If the auto-pilot isn’t doing what you want, punch it off.
Punch it off anyway. The computer doesn't need the landing.
After awhile, punch off the autothrottles too. I had a captain ask if I was going to do this once - nice calm VFR day landing. I looked suprised and he said, "You DO know how to fly, don't you?"
A/T's are deferrable - yet I've seen maybe 4 guys do an A/T-off landing for practice at FDX.....
