We all know that taking off with ice or frozen precipitation adhering to the aircraft is a no-no. But when exactly would you say that the snow accumulation has "adhered"? More importantly when does the FAA say that snow has adhered to the aircraft?
In situations where there is a very light flurry, and there are a few snowflakes on the wing that will blow off at 10kts of groundspeed, this is obviously not adhering to the wing. In contrast, if you had been sitting for a couple hours in a snowstorm, there will most definately be snow adhering to the wing.
Where do you draw the line during a light snow fall and get deiced? I guess what I really want to know is where does the FAA draw the line?
