Division 2.3.1.2 Navigational assistance service

A navigational assistance service informs the conning skipper on difficult navigational or meteorological circumstances or assists the conning skipper in case of defects or deficiencies. This service is normally rendered at the request of a vessel or by the VTS when deemed necessary.

To provide individual information to a conning skipper, the VTS operator needs an actual detailed traffic image.

The actual traffic information has to be exchanged continuously (every three seconds, almost real time or another predefined update rate set by the competent authority).

All other information has to be made available on request of the VTS operator or in special occasions.
