*As a general rule, when not connected to the internet, you'll only have access to what you last viewed on the ground except for Radar and Satellite Maps. If you will not be using an ADS-B or XM receiver, to "preflight" your weather data, do the following:
A. View the Airport pages for departure, destination, alternate and other airports of interest.
B. View at least 1 of the METAR-based maps (TFRs, AIR/SIGMETs, Flight Rules, Temperature, Dewpoint Spread, Visibility, Wind, Ceiling, Sky Coverage, PIREPs, and Lightning). This will get you all data for all of these maps.
Radar maps, Satellite maps, and Imagery are not downloadable.
**ADS-B may not receive weather information on the ground as a connection to an ADS-B ground station is required.
***XM lightning is dependent upon the XM plan you are subscribed to.
TFRs IMPORTANT NOTICE: Graphical TFR information is ONLY updated and displayed if you select the TFR Map overlay while connected to the Internet, or while using an in-flight weather receiver. However, if the FAA publishes a TFR without associated graphical shape information it may not be possible for ForeFlight Mobile to show the graphical TFR on the Maps page. Therefore you should also check the Airports page, under NOTAMs > TFRs for airports along your route, and contact FSS or ATC to confirm that your route does not cross any such TFRs
