Load of bollocks, dual rad alt failure gives you direct law on gear down.
The Heineken beer advertisement featured a model aircraft, nothing about that advertisement comes close to reality. Are you this gullible to other advertisements produced by beer companies ?

Likewise another load of bollocks. No such thing as "Alpha Lock".

Another load of bollocks, the calls and FMAs are for low vis operations, the Airbus assumes each and every landing is CAT III. The aircraft does not know the visibility and cloud base.
Rad alt failure on a 777 will not do wonders for an autoland either. No aircraft I am aware of that is currently in production can do an autoland or low visibility approach to a DH without a rad alt.
