Having read some of the "professional" answers in this tread, I can only conclude that it is a miracle that not more aircraft are stalling and falling out of the sky when they depart covered in "dry" snow, using "different" procedures and "different" regulations.
Getting away with it doesn't mean it's safe. I think there must be a lot of fair weather pilots out there (Miami Air; Lets taxi a bit closer to that jet blast so we can melt the snow off).
I know who I prefer to fly with. Those pilots who fear the weather.
Well done, LTD!
