Then the Captain Sim is a bad model and unrealistic with regards fuel usage. Unless you make adjustments, continued use of the aircraft at this low level of fuel consumption may result in further flights being flagged and reviewed as cheat flights. If you need help with the aircraft.cfg to adjust fuel consumption I would suggest you search the forums and maybe post requesting help from another Captain Sim user.
