[vilas - not quite sure why you posted "Turbulence, ITCZ, airframe icing do not alter flight control laws." - they certainly alter 'flight'.[
Why, then, does AB not offer the option to the crew to decide what is erroneous and what to do in the 2 ADR case rather than decide on its own course of action which might be wrong?
Anyone with other FBW system experience to comment?
