Upside-down Y with AIRAC 2101 Rev.2

Hi Gil,
never seen that before (not here in the forum nor in the official FS-forum) and I can´t say what it mean … the question is, what else do you have installed, or do you use any addon-linker programs, …

I can´t really believe, that this is only due the navdata update. When you remove the navdata cycle, all looks good? Happens this generally, means on all airports?

Have you tried this:

Cheers,
Richard
