First off, I'm not questioning your decision at all--if you're not comfortable with something, don't do it.

Reading your other thread, though, it looks like you have had some run-ins with your CP/DO before on this same issue. If you've cancelled a flight and they got pissy about it, then you were most likely on their radar.

It sounds like there's some ambiguity between what the manufacturer, your AFM, and holdover tables say. If there is a published prohibition on flight into light freezing rain somewhere, then it's ludicrous that they're giving you any crap. If there's only a prohibition into "freezing rain", then I understand the confusion because your holdover tables seem to allow for it. If all your AFM says is "no flight into SLD conditions", then you probably are authorized to land in -FZRA (I don't think light is necessarily considered SLD).

At my company, the CRJ is approved into -FZRA, -PL, and a number of combinations and intensities of various precip types that are confusing as anything. They recently published a new holdover table that has a separate table of types of freezing precipitation and states clearly whether we're authorized to dispatch to, takeoff into, and land into them. It's incredibly useful and takes some of the ambiguity out of the situation.

I understand why your DO/CP doesn't think that a letter from Dornier Support Services is enough to prohibit flight into -FZRA, but I bet that it will help you keep your job.

I think that you made the correct decision based on the ambiguity of your AFM. Captains and I have refused a couple of airplanes that theoretically were "legal" but were a bad, bad idea, and the company was mostly supportive of the decision. It sucks that they're taking this stance with you. Good luck, let us know how it turns out.
