Default Target Aquisition Help

Hey guys, trying to get into the sub portion of this game, but having a few difficulties. Got my TMA ok, its the acqusition with the towed array that keeps throwing me. Also got a Q on the visual sightings via periscope.

I know the contact gets mirrored, but how do I tell which is which? I know it says one will stay constant in a course turn and the other will move, but I see both move in varying degrees (via course change of 45-70 degrees) Where is the best place to view this change? The map? Long term display on the broadband (both seem to move here)?

When classifying multiple surface targets via the periscope, I cant seem to mark one contact. I mark one, photo, goto stadimeter and get range data. I then got back up, find a new target, mark it, photo, and stadimeter again, but it updates the original target! Maybe Im doing something wrong, I'll try it again. Seems like human error somewhere.

Anyway, TIA for some help.

With the Towed Array, simplest way is to wait. Once the towed array has stabilised (that's why both move), then one will still be in the same bearing that it was before the turn, whilst the other will be at a different bearing.

For example -

Sub heading 0, 2 contacts at 90 and 270 with the one at 90 the real one. Turning to 45, after sub and towed array have both stopped moving, there will still be one at 90, however the other one will now be at 0.

Hope this helps.

As for the periscope, I'm not sure.

The best procedure for the periscope is to photograph the contact (do not mark it yet), go into the stadimeter station to determine range and course and only then mark the contact.
At that point the information will be relayed to the tma station, with a bearing line whose length is equal to the range you've just determined.
If you mark the contact without using the stadimeter then all you'll get is a generic bearing line without any range information.
If you want to generate a secondo line of bearing after 2-3 minutes, rephotograph the same contact the go into the stadimeter etc...
If you want to generate a line of bearing for a second contact, put the new contact in the periscope, photograph it, and redo the same procedure as I have detailed above.
Remeber to mark the contact only after you've determined range and course.

You can see the change just about anywhere. You can mark both contacts and watch them on the NAV map, or see it on the BB or NB. Don't get confused by the real contact moving slightly--it won't move far and will return to its previous position in a matter of seconds. The false contact will change bearing--substantially and permanently--after the turn

The mirror contact should (eventualy) move twice the amount of degrees as the turn, also in the direction of the turn. That is a rule you can use to check. Give or take one or two degrees because of the bearing-drift before the turn.

But be carefull of making a turn that puts the contacts on the other side of the bow/TA axis. That can screw up the trackers, and/or confuse yourself.
