You are right, Bruce. Fuel consumption seems to be higher than factory standard for our An-148s. Maybe it's because they have had quite a severe winter yourney across Siberia already

Seriously now: I do want to get into this a little deeper after the St. Patrick's Day Fly-In. maybe create an updated installer with modified aircraft.cfg as you are already experimenting with. On the other hand: fuel consumption is very high on climbing, reasonably high during cruise, and astonishingly low during descend. Or at least that's my experience during the Trans Siberia Event. Also, I noticed then that my descend planning was always off by a good margin. So what I want to do first is to fly a semi-long-haul "on the numbers" (any deviation from optimal performance numbers will cost extra fuel), and with a prolonged descend phase. That will save the difference in fuel usage between cruise and descend for the prolonged time, and will make that I do not have to use the speed brakes during descend to actually make it down to the runway without orbiting or descending in a holding pattern.
As far as Flight Logger is concerned, there is no problem if you stop half way for refuelling. In fact you can even shut down your engines, save the flight, come back the next day, load the flight, and take off again after refuelling. The "on groud" state "knows" if that is at your destination or not, and only after shutting down your engines at your destination will you be able to PIREP the flight. You could fly an entire world tour between DEP and ARR, as far as Flight Logger is concerned. It will still be recorded as a (multi-leg) single flight.
You can even view your flight critique per leg, or as an overall performance ( pushbutton "Record Flight", Tab "Propilot").
