A-Scope radar

Arclight, you may have said it, but part was in code and I got confused and off track. "AFAIK"? Is that an official abbreviation, Navy jargon, Subsim code, or, pardon my french, the true language of love -"Pig Laitin?"

Anyway, I need an explanation worthy of a dummy.

AFAIK is Internet-speak for "as far as I know."

Fair enough.

I rushed the reply a bit, so I'm not surprised I didn't get my explanation across.

Code (Internet Speak) + my IQ (low) = confusion will always reign.

My one complaint about the radar is how it always stops sweeping when I go to that screen. Drives me nuts even though it's just a simple matter of clicking the switch to restart the sweep, LOL.

Anyway, my routine is as follows;

Once I get a 'blip' on the right-hand screen I usually turn the boat in that direction so that the 'blip' is top-center on the screen. This way I can usually tell in a short period of time which direction the target is moving (but not always).

I'll let the sweep come around and then freeze it on the target. The I'll check the left-hand radar screen to see the range.

I'll turn sweep back on and leave it on as I manoeuvre into a decent range with periodic checks of the left-hand screen for specific range. Once I feel I'm getting into visual then I'll get on deck and start using the Mark-1 Eyeball (along with my usually eagle-eyed crew who normally spot the bugger first anyway).

Hope this helps.

Each of you has taught me something. Thanks.

Here's the links to SH4 and radar type/use.

The SD air search radar is an AI function only and that is where your crew announcement came from. The SJ surface search set is both of the scopes you can man, and only becomes functional as the war progresses, and your sub actually has it installed. Yes, that is a bit confusing and to top it off, the buttons are/were mislabeled. The SJ A-scope is the green one with the horizontal grass line. It's used for range finding and has to be directed at the target to see the pips. The PPI (plan position indicator) is the red one with the sweeping clock like hand. This is a newer scope added to the sets and gives you a map, or plan view, showing bearing and range.

So, when the crewman says he has a radar contact, it's likely an aircraft. Look on your map view for a very fast contact and dive to evade.

This one describes the types in general with specs.

This one shows more theory and indicates the SJ A-scope was for accurate range finding.

The Cobia link has photo's of the actual set, but I don't see any graticules other than bearing ones on the PPI.
