A320 AOA
Hello all,
did Airbus do anything (modification) regarding two AOA stuck at wrong angle with the third correct AOA voted out? I do not mean the OEB but I mean modifying the coding of F/CTL computers....
Also, the AOA discrepancy ECAM caution in the FCOM looks new for me. Does it have any connection with issue above?
Thanks

Yes, the computers can now detect two AoA vanes frozen at the same, but incorrect, value. It's a combination of a switch to Thales vanes and enhancements to the flight control software
The idea is that a consistency check is carried out between the load factor and the angle of attack reported for each AoA sensor. Implausible results lead to a rejection of either one probe (which is a non-event) or rejection of two, which leads to alternate law.
I believe it was implemented with ELAC software standard L97.
