I can’t find any explanation about why does some airplanes have a different fuel consumption depending on altitude. Some aircraft like the citation have a fixed fuel burn at power and doesn’t change after climbing comparing to other aircrafts. What’s the explanation and how to calculate a good fuel usage ?
Because the higher you go, the thinner the air becomes, and the more power the engine have to make, and more fuel gets burned.
Hope this helps

The lower you go, the more fuel you save
Most of this has to do with the age of the models - the citation is rather old, so it does not have a realistic fuel burn model.

Actually a plane burns less fuel at higher altitudes
and thinner air creates less drag also increasing efficiency
