TDC

This matches my understanding of the USN's fire control and procedures.

This begs the question: since the Germans linked the p/s to the TVR, and we had a link from the TBT, why didn't they link the p/s to the TDC?

From BigWalleye:

Was it possible to get the TDC to calculate a deflection angle and include that in the gyro angle setting? The in-game TDC requires that you estimate your own lead angle, just as if you were duck hunting. That's a learned skill.

I don't see what you mean here.

How are you defining deflection and lead angles?

If you input the correct Target bearing, range, Aob (i.e. target course), and speed, it calculates the required gyro angle to hit the target, and this is updated in real-time. What else is do you need?
