There is NO SANE REASON to have the engines at idle for 100 seconds on ILS final! Either plan and execute the approach properly, or GO AROUND!
But your SOP's (and most everybody's) says Stable by 1000'=spooled up right? That's less than 100 secs to TD. I know ideally it should be better- but they were
hot-and it was a training mission-they
needed the engines at idle to have any chance of being stable.
This is still a too regular occurrence (check your FDM rep for confirmation)-note- I'm not condoning it- but trainees will get TC's in this situation,TRE's will get other TRE's in that situation etc etc. The critical factor is when to bail out-push TOGA and away you go!!
That clearly didn't happen
Then the speed decayed-see earlier post!! Wouldn't matter if hand was on TL (and btw I agree)- PF is not expecting TL movement 'till on speed- which was much later.
That clearly didn't happen
Stall recovery required to be accurately flown from onset of stickshaker
That clearly didn't happen
And the biggest irony not yet mentioned- it was the
high energy approach which most likely got them close enough to the ground before fully 'mushing in', which made the crash surviveable for so many.
Do you see my point? If they lost control from 2000' at <100kts it's hard to believe there would be any survivors.
Also, the failed/erroneous RA is actually directly involved in 2 aspects of the flight-
1/ the initial speed decay
2/ the stall recovery-ie it pulled TL back to idle again compromising an already marginal recovery.
Enough from me......
