ForeFlight Mobile supports in-flight weather. There are 4 ways to receive weather and NEXRAD radar in flight:
Method #1: Portable ADS-B
Use a portable Stratus ADS-B receiver. The following are supported ADS-B receivers:
-Sentry: The Sentry unit is an ADS-B receiver and it has a 12-hour battery, an internal GPS receiver, and a backup attitude indicator. You can learn more on the Sentry information page.
-Scout: The Scout is a lightweight, portable ADS-B receiver that is powered through an external battery or by connecting to your aircraft's power through a USB port. It receives ADS-B traffic and weather. It has no GPS. You can learn more on the Scout information page.
-Stratus: For more information about Stratus ADS-B receiver, please visit the Stratus information page.
-Garmin: The Garmin GDL50 and GDL 52 ADS-B receivers work with ForeFlight. You can learn more on the Garmin Connect information page.
Method #2: Panel ADS-B
Use Garmin Connext to pair ForeFlight with a compatible ADS-B Garmin setup using a Garmin Flight Stream 110, 210, or 510. You can learn more on the Garmin Connect information page.
Method #3: XM
Use a portable XM receiver to obtain weather in ForeFlight. The following receivers are compatible:
-Garmin GDL 51 or GDL 52: Garmin's portable XM receivers are compatible with ForeFlight. You can learn more on the Garmin Connect information page. Requires ForeFlight Mobile v10.2 or later.
Method #4: Cellular
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. Also displaying Radar while connected to Cellular data can use 150-200MB/hour of data.
