Whether you disengage the A/T for landing (manual) or not is up to the individual. But, MD designed this plane to land with A/T on. It goes to idle at 50´ but, as someone suggested. Yes, if you don’t feel comfortable at 50´manually take over. Now, each company can print their own SOP´s and flight technique´s. That does not alter the original idea that MD had in mind. This A/C was set up to be as fully automated as possible. Whether they (MD) got a perfect package that would be a matter of opinion!!
