Aim and ObjectivesAim and Objectives

Aim: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: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


Assessment MethodologyAssessment 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;


Example: Capacity shortage in LOVV sectors (1)Example: Capacity shortage in LOVV sectors (1)

First step:First step: Identify overloaded sectors: LOVVELUH, LOVVSUHT,

LOVVWUH, LOVVNUH



Second step:Second step: Identify traffic flows crossing the sectors concerned



Third step: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



Forth step:Forth step: Rerouting optimization

Retain only solutions that have shorter distance and cheaper cost (route charges)

Total cost of operations=Route extension (15 EUR/NM) + Route

Charges

Note15 EUR/NM is the generic figure used by IATA to calculate total operational costs

45 Airlines

61 Airlines



Network Rerouting Solution: traffic before and after rerouting from LOVV to LIPP sectors

• Require availability of LI R-49 (partially)



Network ASM Solution: CDRs required to be available during peak traffic

Time period: 0900-1200

RED - Current FPLs

BLUE - FPLs on available CDRs

Before After

Synchronized non-activated areas: LF: CBA-1A,B, TSA-20A

LS: TSA-400, 400P, TSA-501, 502



Results (1):Results (1):

Compare the traffic load in LOVV to LIPP sectors: significant reduced in LOVV sectors with little effect in LIPP sectors



Results (2):Results (2):

The overload of LOVV sectors is dramatically reduced:

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



Network impactNetwork impact: Effect of rerouted traffic on other ACC sectors

Rerouting Impact on ACCs – 25 flights Rerouting Impact on ACCs – 46 flights



• Conclusion Solution 1 (Network RR):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):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 3Solution 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

General Conclusions General Conclusions for ASM Solutions Approachfor 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


Deployment and Promotion of Best Deployment and Promotion of Best Practices for ASM SolutionsPractices 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”
