Using protractor for AOB

[Bando]

I saw a lot of questions on Ubi forums to determine AOB manually.
Although a lot of info is already shared on the fora, I have not seen the use of the protractor (or I've missed it)

What I do is determine the targets heading (by radar, visual or radiosignals) and plot the target once closer. You'll get something like this:

Than get the protractor and set the first leg on it's futere course somewhere near you, and move along the reciprocal towards the target, like this:

Than click and move the second leg over your sub, like this:

The angle is shown as XX degrees, which basically is you AOB.
I mostly use an angle which is easy to set, and wait for the target to be on that spot. Keep in mind that the second leg has to stay over your sub, so if you're moving be sure to update the second leg frequently.
In the next image I've set the angle at a easy to insert number (10 or 25 degrees or so) in this case 10 degrees and as you see, the target will get there and I'll switch to periscope and insert the AOB.


I hope this makes sense.
