Never said not to spray...whatever, I'm out.

You don't know your own job. Maybe you should reread your regulations, tough guy.

121.629: No person may take off an aircraft when frost, ice, or snow is adhering to the wings, control surfaces, propellers, engine inlets, or other criticalsurfaces.

Show me where it says that if it's snowing, I have to get deiced.

You "might" want to read your SOP. Or not......

Anybody here taken off with a clean, non-deiced, cold-soaked aircraft with light snow occurring and ambient temperature below freezing? Check on the walk around, check before takeoff. Nothing adhering, good to go. It's a lot more explaining if someone calls you on it.

The vast majority of us just de- and anti-ice to avoid scrutiny. Screw it, we're not paying for it.

I am very familiar with my SOP. Still says adhering.

Actually you're wrong in this. Like CB said, "adhering" is what our winter ops says.

Most SOPs and FOMs give one plenty of rope, and will even show you how to knot it.

"When the aircraft's critical surfaces are not free of frozen contaminants, or it cannot be determined that they are free from contaminants, the PIC notifies the station that ground deicing is required"

The paragraph immediately preceding the above paragraph suggests using the jetbridge or terminal to determine that "ALL" surfaces are free and clear of contaminants.
This info was gleaned from the SOP, Ground Deicing Program and FOM.

In essence to satisfy the requirements for our airline, during active icing precip, it would almost be impossible to achieve. Add variable intensities and you are rolling the dice.

Not sure who you work for, but for Skywest refer to the Ground Deicing Program Manual S.P. 2800 Chapter 4, 5. B. 2.
I would bet if you work for another operator there probably language buried in your manuals detailing how to knot your rope as well.

So actually, for Skywest the above chapter and verse is controlling and if you work for us you might want to reference the quoted chapter and get up to speed on your job. If you work for another carrier, a little research might be enlightening.

Not sure who you work for but I refer to the manuals, FOM and SOP that my company provides. Most companies SOPs and manuals are more restrictive than the FARs.
This isn't about who's right or wrong, its about doing it correctly.
