Automatic Dependent Surveillance-Broadcast (ADS-B) is a component of the Next-Generation (Next Gen) Air Transportation System. ADS-B is an advanced surveillance technology that combines an aircraft's positioning source (GPS), aircraft avionics, and a ground infrastructure to create an accurate surveillance interface between the aircraft & aircraft traffic control. ADS-B provides consistent position accuracy regardless of the aircraft's range from the receiver.

The improved accuracy and update rate of ADS-B is a critical segment of the NextGen infrastructure.

The FAA has determined that it will be necessary for all aircraft operating in specific airspaces to be equipped with ADS-B Out by 2020. A nationwide infrastructure of ground stations is scheduled for completion during 2013.

As of June 2010, only ADS-B Out is being mandated. ADS-B Out provides the ATC with real-time position information. ADS-B In is the aircraft's ability to receive and display other aircraft broadcasted information as well as the services provided by the ground stations.

ADS-B requires the use of a Positioning Source. As of June 2010, any positioning source is allowed; however, WAAS is the only positioning service that provides the equivalent availability required.

A Broadcast Link is also required for ADS-B functionality. There are two available options: 1090 MHz Extended Squitter (ES) or Universal Access Transceiver (UAT). FL 180 (the lower boundary of Class A airspace) is the ceiling for operating an aircraft equipped with UAT only.

ADS-B will eventually provide weather services, air traffic information, terrain maps and other flight information services for all pilots through satellite based data and ground stations. In accordance with NextGen, ADS-B will provide benefits that address some shortcomings over other, existing surveillance systems.

Some of these benefits include:
  • Air-to-air surveillance capability
  • Surveillance in remote areas where radar coverage is unavailable
  • Real-time traffic information for aircraft not equipped with active traffic systems (ex. TCAS, TAS)
  • Reduced separation between aircraft due to sharing of flight information between aircraft
  • Better predictability in departure and arrival times

    Ultimately, ADS-B will allow aircraft to fly at safe distances from each another.

Although some manufacturers call out specific transponder antennas in their installation manuals, almost any transponder antenna can be used with any transponder. Various models are available based on the screw hole pattern desired and the speed & drag considerations based on the aircraft type.
 


For smaller general aviation aircraft, Southeast Aerospace recommends the stub type AV-22 or CI-101 antenna.

 

 

For medium to larger aircraft, Southeast Aerospace recommends the blade type CI-105 or AV-74 antenna.

 


Ultimately, it is the responsibility of the installer or installing agency to determine what antenna is suitable for the aircraft application.

 

 

 

First of all, your equipment should be properly installed with setup, including transponder & GPS. Next, you must be receiving a signal. Finally you should check to make sure your software has been upgraded to version 1.4 or 1.3. If everything is functioning properly, you are receiving a signal & have the proper software - TIS should be working.

If you software has not been upgraded, please contact Southeast Aerospace for your free software upgrade.

While the TT21 is certified to TSO C166B, the TT21 is a Class 2 transponder and therefore does not meet the power output requirements for FAA transponder and ADS-B regulations. Currently, the FAA requirement for United States airspace is that ADS-B Out is in conjunction with a Class 1 transponder. Other ADS-B environments (ex. Europe and Australia) do not require a Class 1 transponder.

It is recommended that TT21 owners transition to the higher power, Class 1 TT22 to fully comply with the FAA ADS-B performance requirements.
The Mode S aircraft identification code is listed on AC Form 8050-3, Certificate of Aircraft Registration, as the International Civil Aviation Organization (ICAO) Aircraft Address Code. If the aircraft registration does not contain this information, aircraft owners with a Mode S transponder can obtain an aircraft identification code from the FAA Aircraft Registry in Oklahoma City, Oklahoma. This may be accomplished by writing to the following FAA address:

Federal Aviation Administration
Aircraft Registration Branch AFS-750
P.O. Box 25504
Oklahoma City, OK 73125-0504
