Path looks correct. Did you change #code = exam line into code = exam, to make the airport appear at the bottom of the airport menu? Also, rename the filename to make sure it isn't overwritten.
Yep (am an old s/w engineer and used to INI file formats). Did not rename it though, but also did try the FACT airport file from the downloads zip. Will try again.
Love the emergencies by the way - missing squawk codes though, but my phone screen has very limited real estate space, so it is all good for the tight fit.
