Sophisticated navigation and safety features of ECDIS

 The Electronic Chart Display and Information System (ECDIS) provides several sophisticated navigation and safety features¹²³⁴:

1. Route Planning and Monitoring: ECDIS allows for automatic route planning and monitoring, which greatly eases the navigator’s workload¹.

2. Automatic ETA Computation: ECDIS can automatically compute the Estimated Time of Arrival (ETA) at various waypoints or the final destination¹.

3. ENC Updating: ECDIS can automatically update Electronic Navigational Charts (ENCs), ensuring that the most current navigational data is always used¹.

4. Continuous Data Recording: ECDIS provides continuous data recording for later analysis¹. This can be useful for reviewing navigational decisions and actions, and for training purposes¹.

5. Alarms and Indications: ECDIS has alarms and indications in place to indicate and highlight dangers¹. This can help prevent accidents and enhance the safety of navigation¹.

6. Safety Settings: ECDIS allows for the customization of safety settings, including the safety contour, safety depth, shallow contour, and deep water contour². These settings control how the ECDIS presents depth information, making it easier to visualize areas of water that are safe for the vessel to navigate in from those which are not².

7. Integration with Other Systems: ECDIS can be integrated with other navigational equipment such as the Automatic Identification System (AIS), Automatic Radar Plotting Aid (ARPA), etc¹. This provides a comprehensive picture of the ship’s surroundings and its position¹.

These features greatly enhance navigational safety and ease the navigator’s workload, making ECDIS an essential tool for modern maritime navigation¹²³⁴.
