7.1 Radar information and/or AIS information may
be transferred from systems compliant with the relevant standards
of the Organization. Other navigational information may be added to
the ECDIS display. However, it should not degrade the displayed SENC
information and it should be clearly distinguishable from the SENC
information.
7.2 It should be possible to remove the radar
information, AIS information and other navigational information by
single operator action.
7.3 ECDIS and added navigational information should
use a common reference system. If this is not the case, an indication
should be provided.
