6.0.7 Currents Prediction
The World Wide database with Tidal stream information is available with MAX C-CARDs.
When data/time is available, Tidal stream arrows are shown on the charts, indicating the
direction and strength of the Tide:
Figure 6.0.7 - Tidal stream arrows
If no data/time is available from the GPS or the CP590 is not in Simulation Mode, the icon
on the chart is generic one. The color of the arrow denotes the strength of the current as
follows:
