Concours, what you postulating may be true once the stall was completely developed - my point is that it should never have gotten that far.

No, not Bonin. What he did demonstrated a complete lack of understanding of basic aerodynamics.

It is standard design practice to inhibit indications when that indication is considered to be unreliable - and the AOA below 60 knots is not considered to be a reliable indication. That a...

Fair enough - apology accepted. It's just something I've very sensitive to - the accusations than invariably occur whenever the cause points to something other than the aircraft - that...

Concours, you're talking about suppressing the cause of an accident that caused hundreds of deaths, and it doing so putting additional thousands at mortal risk.
I've worked with perhaps a hundred...

Ian, it's not just the flight data recorders - most of the avionics on an aircraft are several generations behind the electronics in your phone. The reasons are simple - it's insanely expensive to...

I doubt the designers ever envisioned a scenario where an aircraft "in-flight" could be traveling less than 60 knots (it's even hard to envision now knowing that it happened).

IIRC, AF447 was GE CF6-80E engines - the CF6-80C2/80E engines are impressively tolerant to inlet distortion. Some other big fan engines would not have reacted so gracefully.


As an aside, we...
