The following is from the "new AC" on ADSB:
AC 21-45 v2.1 APRIL 2014
AIRWORTHINESS APPROVAL OF AIRBORNE AUTOMATIC DEPENDENT SURVEILLANCE BROADCAST EQUIPMENT
and at:
APPENDIX D
ACCEPTABLE EQUIPMENT COMBINATIONS
1. The equipment combinations listed in Schedules 1 and 2 are not exhaustive, and are a historical record and not subject to further update. The lists were compiled from data obtained from individual applications to Airservices Australia by operators wishing to be included in the ADS-B separation services.
2. Following legislative changes and technical review of the performance of existing transponder combinations Schedule 3 lists those combinations that are no longer acceptable for use in Australia. This list is not exhaustive, and is a historical record and not subject to further update.
3. Aviation Communication & Surveillance Systems (ACSS) XS-950 transponders are not acceptable unless software modification A is incorporated
