You can see it correctly gets the name of the airport, but not the ICAO, and I can’t select runways or parking. Manually searching for K09 and setting it as departure puts me back on the runway but blows the whole flight plan away.
Holy moly - I can’t believe I missed that! Simbrief requires you to manually type in your departures and arrivals and it puts a “K” before any three character airport code… and manually editing that K out fixes it!
Now to find a flight plan generator that doesn’t do that.
Doing a bit more research, it sounds like K09 and KK09 are sort of interchangable - I wonder where a more informed person than I would point the finger: should simbrief not add the K, or should FS2020 be better about interpreting both K09 and KK09?
