Important issue to be discussed. Simple devices with so much (Systemic) responsibility, that
failed in AF447? and triggered the sequence of events.
1) System redundancy techniques are good for random (time) element failures.
2) F-GZCP Pitot's failed? They had just a "brief thermal glitch".
3) Pratically SIMULTANEOUSLY.
"Who" failed?
IMO, this is an complete ABSURD!
And ongoing?,
as CJ ask.
