with the ICAO standards may provide misleading information to air traffic control. Operators need to ensure that EHS DAPs are being transmitted.
 (5) If an approved Mode S transponder is fitted to an aeroplane first certificated in its country of manufacture on or after 9 February 2012:
 (a) having a certificated maximum take-off weight 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 specified 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.
Note: Paragraph 3.1.2.10.4.2.1 is recommendatory only.
 (6) An aeroplane 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.
 (7) The pilot in command of an aeroplane for a flight must ensure the requirements in subsections (1) and (2) are met for the aeroplane and the flight.
Note: The aeroplane operator is also subject to the requirements in subsections (1) and (2), and each other requirement in this section and this Chapter that applies in relation to the aeroplane and a flight: see subsection 11.03(2).

11.69  Alternate GNSS position source for ADS-B OUT—requirements
 (1) For an aeroplane 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 national aviation authority of a recognised country for use in IFR flight; and
 (b) has included in its specification and operation the following:
 (i) FDE, computed in accordance with the definition at paragraph 1.7.3 of RTCA/DO-229D;
 (ii) the output function HPL, computed in accordance with the definition 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 an aeroplane 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.
Note: The following GNSS receivers meet the requirements of this section, namely, those certified to (E)TSO-C145a or (E)TSO-C146a, or later versions; or those manufactured to comply with (E)TSO-C196a. Some later versions of GNSS
