Well that's roughly a meter difference in elevation in the correct direction. I suggest that you post on the fsaerodata official message board and ask them to look at both their revised stock file and the PROC file. As a test, put this file in your .../scenery/world/scenery folder:

If it doesn't work, just delete it.

Any add-on that is not up to date with the latest AIRAC will show discrepancies with fsaerodata. Also I have found that Little NavMap updates its scenery database far faster with each new AIRAC than Plan G.

Just noticed on the notes for the latest Navigraph update, it now includes support for Little NavMap. Need to rescan addons using Navigraph FMS Data Manager, and Little NavMap will be added to the list for nav database update.

 

Regarding magdev data, I also noticed this on fsaerodata's FAQ page:

"What Navaids are updated?

Instrument Approaches, SIDs Departures, STAR Arrivals worldwide. Airways, Enroute VORs, NDBs, Waypoints, Terminal Navaids, Magnetic variation, TACANs, Runway designators or heading, ILS frequencies,  Navaids frequencies. Obsolete navaids disabled."

So does this mean we don't need to use Herve Sors "Updated Magvar Data"?

When you install the newest data it will install new magvar file for 2017. Just updated mine.

Yes, just read that starting with the latest cycle (1713) fsAerodata will update the magvar file if needed! Nice! So you don’t need Sors’ file anymore!

Good news. Makes things less complicated.

Sorry guys to hijack the thread but relevant with BGl and it seems that you all know about it....I have asked on their forum and apparently the update would still work even after the subscribtion ends, i.e. I can get one month have it update to this month's navigraph and then if I do not want to subscribe let's say for 10 months I can still benefits of the up to date data, however I was wondering if you saw any backup function within the software at all in case one needs to make a fresh install.
