What can I tell you? NavBlue is supposedly on the 28 Day AIRAC Cycle everyone else is on, but one of my two home fields that I operated out of IRL has both RNAV and VOR approaches. They’re in the database, Little Nav Map and other EFPs can read it in the default MSFS database, but the sim’s built in Flight Planner doesn’t recognize they exist. I can save a correct IFR plan with those approaches outside of the sim and try to load them, but if the Sim FP doesn’t recognize them as valid, they get discarded.
Your call.
