There's a user-made Google Play app called DCS World Encyclopedia. I've used it on my phone since I don't have a second screen and prefer to use my laptop for checklists. Has a search with suggestions that speeds up lookups, but you can also browse based on category (ship, ground, weapon, etc) and type (air defence, armor, cruiser, submarine, etc). Would suggest using that as a sort of quick study bible.
Maybe like a guide in pdf format kind of thing. or something like thos app:

I used to play a lot of dcs and this app was helpful. Something like this for KSP would be amazing! A quick encyclopedia. Idk how to write code but if i knew i would make an app for ios.
Maybe I'll learn down the road if i don't find anything.
► DCS Encyclopedia is pretty neat as a quick reference.
Aerodromes diagrams / frequencies easily displayed.
