Light a/c not my field but I would just like to know how you chaps heat your B & Q sprayed de-icing fluid?
The Winter operations training I do every year clearly state that it is the "HEAT" in the fluid that removes the ice, the fluid then remains unfrozen due to it's chemical properties providing the holdover time etc.
Just askin' as some of the comments above (to my non-light aircraft experience) are just plain scary.
