the aircraft was initially high and fast on the approach and at about 2,000ft above ground the throttles were pulled to idle
the authrottle went to "retard" mode and the throttles then stayed at idle for about 100 seconds during which time the speed fell to 40kt below reference speed
the aircraft descended through the glideslope with the captain talking the first officer through the before landing checklist
the stick shaker activated at about 400ft above ground and the first officer increased power
The approach should be considered to be fully stabilised when the aeroplane is:
a) tracking on the required approach path and profile; and
b) in the required configuration and attitude; and
c) flying with the required rate of descent and speed; and
d) flying with the appropriate power and trim.
But in the interest of flight safety, approach vectoring at AMS should be looked at. If it turns out to be blameless, fine. But it should not be discarded as a contributing factor from the onset.
From 2000' with idle power and trying to regain profile, is the mode change to "Retard" signalled by anything other than a caption on the PFD? If not, could this be overlooked because of
expecting normal A/T response and high work load trying to stabilise the approach and talking the F/O through the BEFORE LANDING checklist at a very late stage?
