December 13, 201213 yr Just an FYI that from my perspective there appears to be an issue with the just released 1213 AIRAC date from Navigraph (all rev1). I found it when starting Aivlasoft EFB - it crashes upon trying to read in the new cycle. It looks like there is an issue with the file wpnavapt.txt, numerous airfields have latitudes of -999.0000000. Beware that that file is part of the NavData in several different add ons (Aivlasoft, PMDG, IFLY, LevelD at least). Posted on their forum, so it will hopefully be addressed quickly. Joe Lorenc
