 (a) having a certificated MTOW above 5 700 kg; or
 (b) that is capable of normal operation at a maximum cruising true airspeed above 250 kts;
  the transponder's receiving and transmitting antennae must:
 (c) be located in the upper and lower fuselage; and
 (d) operate in diversity, as stated in paragraphs 3.1.2.10.4 to 3.1.2.10.4.5 (inclusive) of Volume IV, Surveillance and Collision Avoidance Systems, of ICAO Annex 10.

 (7) A rotorcraft must not fly in Australian territory if it is fitted with Mode S transponder equipment other than an approved ADS-B OUT equipment configuration, unless the equipment is:
 (a) deactivated; or
 (b) set to transmit only a value of zero for the NUCp, NACp, NIC or SIL.
Note: It is considered equivalent to deactivation if NUCp, NACp, NIC or SIL is set to continually transmit only a value of zero.

11.56  Alternate GNSS position source for ADS-B OUT — requirements
 (1) For a rotorcraft first certificated in its country of manufacture on, or after, 8 December 2016, an alternate GNSS position source is acceptable if the source:
 (a) is certified by CASA, or the NAA of a recognised country, for use in an IFR flight; and
 (b) has included in its specification and operation the following:
 (i) FDE, computed in accordance with the definition of the term at paragraph 1.7.3 of RTCA/DO-229D;
 (ii) the output function HPL, computed in accordance with the definition of the term at paragraph 1.7.2 of RTCA/DO-229D;
 (iii) functionality that, for the purpose of HPL computation, accounts for the absence of the SA of the GPS in accordance with paragraph 1.8.1.1 of RTCA/DO-229D.
 (2) For a rotorcraft first certificated in its country of manufacture before 8 December 2016, an alternate GNSS position source is acceptable if it meets the requirements of subsection (1), other than subparagraph (1)(b)(iii), which is optional.
