TDC bearing dial - ignore it?

I don't think there's ever any need to use the bearing dial. It's always better to use the scope for this sort of thing.

But if you are already on your firing course, then you are right in thinking that if you have the scope locked on and plug in the correct AOB first time, then there is no need for any further adjustments

First you want to determine the AOB at the intercept point of your course with the target's course. There are two ways to do this: mathematically by computing the difference between your know course and target's estimatted course or by using the angle tool on the nav map.

Once you have the exact angle at the course intercept point, go to the scope/uzo screen. Set/lock the scope/uzo to zero degrees. Zero out all data on the notepad. Click on angle on the bow on the notepad. Manually set your previously computed angle on the angle on the bow notepad page making sure you select the correct direction of target across your bow, either port or starboard. Click the checkmark on this page. Click the checkmark on the main notepad page. You have just set the correct AOB at intercept point into the attack computer. You can now rotate the scope/uzo to the target and as long as the target does not change course, you automatically have the correct AOB as the target travels along its course.

Note: always zero out the data on the notepad once you have set the AOB because if you later use the notepad to set speed or distance you could have a resulting incorrect AOB if it had not been zero'd out. This is a good rule to folow once you have set any data in the notepad.

Hope this is helpful.
