First, a little history!
I have a real NL-10, Russian aviation slide rule (linear), which I used many years when playing flight simulators.
For me it is fun to do calculations with slide rule. I use NL-10 also for SH3.
A few months ago, accidentally noticed in the net, these Dreieckrechner slide rules.
Luftwaffe navigation!
Then I came across a site, where was DR3 flash version and a printable version.
I downloaded the files for the print version, with the idea, that they may be useful.
And I forgot about them.
But this weekend, when dig in my computer, I saw these files again.
I decided to put this in the game (SH3). On Monday I had a working version.
Then, I searched again for this site, but could not find it.
The site was not in English language, but I do not remember what language was.
But then, I remembered that it was associated with IL-2 Sturmovik.
And with that in hand, google found a site, in English, of the author -
VO101_Tom.
I asked and he kindly provided me permission.
If we look at the available variants for SH3, and this DR3:

They do not differ significantly, used the same concept.
Here is needed to thanks to,Onelifecrisis, Joegrundman, Hitman, Makman94 and all other GUI moders!
From their mods, I study how SH3 menu things works.
From the original graphics, I delete the scales for temperature and height, which are for IAS - TAS.
Then I had an idea, to do a second black ring, which stands in place of the degree scale.
Just to have the opportunity to easily and quickly implement simple calculations, for multiplication and division.
The mod look and work like this:

First, I will prepare DIY version. Then, will think about other versions.
