RetiredF4:
How do you translate "10° climb" in Nz demand? After all, once stalled, the g were around 1...
The law is not a "pure" g-demand one, IIRC. "Corrected for the path", or something like that. Cannot do the maths, but would be interested to know more.
deefer dog:
1/ No, unless switching off many computers (=not a feature/approved procedure). Against the Airbus philosophy.
2/ There is no such computer logic. Perhaps you've read Otelli litterally? Well, he's wrong here, there is no logic AoA>41°=Cancel SW.
The logic is :
- if current AoA > value calculated for SW then
-- SW is triggered
- if speed < 60kts then
-- AoA measurement is deemed not valid, whatever value the probe sends is "cancelled" (& AoA is flaged "NCD", no computed data); reason for doing that is [my guess] that will less than 60kt of relative wind, there is not enough airflow to get a correct/precise AoA measure from the AoA probes
The "problem" is that if AoA is "NCD", then AoA value (or "non-value") does not validate the condition for the stall warning: "NCD" is not superior to X degrees AoA.
