The database comes from MSFS. It’s the same one that all the built-in planes use. It should work with 4V0 but gives a format error. SimBrief is the first time I saw it called K4V0, and I was just attempting that as a potential solution. From my experiences using NavDataReader, it’s not called K4V0 in MSFS, so the NOT IN DATABASE message is perfectly reasonable.
