How is ECDIS used in planning a passage?

Passage planning with electronic navigating systems is no different, except that over reliance on the systems could take away the basic seamanship aspects of the mariner and non performance of any of the instruments may lead to confusion.

Electronic Display and Information System (ECDIS) can be of Raster Chart Display Systems (RCDS) displaying Raster navigational charts (RNC), which can be used in conjunction, with paper charts.

When passage planning uses ECDIS, it is prudent for the navigator to draw a Safety Contour around the ship. Crossing the safety contour e.g. shallow water, prohibited zone or a traffic separation scheme will be automatically indicated by the ECDIS.
