Well done to the MAA for highlighting that this is yet another "Lessons Not Learned" case.
But am I the only one appalled at the bald admission that UORs are introduced without functional safety being ensured? The report implies the associated risks are taken into account and assessed, but this was not the case when the policy was "don't bother".
And nowhere does it say that it was stated policy since about 1996 NOT to modify simulators or address training which, by definition, means one cannot declare airworthiness. That omission is crucial. (Fox3, quite right).
