The Ins and Outs of the ADS-B DO-260B Compliance

All new Automatic Dependent Surveillance-Broadcast (ADS-B) requirements are being written to the DO-260B standard. Fortunately, Honeywell has products and solutions with ADS-B Out capabilities available today or in the final stages of development to ensure compliance with the various mandates.

ADS-B Out enables an aircraft to use precise GPS data to accurately pinpoint its position in real time and broadcast this data to surrounding aircraft and ATC situational awareness, giving pilots and ATC a better understanding of where the aircraft is in relation to the traffic around it.

ADS-B technology using onboard position reporting becomes an enabler for improved surveillance, to more accurately track aircraft anywhere in the world. The aircraft determines its own satellite-based position. This information (along with identification, category, velocity, status and other important data) is broadcast every second and can be received by air traffic control ground stations as a supplement to secondary radar or used by other aircraft to provide enhanced situational awareness.

ADS-B technology provides four distinct services:

  1. Automatic Dependent Surveillance-Broadcast (ADS-B).
  2. Automatic Dependent Surveillance-Rebroadcast (ADS-R).
  3. Traffic Information Service-Broadcast (TIS-B).
  4. Flight Information Service-Broadcast (FIS-B).


Timeline for ADS-B mandates

All aircraft operating in U.S. Mode-C airspace will be required to be ADS-B Out equipped by January 1, 2020.

The European Union Single Sky Committee has amended the previous ADS-B Out mandate timelines, proposing the following changes to the DO 260B ADS-B Out mandate.

  • Forward fit moves from January 2015 to June 2016
  • Retrofit moves from December 2017 to June 2020



Bringing ADS-B Transponders into DO-260B Compliance

Honeywell has received a European Technical Standard Order from the European Aviation Safety Agency (EASA) approving the use of its Primus® Epic Automatic Dependent Surveillance-Broadcast (ADS-B) Out transponder in Europe.


With this certification, business aircraft operators flying aircraft equipped with Primus Epic cockpit in Europe will also be able to upgrade to ADS-B in the future, saving time and money by using the improved positioning accuracy to request route changes faster, reduce aircraft spacing and fly at more fuel-efficient altitudes.

Honeywell’s Primus Epic ADS-B transponder is ADS-B system compliant with D0260B standards, which require the transponder to feature a self-aware GPS that can pinpoint accuracy down to roughly three meters. With improved GPS accuracy pilots will be able to fly safer with greater awareness of nearby aircraft. This will also serve to ease air traffic management in the coming years. 

The EASA product certification builds on an existing FAA certification for U.S. operations in place since December 2011. As well as the European certification, the Primus Epic ADS-B transponder also has product certifications in Australia and the U.S. With product certifications in place, manufacturers including Dassault, Gulfstream and Embraer are now undertaking EASA platform certifications of the Primus Epic ADS-B transponder.

Primus Epic is available on selected Gulfstream®G-series (PlaneView), Dassault®Falcon (EASy II), Embraer®E-series and Lineage, Hawker Beechcraft, Cessna Citation, and AgustaWestland AW139 aircraft.

From BendixKing® by Honeywell

The BendixKing KGX ADS-B solutions are flexible, certified and affordable. The KGX 150 series of UAT transceivers and receivers offer an ADS-B OUT certified solution with an integrated WAAS GPS as well as the ADS-B IN features of Traffic and Weather along with optional wireless connectivity. The KGX 130 offers the same capability for aircraft that already have a compatible ADS-B compliant WAAS GPS solution.
