I'm guessing that neither airline would attempt to takeoff from Mildura with diverted passengers on board?
Their respective performance departments would assess it and provide takeoff charts.
One of the problems with BOM and Ozzie Govt spending cutbacks is that there are less local experienced people doing the forecasting.
That explains an awful lot about the state of forecasting in this country. If this is indeed a "bad fog season" then it is even more important for the BOM to be more conservative with their forecasting. For them to miss the fog in Adl is unfortunate but to then also miss it for Mildura is borderline incompetent.
Well done to the crew. I can't imagine the thoughts going through their mind when they realized that they would have to do an improvised autoland with a chance of it not being successful.
I'm also interested to know if the airport authorities activated their emergency plans and if the landing had not been successful, if emergency vehicles were at the airport.
