APANPIRG/23 Outcome on ADS-B (WP/03) 2.2 APANPIRG/23 meeting held in September 2012 reviewed the work accomplished by the Eleventh Meeting of the ADS-B Study and Implementation Task Force. The report of the Task Force had also been reviewed by CNS/MET SG/16 and the ATM/AIS/SAR SG/22 meetings. 2 Summary of Discussions 2.3 APANPIRG/23 appreciated the progress made by the ADS-B SITF and the SEA /BOB ADS-B WG and expressed its appreciation and gratitude to India for hosting the Seventh Meeting of the South East Asia and Bay of Bengal Sub-Regional ADS-B Implementation Working Group and to Republic of Korea for hosting the Eleventh Meeting of the ADS-B Study and Implementation Task Force. 2.4 The meeting noted the follow-up actions taken by the ICAO regional office and the guidance materials adopted by APANPIRG/23 which had been posted on the ICAO APAC website: http://www.icao.int/APAC/Pages/edocs.aspx 2.5 The meeting noted that APANPIRG Conclusion 23/33 regarding database of Blacklist Airframe broadcasting misleading ADS-B data was not supported by Australia. The reason was further explained in Working Paper 12 under Agenda Item 4. Review outcome of SEA/BOB ADS-B WG/8 Meeting (WP/07) 2.6 The SEA/BOB ADS-B Working Group meeting was held from 5 to 7 December in Yangon, Myanmar. The whole report of the Working Group is also available on the ICAO APAC website: http://www.bangkok.icao.int/cns/meeting.do?method=MeetingDetail&meeting_id=247 2.7 The meeting took following actions on the outcome of the SEA/BOB ADS-B Working Group: Need for ADS-B Station at Car Nicobar 2.8 While congratulating India on the smooth progress of deployment of 14 ADS-B installations, the Working Group meeting requested India to explore the possibility of an ADS-B installation at the military site at Car Nicobar, southeast of Port Blair to achieve better surveillance coverage of Bay of Bengal. It was recalled that discussions at previous ADS-B SITF/10 and Focus Group meetings had identified the need for an ADS-B station at the Nicobar Islands which would be beneficial towards enhancing flight safety, efficiency and airspace capacity over the eastern gateway of the Bay of Bengal Sub-region. The surveillance coverage would also be beneficial to States such as Malaysia and Indonesia. India agreed to explore the possibilities in this regard. In view of foregoing, the meeting endorsed following Decision formulated by the Working Group: Decision 12/1 – Need for an ADS-B Ground Station on the Nicobar Islands That, Task Force member from India is urged to explore the possibility of installation of an ADS-B Ground station at Nicobar Islands in order to enhance flight safety, efficiency and air space capacity over the eastern gateway of Bay of Bengal Sub-region. 2.9 The meeting noted the outcome of the discussion by the Working Group on potential ADS-B stations on the off-shore platforms. As an attractive option, many States would need guidance on how to engage with the platform operators. It was recommended that States should first initiate discussions with an offshore operating company to explore the possibility of ADS-B on offshore platforms. However, there would be difficulties for ANSPs in doing this work, as platform visits require significant specialized safety training. A possible deployment option would be to arrange an agreement with the platform operator to install and conduct Level 1 maintenance on the equipment, with the ANSP providing Level 2 and 3 maintenance support. Summary of Discussions 3 Co-ordination for Data Sharing 2.10 Discussion on ADS-B data sharing between States concerned including Myanmar and India was initiated at the eleventh meeting of APANPIRG ADS-B SITF in April 2012. The outcome of the initial discussion was further progressed at the ADS-B focus group meeting facilitated by CANSO on 3 and 4 July 2012 in Singapore. The discussion covered a draft ADS-B data sharing agreement, implementation issues, financing model, maintenance options and key project milestones between Airports Authority of India and DCA Myanmar. ADS-B Equipage Requirement and Required lead time for Mandate 2.11 The meeting was informed that by the end of 2013, DCA Myanmar will issue a mandate for ADS-B equipage of aircraft flying above FL260 on ATS routes M770 and L759 with target date 2015. 