An alarm is generated at most every 2 minutes. Internal GPS Alarm (Only SEA iq Pilot) : Generate an alarm if the internal GPS position has not been received in 30 seconds or has a horizontal position error of at least 25m.This may result in more accurate display of location (especially when moving slowly), at the cost of increased battery use. When this option is enabled, these minimum thresholds are not used. : Normal behavior when using IOS location services is to only display updates when the vessel has moved at least 5m and/or heading has changed at least 5°. This feature is intended as an aid and is not a substitute for careful analysis of a route for safety. You can select a menu item to jump to the location of the feature in question. The list of problems is cut off at 100 maximum items. The feature that were detected as a possible problem are listed in approximate order based on position along the route. Results can also be viewed in tabular format by selecting the sub-menu. In those cases, you can zoom in further until they are displayed or you can turn off SCAMIN in Settings / Vector / Charts / Advanced. Sometimes Scale-Minimum (SCAMIN) attributes on features may prevent display of features (such as soundings). The most detailed chart information for each area is used for the analysis: when not zoomed into the most detailed chart, the features of the lower scale charts may not match those of the more detailed charts and in many cases features such as soundings may not be available. The results are presented graphicly on the chart display, with potentially unsafe areas marked in red. The current tidal offset is incorporated into the analysis.Īnalyzing the charts can be processing-intensive and you may experience lagging behavior, especially on older devices. When determining which items to highlight, the Safety Contour is used for Depth Areas and Depth Contours. Raster charts and non-ENC overlays (such as Autocad DXF, Shapefiles, XYZ, and GML data) are not considered when checking safe-water. For areas where bENCs are used, only features in the bENCs are included in the analysis (none from ENCs in the overlapping areas). Any areas that overlap only use data from the bENC. When Bathymetric ENCs are in use, they are used in preference to ENCs. Only ENCs with scale at least 1:100,000 are used for calculation of safe water. This feature is intended as an aid and is not a substitute for careful monitoring of Own-Ship's course.Ĭheck Route for Obstructions (Only SEA iq Pilot) : When enabled, charts are analyzed for dangers with the active route. When executing turning maneuvers, there may be small areas at edge of Own-Ship's swept path that are not included in the monitoring for safe water. You may notice there is a small lag before unsafe areas are updated. Safety scans are calculated periodically, every 5 seconds. Areas in predicted path identified as potentially unsafe water are outlined in red. When areas are detected in predicted path, an alarm generated at most once every 2 minutes. Raster charts and non-ENC overlays (such as Autocad DXF, Shapefile, XYZ, and GML data) are not considered when checking safe-water. Any areas that overlap only use data from the bENC.Īt most 12 minutes of predicted course are monitored. Only ENCs with scale at least 1:30,000 are used for calculation of safe water. If Vessel Buffer is enabled, the buffer area is added to the size of the safe area. Monitor Safe Water (Only SEA iq Pilot) : When enabled, the predicted swept-path of Own-Ship is monitored for any depth areas (or dredged areas) that are shoaler than then Safety Contour setting. This is the opposite of Transit mode (aside from Straight Course Vector, Follow Offset, and True-Scale Prediction) Turning this on has the same effect as making the following changes. This is the opposite of Maneuver mode (aside from Straight Course Vector, Follow Offset, and True-Scale Prediction).Ĭlose Maneuver Mode (Only SEA iq Pilot) : Enable Maneuver mode. Transit Mode (Only SEA iq Pilot) : Enable Transit mode. Any items listed here may be changed or removed in future Should not be used without first carefully reading the documentationīelow. The settings listed here are not used by the typical user.
