Shouldnt Airbus be making this officially available any way?
Yes, to the operator of the aircraft. I don't know what you're using it for, but if it's course pre-study, be aware that the FCOMs are operator and airframe specific. My company's manuals are very different to other's as we have a lot of company input for our SOPs and for the various aircraft options, for example the ACARS performance system we use.
