Hi everyone,
Still not working for me, when I pass through FL 170 the cabin altitude passes 14000 ft und the screen starts to grey out.
But i found a workaround in this Thread http://forums.x-plane.org/index.php?/forums/topic/113695-repeating-hypoxia/&page=2
However, you need to have Fly with LUA Version 2.5.1 installed, which you can get here:http://forums.x-plane.org/index.php?/files/file/35579-flywithlua-for-x-plane-11-and-10-windows-linux-mac-os-x-version/
I did exactly this and it works fine for me
