Don't quote me on this but I heard from some place years ago that unless you
are on an ocean, you are just mobile and not maritime mobile compared to
being on a lake or river for example. The same is true, I believe, with
aeronautical mobile. That means you are flying over an ocean. Otherwise,
flying over land, you are just air mobile or mobile period. I don't know
this for certain but I think the great lakes are calculated in miles instead
of nauts because they technically are not oceans. I'd be curious if any of
this old memory is true or not. I know rivers are measured and calculated
in miles instead of nauts but as soon as they empty into the oceans, it
changes to nauts instead of miles.
