The method really works great for surface attacks ... especially after you've blown your O'Kane-type setup. Just put the TDC in manual mode, input target speed (you still must figure that one out yourself), set an AOB of 90 degrees, WAG an intercept course, lock your target, wait until it's in profile, press the button for auto, and fire a spread.

As long as you're in manual mode, the target's AOB will remain at 90 degrees. As long as you're locked (and in manual mode), the scope/UZO will maintain azimuth ... but the TDC bearing won't move. Switching to auto-TDC just before firing sets the TDC bearing to your target's current azimuth ... while leaving the AOB at 90 degrees.

In other words, you now have a proper firing solution. If your target's speed is correct, you can even unlock and delay firing so as to pick your sweet spots.

For Fleet boats, it's a bit more complicated. The TDC works differently.

Unfortunately in SH4 you either have manual or auto, you cannot change once you start a patrol.
