what do you actually mean:
" Is that acceptable to the myriad of operations that take place daily in locations where snow appears during winter operations?"
are you trying to suggest, that because it snows so often and so many airplanes operate in winter conditions, a clean wing concept is not acceptable? It might even cost money and maybe cause delays?
By all respect to your ex mil, ex airline, now evaluation what ever that means -background and even claiming to have an ATPL, you should know better.
There is no option for clean wing! How farking difficult is that to understand? Why do all evaluators, midwifes, clerks, PPLs, wanna be pros etc try to prove it different?
A lot of lives have been lost because persons thought a clean wing concept is not necessary. A lot of lifes will be lost in future, because still some idiots dont learn from mistakes and try to know it better.
make it clean and keep it clean
