AOB wheel discrepancy

[comet61]

Don't worry Nissum,
you haven't 'miss' any version of attack disc.there are some (minor) differences between the disc of Olc gui and the disc in the pics of manual but it is better to be the way that you see in-game.

the middle ring (compass) is indented to be stable and is better to be that way showing always up the North.

now ,you don't have to turn the compass to match our course at 180 of bearing.the bearing ring (outer ring) is moving automatically as we changing our course.i represent the example 2 in the following pic. setted the sub's course to 115 .when sub finally is moving to 115 you will notice that the outer ring had automatically moved to show 115 at the compass of attack disc (see marks ''1'')
so ,you skip the step of the manual that telling you to turn the compass

next,you set the target's course (we know it for the example 2)
turn the inner ring to show you 150 at the compass of attack disc
another reason that is better the way this disc does things is exactly this: the course of target as represented on the attack disc is exactly how it will look if you have drawen target's course on navmap(at navmap always North is up,too)
(see mark ''2'' for all these)

next you place the bearing ,the example is telling us that the target is at bearing 65 port,which means that the bearing is 360-65=295.now grap the edge of the bearing pointer (the one with the black arrow pointing to the outer ring)and place the arrow to show the 295 on bearing ring
(see mark ''3'')
read the AOB (look at the pic where the aob is showing)

about the vorhalt 'missing': this part of attack disc was used to get the gyroangle.it is not included for two reasons.first ,the attack disc was too 'heavy' with all these divices and was confusing me,
and second (and more important) is that using the discs to find the gyro is not very simple procedure.it is better to do this on your navmap once you have determine the target's course

ps:the tools needs a lot of studing Nissum,don't expect to 'get' them with one glance.the capabilities of these tools are ...'infinite'. ''studing'' is .....your friend here

Well...I seem to be having these minor problems concerning MaGui (i.e. MEP) but this time a little more specific. The AOB wheel in the TDC panel seems to be off by 20°. The "A" disc (outer wheel) which turns with the course of the boat is off by 20°. If my true heading is actually 180° the wheel will say 160° or 55° it will read 35°. The above quotations explains about the wheel(s) and their many functions, and I see that their A wheel is pointing to where it should, or at least i think so. I can still use the tool for AOB and other course and bearing calculations, however, this 20° discrepancy is somewhat irk'ish. Granted, I don't really need it, just wondering what the heck???? Perhaps an edit to the files??

hello Comet,

i don't know what is going on with your installations but the issue you describe at your previous message is not happening
take a pic with the problem, register to http://photobucket.com/ and upload your image there .once you done so...the photobucket will give you a link for the image (under the pic,the one at the very bottom ).copy this link and paste it here

bye

Dangdabbit!! I already have a photobucket account. I never thought to do that. Bummer. Will upload and send it here very, very soon.

If you look at the upper and lower left corners, you'll see that the compasses are true. Now look at the top of the AoB wheel...20° difference. The compass shows about 102° whereas the AoB wheel shows 82°.

There is no error!

I suggest you look at the little white triangle (on the moving brown background wheel, a bit below right side) and see it is neatly against the 101 degree. Confirmed by the compas readout on the lower left. And by the normal compass dial.

The "N" at the top of the yellowish disk DOES NOT indicate your course.

Oh good grief you're right! I didn't see that in Makmans' explanation in the other MaGui thread. I totally forgot about the white arrow. My bad. Please disregard this thread. My fault. Now...back to the show.
