thanks guys!

Platapus, I know how AOB works, but thanks anyway!

Thanks for that answer joegrundman!

hmmm... that got me thinking..:hmm: Would it have been possible to design the TDC in a way that allowed the "AOB system" to be linked to the compass heading/course.

I.e a change in compass bearing would cancel out a change in relative bearing to the U-Boat in order to maintain the correct target AOB?
Basically the TDC AOB would subtract any change in true course from the AOB and apply it to the AOB wheel?

For example if my current compass heading is 0° north, the target bearing is 90° (which would obviously also make its true bearing 90° (east)) if I then turn 90° to the right towards it so the bearing is 0° the TDC would just have to subtract 90° from 180° which would mean it maintains the correct AOB.

But then the TDC would have to be linked to the rudder system so "it knows" if the boat is turning to port or starboard right?

Sorry its difficult to explain for me... I hope its makes sense
