Looks like a DC ESS BUS FAULT.
Have to do some Ecam/Air Data switching to get captns PFD and the status page back.
Cab press 2 available, no need for em. gear ext. as LGCIU 2 is still there. Both gen`s are working, no RAT.
Also you loose a lot of non essentials.
Anyway, it`s not an easy one as for instance RMP 3 (radio) is the only one working, together with CAptn`s PTT!
Fire pushbuttons have to be used to shut engines down as FCMC 1 and 2 (part) are not working.
NOT an easy failure, requires some Airbus thinking. Cheers.
