dnme, I have to disagree with you.
You continue pointing out how "weak" ED manuals are. No beginning middle or end. I completely disagree.
Flight Sim manuals are not supposed to be in certain order. Due to the immense amount of information required to understand and operate the systems there will never be a way to "properly" write a manual.
First, you need to know what you WANT to do. When I first started with DCS-A10 the manual looked daunting. I didn't think "Ow, ill read the whole thing". I thought to myself "Okay, so I don't know how to start up, let's read up the procedures"
After that, I thought "Ok, I want to learn how to use the TAD". Went to the corresponding page in the manual (using the table of content of course) and it was wonderfully explained there. Every time I wanted to learn something which I didn't know how to do, I opened the manual, found the "section" I needed to read. Read it, practiced it in-game, made adjustments and tried again.
I think the manual, while having some errors, Is concise and clear. When I reached the weapons deployment step, Deploying the Mavericks was one of the better explained portion. With step by step instructions.
You will always be flooded with acronyms and jargon you will not understand at first. When you run across it in the manual, Search it, it will most likely be explained. I too, did not know what SPI, SOI, Hooks, Ownship and all that kind of stuff. But a quick search in the manual backed up by posts in these very forums completed the entire picture for me.
Be patient, you will not learn EVERYTHING that quick. Reading and understanding is one thing. Implementing what you have learned is another, and doing it under "combat" situations is another. These things take time but most importantly they require your dedication. Don't expect everything will be handed to you on a silver plate.
My 2 cents, Good luck with your learning. I'm sure in no time everything will make much more sense.
