Traces on page 107 and 108 do NOT show any bird selection.
I had the same conclusion:
FDR trace (page 107 BEA Interim #3) shows HDG/VS selected all the time,
or is this a wrong conclusion?
however:
BEA Interim #3 - 1.16.6.3 Page 47.
The presence of the “FLAG FPV ON PFD CAPT (F/O)” message indicates that TRK-FPA
(Flight Mode Annunciator) mode was selected by the crew during minute 2 h 11, but that the
FPV was unavailable (see interim report 2 for details on the conditions of availability). Based
on a study of the other relevant parameters it may be concluded that the FPV was selected
between 2 h 11 min 48 and 2 h 11 min 54.
BEA Interim #2 - 1.16.2.4.1Page 35/36.
FLAG ON CAPT PFD FPV and FLAG ON F/O PFD FPV (2 h 11)
Symptoms:
Disappearance of the FPV (bird) on the PFDs, Captain and First Officer sides,
and display of the corresponding flag.
Meaning:
This message indicates that the flight path vector (FPV) function is selected but
unavailable. In order to lose completely this function, which is elaborated by
the three IRs, in a way that is compatible with the CFR, one of the following
three conditions must be met for each ADR:
barometric vertical speed higher, as an absolute value, than 20,000 ft/min,
true air speed higher than 599 kt,
measured calibrated airspeed lower than 60 kt.
Once the operating conditions are satisfied again, the FPVs reappear on the
PFD (if TRK/FPA mode is still selected).
