He also thanked the ATMRI for their participation and valuable contributions towards the work of this review group. 3.2 The working language of the meeting and all documentation was English. A total of 08 Working Papers (WP) and 03 Information Papers (IP) were considered by the meeting. The list of papers deliberated is included as Attachment 2 to this report. 4. Meeting Report 4.1 Agenda Item 1:Adoption of agenda The provisional agenda, as listed in Attachment 3 was proposed for adoption by Hong Kong China and seconded by Singapore was unanimously adopted by the meeting. 4.2 Agenda Item 2: Review of the current and planned CNS/ATM capabilities and identifying associated reduced horizontal separation. WP06: Risk Assessment and Preparation for the Reduction of Longitudinal Transfer Separation in Sanya FIR 1

4 SCSTFRG/5 Report of the Meeting China presented a comprehensive review of the preparatory work being undertaken for the implementation of reduced longitudinal spacing on A1 and A202 with an emphasis on the importance of analyzing potential risks and mitigation. Sanya ACC is planning to carry out operational risk assessment using Early Waring Management System of Information Security and Operation Hazard Model, which is a risk analysis model used by the Middle South ATMB of CAAC Taking into consideration the increasing workload for ATC brought about by reduced longitudinal spacing, China expressed that the implementation of AIDC between Sanya ACC, Hong Kong ATCC, Ha Noi ACC and Ho Chi Minh ACC would be very beneficial for the reduction of longitudinal spacing on A1 and A202. They also emphasized on leveraging upon the existing overlapping surveillance coverage as well as limiting level changes at the transfer points. Transfer points should also not be treated as a limiting factor with states looking to earlier or later transfers to facilitate level changes to reduce risks from transferring during a transitory state Hong Kong informed that their new system was operational and the AIDC with Zhanjiang ACC will be tested and would continue the assessment before full implementation. Hong Kong also highlighted that if distance based separation standards were adopted, then time based revisions would be no longer applicable China pointed out that the number of flight conflicts near the transfer points were increasing. It was suggested that adjacent control units review and optimize the de-conflicting process to enhance flight safety. As presented in SCSTFRG/4, the operational difficulties on A1 was exacerbated in the airspace within the triangle formed by SAGSU-LENKO-BUNTA (A1/W171/G221) due to the rapidly increasing traffic into and out of Da Nang and Sanya airports. To mitigate conflicts in this airspace, China reemphasized the importance of establishing direct communications link between Sanya ACC and Da Nang APP. Vietnam replied that they were prepared to discuss this issue further as soon as possible China also suggested that traffic overflying Hong Kong FIR to Da Nang airport be transferred to Sanya ACC at FL340 or below China proposed a phased implementation of the 20NM reduced longitudinal spacing on A1/A202 as follows: Phase One, operational trial of reduced longitudinal spacing on A202 from 30NM to 20NM Phase Two, implementation of 20NM longitudinal spacing on A202. Phase Three, operational trial of reducing longitudinal spacing on A1 from 30NM to 20NM. Phase Four, implementation of 20NM longitudinal spacing on A IATA opined that anything that could be done to increase capacity was a move in the right direction. IATA highlighted that Singapore and Ho Chi Min had already implemented 20NM longitudinal spacing on M771/L642 within their FIRs. IATA urged the meeting to consider applying the same longitudinal spacing on these routes in the same timeframe proposed by China for the phased introduction of 20nm spacing on A1 and A202. 2

