  • Enabling the ECDIS to respond to a safety depth contour based on vessel's actual draft,
  • Look-ahead functions which enable dangers or hazards to be identified automatically and warnings and alarms raised,
  • Provision of alerts and prompts for planned course alterations. The ability to customise the display and level of detail to suit the vessel, conditions and time of day.


Approximately 850 ENC are included in the AusENC service.
