Yeah, I'll just have to grin and bear it!
I follow you with the memory usage, but you lost me on "3,000 yard bearing compass". I don't have a clue as to what that is. Hmmm. Correction: Yes I do! I was watching one of your other tutorials and suddenly there you were explaining all about it. Thanks again, got it now.
But otherwise, I've been attempting to keep the weather and sea state in mind when we have aircraft approaching the 5-mile limit. If they're at the edge of the circle, where we'd normally just remain at radar depth, and the the weather's clear and the sea's nearly flat, we go ahead and dip down to periscope depth just to be sure. It's working fine so far, thanks to your tutorial
yesterday, trying to vacate Jap waters, we had so many a/c harassing us that it was easier to just pull the plug and stay submerged until nightfall. Then we made a night run out of that particular area while charging up the batteries. No problems after that.
