UPDATE ON CASA RULEMAKING IN THE YEAR SINCE SITF/10 Regulatory Plan to support the future ATM system in Australia UPDATE ON CASA RULEMAKING IN THE YEAR SINCE SITF/10

DP1102AS – published September 2011 Revised Plan for Aircraft Communication, Navigation and Surveillance Equipage in this Decade

Technologies for the future Australian ATM - to year 2020 GNSS primary means navigation for PBN with a back-up network of ground based navigation aids About half the existing navaids to be retained Mainly VOR and NDB Mode S SSR in terminal areas, with ADS-B ADS-B & MULTILAT for A-SMGCS at 4 major aerodromes ADS-B surveillance in controlled airspace across the continent (plus Mode S SSR in high density en-route airspace on east coast)

Standards for Mode S transponders and changes to the ADS-B rule (NPRM1103AS) Contained the international equipment standards for Mode S transponders (including Downlink Aircraft Parameters - DAPs and antenna diversity in aircraft >5700kg/250kt normal cruise TAS) Also included conditions on flight with U/S ADS-B equipment and extended date for forward fitment of SA Aware in GNSS source for ADS-B - follow up to Conclusions taken at last SITF Meeting Singapore See WP/10 CASA website: http://www.casa.gov.au/scripts/nc.dll?WCMS:STANDARD::pc=PC_100688 NFRM 1103AS published on 25 Jan 2012 –http://www.casa.gov.au/scripts/nc.dll?WCMS:STANDARD::pc=PC_100828

Aircraft mandates necessary for the future Australian ATM GNSS primary means navigation – minimum equipage mandates required for PBN and ADS-B (CAO 20.18) PBN NAV specs (NPRM 1002AS) include RNP 10, 4, Basic RNP 1, RNP APP, RNP AR, Baro-VNAV Mode S transponders (with ADS-B capability) Further ADS-B mandates in controlled airspace TCAS II Version 7.1 – new turbine-powered aircraft i.a.w. the ICAO Annex 10 Volume IV standard

NPRM No 1105AS published January 2012 SATNAV minimum equipage requirement for PBN; Mode S transponders; ADS-B; forward fitment; TCAS II V7.1 Applicable Australian aircraft only- not foreign aircraft – although ADS-B requirements may be made applicable to foreign aircraft at later stage – see WP /11 for this Meeting CASA website: http://www.casa.gov.au/scripts/nc.dll?WCMS:STANDARD::pc=PC_100829

NPRM 1105AS SATNAV GNSS mandates (4) new RPT/Charter aircraft from 6 Feb 2014 existing RPT/Charter aircraft from 4 Feb 2016 new AWK/Private aircraft used in IFR flight from 6 Feb 2014 existing AWK/Private used in IFR flight from 4 Feb 2016 Mode S transponder (with ADS-B capability) mandates (2) All aircraft operating at Sydney, Melbourne, Brisbane, Perth from 4 Feb 2016 Forward fitment new aircraft operating Class A, B, C, E and >10000ft in G from 6 Feb 2014 ADS-B mandates (3) IFR flight - new aircraft - 06 Feb 2014 IFR flight – retrofit existing aircraft – by 02 Feb 2017 IFR flight within 500NM Perth - 04 Feb 2016 TCASII V7.1 mandate: forward fitment new aircraft from 1 Jan 2014 (ICAO date) Note : Existing aircraft = those on register before 06 Feb 2014; new aircraft = those registered on/after 06 Feb 2014

Proposed GNSS Navigation Equipment mandates ON/AFTER 6 February 2014 New RPT or CHTR aircraft (or retrofit GNSS installations in existing aircraft): 2 x TSO-C145 or -C146 or -C196 (or later versions) GNSS; or 1 x TSO-C145 or -C146 or -C196 GNSS + ADF or VOR; or GNSS system that has been approved by CASA as capable of achieving RNP in accordance with CAO 20.91. ON/AFTER 4 February 2016 Existing RPT or CHTR aircraft: 1 x TSO-C129 or -C145 or -C146 or –C196 GNSS + ADF or VOR; or GNSS that has been approved by CASA as capable of achieving RNP in accordance with CAO 20.91.

Cost of the mandates for the existing Australian fleet of IFR aircraft Approximately 4300 existing aircraft - cost estimated at $130M GNSS and ADS-B for installations not already completed Benefit estimated at $120M + mostly savings by reduction of ground navaids. Other benefits not costed - include fuel savings, environmental, safety, efficiency – very significant fuel savings estimates of PBN

Possible further aircraft mandates for ATM – under consideration ADS-B carriage all aircraft operating in Controlled Airspace (Class A, B, C, D, E airspace) - includes VFR aircraft – January 2020 (date to be confirmed) TCAS II V7.1 retrofit existing turbine powered aeroplanes > 5700kg/19PAX operating >FL285 - 1 Jan 2017; (partial compliance with the ICAO standard) NPRM on the above likely to be published before end-2012.

AC 21-45 – updated February 2012 Provides guidance and advice on the airworthiness approval for the installation of aircraft ADS-B equipment (GNSS+ADS-B transponder combinations) Link to CASA website: http://www.casa.gov.au/wcmswr/_assets/main/rules/1998casr/021/021c45.pdf

ADS-B requirement for surface vehicles at A-SMGCS aerodromes Sydney, Melbourne (PH and BN later) Vehicles operating on the manoeuvring area of major aerodromes having Advanced Surface Movement Guidance and Control System must be fitted with ADS-B transmitters (CASR Part 139 Regulation – see NFRM 0910AS April 2012) CASA website: http://www.casa.gov.au/scripts/nc.dll?WCMS:STANDARD::pc=PC_100879

A-SMGCS – Airservices system at 4 major international airports

Summary of Australian ADS-B mandates 12 December 2013 - Existing mandate for aircraft flight in airspace at and above FL290  - commences 12 December 2013 – applicable Australian and foreign aircraft. Note: Class A airspace in Australia generally extends upwards from FL245 ADS-B & RVSM airspace extends upwards from FL290 Future ADS-B mandates - currently applicable only to Australian aircraft - now being promulgated (NFRM 1105AS) Fitment to newly registered aircraft undertaking flight under the IFR – mandatory ADS-B from 6 February 2014 Retrofit of existing aircraft undertaking flight under the IFR - from 2 February 2017 aircraft must be ADS-B fitted             Western Australia airspace, all IFR aircraft operations - by 4 February 2016 Possible mandate - all aircraft operating in controlled airspace or above A100 in Class G – year 2020 (date to be confirmed) END   

Summary of basic benefits of the Australian future ATM system/avionics mandates Improved safety and ATM efficiency with Mode S and ADS-B surveillance Flight path optimisation with GNSS PBN (costs, fuel, emissions, noise) Increased air traffic density through accurate GNSS navigation and surveillance Reduction in CFIT and runway overrun through higher accuracy and integrity of GNSS PBN guidance Surface movement guidance and surveillance in low visibility (ADS-B surveillance) Minimised aircraft noise and optimised noise abatement flight paths (PBN based SIDs and STARs) with GNSS PBN Improved Search and Rescue detection and location (ADS-B surveillance)
