Whatever your project is, why not adress Airbus directly?
I mean, Airbus has a general FCOM set that is shipped to every customer. Most of us only have access to customised FCOM of our employers which is a priced intelectual know-how we do not want to see circling in public domain.
Apart from the generic FCOM, Airbus Training Centre in Toulouse hands out "training only" manuals to every pilot for training with them.
What better way to represent themselves, than to support an aspiring student? Perhaps you may find the contacts very useful some time later.
First manuals I got my hand on were from now defunct Air Luxor, who had published all FCOM at "AirLuxor Virtual" section of their web. The site is down as the company ceased to operate, but certainly someone in Portugeese AV sim community will have them.
If no luck, keep us in the loop.