5 SCSTFRG/5 Report of the Meeting Hong Kong mentioned that reducing longitudinal spacing in M771/L642 had already been included in their assessment project. The impact of the reduced longitudinal spacing needed to be considered beyond Hong Kong FIR, into mainland China and Taipei FIR and beyond Vietnam informed the meeting that traffic transiting Vietnam airspace on A1 and A202 had increased rapidly. Currently, Vietnam applied 20NM longitudinal spacing on westbound traffic while 30NM for eastbound traffic and were ready to implement 20NM for eastbound traffic as soon as it was agreed to by the downstream FIRS Thailand suggested that a timeframe should be set on applying 20NM longitudinal spacing on A1 and A It was agreed in principle during SCS-TFRG/4 that the application of 20NM minimum surveillance based longitudinal spacing on ATS routes A1 and A202 could be considered 6 months after the transition of the new ATM system in Hong Kong, subject to a satisfactory completion of a safety assessment and operational review. Hong Kong informed the meeting that they will conduct the required safety assessment and would report the progress to the upcoming APAC ATM/SG meeting to be held in July Laos informed the meeting that they were already applying 20NM longitudinal spacing for westbound flights and were open to the application of 20NM longitudinal spacing for eastbound flights anytime the other states were ready. In response to China s query on the mitigation for loss of longitudinal spacing due to speed variation, Singapore shared with the meeting that their application of 20NM longitudinal spacing was subject to a no closing speed condition. WP07-Air Traffic Management Over High Seas Malaysia and Thailand presented the case for the responsibility to provide air traffic management services over international waters to be delegated on an interim basis to adjacent coastal states that offer better surveillance and communications capabilities. Taking advantage of these existing communication and surveillance capability would provide immediate benefits to the industry. Malaysia and Thailand further suggested the possibility to consider delegating the responsibility for provision of ATM services on specific airways within these areas to the better equipped states instead of waiting for technological advancements and the sharing of resources that was dependent on third party states The meeting was informed that the ICAO APAC Regional Office, in line with the ICAO Asia Pacific Seamless ATM Plan was already categorizing all airspace as either S or R based on the updated communication and surveillance coverage chart, including that over the South China Sea area. This chart depicts surveillance coverage and not location of the equipment. ICAO encouraged States to focus on reducing horizontal separation by taking advantage of the existing coverage The meeting agreed that the group should focus on enhancing the safety and efficiency of civil aviation based on the updated information in the ICAO Asia Pacific Seamless ATM Plan and where possible, encourage collaboration between States to share surveillance and communication capabilities. China informed the meeting that Sanya FIR was 3

6 SCSTFRG/5 Report of the Meeting fully covered by reliable communication and radar surveillance. Some adjacent airspace near boundary was also within the coverage. IP01 CNS/ATM of Indonesia The paper presented the current situation and CNS/ATM capabilities within Indonesia s 2 FIRs Indonesia informed that AIDC between Ujung Pandang ACC and Brisbane ACC had been implemented for northbound traffic and would be established for two way communications in the next 2 or 3 months. The AIDC between Ujung Pandang ACC and Kota Kinabalu ACC as well as the Ujung Pandang ACC and Manila ACC were expected to be established in the near future Indonesia also informed that 3 ADS-B ground stations at Tarakan, Manado and Galela had overlapping coverage that could be shared with Kota Kinabalu ACC and Manila ACC for surveillance along boundaries. IATA suggested the Philippines take advantage of the willingness of this ADS-B data sharing offer to improve their ATM operations near adjacent FIR boundaries. IP02 The Impact of Arbitrary Horizontal Spacing on Airways M771 on the tasks of FLAS/FLOS Review in South China Sea In presenting this working paper, Malaysia highlighted the fact that states affected by local conditions sometimes impose ad-hoc restrictions to manage air traffic flow. The notifications to relevant downstream ATC units and on to airlines were often issued late without adequate supporting information. This sometimes resulted in airborne aircraft having to turn around or boarded passengers waiting inside the aircraft for a long periods. Malaysia provided the meeting with their NOTAM records on the restrictions imposed on M Thailand informed the meeting that the Collaborative MIT Conversion Program (CMCP) project had been going on between China and Thailand, and that this initiative was currently applied on A1 and was regarded as helpful in increasing the predictability of ATFM measures. There are plans to extend this measure to M771 and other ATS routes as an interim solution to address concerns from affected states. Singapore also shared that such ad-hoc restrictions also affects their ability to merge air traffic from Kuala Lumpur, Jakarta and Singapore on M771. Singapore added that the conversion of Minutes in Trail (MIT) to calculated take off time would help to improve planning and predictability which is in line with the ongoing Distributed Multi-nodal ATFM project China opined that this ATFM issue could be further discussed during the ICAO ATFM SG Meeting which would be held the middle May in Fukuoka The meeting noted the heavy delay and short notification concerns raised by Malaysia and the negation of benefits of the reduced longitudinal separation and other capacity increasing measures achieved through committees like the SCS-TFRG. It was recommended that relevant ATFM steering/working groups review and discuss this concern further on an urgent basis. 4

