I would like to have some kind of table with the standard fuel consumption for all types of aircraft. Or that there was such a point in the general information about a particular type of aircraft.
This is necessary to customise the aircraft model in my simulator. I need to know the number to aim for when customising (in my case aircraft.cfg).

That would be nice, not sure where we would get that information. We do have some standard formula's to calculate what an average flight should take, but its really just to catch cheaters who are using too little fuel These use the max fuel capacity of the aircraft and the range with max fuel to create a base line and then use data from past flights on the system to calculate what an average flight should be using a linear regression formula. But I don't think that is what your looking for.
