  1. ASM Solutions at Network Level ASM / ATTFCM / ATS Workshop EUROCONTROL HQ 20-21 September 2012 Cristian Guran ATM expert EUROCONTROL DNM/COO/NOM/OPL/PROASM/ATM/ATFCM Procedures

  2. Aim and Objectives Aim: The ASM Solutions process is aimed to deliver ATFCM options to alleviate capacity problems identified in any particular area of European airspace in those cases when ASM is identified as one of the causes generating ATM delays. Objectives: • Address particular “hot-spots” to improve civil and military co-habitation; • Identify concrete and consistent solutions for each identified “hot-spot”, i.e. an interactive civil-military solution; • Develop local/regional ASM scenarios; • Improve CDR network, through harmonisation of CDR categorization across boundaries and develop proposals for simplification of current CDR categorisation if required EUROCONTROL ASM WS 20-21 September 2012

  3. Assessment Methodology Once a “hotspot” is identified: • Identify the traffic concerned (crossing an active MIL area or creating overload in a certain sector) • Seek avoiding solution for that traffic; • Optimization of the new trajectories using flight efficiency criteria; EUROCONTROL ASM WS 20-21 September 2012

  4. Example: Capacity shortage in LOVV sectors (1) First step: • Identify overloaded sectors: LOVVELUH, LOVVSUHT, LOVVWUH, LOVVNUH EUROCONTROL ASM WS 20-21 September 2012

  5. Example: Capacity shortage in LOVV sectors (2) Second step: • Identify traffic flows crossing the sectors concerned EUROCONTROL ASM WS 20-21 September 2012

  6. Example: Capacity shortage in LOVV sectors (3) Third step: • Solutions seeking The solution suggested by the findings: to take out traffic from LOVV sectors during the peak periods. But how? Which traffic? And when? • Network Rerouting Solution: Reroutes the traffic generating the overload in LOVV sectors to other sectors with spare capacity – e.g. LOVV to LIPP • Should be influenced by the activation of LI_R-49 • Network ASM Solution: Offers planning opportunities that can avoid LOVV sectors by insuring open CDRs in the peak periods EUROCONTROL ASM WS 20-21 September 2012

  7. 45 Airlines 61 Airlines Total cost of operations= Route extension (15 EUR/NM) + Route Charges Note 15 EUR/NM is the generic figure used by IATA to calculate total operational costs Example: Capacity shortage in LOVV sectors (4) Forth step: • Rerouting optimization Retain only solutions that have shorter distance and cheaper cost (route charges) EUROCONTROL ASM WS 20-21 September 2012

  8. Example: Capacity shortage in LOVV sectors (4) Network Rerouting Solution: traffic before and after rerouting from LOVV to LIPP sectors • Require availability of LI R-49 (partially) EUROCONTROL ASM WS 20-21 September 2012

  9. Before After Example: Capacity shortage in LOVV sectors (4) Synchronized non-activated areas: LF: CBA-1A,B, TSA-20A LS: TSA-400, 400P, TSA-501, 502 Network ASM Solution: CDRs required to be available during peak traffic Time period: 0900-1200 RED - Current FPLs BLUE - FPLs on available CDRs EUROCONTROL ASM WS 20-21 September 2012

  10. Example: Capacity shortage in LOVV sectors (5) Results (1): Compare the traffic load in LOVV to LIPP sectors: significant reduced in LOVV sectors with little effect in LIPP sectors EUROCONTROL ASM WS 20-21 September 2012

  11. Example: Capacity shortage in LOVV sectors (5) Results (2): The overload of LOVV sectors is dramatically reduced: EUROCONTROL ASM WS 20-21 September 2012

  12. Example: Capacity shortage in LOVV sectors (5) Effect of rerouting traffic on LOVV sector load: • 25 flights rerouted: • 3 overload peaks eliminated • Flights in excess in overloaded sectors reduced from 68 to 46 • 20 airlines concerned • 46 flights rerouted: • 4 overload peaks eliminated • Flight in excess in overloaded sectors reduced to 28 • 28 airlines concerned EUROCONTROL ASM WS 20-21 September 2012

  13. Rerouting Impact on ACCs – 25 flights Rerouting Impact on ACCs – 46 flights Example: Capacity shortage in LOVV sectors (5) Network impact: Effect of rerouted traffic on other ACC sectors EUROCONTROL ASM WS 20-21 September 2012

  14. Example: Capacity shortage in LOVV sectors (5) • Conclusion Solution 1 (Network RR): • Easy to implement; requires a mandatory rerouting scenario • Extra distance flown is the price paid for reducing the delays • Need to coordinate the R-49 availability • Conclusion Solution 2 (Network ASM): • Requires international and civil/military coordination to implement • Requires agreed procedures at network level to deploy the solution • Improve flight efficiency by distance savings • Resolve the capacity issue for a limited period • Other traffic can make use of the opportunities offered by available CDRs • Can have more potential if other CDRs are made available following the same approach • Solution 3 – a combination of the two above considering several options of military area selections that can accommodate RR traffic • Requires more in detail analysis of the impact for all actors involved • Could mitigate most of the drawbacks of Solution 1 and 2 EUROCONTROL ASM WS 20-21 September 2012

  15. Phased Approach for Network ASM Solutions EUROCONTROL ASM WS 20-21 September 2012

  16. General Conclusions for ASM Solutions Approach • The Optimized Total Cost solution maximize the benefit for the network producing a more off-load on sectors concerned • Impact on other ATC centres should be assessed for the actual conditions (sector configurations, opening schemes) • Any of the solution will require Aircraft Operators commitment • The increase in flight efficiency is higher for the Optimized Total Cost solution • The savings generated by the proposed solution will be also reflected by the subsequent reduction of the delay • Further investigation on impact to military operations is required • Network approach is paramount to find adequate solutions that have minimum impact on actors and deliver benefits EUROCONTROL ASM WS 20-21 September 2012

  17. Deployment and Promotion of Best Practices for ASM Solutions • ASM Solutions validation through trial at Network level or regional (FAB) • Quantitative analysis of trial results and lessons learned for subsequent implementation • Actors feedback paramount to further improve the process • Wide publicity of case studies for identified “hotspot” EUROCONTROL ASM WS 20-21 September 2012
