The reference to Mildura is, I assume, regarding the diversion from Adelaide due unforecast fog a few years ago. Why you would divert away from an airport with a functioning ILS has been the subject of debate ever since. Airlines require strict adherence to regs. ( of course) but still pressure crew to carry minimum fuel. Such is the dilemma confronting every Airline pilot on a daily basis.
Slezy9, does it mean that forecasting is better or worse than 30 years ago? I would venture that not too many forecasters look out the window any more. Nor do they use the basic d@g f%ck detector any more.
I am particularly amused by the joker who puts a CAVOK period in the middle of the day on the TAF in Darwin during the wet season. Funny guy... And theres many more.
And dont get me started on single runway requirements.
Solution?
Use the the judgement they pay you for and keep yourself safe.
Everybody behind you will be thankful for it.
