Downloading data from the Downloads page is not strictly necessary for ForeFlight Mobile when the device is connected to the internet. The app will automatically retrieve the required data in real-time using an internet connection.
However, it is necessary to download items such as charts or terminal procedures before going offline (e.g., for in-flight use). Downloading data ensures access to critical data when not connected to the internet and improves the speed and efficiency of accessing these items within the app.
