Not sure where you get that grossly incorrect piece of information. Microsobo are partnered up with NavBlue, who publish charts. They’ve updated the AIRAC data every month since the sim was launched. Originally, they did it a bit late with one of the regularly scheduled updates. In November, they started issuing them as separate updates. We’ve had 2 standalone AIRAC data updates so far. Both those were a bit late as well, but they came out.
Now, I don’t disagree. Navigraph data is far superior to what is in the sim. I’ve been using it and I wouldn’t even dream of switching back to the dumpster fire that’s the MSFS stock data. There’s so much missing data, and so much of the data that’s there is just plain wrong.
