This aircraft really is just equipped with a "get out of icing conditions" system, despite being certified for continuous flight in light to moderate icing conditions.
Oktas8,
That is all it ever is, there are some serious misunderstandings about what icing certification means.
I agree with the comment about icing conditions in SE Australia, in many tens of thousands of hours, the only time I have had to use wing anti-ice on a large aircraft was exactly there, around YMML.
What is often forgotten is that the freezing level in much of US/CA/EU etc. in cold weather is below ground level, so the worst looking weather is not necessarily the worst for airframe icing.
But, lots of nice wet cloud and a freezing level of 10-15,000 ft, who would want to be a night freight pilot in a Metro.
Wherever you find it, get out of it ASAP.
Tootle pip!!
PS:
Brisbane-Gayndah corridor contained some of the most severe CBs to be found anywhere...been there too...
Who ever said that has never been around the West African coast, anywhere from Luanda north, for too many nights per year.
