Sec. 121.629 — Operation in icing conditions.
(a).........................................
(b) No person may take off an aircraft when frost, ice, or snow is
adhering to the wings, ............................
That argument could be made. If you look at the video you can see that they cleared a portion of the wing to see if it was adhering. Gravity is not the same as adhering.
We in the US, live in the world of the lawyers. Unfortunately. Before the glass viewing, button pushing, ipod wearing, back pack crowd jumps on me for being an idiot, tell me when the last air carrier accident was due to snow sitting on the wing.
Do not go with Air Florida. That had nothing to do with ice on the wings. They produced lift and flew. NTSB.gov. Learn something. I will give you a clue. EPR.
Don't get me wrong, I follow the same lawyer rules you all do and waste tons of deicing and anti icing fluid a year. Just don't be so quick to judge from afar, when the proof in in the pudding. It flew. The miracle is not because it had snow sitting on top of the wing, the miracle is that it is an airbus and it flew.
