That method works, keep in mind that your course can't change either. So you either don't change course or set up the shot based on a future position. I'll usually set up the shot while I'm taking readings on his speed and course. |
Thanks, DrMilton & mheil for your nice comments.
You can change your course slightly for a better attack position without determining a new AOB. As your boat turns, the new bearing is reflected in the TDC's computation; thus turning the boat (changing course) acts the same way to the TDC as turning the periscope/uzo.
For instance, you've established the AOB to course intercept and have loaded it into the TDC along with target speed. You know that you want to have a torpedo run of approximately 8oo meters, so you've manually put that into the TDC. But as the target approaches some 2000 meters away, you're on too steep an angle for a 90 degree hit. So, slowly turn (5 degree rudder) toward a more perpendicular angle to target's course as it approaches. There is no need to change any information in the TDC. With this attack position, you're so close that any minor change in true AOB would be minimal. Torpedo Los! when the distance and angle are optimum.
