Thanks, my FCOM/AOM shows ADIRU input into the ISIS, but I'll take your word that it derives it's own attitude and airdata information.
Be that as it may, my point is still unchanged. Everything on the panel is computer generated. The only thing I can count on in the Airbus is the horizon out the windscreen.
If I was scared of the technology, I'd never go to work or I would change employers and go back to flying a DC9. However, I want to understand the technology.
On a related subject, I have been in a 319 that failed to respond to SS input asking for nose down. I was maneuvering, avoiding one buildup and flew into another which was a substantial updraft. I had already pitched for green dot trying to climb above the first buildup and when I flew into the second updraft the aircraft failed to respond to my nose down, fwd, SS input for a couple of seconds. I assumed at the time that the updraft caused a "g" loading that fooled the ELAC. The buildup was small and we flew out of it in a few short seconds. PM me if you have any input.