2.12 IATA commented that 50NM RHS was already applicable on routes M770 and L759, with reduction to 30NM separation it will also be achievable. Surveillance based separation standards could be applied after operational implementation of ADS-B. 2.13 With the installation of 14+7 ground stations and some upgrades to ATM automation systems, India was also expected to develop harmonized ADS-B equipage mandate requirement. 2.14 Regarding the lead time required for mandate, IATA clarified at the WG meeting that while in normal circumstances they would need 4 to 5 years to plan for mandated equipage, they would be prepared to work towards accommodating a 2 to 3 year period. IATA reminded the meeting that non-IATA members including domestic operators may require more time to get ready for the mandate requirement. Application of ADS-B based surveillance service 2.15 Singapore commented at WG meeting that there would be benefit in terms of priority of access to airspace on the basis of equipage i.e. best equipped, best served. IATA responded that the end benefit of radar or ADS-B surveillance is the implementation of surveillance separation standards. ADS-B Data Sharing between India and Myanmar 2.16 India is committed to seamless ATM and has committed its willingness for resource sharing at ICAO meetings. In the SITF/11 and BOBASIO/2 meetings as well as in APANPIRG/22 & 23 India has expressed willingness to share ADS-B data with Myanmar, Maldives, Sri Lanka, Malaysia and Indonesia. 2.17 India requested if other States having current cross-boundary data sharing agreements India could consider sharing these agreements, excluding any sensitive information, for use as guidance for other States contemplating such agreements. These could also then be used as a benchmark to better inform the regulator and thereby expedite the approval process. 2.18 In addition to in-principle agreement on sharing data with Myanmar, India and Sri Lanka may also share the ADS-B data from Trivandrum (India) and Pidurutalagala in Sri Lanka. The Chennai Upper Airspace Harmonisation has already led to significant improvement in operational efficiency and the sharing of ADS-B data with Sri Lanka will yield north bound flights from the island State significant benefits. Sharing of ADS-B data between India and Maldives - Hanimadhoo and Male ADS-B (Maldives) and Trivandrum/Cochin (India) would also result in significant improvement in service quality in Indian Ocean region. 4 Summary of Discussions 2.19 CANSO commended India for the leadership in ADS-B implementation in the Bay of Bengal area. CANSO proposed that if there were no bi-lateral or multilateral forums between India, Sri Lanka and Maldives then CANSO would be prepared to facilitate such a forum. 2.20 Australia commented that India’s proposals for data sharing, including VHF, were excellent steps. Australia also commented on the use of filters to provide independence of ASTERIX Cat 21 versions, security protection by acting as a proxy server, and a filter to facilitate the sharing of only that data which is agreed by the parties. The filter would also serve to limit the bandwidth used by not sharing the data which was not included in the agreement. 2.21 It is obvious that full benefits of ADS-B will only be achieved by its harmonized implementation and seamless operations. The meeting reviewed the agreement on the milestones for ADS-B data sharing between States in Bay of Bengal area and endorsed following draft Conclusion formulated by the WG: Draft Conclusion 12/2 - Milestone for Data-sharing between India and Myanmar That, the milestones for data-sharing as provided in Appendix A be adopted. 2.22 The working group meeting further deliberated and agreed on a framework regarding avionics standards, optimal flight levels, and ATC and engineering handling procedures on routes M770, N895, P646 and L507 in the Bay of Bengal area. The recommended Harmonization Framework for ADS-B Implementation along ATS Routes M770, N895, P646 and L507 in Bay of Bengal considered by the WG meeting is provided in Appendix B to this report. States concerned were requested to work closely together to achieve agreement as shown in the Harmonization Framework for implementation of ADS-B based service in the Bay of Bengal Sub-region Barometric and Geometric altitude Information in ADS-B message 2.23 Through