I agree with Shortstripper, I have the same system. I also don't believe anyone with a brain would suggest that steam driven DR should be allowed to die, any more than basic stick & rudder skills should be replaced with "goto" & "autoland" With a power failure the other day resulting in "No Signal" (position 56deg 18 N--4deg 15 W heading 290M) the line on the map becomes a necessary back up. An object lesson in not relying on it. Nice lunch at Oban by the way & the weather was perfect.
