I'd like to think readers/posters are starting to realise that the much quoted '100secs' of no TL movement wasn't the cue many believe it should have been.
I liked alf's post too.
I saw the graph that showed speed & position compared to the glideslope (post 1643 maybe 4 pages back), with data from OpenATC, but there hasn't been much talk about that.
If the data is to be believed, it shows the plane following the glideslope from 1000ft down to 600ft, with the speed only dropping below Vref around the same time that the plane drops through the cloudbase (700ft).
With the datapoint spacing said to be 15s, would that suggest the 15-20 seconds after coming out of the cloud would be where thrust ought to have kicked in - and where the pilots could have started to perceive the problem? (Either by the instrument scan, or the sensory perception of the noise/attitude)
Or would the AP have been dialling in more trim before this point, and *that* ought to have been the clue?
