but on the whole you are talking about how to use the tdc, not the whiz wheels.

the tdc in the u-boat simulator is basically 4 dials: speed, range, aob, bearing.

there is a switch/button that puts the tdc on or off. find it.

you have to switch this so that when you try and click on the pointer in eg the range, it moves.

set the range to your desired range

do the same with aob

do the same with speed.

- you can forget about bearing. bearing will be taken auto from your scope, but good idea to have the scope pointing at the target at the time

flick the switch again. the tdc is now on auto which means that if you move the scope, it will auto update the aob.

or to put it another way, if you have the bearing at 70 and an aob of port 20 and you plug this in and turn on the tdc, when your scope tracks the target as it advances, the new aob will be constantly updated, so when your scope is now at 000, the aob dial will show port 90. try it and see on an imaginary target.

so that's all done for you, once you have it set correctly you can just wait until the target is in the firing position, no need to mess any more with the tdc, just track with scope and fire.

spreads are also very easy since you just point the scope at the bit of target you want to hit.

The issue is simply how to do the manual targeting tasks in a UBoat. I can do them in an American Sub in SH4 PTO and Trenchboats. I will give it another shot and post if I continue to be stuck.
