Yes, Duncan and Ian, there is an idea I had for a long time but haven't had
a chance to try it out. It is extremely simple but would only be of interest
to those of you who have that ducting shroud over the top of their engine.
The temperature under that shroud is 32C degrees above oat.
All you need is : two aluminum flanges, one eyeball vent, four nuts and
bolts four rivets, and a piece of scat tube.
One flange is riveted on top of the port side of the shroud , first making
a hole in it of course, the second goes on top of the footwell next to the
vertical firewall, and is bolted together with the eyeball vent on the
inside. The vent is difficult to reach once you are strapped in, but is good
enough for me.
Tha vast majority of builders don't need extreme heat, and I can't afford to
fly in the middle of winter (hangar space needed etc.) , but there is a need
for cabin heat on cold days and at altitude.
I don't think the PFA would have a problem with that mod. It is all clean
fresh air and no liquids.
