Wrong, Microsoft Flight simulates the whole world. You can even convert the FSX world to Microsoft Flight. Wrong, there were airplanes with navigation instruments. Wrong, the weather implementation was way better than the weather implementation in FSX...

In my experience, migrating a SQL database is really easy, so maybe it will be less of a problem than you think.

The engine belongs to Dovetail Games now.

You could try increasing the LodRadius:

I believe the progress was stored on the Microsoft Flight servers with GfWL, so the Flight Toolkit implemented its own savegames in NonGfWL mode.

You only need to append /a to the usual command: <Path to Flight Toolkit>\ContentConverter.exe fsx /i:<path to FSX folder> /o:<Path to temporary folder to convert the assets> /a

The GfWL servers are still up as far as I know. Even multiplayer should still be working. Uptime might be less than 100% though because newer games obviously don't use GfWL anymore, so I doubt they spend a lot of time on maintaining the servers. Regarding the Flight Toolkit problem, you could also try this installer: https://www.microsoft.com/en-us/download/details.aspx?id=35

Which dll is missing? You are probably missing certain Visual C++ redistributables.

You could install the Flight Toolkit which removes GfWL from the game. Your ingame profile is probably gone, though, because the Flight servers had been shut down long ago.

Here are the links: The base game gives you access to Big Island. If you want to fly in the rest of Hawaii and Alaska, you should install the Flight Toolkit where you can download these addons. There are also community mods available as addons.

The game still connects to Microsoft's own multiplayer servers. By the way, I also just played the game again with the Fall Creators Update being installed on my PC, and everything still works fine here including cockpit views.

There are log files in %userprofile%\AppData\Roaming\Microsoft\Flight. Maybe the game reports the error in ContentErrors.log. You need GfWL mode for multiplayer.

Yes, you can operate the GPS buttons with your mouse in those planes that have a cockpit. I don't think there are keybinds for them.

You can't buy it anymore since the store has gone down, but you can download it for free with the Flight Toolkit: http://flighttoolkit.com/

This error seems to occur when the Microsoft Visual C++ 2010 Redistributables are missing. So your best bet is to try and install that.
