Beware those airports with an unqualified terrain profile during the last 100ft of the approach. Although autoland systems are tested for problems caused by ditches, walls, etc there are limits as to how much a system can take.
ATC must be informed, but they may not be able provide any protected area. IIRC there was a serious incident involving an MD 80 practice auto land at Gatwick when a departing aircraft overflew the LOC aerial and caused a major LOC / roll disturbance.
411A obviously hasn’t flown an Avro RJ autoland!
