Orders/Civil Aviation as made
This instrument amends the Civil Aviation Order 20.18 (Aircraft equipment — basic operational requirements) Instrument 2014 to legislate appropriate equipment standards that will allow visual flight rules (VFR) aircraft voluntarily to use a broader range of air-to-air surveillance technology (in the form of Automatic Dependent Surveillance – Broadcast) than was previously available. The aim is to reduce the costs of installing air-to-air surveillance technology in VFR aircraft with a view to enhancing the basic VFR safety principle of “see and avoid”.

(a)   the equipment must comply with an approved equipment configuration under Appendix XI, XII, XIII or XIV in accordance with the Application provisions of the Appendix; and

(b)   for Appendix XIV, any administrative standard included in the Appendix must be complied with.

     9B.4     When serviceable ADS-B transmitting equipment is operated in Australian territory, the equipment must transmit:

(a)   the current aircraft address; and

(b)   a flight identification that:

             (i)  corresponds exactly to the aircraft identification mentioned on the flight notification filed with ATC for the flight; or

            (ii)  if a flight notification is not filed for the flight — is:

(A)    for an aircraft registered on the Australian Civil Aircraft Register and operating wholly within Australian territory — the aircraft’s registration mark; or

(B)    for an Australian aircraft registered by a RAAO — in accordance with the organisation’s operations manual; or

           (iii)  is directed or approved by ATC.

     9B.5     If an aircraft in flight carries serviceable ADS-B transmitting equipment, the equipment must be operated:

(a)   for equipment that complies with an approved equipment configuration set out in Appendix XI — continuously during the flight in all airspace and at all altitudes, unless the pilot is directed or approved otherwise by ATC; and

(b)   for equipment that complies with the approved equipment configuration set out in Appendix XII, XIII, or XIV — continuously during the flight, within the airspace and within the altitude limits specified for the flight in the applicable Appendix, unless the pilot is directed or approved otherwise by ATC.

     9B.6     Subject to paragraph 9B.7, 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, 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.

     9B.7     The ADS-B transmitting equipment need not be deactivated for paragraph 9B.6 if the aircraft is undertaking an ADS-B test flight in VMC in airspace below FL290.

     9B.8     An aircraft that is operated:

(a)   in an IFR operation; or

(a)   in any operation at or above FL290;

                 must carry serviceable ADS‑B transmitting equipment that complies with the approved equipment configuration set out in Appendix XI.

     9B.9     If an aircraft is operated in a VFR operation below FL290:

(b)   if it carries the equipment — the equipment must comply with the approved equipment configuration set out in Appendix XI, XII, XIII or XIV.

   9B.10     Paragraph 9B.8 does not apply to an aircraft if:

(a)   the aircraft owner, operator or pilot has written authorisation from CASA for the operation of the aircraft without the ADS‑B transmitting equipment; or

(b)   the equipment is unserviceable for a flight, and each of the following applies:

             (i)  the flight takes place within 3 days of the discovery of the unserviceability;

   9B.11     Unless otherwise approved in writing by CASA, ADS‑B transmitting equipment carried on an aircraft must allow the pilot to activate and deactivate transmission during flight.

Note   This requirement is met if the ADS-B transmitting equipment has a cockpit control that enables the pilot to turn ADS-B transmissions on and off.

   9B.12     A requirement under Appendix XI, XII, or XIII that an approved equipment configuration for ADS-B transmitting equipment be authorised in accordance with a specific TSO or ETSO does not apply to the ADS-B transmitting equipment carried on certain light sport, experimental and other aircraft provided that:

(a)   the equipment configuration that is carried provides the pilot, other aircraft and ATC with the same transponder and surveillance capability as would be provided if the equipment were expressly authorised in accordance with the specific TSO or ETSO; and

(b)   the pilot or the operator has a statement of conformance (however described) from the equipment manufacturer stating the particular standard or standards of the TSO or ETSO with which the equipment conforms.

   9C.11     For paragraphs 9C.3 and 9C.10, a requirement that the equipment be authorised in accordance with a specific TSO or ETSO does not apply to Mode S transponder equipment carried on certain light sport, experimental and other aircraft provided that:

(a)   the equipment configuration that is carried provides the pilot, other aircraft and ATC with the same transponder and surveillance capability as would be provided if the equipment were expressly authorised in accordance with the specific TSO or ETSO; and

(b)   the pilot or the operator has a statement of conformance (however described) from the equipment manufacturer stating the particular standard or standards of the TSO or ETSO with which the equipment conforms.

Note   The requirement is for aircraft to be fitted with a Mode S transponder with ADS-B OUT capability. That does not mean that ADS-B OUT transmission is also required under this paragraph. It means that, with the later connection of compatible GNSS position source equipment, ADS-B OUT can be transmitted as well as Mode S SSR responses.

(d)   for an aircraft that is operated under the VFR:

             (i)  in Class E airspace; or

            (ii)  above 10 000 feet AMSL in Class G airspace;
