Periodic Reporting for period 5 - COCTA (Coordinated capacity ordering and trajectory pricing for better-performing ATM)
Okres sprawozdawczy: 2018-04-15 do 2018-09-14
If ATM capacity exceeds demand, costs for providing ATM services and consequently ATM charges are above the inevitable level. In case of capacity shortages, airlines and other aircraft operators are forced to deviate from their optimum flight plans, leading especially to delays and additional fuel burn. The COCTA project aims at increasing efficiency by better matching ATM capacity and demand.
The COCTA team proposed a redesigned ATM value-chain, also introducing a new process of capacity and demand management. The Network Manager orders capacities from Air Navigation Service Providers at several instances, i.e. at long-term, medium and short term to adjust orders to meet air traffic demand in the cost-efficient manner. On the other side, the Network Manager defines different trajectory products to meet Airspace Users' needs, but also to improve overall network performance.
We used real data to evaluate the model and to evaluate our ability to solve the model using a large-scale case study. Wetested the improved COCTA model using more than 11,000 flights flying over central and western Europe.
We presented a paper, using a large-scale case study, to stakeholders at the Research Workshop on Volatility in Air Traffic and its impact on ATM Performance, jointly organized by FABEC, Baltic FAB, G.A.R.S. and Warsaw School of Economics (Warsaw, Poland, 15-16 May 2018). Also, we presented the project results to Director of the Network Management Directorate, and other representatives from the Network Manager Directorate, Brussels, Belgium, 14 May 2018. Finally, the COCTA team presented the final concept and results from the large-scale case study to Swiss Air Navigation Service Provider - Skyguide - representatives in Geneva, Switzerland, 23 July 2018.
The COCTA concept aims at improving efficiency of the ATM system which directly benefits the air transport industry as well as its users. However, since COCTA is a TRL1 project, i.e. fundamental scientific research, it is not ready for implementation, but needs further conceptual as well as applied research. Nevertheless, using the large-scale case study for model testing and evaluation, we showed the potential benefits that might be achieved by implementing COCTA concept in practice.
