Question

If the electronic chart is part of an ECDIS, it must display the minimum data required by IMO/IHO, to include all of the following EXCEPT____________.

A) hydrography
B) aids to navigation
C) regulatory boundaries
D) tidal currents

Answer 1

An ECDIS is used for navigation at sea and displays electronic charts that must meet minimum data requirements. The data displayed includes hydrography, aids to navigation, and regulatory boundaries.

Step-by-step explanation:

An ECDIS (Electronic Chart Display and Information System) is used for navigation at sea. It displays electronic charts that must meet the minimum data required by IMO/IHO (International Maritime Organization/International Hydrographic Organization).

The data that must be displayed includes hydrography (information about the depth, contours, and nature of the seabed), aids to navigation (such as lighthouses and buoys), and regulatory boundaries (such as exclusive economic zones and traffic separation schemes).

However, tidal currents are not required to be displayed on the electronic chart as part of an ECDIS.
