I was provided a large amount of material and after checking, none of this is classified, FOUO, or marked for NFD. As such, this is basically 'good to know' information. I have pages and pages of this crap. I'll also point out that some of this information is deprecated, and it mostly pertains to the A-10A, as evidenced by some references to obsolete HOTAS commands. I'll see if I can get my hands on A-10C information, but much of this remains valid between both models. I also don't know just how accurate the sim is in regards to some of this.
This is essentially what the Air Force considers 'training' for avionics techs, even though quite obviously a lot of it doesn't apply to our job. The theory, however, is that by being able to understand exactly how the entire system works, it'll make it easier to troubleshoot. These are ripped from our CDCs. Again, no classification level of any kind is present on this information. Provided for you, the A-10 enthusiast. Hopefully someone can find some good info here.
ED: Consider this another official source for A-10 information if you discover a way to enhance a feature. For example, it's suggested that EAC can fall offline in excessive PAC conditions. I also have far, far more information on the F-15C and E, so when you make the next module (:)), I can provide a lot of unclassified information if need be. DCS A-10 Gun Information - Expanded.pdf
