Periodic Reporting for period 1 - PJ09-W2 DNMS (Digital Network Management Services)

Reporting period: 2019-12-01 to 2020-12-31

"The SESAR project ""Digital Network Management Services"" or DNMS is focusing on improvement of the network traffic prediction and shared complexity representation for all Demand Capacity Balancing actors, Dynamic Airspace Configurations (DAC), integrated network management and ATC planning (INAP) and collaborative network performance management.
Today's airspace sector design and configuration is not integrated with the demand and capacity balancing process resulting in inefficiencies of the network. The current quality of NM demand predictions does not allow optimal use of complex Dynamic Airspace Configuration algorithms nor does it allow adequate planning of Flight Plans in the tactical and pre-tactical phase. Traffic complexity definition is managed at local level, hampering a network wide awareness of traffic situation and collaborative decision making. Today's monitoring of the network does not allow to detect emerging disruptions requiring network DCB solutions, often resulting in a multitude of local DCB measures.

Addressing of these problems is important to achieve a more optimal use of the Air Traffic Management Network which will reduce delays and overall costs with less environmental impact thanks to better optimisation of flight plans.

These problems will be addressed in 3 different solutions with following key-objectives:

• Solution 44: Dynamic Airspace Configurations (DAC)
Main objectives are to: address the application of advanced types of airspace use coordination processes, validate user acceptability and the feasibility of the DAC processes, validate automation in support of military airspace users and the use of the Dynamic Mobile Area concept, develop a What-If tool for Airspace Management process, automate the integration of DAC in the INAP processes.
• Solution 45: Enhanced Network Traffic Prediction and shared complexity representation
Main objectives are to: improve tthe IATA/ICAO Flight ID mapping in the pre-tactical time horizon, improve the pre-tactical ANSP scenarios and therefore the Initial Network Plan (INP) based on the improved predicted demand, update and validate the use of probabilistic occupancy counts algorithm developed in Wave 1 as a complement to the entry and occupancy counts in the Tactical time horizon.
• Solution 49: Collaborative Network Performance Management
Main objectives are to: develop and validate an operational states prediction algorithm used to anticipate the emergence of performance degradation in identified areas within the network, validate the transition from local to regional measures in critical operation conditions, with a focus on the impact on current local and network procedures as well as design and coordination of network recovery plans based on network state predictions to improve the network recovery and faster return to nominal operations, validate that the integration of the airport and network performance dashboards will assist the design of collaborative recovery procedures and participate to the pro-active management of predicted performance deterioration."
Solution 44

• Development of an initial operational concept document (OSED)
• An initial version of the validation plan (VALP) was developed

Solution 45

• Advanced initial and final OSED, accepted by SJU
• Advanced initial and final VALP, accepted by SJU
• initial and final TS, accepted by SJU
• Execution of validation exercise EXE 09-W2-45 Act01


Solution 49

• An operation concept and specifications document (OSED) was produced and accepted by SJU .
• The Validation Plan (VALP) document produced and delivered to SJU for review. Approved in January 2021
• Transversal documents (i.e. Safety Plan, Human Performance Plan) produced and delivered to SJU for review. Approved in January 2021
• Development of prototype of a Network Performance Dashboard that was used as a demonstrator of the concept and proposed as tool for the Network Manager•
It is expected that solution SOL 44 will perform 2 main validation exercises each with 4 sub exercises and will reach full V3 level of maturity at the end of the project, allowing for deployment after SESAR2020.

Solution 45 was ended by the end of 2020 and produced a concept document (OSED) and a Technical Specification document and executed one exercise based on Artificial Intelligence technology applied for improving traffic predictability As a result of this early ending, some elements of the concept will be developed and validated directly with NM, allowing possible early deployment into operations.
