All Thales probes have been replaced per AD.
Besides the probe replacement program, several hardware and software changes have been introduced, IMO they are optional and not mandated.
- BUSS (SW always available) - already available before AF447!
- FMGEC: AP/FD not available after UAS condition. (Last MOD)
- FCPC: F/CTL ALT LAW (PROT LOST) ECAM MSG accompanied with reason. (Last MOD)
- FCDC: More rigid USE MAN PITCH TRIM PFD message when autotrim not available. (Last MOD)
- 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. (Last MOD)
** 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)
The B787 is equipped with ADR voting logic, details are not known by me, but the fault isolation logic determines which ADR supplies PFD.
Above that there seems to be a synthetic AS available when the voted fails
