How often do we autoland? Depends on airborne equipment, ground equipment and company policy. On A320 my company did not allow autolands if ILS wasn't at least CAT II certified and low visibility procedures were in force. Another A320 operator allowed autolands on CAT I ILS but no automatic rollouts - the autopilot had to be disconnected before nosewheel touched the runway. At my outfit one can expect to make 5 to 15 autolands per year out of about 500 total (depending on how long the fog season is).
There's no autoland on my current type (DHC-8 400).
