Hi John,
the flight path vector (again I can't recall the specific term for this aeroplane) was showing a steep descent ..
I don't think the flight path vector (bird) was ever displayed. The HDG/VS TK/FPA button on the FCU needs to be pushed in order to bring up the display. I can't find any reference saying they did.
Normally a crew would ask for "FDs off, bird on" - but this crew kept their FD switches on, and seem to have been trying to follow erroneous FD commands (e.g. VS +1400/min during the descent Page 96 Final report).
