Enroute Fueling The use of enroute refueling – landing at an airport not noted in your Bid and refueling to extend the range of your aircraft – is not permitted. You will be required to submit your flight and it will be treated as a diverted flight. You can read more about the diversion system by clicking here. smartCARS 3 and FlightTrackerXP does not support the ability to conduct enroute refueling and is the reason we do not allow it. You will be forced to submit your flight by the application.
