Random question on this topic:

Why do the tables' solutions differ from what the TDC's on the exact same shot?

Ex. 30kt Chart for a 7kt target shows 13.1 degrees to shoot. But if I set up the same shot in the TDC it gives me 15 degrees to shoot for a 0 degree gyro.

Just been curious.

Thanks for the awesome mod!!!!
hello Tupolev,
thank you for your kind words
about your question: i believe that you haven't set up correctly the TDC thats why you see this difference.
look at the following pic,it shows the correct TDC setup for your example ( pay attention to all marked points):


now, turn your scope till gyro dial shows 0 degrees and take note of the shooting bearing:



just a comment : you must 'expect' a slight difference at shooting bearing between tables and TDC becuase tables are NOT taking into account the 'torpedo tube parallax correction' (but TDC does) and as i said here : http://www.subsim.com/radioroom/show...&postcount=432 prefer to make shots up to 2km when using the tables becuase range is always a factor ( but less when shoting at 0gyro)
