There are really three of issues (that I can recall) he
1) A diesel will run on any hydrocarbon fuel that it can pump and meter.

with biodiesel.

certificate and/or an STC.

4) Biodiesel supposedly thickens at temperatures that pilots fly in.


As does regular diesel fuel. The stuff will gell up here in winter so
I'd expect to see biodiesel durn near turn solid.

Though it can be corrected with additives, I would rather have heated
wings (thus tanks) to avoid additives and gain de-icing capability for
the same feature.

Additives are much more reliable so you have (how ever many tanks)
less items to fail in winter.


Has this been done before, or do de-icers only heat the leading edges
of the surface?
