- Detect custom aircraft system refueling should be off
- Always fuel progressively only matters for airplanes flagged using a custom fuel system, the TBM doesn't have an default internal profile, so I don't know how is flagged in the custom profile you are using. If the airplane is fueled by GSX, it will always be fueled progressively.
- Have you selected a fuel quantity higher than the one you had on board before calling the GSX Fuel Truck ? GSX doesn't simulate "Defueling" so, if you have some quantity on board, let's say 50%, and you select 40% in GSX, the Truck will just go away, because it sees you already have more than enough fuel.
