ADS-B In

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.

ADS-B In

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
• Lightning
• Turbulence
• Icing
• 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.
