I wonder how we deal with this with the next release- I'm sure a whole lot more users will complain about the stuck while launching FGFS. By printing a message like 'Building database during first startup' on the screen? By including the binary nav data with the release? Doesn't look like a

Hello, I thought today it would be nice again to have a flight in FGFS, since I found some spare time. Updated FGData, download the latest Jenkins build #726 for win32 and launched it. Since a whole while now, a bit more than 30min, it is stuck at Loading navigation datas. And I'm still

Hi Fred, I know some people erase the content of the folder having autosave.xml. This folder is now used to host a navigation data cache. The first time, a SQL database is built to speedup future start. If this cache is erased every time, it defeats the purpose of the cache and make the

I've just pushed a large change to next, which adds a binary cache of most of the navigation data. The cache is stored in FG_HOME/navdata.cache, and rebuilt if the timestamps on any of the data files change (apt.dat, nav.data, fix.dat and so on). When the cache needs to be rebuilt, startup will
