hypothetical -- of course --
here is the situation, helicopter sitting in remote location, wet snow/rain falls for a few minutes, followed by a drop in temperature, causing the whole mess to freeze
BUT, you were prepared and have deicing fluid in a garden type pressure sprayer that was sitting in the cargo bay, so it is naturally cold.
you find a ladder from some out-building and merrily spray the applicable surfaces in the hopes it will remove the rough snow/ice buildup.
anybody have any experience with using COLD deicing fluid, is it allowed on helicopters, how effective was it, or what would you do in this situation ?
