Thanks for the comment in post 837.
So they ignored all of this or left it too late, and flew into the ground - all 6 eyes????
Actually not, really. The way I see this scenario is that the alerts you mention, except perhaps the stall warning, would only have been triggered when the situation had already become serious. Assuming the AP held the aircraft on the glideslope, presumably only the speed tape and pitch trimmer could have given clues to the crew before the stall warning activated... or ?
The data indicates the aircraft decelerated by, on average, 2 knots per second during the 15 seconds after passing 650 ft altitude while remaining on the glideslope. In other words from Vref to stall speed in just 10-15 seconds!
The nasty thing in this kind of thrust-deficit situation is that the speed decay develops slowly and can be hard to notice, but then gets progressively quicker as AoA and drag increases. It appears a little peculiar that the EGPWS does indeed have a sink rate alert, but apparently no deceleration alert which might have provided early warning to save this aircraft from losing airspeed. Please correct me if I’m wrong.
