I would like to adjust the fuel consumption rate of several aircraft in FS2004, as they are too high (even with using autopilot/autothrottle, correctly programming the MCDU, double checking all the entries and a maximum economy setting, the aircraft is still consuming too much fuel).
My question: what figures do I have to edit in the aircraft.cfg file and what is their effect?
I copied these line from the default lear 45 I am not sure which way improves fuel use I would suggest you make the orignal entries a comment by puting / at the front of the entry thus making it a remark then you can make adjustments untill you find the correct entry.
You might have to adjust the AIR file as well I am not sure. 8-)
fuel_flow_scalar = 1.0 //Scalar for fuel flow efficiency
fuel_flow_gain = 0.0025 //Gain on fuel flow
