#IFLEX/3 Draft Report-Approved at meeting



THIRD FLEXIBLE ATS ROUTE MANAGEMENT WORKSHOPDraft REPORTParis, France, 8 to 10 March, 2011PART I – HISTORY OF THE WORKSHOP1. PLACE AND DURATION1.1 The Third Flexible ATS Route Management Workshop convened at the initiative of IATA and with the support of ICAO and CANSO was held in at the ICAO EUR/NAT Offices in Paris from 8 to 10 March 2011. 2. OPENING, OFFICERS AND SECRETARIAT2.1 The workshop was opened with welcoming remarks by Mr. Sven Halle, Regional Officer, ANS Implementation, ICAO EUR/NAT Office.2.2. The proceedings of the workshop were conducted by Mr. Don Harris from IATA Montreal. Ms. Carole Stewart-Green ICAO EUR/NAT and Ms. Patricia Cuff, ICAO EUR/NAT supported him as members of the secretariat for this workshop. 3. ATTENDANCE3.1 The workshop was attended by a total of forty-two (42) participants from thirteen (13) States, namely Angola, Argentina, Cape Vert, Colombia, France, Israel, Italy, Namibia, Nigeria, Portugal, Republic democratic de Congo, Senegal and Turkey and eight (8) organizations and corporations (ASECNA, CANSO, Delta Air Lines, Emirates, IATA, ICAO and Jeppesen, The list of participants is at Appendix B to this report.4. LANGUAGE4.1 Discussions were conducted in the English language.5. I-FLEX BACKGROUND, CONCEPTS AND SOLUTIONS; AGENDA OF THE WORKSHOP5.1 In the Global Air Navigation Plan (Doc.9750), ICAO introduced the concept of dynamic and flexible ATM as one of its Strategic Objective. Global Plan Initiative (GPI-7) states that routes need not be fixed to pre-determined waypoints, except where required for control purposes. GPI-8 enhances the implementation process with Collaborative Decision-Management techniques to organize airspace in a collaborative manner involving all stakeholders to accommodate user-defined flexible routings.5.2 iFlex intends to build on these Strategic Objectives and transition into a more dynamic environment that remains agile enough to address daily flight operations variables, yet remains responsive to Air Traffic Management (ATM) and Operators’ needs. Flexibility is derived from the design of the airspace and opportunities exist in almost all operating environments, whether dense and short-haul or sparse traffic flows and long-haul flights.5.3 Specifically, environmental benefits in fuel burn and CO2 avoidance are significant in longer-range flights. This is evident in the two sampled long-haul flight routings – that of Emirates Airlines flying from Dubai to Sao Paolo and Delta Airlines on the Atlanta to Johannesburg leg. Flying across the South Atlantic airspace, and the recent activation of the AORRA (a random route area), there remain a limited number of access points available for entering and exiting this airspace, especially on the northwestern and western boundaries (Dakar, Atlantico, Rochambeau and Piarco FIR’s). The relative lack of a supporting infrastructure (lack of transition waypoints/routings) substantially limits the ability to accomplish route efficiencies sought after by the ICAO Global roadmap. Besides finding ways and means to identify the major challenges on long-haul operations, a collaborative process involving all stakeholders in the context of an end-to-end flight routing was necessitated by means of a workshop setting. 5.4 iFlex Solution: In order to realize the fuel savings and Carbon Emission reductions envisioned by the creation of the AORRA, both additional AORRA entry waypoints, transitions to domestic/continental airspace and additional crossing opportunities for the EUROSAM corridor are required. The two ‘demo’ flights deployed as proving flights for the iFLEX concept are estimated to yield approximately 2,3 million kgs CO2. In view of the above, the agenda at Appendix A to this report was established for the workshop.PART II-SUMMARY OF DISCUSSIONSII-1 March 8, 2011 Workshop Agenda:IATA presented an introduction to the iFLEX program, its concepts and objectives. The presentation demonstrated the fact that the preferred daily trajectory on a given city pair could vary greatly on a seasonal and even daily basis.Received briefing from Emirates on Dubai (DXB) to Sao Paulo (GRU) user preferred routes to achieve maximum efficiencies and carbon emissions savings based on prevailing wind models. Emirates highlighted best practices and benefits from the Free Route Airspace Lisbon initiative and the North American Route Plan. Emirates briefed the Group on the new temporary airways that span the northern part of the African Continent that were agreed at Workshop 2Received briefing from Delta on Atlanta (ATL) to Johannesburg (JNB) user preferred routes to achieve maximum efficiencies and carbon emissions savings based on prevailing wind models. Delta provided a briefing on changes to airspace infrastructure that were agreed at Workshop 1 and the positive affect these changes are having on Delta’s operations.ZzzzThe Group reviewed the results of Workshop 1 and updated the Future