I see nothing in your post about the source of my question. Perhaps de rigeur in an accident report, but this is about discussion.
PF input a deliberate and singular ND (no Mayonnaise) one half second before hearing the STALLSTALL, then a deliberate NU at which time the Warning ceased.
Interesting? No?
"What was that?"
My continued thesis is that the aircraft came to grief because the recovery was foreclosed by immediate and exaggerated handling, which was in most cases the reverse of what was indicated to the pilots.
That an aircraft can come to grief from sub standard instrumentation and seemingly random handling is cause for a concern perhaps more in depth than a data sheet?
Not a report, a discussion....
