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.
2) Different seals and hoses are compatible with different
chemicals--although it would be no surprise to find that all were compatible
with biodiesel.
3) Certified aircraft/engines require fuels authorized in the type
certificate and/or an STC.

My understanding is that biodiesel is compatible with all common
elastomeric components used in diesel systems. It has somewhat
higher lubricity and detergent properties compared with petroleum
diesel.

So the first tankful might clean enough crud out of the fuel system
to
foul the fuel filter. After changing that filter, the engine should
run
cleaner.

One reported problem with biodiesel is that it gels at low
temperatures.
