Thks Kumando I was just about to give the same info...
The charts giving the kms distance from speed/time are located in GWX on the map screen top left.
4 charts there : General map with convoy routes, maps of friendly bases showing subnets and minefields, then the 2 distance charts (Seite 1 and Seite 2)
Personnally I find it faster to use a pocket calculator than to slide out the charts, as you often have to compute hours and minutes...
I only used the echolot like I would have done IRL to confirm my estimated position.
PS : I left the initial zoom at 500. I found the link to download the transparent file on a thread in this forum, should still be there. Otherwise can mail it to interested people.
ADVICE TO ALL KALEUNS IN THE MED :
If for some reason you have to make a stop in Lampedusa, plse note there is a huge subnet across most of the harbour. Do not try to head directly in the harbour from the south, the two free channels are located near the lighthouses East and West of the entrance. Depending from which side you come, plan a route to the nearest lighthouse and stay close to come in...
I just discovered this the hard way going out (fortunately was going slow so not much damage) I didn't notice in coming in, because of the night and the heavy fog I went straight for the lighthouse...
