Because without much airflow at really low IAS gravity affects the position of the AoA vane just as it does on the ground? The designers had to choose a speed - they chose 60kts.
Not too sure about that one
Tyro ...
Could be an indicated airspeed of 60kts or anything below, AoA probes won't be affected by gravity with an obvious negative vertical speed of 100kts or above.
henra, I don't think there is anything as Alpha Floor protection in case of A/THR failure.
No one would trim up beyond a STALL WRN, how is it possible the Airbus still
auto trim after such warning ... !?
Things don't add up here.
Svarin, your comment regarding the wiring (WRG) ACARS message is interesting. You will need to tell us more.
