Crew selection of the runway 21 ILS as an operator-approved runway for auto land, and use of the A330 auto land capability reduced the risk inherent in landing in meteorological conditions that were below the specified minima
We are approved to do practice auto lands on many Cat 1 ILS systems within Australia. Many ILS' however are specifically not approved for auto land practice as indicated in company manuals.
An example that comes to mind off the top of my head is Sydney 25 and 07, so if there is a choice of ILS setup within reach of fuel, I would get some advice if it is not readily available in your company manuals before just assuming that an auto land is a great idea.
I know that Launceston 32L and Johannesburg are specifically not to be used for auto land under any circumstances.
Notwithstanding, it may still be the smarter course of action, in an emergency, to take the aircraft below the minima and then disconnect when you are visual.
