of course we know it was a dual coupled approach and so 'autoland' ready. If this was not the ' fact' the investigation board is undermining there own preliminary findings. If this crash has a relation with the RA's then it was a dual coupled approach.
If it was then a dual channel autoland, which would require 2 functioning Rad Alts, and one was obviously giving erroneous readings for the best part of 2000 feet, then the autoland should have be discontinued to a manual ILS (20/20 hindsight I appreciate, and there but for the grace, etc)
