Okay this might be a daft question to ask, but I want to make sure that I'm not wasting loads of time!

I have quite a few addon airports installed into FSX-SE, but I don't have them all set to active. I normally try to only have the ones I'm flying from and too active. My question is this! If I have run the make runways script and updated the database with airports not active do I need to re-run make runways script again once I turn one or two others to active?

Thank you in advance

PF3 does not see that your flight sim has enabled or not, it only reads the data provided by makerwys, so my suggestion would be to enable all, run makerwys and make a DB rebuild, then disable/enable whatever you want and do not run makerwys again.
The data might be wrong for the airports you don't have enabled, but if you don't fly there, everything will be fine. Make sure you don't have to divert to an airport that is different enough in stock and your add-on.
