I think back when CONF first posted he stated that his sim was a dual ADR fail to trigger UAS. That would leave one ADR in and AOA would trigger abnormal attitude law, which would stop autotrim. Apparently without putting up the PFD message which also ties in with what CONF saw [yep I agree, sounds stupid, think it should be fixed, but not relevant to 447].
I don't think the SIM would replicate the fall in measured airspeed at the pitots at high AOA and fail all ADRs as a result.
