The defrost pattern would probably be only a couple of small circles before the flow cooled to where it was colder than the windscreen. You really do need to defrost a wider portion of the windscreen, and only the plenum would do this. If one needs more defrost air, a fan in the duct feeding the heat/defrost valve would be one solution. Question for all on this list: When has anyone had to use defrost while flying their Lancair? IMHO there are not many :-)) Cheers, John On Wed, 30 May 2012 16:05:22 -0400, wrote: > > QuestionWouldn't putting these fans in blowing up help with the > defrost.
