Thanks!
So the only thing the TDC has to calculate is the angle at which to fire your torpedo's, or alternatively, the 'gyro angle' in order to shoot straight at 90 degrees and still hit your target right?
Sorry for being really 'semantic'...I have this stupid thing that if I don't understand a thing 100% I have the feeling I understand it 0%, even though I might understand it 95% (if that makes sense...drove my teachers MAD years ago!

)
