Dave,
I'll keep this short :-)
- The Gatwick Aviation Society (GAS) maintain an online database for free - nice people manually updating the database. They try very hard, but it's never going to be 100% accurate for obvious reasons :-)
- RadarBox comes with a huge database built in, just in case you never connect to the internet. This is the NavData.db3 main database.
- Run RB without an internet connection and it's the data in DataBase.db3 you will see. This data is also written to the separate MyLog.db3 database for when you use MyLog
- Of course, the NavData.db3 database was out of date the moment it was released - for just the same reason as the GAS database is never up to date - things change!
- If the aircraft details are not in NavData.db3 then the aircraft data line will be missing most of the details.
- If you run RB connected to the Internet and the aircraft details are missing from NavData.db3, and they are in the AirNav Server database - which is regularly populated by the GAS database - then NavData.db3 will be auto-populated and the aircraft details will appear.
- Disconnect from the internet, and all those new records in NavData.db3 are still available to you :-)
Clear as mud?
