Thanks ORH.
The thing I want to know is, if we were to be ramp checked after we've just gone flying with a forecast that indicates reduced vis due smoke, but we took a more practical approach and found sensible ways around it that we interpreted as legal, what would the FOI who's checking us think?
That's the problem I see, some FOI's take practical approaches to a law, others take it to the written word.
