About Alter's last BSPN, there is a more simple "credibility test" one can do:
Alter writes that the events (loss of speeds & other associated alarms) "
conduit les pilotes à perdre le contrôle de l'appareil (alors même qu'ils effectuaient scrupuleusement la seule procédure que le constructeur leur imposait de faire en pareil cas)"
[my translation] the events "
led the pilots to lose control of the aircraft (even though they were following scrupulously the only procedure that the manufacturer required them to do in such cases)"
=> Really? Let's remind that this very procedure called for (memory items):
- announcement "IAS douteuse" (Unreliable Air Speed) by the Cpt
- AP, A/THR & FD OFF
- 5° pitch up
- AND CLB power
=> wheras AF447's crew:
- didn't make the announcement nor called for the associated procedure (QRH)
- didn't select FDs OFF
(AP & A/THR were automatically shut off by the speed indications loss)
- took pitch up to ~11°
(i.e. more than twice what was required in the procedure)
- didn't adjust thrust until much later.
Scrupulous application? Huh?
So much for ALTER's credibility...