a paper, Hong Kong China highlighted the technical difference between barometric altitude and geometric altitude, both of which are categorized as operationally desirable items in the APAC “Guidance Material on Generation, Processing and Sharing of ASTERIX Category 21 ADS-B Messages”. These two items are down linked along with other ADS-B data from aircraft to ATM automation system. It is essential to understand the technical differences and make proper use of the altitude information available from ADS-B messages in various ATC applications. The meeting discussed the safety implications in processing and displaying geometric altitude information to air traffic controllers by ATM automation system. The meeting concluded that the geometric altitude information shall not be provided to air traffic controller. It was considered important for Administrations to be fully aware of this safety issue about processing and displaying altitude information in ADS-B messages. The meeting also considered it necessary to amend relevant guidance in the ADS-B Implementation Guidance Document (AIGD) which was further discussed under Agenda Item 4. As result of further discussions during the Task Force meeting, a revised draft Conclusion was endorsed as follows: Summary of Discussions 5 Draft Conclusion 12/3 – Processing altitude information in ADS-B Message That, States/Administrations implementing ADS-B based surveillance services be urged to be fully aware of the safety implications and difference between geometric and barometric altitude. Geometric altitude information shall not be displayed on ATC displays used for provision of air traffic services. States may choose to use geometric altitude in ATM systems for other purposes. Proposal for Amendment to Supplementary Procedures 2.24 A Proposal for Amendment (PfA) to Regional Supplementary Procedures (SUPPs – ICAO Doc 7030) on the operation of ADS-B transmitting equipment was developed in accordance with APANPIRG Conclusion 22/36. As part of the established procedure, the proposal was circulated on 18 December 2012 after coordination with ICAO Headquarters. Up to Mid. February 2013, 14 responses were received. The meeting was informed that revised PfA with editorial changes was circulated again to the States on 16 April 2013 with closing date for receipt of the comments on 3 May 2013. European Aviation Safety Agency Notice of Proposed Amendment (NPA) 2012-19 2.25 The meeting noted that European Aviation Safety Agency (EASA) proposed through Notice of proposed amendment (NPA 2012-19) to remove requirement and provision of including part of AMC20-24. Regarding AMC 20-24, Certification Considerations for the Enhanced ATS in Non-Radar Areas using ADS-B Surveillance (ADS-B-NRA) Application via 1090 MHZ Extended Squitter has been recognized as one of regional equipage standards for implementation of ADS-B in the ASIA/PAC Region which has been included PfA to the SUPPs (Doc.7030). Chairman informed the meeting that he understood that EASA no longer proposes (or has postponed) to remove requirement including part of AMC20-24. 2.26 The Chairman noted the good work of the South-East Asia and Bay of Bengal Sub-regional ADS-B Implementation Working Group (SEA/BOB ADS-B WG/8). Agenda Item 3: Review outcome of AN Conf/12 on ADS-B related issues 3.1 Under this agenda item, the meeting reviewed a paper presented by the Secretariat on the outcome of AN Conf/12 on ADS-B related recommendations. A number of recommendations of the Conference were identified relevant to the work of the ADS-B SITF including but not limited to Recommendation 1/7, 1/9, 1/11, 2/2, 4/2, 4/3, 4/5, 6/5 and 6/6. The meeting was informed about the work being carried out by the ATM Seamless planning group on priorities of ASBU module as identified for the ASIA/PAC region including ADS-B ground surveillance service. 3.2 Considering several ADS-B related elements having been included in the ASBU document adopted by the AN Conf/12 in November 2012, Chairman proposed to further identify those regional ANS priorities that ADS-B can support for implementation. Participants from Australia, Singapore & Hong Kong China volunteered to prepare (coordination by email) a working paper with list of practical ADS-B related initiatives that could be considered by the ATM seamless planning group.
