Flying the A320 now, so really don't think that would be a better approach to how we do it (pun intended). When I flew turbo-props, doing non coupled approaches, I did like it. The PF, for us the FO, would be concentrating on flying the approach on instruments, and if nothing happened by the time he reached the DDA/DA, he would continue to fly, and at mins would call "Go Around" and fly the missed. The PM, in our case the PIC, would scan in and out, and if it was clear a successful landing could be made, he would say "my controls, landing", and land the plane, with the FO becoming PM. For me it seemed to work better than to be scanning instruments, and hearing "runway", and having to look outside searching for runway while hand flying. We flew a lot of non-precession approaches where the runway would not be 200 feet below and 2/3 of a mile straight ahead at mins...
