Term
Know what happens if an ECDIS operator entered 12.5 meters as
their safety contour depth and the chart was configured using
5m, 10m, 15m, 20m, 30m, and 50m contour lines; what depth would
the ECDIS show the safety contour
,Give this one a try later!
It will choose the next highest; It will ignore the depth and use the
in this case 15m default setting
It will choose the next lowest; in this It will average the depths; in this
case 10m case 12m
Don't know?
