tdc question

[Laffertytig]

if i input data (AOB + speed) into the tdc and set it to auto and then change course and speed, will this mess up the solution?

im find tryin to figure out AOB at night is impossible so my idea is to set up the tdc in daytime then when night falls, turn towards the convoy and attack. will this method work?

Yes, it will mess up the solution.

But what you can do is if you know target course, and therefore your own future intercept course, point your scope/uzo directly forwards, and go to the F6 screen and set the AOB to 90 port or starboard, whichever would be correct for when you hope the target passes in front of you later that night, and then that's it

then whatever course you are on, it doesn't matter, so long as you are on a normal firing course (perpendicular track) at the moment of firing.

If you wait that long for the attack it is easier to simply plot it's positions every once and a while. And so get it's course pretty accurate to which you can position yourselve at 90 degrees. Then like joegrundman says, point scope at 0 and set AOB to 90 left or right. This also solves the problem if the target makes a course change in the mean time. Because of plotting you notice the change well in advance.

No. Only if the target changes course and speed will your solution be messed up.

That's actually what the germans preferred to do. They did the end around during daylight keeping the top of the convoys masts in sight above the horizon and carefuly observing enemy course and speed by comparison to their own one. Then they waited the convoy in the chosen spot and attacked by night, setting mainly the values they had collected by day if visibility wasn't good enough for double checking.

I think you're mistaken on this one mate. Changing your own course will defo mess up the firing solution!

Bah! You kids and your "computers"... and yer.....music.

Real Kaleuns aim the WHOLE boat and make a good guess. Iron sights FTW!

Really?

IIRC when you change course you are effectively changing only one side of the triangle, i.e. the bearing to target, therefore the TDC can autoupdate it. If the target changes course it is a different matter, because the AOB changes and that one is updated through your bearing to target. And because the bearing doesn't change, your solution gets screwed.

Will make some tests and confirm :hmm:
