Simply, a plane comes into visual range, you lose the radar contact icon.
If your scope is up, usually you'll get a plane sighted message and basic range, short or long, etc..

Also, depending on the size and height of the plane, radar will differ when it picks the plane up.
Bigger planes will pick up at a much further range than smaller.

If you're not getting radar contacts with radar exposed out of visual range, I would say something in your mod setup is bugged.

You know, Dang!... I forgot about this. I've also forgotten if I've used the periscope when this "problem" occurs as I don't like to have more than one mast above when there's planes about. I did notice one time, that I had both the periscope and the SD mast raised at the same time and the map icon changed from a grey square to the red triangle and I could see the plane from the OB Scope but I didn't make the connection.
I'm sure this is probably the issue. Now that I understand this I can work around it and it has nothing to do with any mods which is a relief.
Thanks Skipper, you are the Man! What a relief...
PS: One more thing; I guess this also means I've got to be really careful about surfacing just because the SD contact has dissappeared. I'll be raising the scope from now on!!
