What did Airbus do in between?
Posted before but to refresh the memory:
(not all related to AF447)
All Thales probes have been replaced per AD 2009-0195
Besides the probe replacement program, several hardware and software changes have been introduced:- BUSS (SW always available) - already available before AF447!
- FMGEC: AP/FD not available at UAS condition. AD 2011-0199R1
- FCPC: F/CTL ALT LAW (PROT LOST) ECAM MSG accompanied with reason.
- FCDC: More rigid 'USE MAN PITCH TRIM' PFD message when autotrim not available.
- FWC: **NAV IAS DISCREPANCY MSG When 2/more IAS are detected to be different.
- Added AoA data filtering to improve SW detection in turbulent conditions.
- AoA: Conical shaped ground base to prevent water ingression.
** Don't know if F-GZCP was equipped with this mod but the mod was available at that time. (BEA doesn't mention the presence of this message, suspect it was NOT available in F-GZCP)
