If you intend to play Microsoft Flight Simulator at any point without the presence of a high-speed internet connection, you'll need the "offline mode" pack to get started.

Whether or not you should choose to only install the base game of Microsoft Flight Simulator on your Xbox is a different question, however, and depends on how you plan to play Microsoft Flight Simulator and how confident you are in your internet. Players can choose not to install the pack on their Xbox and still play Microsoft Flight Simulator at its best quality. This automatic behavior, combined with a lack of official explanation from Xbox, may lead you to believe that the "offline mode" pack is a necessary piece of Microsoft Flight Simulator, but that isn't the case. When you install or preinstall Microsoft Flight Simulator, your Xbox will automatically begin installing both the base game and the "offline mode" pack, which together equals nearly 100 GB of raw game information.
