Hi Clandestino,
And what bearing on AF447 does it have?
The most important warning on that flight deck was "Stall Stall" - which appears to have been ignored / not acknowledged / not heard. (Similar to the You Tube "What's that Beeping?")
If their human auditory channel was filled to capacity with previous flight deck audio noises, (Cavalry Charge, ECAM Dings, ALT Alert etc), and the crew are attempting to verbally communicate whilst they trouble shoot - what is the point of having the only stall warning alert simply another verbal "Stall Stall"?
Even my iPhone has both audio ring plus Vibrator to get my attention.
Do most other aircraft have a stick shaker as a stall warning? If Apple can fit one into my phone, why was it not possible to fit something similar into the side sticks?
Before AF447 event, there was NO Stall Warning QRH procedure. The previous procedure was buried in FCOM.
The new QRH procedure emphasises reducing angle of attack, and does NOT recommend the use of TOGA power. (as the old FCOM procedure did)