7 SCSTFRG/5 Report of the Meeting IP03 THE PHILIPPINES CNS ATM CENTER Philippines presented an overview of their new CNS-ATM Center which would be officially handed over to CAAP in July of The new CNS-ATM Center represented a major improvement in communication and surveillance capabilities with an enhanced level of redundancy, which would be enable better accommodation of the ever increasing air traffic volumes within the Manila FIR with better efficiency and improved safety Philippines also informed the meeting that once the new CNS ATM Center becomes fully operational next year, they would start to reduce longitudinal separation for all en-route traffic from 80NM to 50NM. All ATS routes with the Manila FIR was expected to be converted to RNP10 at or above FL290 this year, and thereafter be upgraded to RNP4 for overflight traffic and RNP2 for domestic traffic in Q4 of The meeting was informed that some technical issues still occurred during the trial operations for ADS-C/CPDLC and needed to be addressed. The trial operation would continue till the end of this year. The meeting was also informed that ADS-C/CPDLC would only become fully operational once the Manila ACC had moved all its operations to the new CNS ATM Center Hong Kong China hoped to discuss with Philippines the implementation of AIDC and RNP10 routes to improve the operational efficiency. Hong Kong China also hoped that Sanya and Manila FIRs could share surveillance data to mitigate the gap in surveillance in the North West corner of Manila FIR Indonesia and IATA were also looking forward to the full operation of Philippines new CNS-ATM Center. It would be able to improve operational efficiency between Ujung Pandang FIR and Manila FIR and on other related ATS routes as well. 4.3 Agenda Item 3: Review of the existing MTF Route structure in SCS airspace and identifying priorities WP04 Updated WPACSCS 2016 Traffic Sample Data Visualization Thailand, through MAAR, compiled the Traffic Sample Data (TSD) submitted by states involved and presented an updated visualization of traffic flows in the South China Sea area based on 2016 TSD MAAR pointed out that there were some limitations on TSD data submitted: a) The chart did not include Sanya s traffic on A202 as no data was received. It was supposed to be obtained through China RMA. b) The TSD submitted by Hanoi did not allow clear visualization of Vietnam s domestic traffic as there were no designated entry and exit points identified in the data set. c) TSD from Vientiane was not received in time to be included in the visualization. 5

8 SCSTFRG/5 Report of the Meeting d) MAAR was agreeable to incorporating relevant data to be provided by Indonesia into the TSD Visualization and Indonesia did not have any objections for this data to be shared with ATMRI As the quality of TSD data was critical for the analysis and visual representation of traffic, the meeting urged States to provide data within the agreed time period and in the format requested by MAAR. MAAR informed the meeting that there were also able process raw FPL data sent by States. Whilst TSD in the agreed format was preferable, FPLs were also acceptable to MAAR for compiling traffic information required to produce the traffic density visualization. Singapore informed the meeting that for simulation purposes, high quality TSD was necessary for ATMRI to build simulation scenarios and conduct accurate analysis. WP08 Modelling Simulation of South China Sea Air Traffic This working paper, presented by Air Traffic Management Research Institute (ATMRI) provided the modelling and simulation of air traffic flows in the South China Sea (SCS) region using the System for Traffic Assignment and Analysis at a Macroscopic Level (SAAM) that enables analysis of current and future traffic flows to enhance safety, efficiency and capacity of airspace The modelling and simulation of the South China Sea (SCS) air traffic was conducted using MAAR s Traffic Sample Data (TSD) flow for the period from 1 to 7 December 2015 and was augmented with open source data The presentation covered Data Management of the TSD augmented with open source data to create a complete picture of the number of flights in the SCS region The 11 FIRs and all ATS routes within them were modelled for this analysis. From the data and simulation, the total number of flights in each FIR as well as the total number of flights in SCS region as a block were obtained and 4 December 2015, which had the highest traffic (6960 flights) was chosen for the analysis The meeting noted that analysis could capture the entry rate for a specific or combined FIRs and be calculated on an hourly basis. From the figures, it could identify the periods with the highest and lowest traffic movement for individual FIRs as well as the entire SCS. The top 30 ATS routes were identified and shown. The Route Optimization Study compared length, time, fuel, carbon dioxide and nitrous oxides emission of traffic between different scenarios, such as the Before and After scenarios of ATS Route changes A Complexity Study for the SCS area was presented and the meeting noted that there was no global complexity indicator that could be used as a threshold to indicate whether the degree of complexity is too high or too low for an ACC. Traffic conditions varied on different days and peak periods did not occur at the same time in all ACCs. For better analysis, the indicators would need to be computed on much wider traffic samples A simulation showing the traffic growth forecasts for ATS Routes L642 and M771 were also performed. The compound annual growth rate (CAGR) of L642 and M771 are 7.4% and 9.3% respectively. The analysis for the two options proposed by States for A1 was also presented to the meeting which included changes in complexity as well as comparisons of fuel consumption and emission 6

