Flying X-Plane Mobile Offline
If you do not “Pack” your route, you will need to have an internet connection at all times in order to fly the route. The app will download the minimum amount of files at the beginning of the flight, and continue to download files in the background as required as your flight continues.
Clearing Downloads:
To clear “packed” data off of your device and regain the storage space, go to the General tab of the Settings screen and tap the “Clear Downloaded Cache” button.
For more information about Freeflight and setting up routes, see our X-Plane Mobile Manual's section Freeflight.
