assumed trajectory for recovery
Would somebody explain, on what facts the following happens in the first 12 seconds of the above graph:
Pitch is reduced from +15° to -10° = 25° change
FPA increases from -22 to -34 = 12° change
AOA decreases from +35 to +22 = 13° change
Speed in this timeframe is not specified, but is esentially important for generating lift. Drag in this AOA regime has an influence as well, where can it be found in the graph?
On what ground would the AOA change (13°) be grater than the FPA change (12°) by changing pitch (25°)?
Wasn´t the initial AOA according BEA higher than 40°?
Out of my own expierience with such a high initial AOA and such low speed the pitchdown initially increases the FPA by the same amount, the pitch is decreased,, giving only a minimal change in AOA and an increase in FPA and descent rate.
The expierience in the A330 sim from PJ2 and another Airbus pilot make me believe, that this magic graphs miss some vital points. Also all accepted procedures for combat jets as well as the new updated stall recovery procedures speak of the need to place the stick forward until the stall warning stops, which would not be the case until 45 seconds into the recovery like shown in the graphs.
