26.24 Mode S transponders, ADS-B OUT and electronic conspicuity equipment — specific requirements
       (1) An approved Mode S transponder fitted to, or carried on, a Part 131 aircraft for a flight must have the following details entered into the equipment:
(a) the assigned aircraft address;
(b) as far as practicable for the equipment — 1 of the following forms of aircraft flight identification:
           (i) if a flight plan is filed with ATS for the flight — the aircraft identification mentioned on the flight plan;
           (ii) if no flight plan is filed with ATS for the flight — the aircraft registration mark or other approved identifier, as applicable.
       (2) An approved ADS-B OUT equipment configuration, an approved integrated TABS device, or an approved EC device configuration, fitted to, or carried on, a Part 131 aircraft for a flight must have the following items entered into the equipment:
(a) the assigned aircraft address;
(b) 1 of the following forms of aircraft flight identification:
           (i) if a flight plan is filed with ATS for the flight — the aircraft identification mentioned on the flight plan;
           (ii) if no flight plan is filed with ATS for the flight — the aircraft registration mark or other approved identifier, as applicable.
       (3) An approved Mode S transponder must transmit each of the following when interrogated on the manoeuvring area of an aerodrome or in flight:
(a) the assigned aircraft address;
(b) the Mode A code;
(c) the Mode C code;
(d) subject to subsection (4) — the aircraft flight identification.
       (4) Transmission of the aircraft flight identification by an approved Mode S transponder is optional for an aircraft that was first issued with a certificate of airworthiness before 9 February 2012 (an older aircraft). However, an older aircraft that is equipped to do so may transmit its aircraft flight identification.
       (5) If an approved Mode S transponder transmits any Mode S EHS DAPs, the transmitted DAPs must comply with the standards set out in paragraph 3.1.2.10.5.2.3 and Table 3‑10 of Volume IV, Surveillance and Collision Avoidance Systems of ICAO Annex 10.
Note 1   Paragraph 3.1.2.10.5.2.3 includes paragraphs 3.1.2.10.5.2.3.1, 3.1.2.10.5.2.3.2 and 3.1.2.10.5.2.3.3.
Note 2   Australian Mode S SSR supports EHS DAPs. Transmission of Mode S EHS DAPs that are not in accordance with the ICAO standards may provide misleading information to ATS. Operators need to ensure that EHS DAPs are being transmitted.
       (6) Subject to subsection (7), an aircraft fitted with, or carrying, ADS-B OUT equipment that is not an approved ADS-B OUT equipment configuration, approved EC device, approved integrated TABS device, or approved Mode S transponder with Class B TABS position source device configuration, must not fly
