Bearing change tables for speed

[derstosstrupp]

Hi All,

I’ve made tables for the method I use in my Comprehensive tutorial in my sig (computing target speed based on his bearing change over one minute). I’ve put a link to it in my sig. I used a self made whiz wheel in my tutorial but wanted to make the tables for ease of use So people could print them off and keep them at their desk. Instructions are in the document.

Tutorial is written using SH3 but of course the methods work for Wolfpack as well.

Edit: Please also find a link below to an excel file I created that does the grunt work for you, just plug and chug! This is set to read-only to keep the integrity of the file, so please download for yourself (File - Download As - Excel)!

Wow, this is helpful. Tables are a great asset, I'm going to add these to my command book.

Had these up last night to use against our convoy! Works great!

Wanted to have a look-see, but it says i need permission. You sure you have it set to public?

OK try now?

I have made a change to this file, adding the historical fixed wire speed method table from the 1938 Kriegsmarine Torpedo shooting regulations, as well as adding a little background about historical methods of finding speed. Link has been updated in my signature.

Could someone please confirm they can open it?

I can.

BTW it reminds me of another bearing change method which is Ekelund Ranging. But looks like the Auswanderungsverfahren is not a bearing only method.

Could I request that you increase the font size of the explanation text - by the time you've zoomed in enough to read it, you can't scroll down and see all the tables.

That’s correct, need one range and one AOB estimate. Albeit these can be relatively rough estimates and you can still end up with a workable speed, especially if you shoot close.

Not a problem, will work on it and put up after work.

Thank you

May I also point out the size / scale of the first table could be bigger to match the size / scale of the second table - it would minimise wasted space when printed out (smaller borders too?) and make reading everything clearer when on a computer screen, where everything can be the same size.

Thanks for everything you've been doing to contribute to the game and community btw.

Edited OP to include a link to an Excel file I created that does the number crunching for you!

It is read-only so don't rely on it too much in a pinch (kidding, just download a copy for yourself - File, Download As, Excel).

Made some edits - the size of Table 1 is a bit bigger, but will be smaller due to the fact that I want to keep these printable to 8x11 letter size paper for reference. Edited instructions as well. Check out the Excel file I just added too - that's also an option.

That's brilliant; thank you!

Derstosstrup, do you have templates for those slideruler disk for Auswanderungsverfahren and Ausdamphverfahren? I feel a creative urge coming up.

And once I figure them out, I might even redraw them in CAD software.
