Firstly, credit where it is due, and hats off to the crew for a safe outcome.
Video looks like some serious pea soup. Would be lucky to be 800m I would think. No wonder the pax had been given the brace command. Makes sense to me. I look forward to finding out how they pulled it off safely but I am going to guess like everyone else has been, and agree with the previous poster who said dial up the rnav which will give the pseudo glideslope to the threshold.
I wonder if there will be an RNP approach implemented in Mildura at a later date now that the test flying calibration has been already completed
