon on the charts that identifies when a Grounding Alarm is detected.
