with respect pj. my main aim in hammering home the acars point is to stop this nonsense about a vs departing the aircraft first.
One can determine that the vs was fixed in place due to a complete lack of real time messages relating to a whole range of other systems that would shout fault immediately.
The problem with reading the manual without the specific aircraft experience is that you can read more into a technical statement than is actually there.
I can assure you that a departing vs would excite the fids to such an extent it would shout fault in real time
As to the rest of the sequence of events I may even agree with you
