PARTAKE Report Summary

Project ID: 699307
Funded under: H2020-EU.

Periodic Reporting for period 3 - PARTAKE (cooPerative depArtuRes for a compeTitive ATM networK sErvice.)

Reporting period: 2017-03-01 to 2017-08-31

Summary of the context and overall objectives of the project

• What is the problem/issue being addressed?
PARTAKE focuses on improving the air traffic dynamic demand capacity balance by using means of the prompt identification of proximate events at network level, the re‐adjustment of take‐off times within the assigned nominal Calculated-Take-Off-Time (CTOT) margins and the rearrangement of departing sequence of aircraft at the involved airports to minimize the amount of ATC interventions. It can be considered as short term Air Traffic Flow and Capacity Management (ATFCM) measures applied at local level that reduces traffic peaks for the whole European airspace.

• Why is it important for society?
The motivation for the PARTAKE project is that European Air Traffic Management (ATM) system has to be competitive, supporting up to a certain extent the Airspace User (AU’s) demands at the right time (ie. departure slots), at the right cost (ie. suitable level of ATC service) at the right place (ie. AU’s preferred trajectories) and at the right service quality (ie. safety) without extra investments, just by removing the ATM non-added-value operations that somehow indirectly impact on present ATM capacity. PARTAKE is using the TBO approach preserving the 3D components of the Reference Business Trajectories (RBT’s) but adjusting the time component by means of micro-ground delays, providing a new smart mechanism to support conflict resolution (CR) collaborative-competitive tools with minimum ATC interventions.

• What are the overall objectives?
Objectives considering the ATM stakeholder interests are:
- Reduction of the probability of separation minima infringement: Preliminary results shows that implemented fine-tuning algorithms could be easily parameterized to provide robust clearances at hotspots for a certain rate of predicted conflicts. Thus, instead of minimizing the ATC interventions in a high sensible scenario that could generate cascade effects on downstream conflicts, PARTAKE tools could be used to provide a robust traffic in which a reduced amount of ATC interventions are considered as part of the solution.
- Enhancement of airport A-CDM processes: PARTAKE tools will contribute to a smooth integration of the different DST’s implemented at airport level in the ATM system, in which information about turnaround and taxi-out delays could be used for a better use of airspace resources.
- To improve ANSP predictive workload: The implemented TBO mapping tools provides a more accurate traffic information to Flight Management Position in which task load at sector level could be estimated at micro-level.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

The following tasks were performed from the beginning to the end of the third reporting period and the following main results were achieved:

WP3 the work performed during this reporting period focused on T3.4 and T3.5. An innovative trajectory interdependencies analysis based on graph theory was proposed (T3.5) and a method to assess the impact of uncertainties in the wind prediction on the accuracy of RBT management, focusing on the along-track errors was established.

WP4 - T4.1 This task describes the constraint programming model used for adjusting the take-off times and en- route speed of aircraft, as well as initial results obtained with this model when applied to a realistic scenario. T4.2: This task aims at reinforcing the solutions issued from PARTAKE mitigation tool towards small uncertainties. To this goal, the mitigation tool will be tested by either focusing on the densest areas, or by removing from the problem the most constrained aircraft, that will have to be handle by different procedures.

WP5 - T5.1: This task aims as assessing the cost incurred by PARTAKE tools on airspace users, and compare those costs to the current situation. This comparison relies on delay cost and fuel cost assessments based on literature and simulations with air traffic controllers. The deliverable is due end of October 2017.

WP6 – T6.1 PARTAKE Detection, Analysis, Mitigation and Information Management Tools will be verified in accordance with typical practice and the project requirements published in Deliverable D1.1.

WP7 addresses the communication, dissemination and exploitation issues of the project. T7.1 concerns the dissemination and communication strategy. T7.2 focused on the maintenance of the project website. T7.3 planning of dissemination events for awareness raising. T7.4 Exploitation Activities focus on defining a common path to exploits the most relevant outcomes beyond the project lifetime. The exploitation plan is based on analysis of the market and the project results.

WP8 The PM guaranteed an efficient and pro-active coordination of the project by administration, organization, and monitoring of the administrative and financial components of the project.

WP9 - Constant compliance with the 'ethics requirements' was ensured based on the guidelines developed in D9.1,9.2 and 9.3.

Summary of achieved main results:
- Implementation and release of the Detection, Analysis and Mitigation tool
- Development of an Analysis tool based on graph analysis and an uncertainty model
- Verification strategy defined and extension of PARTAKE application towards TMA environment
- Definition of the Exploitation Plan and strategy
- Maintenance of the Project Website (, involvement of the Advisory Board and establishment of a Newsletter
- Project Management guidance and ethics requirements assurance

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

It is expected that PARTAKE operational frame produces and supports the following impacts:
- TBO flexible synchronization mechanism to preserve ATFM constraints
- Reduction of the probability of separation minima infringement
- Competitive ATM Network Services
- Multi-Sector Planner mechanism
- Optimization model for a fine-tuning management of airspace resources
