I read the report, and made notes. It lacked. Nowhere did the author distinguish between the gravity of an annunciated failure, and an undetected error, which was the case with the radalt.
Engineers designing Cat III autoland systems go to great lengths to assure there are no undetected failures that could kill people in umpteen fleet lifetimes. Annunciated errors and failures are expected and accommodated by the airplane systems.
If you look at this accident, and others, with annunciated vs. undetected failures in mind, the shading is quite different.
