We were tankering fuel this week. Had a few TYS turns, and the airplane was topped each time.

Just to show you what kind of gas mileage a turboprop gets. Leaving TYS with full fuel, the aircraft flew TYS-CLT-GSP-CLT before refueling again. This was possible due to sunny skies and no alternate fuel required. The aircraft landed in CLT after GSP with an hour and a half worth of fuel still on board.
