SUR 6.2 ADS-B: SINGLE EMERGENCY CODE MANAGEMENT

For the 2007/08 Work program, TOC was tasked with investigating single emergency code management with ADS-B. It was documented in the 2006/2007 work program that the problem exists and that further research would be needed. The working paper describes the hardware issue, dealing with the exact problem and why. It then begins exploring ICAO for support in relevant documentation and concludes with the implementation issues in Australia.

TOC considers the issue(s) to be of concern particularly if introduced to replace radar as a sole means of surveillance in high density airspace. For these reasons, TOC has decided to propose draft recommendations, to provide guidance for when this technology is introduced.


IFATCA Policy is:

If ADS-B is to replace radar then it must have the same or better functionality as SSR, and this specifically includes discrete emergency codes and a SPI function.

In non-radar airspace DO260 ADS-B is considered an acceptable interim solution provided global procedures are established for handling single emergency codes and potentially decreased SPI functionality.

That ICAO establishes a global position and recommendations on the management of ADS-B operations without separate emergency codes and isolated SPI function.
