IFATCA considers the issue of single emergency code management with ADS-B to be of concern particularly if introduced to replace radar as a sole means of surveillance in high density airspace.
IFATCA Policy is:If ADS-B is to replace radar then it shall have the same or better functionality as SSR, and this specifically includes discrete emergency codes and a SPI function. IFATCA considers the issue of single emergency code management with ADS-B to be a concern, especially if ADS-B is used to replace radar as the sole means of surveillance in high density airspace. Continued awareness of ADS-B operations without separate emergency codes and isolated SPI function is necessary. |
