Remember when fsx used to offer a fuel prediction in the flight planner, if only there was that option for MSFS in game, especially between flights without having to exit.
I feel that there are some limitations with simbrief that can throw beginners of course.
For example
I did a flight from Nadi to LAX, with runway 34L and it have me a star that went through the paths of the 35s (Might be the other way round) and they never lined up with ils on navigraph (RNAV arrivals did)
Bit of researching showed me basically all flights from my corner of the world (NZ) their routing/Arrivals/STARS took them through the islands off California and North of the airport for a approach onto those northern runways (gillys I think is the arrivals/STARS)
But it never gave me that option through simbrief out of the number it gives you and it doesn’t give you the full selected possible STARS which I feel can be confusing for some especially those who don’t have navigrah and can’t quite work out why their routing doesn’t match up to flightradar24
