All this docs and manuals – is not real FCOM, e t.c. This is docs for computer simulator, a “game”, if you like. For this reason this docs should not be used for preparation of a320 pilots in real aviation! There is too many simplifications in the simulator and to understand how to operate the systems in the a320neo by JARDesign, you can use “How To” videos.