Actions and Proposals from the Meeting Report. It was noted that the future actions had either been completed or were addressed in this report.Senegal ASECNA informed the Group that an issue had arisen during their safety case. It was noted that lateral deviation due to weather conditions occurred frequently particularly during the rainy season. the quality of HF radio was sometimes degraded during the rainy season. Mitigations would be put in place and this issue will not affect the actual conduct of the trial.During the course of Workshop 1 it was agreed that:Individual FIR’s would publish named waypoints for implementation date allowing for 3 AIRAC cycles starting March 10, 2011 and for an effective date of June 2, 2011 andA trial period would allow Delta Airlines and Emirates Airline to commence participating with trial flights from April 7, 2011 through June 2, 2011. The trial will be conducted on the basis of a Letter of Agreement between individual ANSP’s and the two participating airlines respectively.To provide clarity to the decisions taken at the first Workshop it was agreed that the named waypoints would be published on the March 10, 2011 AIRAC date with an effective date of the airspace changes on April 7, 2011. A trial utilizing AORRA entry / exit points and EUR SAM corridor crossing points would then be conducted; exclusively byto Emirates and Delta Air Lines between April 7 and June 29.The period of the trial was extended until June 29 to line up with the timing of the trial of continental African routings that were agreed at Workshop 2.Pending Following the a successful result from the trial, Flex route operations utilising AORRA entry/exit points and EUR/SAM corridor crossing points would then be available for all operators on June 30, 2011.After reviewing the decision to conduct the trial on the basis of a Letter of Agreement between individual ANSP’s and the two participating airlines it was agreed to drop this requirement as no value was seen in doing so and it appeared to be an overly cumbersome process.It was noted that co-ordination with Sao Tome was not completed in time to meet the March 10, 2011 AIRAC date this resulted in two routes between Sao Ttome and Libreville being dropped from the list of proposed airspace changes agreed at Workshop 1. Efforts will be made to complete the necessary co-ordination in time to meet the April 7, 2011 AIRAC date.Efforts continue to convene a joint meeting with Atlantico, Piarco, Cayenne-Rochambeau, and Dakar and United States to reach further agreements to complete and harmonize implementation of iFlex infrastructure improvements allowing for more efficient routes and environmental savings in the South Atlantic airspace. A meeting in April appears to be feasible and efforts will continue to convene the meeting.ffffThe Group reviewed the results of Workshop 2 and updated the Future Actions and Proposals from the Meeting Report. It was noted that the future actions had either been completed or were addressed in this report.It was noted that IATA and ICAO had not been able to complete coordination of proposed airspace changes with Entebbe, Nairobi, Adddis, Asmara, Cairo, Tripoli, Amman and Sana’a FIR’s. This was due in part to the current political climate in some of these areas. Mr. Konate and Ms. Sayed will continue efforts to coordinate airspace changes requirements with above FIRs.During the course of Workshop 2 it was agreed that:Continental routings would be published under AIRAC April 7, 2011 AIRAC Cycle with effective date 30 June 2011. Those ANSPs who are unable to access web based ICARD system, 5NLC’s will be obtained from ICAO.To provide clarity to the decisions taken at Workshop 2 it was decided that the continental routings which would be designated as “UQ” would be published under AIRAC April 7, 2011 with an effective date of May 5, 2011. They would be designated as RNAV10 routes.A trial utilizing the continental routings would then be conducted; exclusive to Emirates and Delta Air Lines between May 5 and June 29.Pending aFollowing the successful result from the trial, the UQ airways continental routings would then be available for all operators. on June 30, 2011.Received Briefing from IATA introducing Civil – Military cooperation. The briefing presented a number of options to consider when conducting co-ordination between civil and military authorities. Received Briefing from IATA introducing Civil – Military cooperation. The briefing presented a number of options to consider when conducting co-ordination between civil and military authorities. It was noted with regret that the military authorities invited to the meeting had not been able to attend. Flexible Use of Airspace and Civil – Military cooperation in the UAE, Bahrain, Qatar and Saudi Arabia are key enablers for the success of the demonstration flights. Several route proposals, as found in Appendix B, are contingent upon approval by military authorities in the