Class B TABS position source device

      Mode S transponder — standard

      1 The Mode S transponder must be of a type that:
(a) is authorised in accordance with (E)TSO‑C166B, as in force from time to time; or
(b) approved in writing by CASA as meeting the specifications in RTCA/DO‑260B, whether dated 2 December 2009, or a later version as in force from time to time; or
(c) is authorised in writing by CASA as being equivalent to a device mentioned in paragraph (a) or (b).

      2 When required to be operated, the Mode S transponder must transmit NACp, NIC, SIL and SDA values in accordance with the authorised capability of the GNSS position source.

      GNSS position source equipment

      3 The geographical position transmitted by the Mode S transponder must be determined by:
(a) a Class B TABS position source device that is authorised in accordance with (E)TSO‑C199, as in force from time to time; or
(b) another source that is authorised in writing by CASA as being equivalent to a source mentioned in paragraph (a).

      Altitude source equipment — standard

      4 The pressure altitude transmitted by the Mode S transponder must be determined by:
(a) a barometric encoder of a type that is authorised in accordance with (E)TSO‑C88a, as in force from time to time; or
(b) another system that is authorised in writing by CASA as being equivalent to a barometric encoder mentioned in paragraph (a).
Appendix XIII — Approved equipment configuration — Integrated TABS device — VFR flight below FL290 only

Part A — ADS-B transmitting equipment — approval and application

      Approved equipment configuration — integrated TABS device

      1 Subject to this Part, an equipment configuration for ADS-B transmitting equipment is approved if it is an integrated TABS device that complies with the standards specified in Part B of this Appendix.

      Application

      2 An integrated TABS device carried on an aircraft has an approved equipment configuration if it complies with:
(a) the standards in Part B of this Appendix; and
(b) the conditions set out in clause 3.
Note   Another Appendix may apply to the equipment in a VFR flight.

      3 For paragraph 2 (b) an integrated TABS device may only be operated in transmitting mode:
(a) in VFR flight below FL290; and
(b) in Class D, Class E or Class G airspace.
Note   An integrated TABS device is not a substitute for mandatory carriage of a transponder in relevant airspace, except in Class E airspace, or in Class G airspace above 10 000 ft: see subparagraph 9E.2 (d); see also subparagraph 9BA.6 (b).

Part B — Standards for an integrated TABS device

      1 An integrated TABS device must meet the technical specifications in (E)TSO‑C199, as in force
