My friend flies the A320 and when I asked him about landing with one TR locked out he said training never really covers that sort of thing so he didn't know. He said a lot of pilots don't understand some of the automation of the Airbus so even check pilots don't always get it right. Hopefully the DFDR and CVR will tell if changes need to be made. I only flew Boeings so always got what I asked for and nothing else
This is quite disturbing, but I won't give it credence unless I hear it directly from pilots who flie the aircraft
