That is not correct, the 3°+ that is.

Interim Report #3 page 86 states :

Standard altitude (ft) 34.992
Computed airspeed (kt) / Mach 275 / 0.80
Pitch attitude (°) 2.8
Total weight (tonnes) / Centre of gravity (%MAC) 218 / 27.5

We can see that at the same altitude and speed but 13 tonnes heavier a pitch of 2.8° was required. At the actual weight of 205 tonnes the pitch would therefor have been less. Somewhere between 2 and 2.5°, probably closer to the 2.5 than 2.


...and power that was set correctly for an airmass that was markedly different in two seconds from what was indicated...


Interim Report #3 page 88 states:

2 h 09 min 58 Speed handling changes from managed to selected. The selected Mach is 0.8.
2 h 10 Pitch attitude decreases from 1.8° to 0° in 3 seconds. In 8 seconds, the N1 commanded and the N1 change from 100 % to 84 %.


A reduction in speed from .82 to .80 was selected and the ATS responded accordingly.

AOA did not reach 9° until approx. 02:10:55, some 50 seconds after AP disconnect and with the aircraft at 37500 ft. It did not exceed 6° untill 02:10:50, some 45 seconds after AP disconnect. See pages 42 and 106 of Interim Report #3.

I am also still looking for references to where those quotes you attributed to BEA comes from. I don't think a "keep looking" will do.
