Before you answer the question, perhaps you would kindly outline your practical experience of winter operations and snow flying and what formal /paper qualifications you have to make such a statement?
Woof. Perhaps my only paper qualifications and practical experience of winter operations are that I fetch the paper for my master in the snow? Would that make you less likely to believe me than if I claimed to have a PhD in physics and fly a booted light-twin around throughout the year? Should it? If you don't believe what I write about icing, why don't you do your own research?
in view of the fact that you won't know the temperature of a cloud until you're in it, how do you know which is the "best" cloud to fly in?
You're twisting the way I chose to express that. The simple point is that the higher icing potential comes from clouds that have high supercooled water content before glaciation, not the ones that are already glaciated and shedding snow at high rate.
There are no certainties when it comes to icing, and any flight in temperatures around freezing is going to have to pay significant attention to conditions. I've not, at any point in this discussion, doubted your practical observations that snow
can pose a hazard, particularly to your helicopter. But, perhaps based on the limitations that your flight manual imposes, you seem to be extrapolating to overemphasise the effect of snow on other aircraft. There are other weather phenomena to be
more concerned about.
