As usual your psychobabble to make excuses for the pilot and how the A/C system let him down. The A/THR hold mode may be a "trap" but as a PILOT you still have to FLY your aircraft.
It was an 8/8 blue day and all he had to do was look out the window and see he was about to land almost a mile short of his aim point and DO something about it. Runway aspect is taught in initial training and practiced many times. If you then cannot recognise you are well below the normal flight path with 4 reds as well, even though you will have monitored the A/P fly an ILS many many times, giving the ideal glidepath, then you have NO place on the flight deck of a commercial aircraft! This was BASIC piloting skills and a complete lack of them was being shown by the PF and the monitoring "Training" Captain.
The excuse of coming from the Airbus with no moving throttles, does not hold out either. If the A/THR in the "bus" does not keep the speed as you would like it, guess what you can MOVE them and many an Airbus pilot has done.
