As an "Owner" I will not knowingly take-off with contamination on the wings. That's just common sense, not to mention S.O.P. and the law according to the CARs...
However, I will not use a "
PR" spray just to be "seen" to do the right thing. It's a waste of time, and money, hard on the aircraft and it's systems, not to mention the environment...
I am thoroughly familiar with the WestJet S.O.P's regarding dry loose snow as well as "Cold Soaked Fuel Frost". How many on this board are also well versed?
It's all well and good to speak from experience gained in your own operations, but to chastise another Airline for operating according to it's own Transport Canada approved F.O.M. is counter-productive and pointless...
