Needs some work: you can’t build a manual route between airports with SIDs and STARs. No way to choose SID and STAR if you build a manual route (not letting the tool generate a route).
They are already there for IFR flights but not automatically selected. We have to experiment a lot to figure out the one we need. Ideally we shouldn’t need outside sources such as Navigraph for it, which becomes useless without a subscription anyway. The new AIRAC cycles in MSFS don’t match the outdated ones in Navigraph. I keep getting the weirdest approaches lately. Since this is a simulator, it should be able to offer a complete flightplan from A to B as much as Navigraph may hate it.