afore-mentioned States. Some work in this area may be advanced at the MID Region Civil-Military Conference in Cairo in May. Participants in Workshop 3 with experience in effective Civil – Military cooperation provided examples and suggestions that could serve to assist those States that do not yet have Flexible Use of Airspace. Appendix C of this report contains guidance to AOs, ANSPs/CAAs and Military Authorities to facilitate the use of User Preferred Trajectories in the context of the demonstration flights.It was noted with regret that the military authorities invited to the meeting had not been able to attend. Some work in this area may be advanced at the MID Region Civil-Military Conference in Cairo in MayII-2 March 9, 2011 Workshop Agenda:NAV Portugal gave a detailed briefing on Flex Route operations in the Lisbon and Santa Maria FIRs. It was noted that significant savings in miles flown and associated reductions in greenhouse gas emissions had been achieved as a result of the Free Route Airspace Lisbon (FRAL) initiative. NAV Portugal advised that FRAL had been implemented with little operational difficulty and that the Lisbon airspace was being now managed more efficientlyThe Group the reviewed a proposed Draft AIP Supplement that each State could use to promulgate the airspace changes that will be announced via the March 10, 2011 AIRAC date. It was noted that having each State use a consistent format and the same wording would be a benefit. A copy of the agreed AIP Supplement is attached at Appendix CD.It was agreed that States would use different methods to announce the commencement of the trial. Some States advised that they would issue a NOTAM to announce the commencement of the trial while others would include information regarding the trial in their AIP supplement.A draft AIC, providing information on the iFLEX Project and the conduct of the two trials was presented to the Group by CANSO. It was greed that it would be beneficial if all States issued this AIC to provide awareness to the aviation community of both the iFLEX Project and the associated trials. Some editing of the AIC required prior to issue. A copy of the Draft AIC is attached at Appendix DE.Delta Airlines gave a presentation of TAAM simulation of 24 hour traffic periods for the Europe to South America corridor as well as Continental Africa. The simulation was prepared using the information contained in the Official Airline Guide. It was noted that this presentation was helpful in presenting the general volume and flow of traffic in these two areas. However, it would be beneficial to have live traffic data available to make a more robust simulation of traffic over the Continental Africa. CANSO offered to gather the data and begin the task of developing simulation. With that in mind, each State and ANSP is encouraged to provide a month of AFTN data to Mr. Greg McDonald of Air services Australia to enable this process to begin.The Group discussed ways and means of measuring the success of the trials. Delta and Emirates agreed to compile a file showing the savings in fuel burn and emissions savings accumulated over the period of the trial. For each participating flight a flight plan will be generated using the fixed route structure as it is today. The airlines will then generate a Flex Route, which will be the route filed and flown. A calculation of the resultant savings will then be calculated and recorded. The airlines will also monitor their actual flight trajectories flown and compare them to the planned trajectory by means of post-flight crew debriefs.States, and ANSPs and airlines that that encounter operational problems during the conduct of the trial will submit a problem report for review and corrective action. IATA agreed to act as the monitoring agency for the conduct of the trials. All problem reports should be submitted electronically to iflex@.IATA then briefed the Group on the next steps for the iFLEX program. Lessons learned will be gathered from the trials that will be conducted between April and June 2011. The results will be incorporated into the iFLEX Guidance Material. Based on the results IATA intends to conduct future trials using the same conceptual framework as used in the initial iFLEX trials.It was noted that the SESAR JU has expressed an interested in implementing Flex Routes on the EUR/SAM corridor.No items were brought forward during the Any Other Business discussions.II-3 February 17, 2011 Workshop Agenda:The Group met in plenary to review the work of the breakout groups and to begin drafteding the meeting report.Appendix AProvisional AgendaAgenda Item 1: Welcome, Introductions and LogisticsAgenda Item 2: Briefing on the aims of the iFLEX program.IATA will brief the Workshop on the origin, aims and objectives of the iFLEX Program.Agenda Item 3:Best practices briefings and demonstrations.CANSO will brief the Workshop on Flexible Route initiatives that have been implemented in other Regions and States.
