There are 4 ways to receive weather updates and NEXRAD radar in-flight:
Method #1: Use a portable Stratus ADS-B receiver. For more info about Stratus ADS-B, please visit our Stratus information page.
Method #3: Use Garmin Connext to pair ForeFlight with a compatible ADS-B Garmin setup using a Garmin Flight Stream 110 or 210. You can learn more here on our Garmin Connect information page.
Method #4: Use Cellular data on your iPad or iPhone. This is not reliable in the air and is not recommended by ForeFlight because of the lack of reliability.
