NOT an easy failure, requires some Airbus thinking. Cheers.
Excellent hint, Bylaw, that's what it was, DC ESS BUS FAULT.
Btw, you recognize it when gray background of speed tapes on PFD disappear - if you still have a PFD
I agree it's difficult to recognize this failure and needs quite some switching (especially for radio). Airbus syllabus doesn't cover that failure, you don't speak about it at all during your whole course. We played it through in Swiss Training where you do a bit more than just basics.
