What else is the "STALL, STALL, STALL!" aural warning? It occurs
before the actual stall (as well as supposedly during it, different issue, that).
Certainly not relevant (and not justifiable) in normal conditions.
My suggestion and argument, entirely.
AFAIK we are still relying on "sub heated" Pitot 's.
Not necessarily "sub-heated".... but still "sub-qualified".
AFAIK, the Thales AA and AB probes, just like the Goodrich (?) probes, all met the certification requirements. The real problem is that none of the certification requirements fully account for the conditions encountered by AF447, and during other UAS events.
I'm looking at this a bit from the engineering point of view.... "I can give you a better pitot, just tell me how to test it to prove it's 'better' and meets your requirements".
And so far,
AFAIK, those environmental conditions, and certification tests (dating from way back) have still not been updated.
The UAS procedures are nothing more than a stopgap and a BandAid.
UAS should no more be possible.....
