But using the manual tdc you don't have to do the calculations?
I think that the SHIII notepad is an excellent compromise and gives an excellent representation of the Captains role in making a submerged attack. As he gives the information and the solution done from this. The only flaw is the speed calc method. Which can be worked around by clicking the 'full' manual TDC at the bottom of the F6 screen.
I have always thought that no-one has ever got the auto tdc right. It is a difficult problem, in that it must be accurate enough to be real, but inaccurate enough to also be real. SHIII has not achieved this, as it is very accurate and very fast to be so.
The problem with slowing down the WO is that you cannot preplane a shot bearing, thus his calculation is only good for that instance.
