Step by Step for AOB

rdhiggins · 08-04-07, 02:33 AM

Can someone please give me in simple terms the best approach in determining the AOB. I don't need any trig or math professors instructing me to perform a rocket equation but something simple and more accurate then what I have been doing.

Before anybody suggests that I utilize the search forum option.... trust me I have!

I have looked at the wheels, other peoples way of suggesting it... and lately I feel defeated since sometimes I feel like I am making progress and other times I feel like I took 2 steps back.

I understand what the AOB means such as if I was on the enemy ship where the placement of my sub but I just don't understand how to go about and determine the steps to determine the AOB.

99.9% of the time my shots are either way before or way after.

and by the way is the yellow tick mark in the six o'clock position of the upper dial in the TDC the target course? Or is it the white arrow?

Thank you, and appreciate any help!

If you don't want to calculate, make a guess based on visual appearance. To help with this, look at the recognition manual. There are three buttons in the upper right of the recognition manual, one of them will swith from a side view to front and 45° views. Compare that with what you see.

Also, if you use the automatic speed estimate in patch 1.3, look at the message window, it also includes a course estimate. Be careful, as it is quite sensitive to the accuracy of your stadimeter measurement.

1° there are several methods to calculate aob, use the search function
2° Always try to shoot within 1500 yards.
3° AoB is not as important as speed calculation, a couple of knots makes a world of difference

1) determine enemy course, plot it on map

2) position your sub well ahead of contact, perpendicular to enemy course: your projected course should cross enemy plotted course at a right angle; use the protractor to verify if necessary.

At this point I usually come to a complete stop, 1000 yards from the target.

3) set view in periscope or TBT to 0 (zero) degrees

4A) target on your starboard/right side - point view to target and note bearing: for example 35 degrees, subtract that value (35) from 90 to get 55 in this case. That's your AOB. PORT 55 or 55 degress on the left of enemy's projected course.

4B) target on your port/left side - point view to target and note bearing: for example 300 degrees; subtract 300 from 360 to get 60 and then subtract that value (60) from 90 to get 30 in this case. That's your AOB. STARBOARD 30 or 30 degrees on the right of enemy's projected course.

Yes, it's that simple. Took me a while to learn back in the SH3 days...

Watch this movie and there you can see how you simply can determine the angle on bow.

When enemies are displayed on the map you simply can draw a line on the cours of the ship, on the ship and then to your sub en see what the angle is.

Thank you for all those that have responded...

Just a question does anyone know how or why enemy ships do not appear on the regular map? (they do appear on the attack map)

when I began this patrol they DID appear but then something happened and now they do not appear. I don't know if this is related but I am currently attempting to attack a convoy in storming weather, the enemy I identified is 2 Coastal Freighters and a destroyer. The Coastal Freighers are 1600 away and the destroy is about 800.

Rocknut,
Thanks mate, i had just a quicklearn how you did it. And i had in the
torpedo tutorial a 100% hit. Will try this also in sh3. I always used the map
to get the aob. Last missions i did it on sight.

I have just begun to play shiv and i didn`t understand how to use the tools.
