What happens if two are in error? I am of the understanding that the manufacturer (Northrop-Grumman) admitted that 5 defective ADIRU's came off the production line in sequence, 3 ended up in QF aircraft, with2 defective units ending up in the aircraft involved in the incident (QPA).
If this comment relates to the trouble with QF72 then it is surprising that the author, Matt O'Sullivan, did not mention it, but quoted Captain Kevin Sullivan as saying about the way the unit was taking good information in and pumping out extreme data , " They don't why it did that. And there is no result."
Incidentally, 'Centaurus' should be along shortly to give his learned views on the excessive reliance on automatics and computer systems.
