my opinions about ECDIS here!<br><br>Power Requirement is not distinguished much because we will face not only ECDIS failure in case of Black out. <br>Yes, we still need the paper charts while using ECDIS so as we still keep a Sextant onboard in GPS era. We may overcome this problem by broadband Internet which may be widely and commercially available onboard 2 or 3 years from now. At this time, Paper Charts may be kept at the Head Office for emergency
use while we are enjoying the paperless navigation system onboard. In case of 1 or 2 ECDIS failure, promptly downloaded electronic charts can be used as traditional paper charts.<br><br>rgds/sirius
