        5      If an aircraft carries ADS-B transmitting equipment which does not comply with an approved equipment configuration, the aircraft must not fly in Australian territory unless the equipment is:
(a)     deactivated; or
(b)     set to transmit only a value of zero for the NUCp or NIC.
Note   It is considered equivalent to deactivation if NUCp or NIC is set to continually transmit only a value of zero.

                 (ii)   the type must utilise HPL at all times HPL is available; or
(c)     is otherwise authorised, in writing, by CASA for the purposes of subsection 9B of Civil Aviation Order 20.18 as being equivalent to one of the foregoing types.
                GNSS position source equipment — standard for aircraft manufactured on or after 28 June 2012
        3      For an aircraft manufactured on or after 28 June 2012, the geographical position transmitted by the ADS-B transmitting equipment must be determined by:
(a)     a GNSS receiver of a type that is authorised by the FAA in accordance with TSO‑C145a or TSO‑C146a as in force on 19 September 2002, or a later version as in force from time to time; or
(b)     a GNSS receiver of a type that is authorised by the FAA in accordance with TSO-C196 as in force on 9 September 2009, or a later version as in force from time to time; or
