Voice of Experience.
Recently flew an A330 at night through a massive and therefore unavoidable stormy area in the Med, painting green, no red/purple, climbing, lost airspeed indications, A/P disconnected, ditto A/THR, into Alternate Law, flying raw data. For about 16 minutes. No CB's, just icing and mod/severe turbulence. AOA discrepancy acc. QRH. Demanding.
Had this happened in a CB area, with wx radar u/s, things would have been even more awkward.
Had the AF crew experienced a reversion in bad weather, it is conceivable that the a/c could have been difficult to control. No difference in this situation between Airbus and B777.
All conjecture. But sadly much amateur guesswork posted here. I cannot comprehend why amateurs would wish to post their "ideas", any more than I would start posting my thoughts on neurosurgery on a dedicated website.
Many fools on this site. Pity the media pay it such attention. Perhaps that is why our PPL/SPL/aviation enthusiast pals feel the need to post. Devalues the discussion.