9 SCSTFRG/5 Report of the Meeting The meeting thanked ATMRI for its efforts and recognized that the study was valuable in assisting the group make informed decisions. The ATMRI indicated that they could assist SCS-TFRG with more in-depth studies with appropriate data provided by the States. The meeting noted the potential for ATMRI s collaboration with the SCSTFRG in airspace modelling and simulation as follows: a) identification of ATS routes with significant traffic flows within an FIR; b) identification of methods to alleviate choke and conflict points so as to enhance safety and capacity; c) optimization of airspace design; d) advanced complexity study. 4.4 Agenda Item 4: Discussion on PBN Routes Development and FLAS/FLOS Optimization WP01- Review FLAS Between Jakarta ACC, Ujung Pandang ACC, Kinabalu ACC and Manila ACC Indonesia presented the FLAS used between Jakarta ACC and Kota Kinabalu ACC, and Ujung Pandang ACC and Manila ACC. The meeting was informed that there were only 2 flight levels allocated on M772 which served the Jakarta-Hong Kong city pair. The current FLAS was inadequate due to the increasing traffic on this route. In this regard, Indonesia requested more flight levels for northbound traffic In presenting this working paper, Indonesia also pointed out that flights on routes G578, A461, R590, B472, B473 and B462 had increased significantly over the last 9 years. Due to the adherence to the FLAS, aircraft were forced to maintain uneconomical levels for long periods. Since the ATS system capability of Manila ACC would soon be similar to Ujung Pandang ACC, Indonesia proposed to discontinue the FLAS arrangement between Ujung Pandang and Manila ACC Philippines explained the difficulties faced with the current FLAS within Manila FIR due crossing and converging airways and suggested reducing longitudinal spacing on specific routes to accommodate the increasing traffic instead of changing existing FLAS between Ujung Pandang and Manila ACC. Indonesia agreed to further consider the proposal from Philippines as one of the options. WP02- FLAS/FLOS Chart Of The South China Sea Airspace This working paper captured, collated the data submitted by States in this area and provided a graphical representation of the FLAS/FLOS levels within the South China Sea Airspace. This was overlaid on the traffic visualization chart prepared by MAAR/Thailand. The chart, augmented with the traffic counts on the 30 busiest routes carried out by ATMRI was the used by the States in reviewing and analyzing current FLAS/FLOS The meeting took the form of a workshop to discuss the possibilities for the review of the existing FLAS/FLOS along some specific major routes. One group, involving the A1 7

