Automatic Dependent Surveillance – Broadcast (ADS-B) is the backbone of the next generation ATC system, and is the most rapidly-evolving portion of the avionics industry.
ADS-B "In" Receivers offer their users access subscription-free Traffic and Weather.
The optional portion of ADS-B is called ADS-B "In". Instead of just an ADS-B Transmitter, the aircraft will have an ADS-B Transceiver (or Transmitter and Receiver). This will allow the aircraft to receive Traffic and Weather information from ADS-B.
The Traffic information is called Traffic Information Services – Broadcast (TIS-B), and it shows you the traffic ATC sees. This is a combination of all available position information, including radar and ADS-B.
The Weather information is called Flight Information Services – Broadcast (FIS-B), and it actually includes more than just weather. FIS-B broadcasts a range of aeronautical information products from the FAA and weather products from the National Weather Service, including:
- National NEXRAD - Continental United States Next Generation Radar
- Regional NEXRAD - Regional Next Generation Radar
- Graphical AIRMET - A user-friendly AIRMET
- Winds & Temperature Aloft
- Cloud Tops
- Center Weather Advisory
- PIREP - Pilot Reports
- SUA Status - Special Use Airspace status
- AIRMET - Airmen's Meteorological Information
- Convective SIGMET - Convective Significant Meteorological Information
- SIGMET - Significant Meteorological Information
- METAR - Aviation routine weather report
- SPECI - A Special METAR for fast-changing conditions
- D-NOTAM - Distant Notice To Airmen
- FDC-NOTAM - Flight Data Center Notice To Airmen
- TAF - Terminal Aeronautical Forecast
- AMEND - An amended TAF, for chaning conditions
These ADS-B "In" Receivers offer tremendous value for the information they provide. Portable units offer even more value, since they do not require installation. They can send their information wirelessly to a portable display. This display is likely larger, sharper, and easier to read than any display installed in your panel.
We believe it is important to choose a dual-band ADS-B "In" Receiver. Other aircraft will be transmitting their position on both the 978 UAT and 1090ES frequencies. A dual-band receiver is able to capture and provide all this information.
