Well I have had a poke around (blind man in the dark scenario) in the jbsim
turbine code and found the fuel flow value is already and always generated
on a per second scale, And also Oil Temp ,another goodie i was looking for,
from there is appears on the *fdm/jsbsim/propulsion/engine* property tree.
I am not sure how it gets over to the engines prop tree and multiplied to
hours in the model but I will take it from the fdm for now.
And it looks like JBSim is taking the fuel from the tanks as well.
I have to much to learn here.
