Considering RVR 75m and rwy in sight as stated,for sure you are below 200ft RA,so if AP(s) disconnects you get the AUTOLAND warning light flashing.If at any time you have the autoland light flashing, Go around is the only option according to the books.Unless you have fuel leak or any other very critical malfunction which is again based on airmanship and pilots discretion.To answer the question, in our company,the norm is GA.Obviously,A320 family.
