Problem fixed. It seems that it was a French language Problem. I created a new user, than re-created de database.

Tim, the path looks OK. See attached file. Any other suggestions?

I noticed in another post "Airspace input error while building database"  that it is now possible, with version 3.2.0.144, to have Airspaces with X-Plane 11. I have re-build the database but still no Airspaces.

My usa.txt file is located in "X-Plane 11\Custom Data\airspaces\.

Am I missing something?

Thanks for the information. I look forward to seeing this change.

Please help.
I just installed Plan-G v3.1.4.129 for X-Plane 11 on Windows 10. Everything works fine except the airspaces in the USA. I have checked and the file usa.txt is in the directory "D:/X-Plane 11/Resources/default data/airspaces".

How can I fix this problem?
