So I started using little navmap, however, I noticed a downside to it. It doesn’t generate a “real” flight plan. I saw someone say that they use the route provided from LNM and import it into simbrief to get their ofp. Do I need the latest nav data cycle to do this? If I don’t, can anyone tell me exactly how to get the ofp, I’m still not 100% sure I fully understood how to do it.
