Interesting question.
So was there. ? A message
This plane would have been making a fully automatic approach with the handling pilot ready to take over if it went pear shape.
The facts so far are the handling pilot noted the ATS did not respond to a demand. Manual correction did nothing so at this point I guess the AFCS was ditched.
What ever the reason for the ATS and or power lever input to FADEC not spooling the engines up ,the FADECcomputer programme was unable to realise it should have powered the engines up to a min power setting.
Billy Boeing is in trouble even if in the end the Captain takes some of the blame.
