wrote: One good reason not to use it would be the PVC insulation. PVC when burned gives off toxic fumes. Not the kind of thing you want in the cockpit at altitude. I know you can't use PVC covered CAT 5 cable in common air passages/ductwork like above ceiling tile because of this. We use "plenum" cable that is Teflon coated I believe. Non plenum rated cable is VM2 of FT2 Plenum rated wire is VM1 or FT1 wire. The wire I have is FT1 and VM1 rated - Teflon when heated above 600F will cause "polymer fume fever" just like PVC
