Quite easy. You push the Autoland button.
Get to Mildura, it's socked in. Now it's a Mayday... go to ADL and autoland! The airport's not set up for LVPs/LVOs but who cares? The aeroplane doesn't know that. Demand ILS protection and the autoland will be better than what happened... a bee's whisker from a couple of hundred bodies strewn over the airport grounds at Mildura.
