the newer version with better CAS/TAS correction, thank you sensor_validation
of the FPA and AoA for the A340....during the zoom climb

with the given values of Altitude and CAS/TAS for every 5 sec. I calculated FPA (arcsin FPA = delta altitude / distance in 5s) yellow line;
and then with the given Pitch value the AoA (AoA=Pitch-FPA) blue line

the red and black line for Altitude and CAS has no scale....

if the AoA-protection-law was in regiment in the time between the MMO-exeed and 2 s after the first push with the sidestick, then the graphic show that in this time the AoA was not higher than 5 deg

"the AoA protection law seeks to hold the angle of attack constant at alpha prot" wrote the AAIB Bulletin.....

AoA is not the angel for the wing-flow, it is the angel between the direction of the fuselage and the flightpath (FPA) and the calculation did not include the turbulences.....

(I take away the first version)