10 SCSTFRG/5 Report of the Meeting states discussed the FLAS/FLOS arrangement on A1, A202 and on Vietnams domestic route W1 and W2 (Q1/Q2). The remaining states discussed the FLAS/FLOS arrangements on routes in the South Eastern part of the SCS. Hong Kong China and Philippines had a further side meeting to discuss routes between their FIRs The participants discussed the possibility of allocating more levels to Vietnam in view of the tremendous growth of traffic between the Hanoi-HCMC city pair. After considering the fact that these airways were within full surveillance coverage and had VHF DCPC, the states participating in the discussion, namely China, Hong Kong China, Laos, Thailand and Vietnam, suggested that there was no necessity to impose any FLAS/FLOS restrictions on Vietnams purely domestic airways W1/W2, on the condition that they allow all crossing flights on A1/A202 to maintain the designated FLAS/FLOS levels and Vietnam uses realtime surveillance based lateral separation for the domestic traffic Whilst Vietnam agreed that this was a good solution, they were unable to apply this methodology in the near term due to controller workload and safety issues due to the high density of traffic involved Thailand suggested that FL390, which was currently a FLAS level on A1 may be used by Vietnam s for its domestic traffic on W1/W2 after 20NM separation is implemented on A1. The states concerned agreed to this suggestion. Report from the side meeting between Hong Kong and Philippines Philippines informed that there is a plan to designate A461 and A583 as RNP10 routes after implementation of their new ATM system Philippines would study the proposal of releasing FL310 for southbound traffic landing Manila FIR via A461 and/or A583 on a conditional basis Hong Kong China would study the proposal of releasing FL320 for northbound traffic landing Hong Kong and/or Macao, Shenzhen and Guangzhou via A461 and/or A583 on a conditional basis. Report from the side meeting on FLAS/FLOS in the South Eastern part of the SCS Indonesia, Malaysia, Philippines and Singapore discussed the flight level allocation on ATS route M772. It was noted that the existing FLAS of FL300 and FL380 on M772 is based on the no pre-departure coordination (No PDC) arrangement. Indonesia said that flights from Jakarta would have flown more than 2 hours after departure and being allocated FL300 throughout was not economical. Indonesia also requested for other levels to be assigned to traffic on M Philippines reported that other flight levels are not available as they are being utilized by flights on other routes such as L625 (FL310, FL320, FL350, FL360), L628 (FL330, FL370 westbound, FL280, FL340 eastbound). Indonesia inquired about the feasibility of assigning FL340 on a tactical basis depending on the traffic conditions on L628. 8

11 SCSTFRG/5 Report of the Meeting Philippines replied that the volume of traffic on L628 was relatively higher than M772 as it was the main route serving flights from Manila to Bangkok, South Asia and the Middle East. As such, FL340 would normally not be available. However, it was possible to consider real-time coordination between Singapore and Manila ACC. Singapore said that they would facilitate as long as approval can be obtained from Manila ACC Philippines agreed that availability of FL340, or any other levels would be subject to coordination depending on the prevailing traffic. However, Philippines added that due to the absence of surveillance and the low level of communication coverage with HF, ATC tactical intervention on the M772 would be challenging for level changes to be effected within Manila FIR. However, Philippines hoped that with the upcoming commissioning of their new CNS/ATM capabilities by end of 2017, the situation would improve Apart from availability of FL340, Indonesia suggested the reduction of longitudinal separation as an alternative to optimize capacity on M772 and in the interim, to also consider non-standard level allocation, subject to prior coordination and agreement. The Philippines stated that with the planned commissioning of their new CNS/ATM there would be improved surveillance and communication capabilities (ADS-C and CPDLC) along M772. This capability would be used to reduce the required longitudinal separation to 50NM thus increasing the capacity of M772 to accommodate more flights, subject to the impact on downstream FIRs The side-discussion concluded that FL340 on M772 would be available subject to coordination. Furthermore, with the planned commissioning of new surveillance and communication capabilities (ADS-C and CDPLC) along with resectorization by December 2017, the situation of level allocation would improve on M772. Report from the side meeting between Indonesia and Philippines Indonesia and Philippines discussed the flight level allocation on ATS route A461, G578, B473, B472 R590, R340 and B462. It was noted that the existing FLAS of FL300, FL340 and FL380 on routes mentioned was based on the no pre-departure coordination (No PDC) arrangement. Indonesia said that flights from Ujung Pandang was increasing as the returning flight coming from Australia. With the available communication and surveillance capabilities within the Ujung Pandang FIR, Indonesia requested for other levels to be assigned to those routes and requested whether Philippines would be able to climb and descend after the traffic had entered their the FIR boundary because the adequate distance before the crossing point Philippines informed that other flight levels were not available as they were being utilized by flights coming from Oakland, Japan and Taipei as well as their northbound domestic traffic flow. Due to the lack of communications capability and the absence of surveillance around the area (Zamboanga, Cotabato, Tambler and Davao) at the present time the Philippines was unable to make the flight level transition within the Manila FIR after the common FIR boundary with Indonesia. The Philippines informed that after the commissioning of the new ATC System they will evaluate and facilitate the update coordination procedure, Flight Level Allocation Scheme and longitudinal spacing. 9

