See post 813 on Lion thread: ...
If you cannot simulate an AOA failing high (and not all AOA failures will trigger MCAS) then you could only trigger MCAS by flying into a part of the envelope where it is designed to activate in which case the result would be that, in terms of stick feel at least, MCAS counters the additional nacelle lift and it flies like an NG would. That isn't really any help...

It may well be that the only way to accurately simulate MCAS is in the engineering sims at Boeing (or arrange a test flight in an actual Max - plenty spare at the moment - and knock a vane off before you go...).
Thank you very much for clarification and the link.
This is indeed another concerning development - and should have been vigorously fought by the Training Device Manufacturers and their customers!

So I would consider this not so much as a cost saving meassure but yet another a**h*** company culture thing trying to gain dominance over TDMs by revoking access to something one considers as Boeings intellecutal property.
