Guys, you are assuming that we are talking about 320 or 330, but they are different and the original question was about Airbuses.
Bobrun, on a 320 if you are in Alt law then you will go into Direct Law on gear down, always. You will go into direct law with a double rad alt failure on gear down too, direct from normal law.
Dreamland, that is not the case on the 330, you will stay in Alt Law in a lot of instances.
