Is the Ny rear accelerometer used in Normal law?
I realize that this can be potentially be a time consuming area to research, but it might be useful to "sweep out" this corner of the Yaw control system for things that could induce a yaw input in Alternate2 law. FCOM search has been non-productive. TIA
