Thanks A33Zab.

Can anyone comment on:
- the relative precision of the AoA "from an ADR" and "from an IR"?
- the relative failure rate (whatever reason) of an ADR vs an IR?

I'm trying to understand why the ADR AoA was used on planes, if IR AoA is/may be available too, and the latter not being subject to AoA probes icing (Perpignan), nor speed problems "pollution" (AF447).
