Flight Information Service - Broadcast (FIS-B)
The Flight Information Service - Broadcast (FIS-B) provides updated weather and flight information directly into the cockpit via the ABS-B system. It operative over the UAT (978 MHz) data link.
Some weather products than can be received via FIS-B include:
- Graphical AIRMET
- Center Weather Advisory (CWA)
- METARs / TAFs
- Cloud Tops
- Icing
- NEXTRAD Radar
Be aware that data received from FIS-B can be as much as 5-15 minutes old by the time it is displayed in the cockpit. Never use FIS-B NEXTRAD data to circumnavigate a thunderstorm.
Traffic Information Service - Broadcast (TIS-B)
Similar to FIS-B, the Traffic Information Service - Broadcast (TIS-B) provides position of nearby traffic to the cockpit via ground stations. These ground stations aggregate traffic from ADS-B Out sources (978 MHZ or 1090ES transponders). FIS-B receivers can operate on either 978 MHZ or 1090ES.
- TIS-B is only available below 24,000 feet.
- You will receive TIS-B targets that are within a 15nm and +/- 3500' of your aircraft
