Thank you for the clarity.
No problems 😊
Having this info I dug around and found it is actually an issue with ORBX NA LC. I did not realize that their LC add-ons did anything with airports, but, sure enough open LC North America does.
yes, it’s a well-known fact, airports that are included in ORBX LC by them have a default base from FSX with a corrected elevation, but in P5 airports have newer data, and therefore there is a conflict...
I have not added ORBX Vector to v5 at all though I read it was made available today.
yes they did it ... but in this case they did the right thing and removed the airports included in this package earlier, it had to be done with all in the ORBX LC packs.
