Boac, yes, well in that case, only these two:
The PFD flag at 210Z was an "airspeed limit" warning (error code 2283)
The PFD flag at 211Z was a "flight path vector" warning (error code 3412)
fell into the definite bin.
These results were passed along via an exchange of emails so I will try a prearranged phone conversation to see what else can be made more solid in the list.
On the "prototype airliner", the A300, Flight Path Vector, is a PFD presentation that can be selected on the glaresheild to predict on the Attitude Display where the mass of the airplane is going to wind up. You "Fly the Bird" target and it helps you manage energy. I know it would likely be a cascading failure from either the AIDRU, airspeed data loss, or the IRU portion itself. Is the A330 the same?
(A330/340 drivers are amazingly silent today...)