12 SCSTFRG/5 Report of the Meeting The side-meeting concluded that Indonesia and the Philippine would maintain FLAS and the longitudinal separation as per LOA and with the planned commissioning of new ATC System (surveillance and communication capabilities) by Q1 2018, the situation of level allocation and longitudinal separation would be improve on routes between Indonesia and Philippines. Report from the side meeting between Malaysia and Singapore Malaysia proposed for FL370 to be assigned as FLAS for ATS route M758 and M761. Based on day-to-day operations, flights operating on these routes were being approved to operate at FL370 and it would be very economical for operators to flight plan at this flight level Malaysia also proposed for FL370 to be assigned as the No-PDC for ATS route M758 and M761. Proposed new No-PDC arrangement: FL290/330/370. Current No-PDC arrangement: FL270/290/ Singapore will review these proposals and to provide update. Report from the side meeting on A The side meeting was attended by China, Hong Kong, Laos, Vietnam and Thailand The review of the proposals 1 and 2 on traffic orientation for A1 parallel route was discussed. Thailand, in view of their already established parallel route system within their FIR required the orientation depicted in Proposal 1. Proposals 1 or 2 were acceptable to China. Hong Kong China Laos and Vietnam expressed their preference for proposal 2. Vietnam preferred proposal 2 in order to facilitate arrivals and departures from Da Nang Airport. Hong Kong would conduct further studies on Proposal 2 and report progress to next meeting. The RSO would liaise with CAAS/ATMRI and states involved if there was a need to conduct further analysis A preliminary consensus was reached to consider the application of RNAV2 Specs for this parallel airways in view of the good surveillance coverage and VHF DCPC. IATA supported the selection of this NavSpecs In view of this impasse, states are encouraged to continue their discussions bilaterally or multilaterally and determine a solution to the orientation of the traffic flow. WP03-Proposal for the Establishment of New Routes within South China Sea Malaysia presented proposals for the establishment of new ATS routes within South China Sea between city pairs: Kota Kinabalu (WBKK/BKI)-Hong Kong (VHHH/HKG); Kota Bharu (WMKC/KBR)-Kota Kinabalu (WBKK/BKI) and Kota Bharu (WMKC/KBR)- 10

13 SCSTFRG/5 Report of the Meeting Kuching (WBGG/KCH) and requested to incorporate these requirements in the APAC ATS Route Catalogue Singapore expressed that as these proposals involved, the establishment of routes through Singapore FIR and that they would review the feasibility of these new routes Indonesia reminded the meeting that as proposals 2 and 3 routes would traverse Indonesian sovereign airspace, Indonesia requested Malaysia and Singapore to discuss with Indonesia for any changes to routes over Indonesian sovereign airspace before the establishment of any new routes involving this airspace The meeting would make recommendations to SEACG to incorporate these requirements into the APAC ATS Route Catalogue. WP05- Analysis and Suggestions To Promote Expeditious Traffic Flow On Route A China conducted a comprehensive analysis on the traffic on ATS route A1 and proposed a two-phase scheme to improve the operational efficiency of A1, including reducing the longitudinal spacing to 20NM, increasing available flight levels on A1, enhancing CNS/ATM capability and establishing a new route parallel to A Hong Kong China expressed that due the complex situation in Hong Kong FIR including the convergence of high density routes and the flight level transition from feet to meter into mainland China, they need a safety analysis on the impact of reducing longitudinal spacing and new route proposals. ICAO suggested China to consider applying imperial flight level system so that the additional ATC workload of transition between different systems could be mitigated. Thailand suggested that the setting of timelines for these activities would make progress more trackable. 4.5 Agenda Item 5: Review and update of the task list of SCSTFRG The task list for the SCS-TFRG was discussed and adopted by the meeting, and is appended to this report as Attachment Agenda Item 6: Decisions/Recommendations to SEACG Recommendation 1: Review and incorporate the new ATS route requirements proposed by Malaysia into APAC Route Catalogue Recommendation 2: Review the FLAS interface between the SCS and its neighboring airspace, identify the potential problems. 11

14 4.7 Agenda Item 7: Any Other Business SCSTFRG/5 Report of the Meeting There were no issues raised under this agenda item. 5. Closing of the Meeting The Chairman thanked Singapore for hosting this meeting. He also thanked ATMRI and MAAR for their support and congratulated all participants for the successful completion of the meeting The Secretariat suggested that the next meeting be held in approximately 6 months. The Secretariat will announce details in due course. 12
