Short version -I was setting the Aob in the exact opposite direction. You may need to think about this. Try to visualize it. This example is related to firing when the target's Aob is 90 degrees, as in an O'Kane attack or fast 90.

"The left side of the Aob dial on your U-Boat says, "Bug Links." Translated this means bow of the ship left. When a target is approaching the bow of you your ship from starboard (i.e. it is moving from right to left) [as in my example above], the Aob viewed from the target's bow is to its left (port). This means that the Aob dial on the UBoat, as viewed from the bow of the target, should be set to 90 degrees Bug Links (bow left.)

The right side of the Aob dial says, "Bug Recht." Translated this means bow of the ship right. When a target is approaching the bow of you your ship from the port (i.e. it is moving from left to right), the Aob viewed from the target's bow is to its right (starboard.) This means that the Aob dial on the UBoat, as viewed from the bow of the target, should be set to 90 degrees Bug Recht (bow right.)

Bottom line, once you have the target's Aob, input it in the TDC with scope locked on the target. With the TDC activated the Aob dial will move in relation to movements of the scope. For an O'Kane shot, when the Aob is either 10 degrees or 350 degrees, depending on the target's heading, fire the torpedoes.

You are correct. Once you change your course, you need to update the AOB on your TDC on the German version(The fleet boat TDC will keep track of it). Since now the target is at a different relative bearing and the AOB is tied to your scope, the AOB will change as well when you lock onto the target.

Let's think this through. Hypo: Assume the TDC is activated and accurately locked on the target. If the target changes course or speed, then the correction can be made by deactivating the TDC, entering the new speed or course, and reactivating the TDC. You might as well correct the range too, if you have time.

However, if only your U-Boat changes course, but the target's speed and course have not changed, logic tells me that the TDC will continue to track it if your periscope is locked on the target or the target is squarely in the periscope's view. The Aob should adjust automatically while the periscope follows it despite the fact that your U-Boat has changed or is in the process of changing course. So, at this time, with the qualifcatrions noted re the target changing course or speed, I disagree with sharkbit. Take a look at the KIUB tutorial by Karamaroznew as he probably mentions it. sharbit's post may (note, I use the word "may" intentionally) be inaccurate, because if the U-Boat turns (i.e. alters course) and has the target in its sites, the TDC is correcting (updating) the targets Aob while the U-Boat changes position. At this point the only variable of the attack equation that should be different is Range, and I do not normally adjust the Range setting as I assume the TDC is tracking it.

Interesting question. Let's see what other responders post. Meanwhile, I would test it out if I could only find a target of the Norther Slope (Norway.) If I am correct, I am ready to teach at the War College. If not, sharkbit is.
