Lynn, could this explain phantom airspace warning I was getting in my LX9000 using your CUB airspace files? I was getting alert that I am inside class B/C Airspace’s that were at least 10 miles away. This happened with more than one airspace, always in the same areas. I assumed it was LX9000 bug, but the LXNav folks never identified the issue.
in any case, thanks for identifying and fixing the issue and many thanks for your service.
