While the TDC basically computes a lead angle intercept, its limited to solving with only 3 speeds: 30kts, 40kts, 44kts. Even if you were able to input a correct AOB (which itself would take solving an equation or navmap plotting) and target speed, the lead angle provided wouldn't be accurate as the U-boat isn't making 30kts+.
There are a few GUI mods out there that provide a simulated attack-disk (can't remember the real name of it) and directions on how to use it to solve for the intercept angle and course. However, I've found it more expedient to just do the drawing on the navmap. YMMV.
