Leader: Skeyes


The TCAST Implementation Project will implement a local traffic complexity assessment and simulations tool in the Brussels ACC. The Implementation Project covers several tasks including the installation, testing and fine tuning of the tool, the integration of EFD, NM, MET (meteorological) and other relevant data, the development of procedures and guidance information and the training of the operational and technical staff.
Following on from SESAR Solution ID #19, and the identified shortcomings in the current ATFCM process in place at Belgocontrol, the main objective of this Implementation Project is to :

  1. Support the efficient and dynamic handling of traffic by adjusting the sector capacity according to the traffic demand and its associated complexity. This will be achieved through:

  • Procurement and installation of a traffic complexity assessment and simulation tool.

  • Tuning of the system according to the particularities of the traffic and airspace under the responsibility of Belgocontrol (Brussels ACC/APP) as well as the parametrisation and fine tuning of the complexity algorithm and system outputs.

  • Redesigning the current way of working by introduction of traffic complexity metrics in the ATFCM process.

  1. Integrate internal and external data sources by:

  • Creating a Web Service B2B interface with the NM using the public internet and the SWIM YP.

  • Creating an interface to receive EFDs.

  • Creating internal interfaces with local systems: AMS, ARTAS, MET Systems....etc.

  1. Train and familiarize personnel by :

  • involving the end users during all phases of the project, with an emphasis on the tuning phase.

  • making participate the end users to a number of training sessions in order to get acquainted with the new system and its functionalities.

  • providing technical personnel with adequate training.
    The TCAST project already started in 2017 but only the activities (and related costs) starting from 12/04/2018 onwards are considered in the framework of the SGA.
    Specific objectives:
    The implementation project specifically aims to :

  1. acquire and implement a support system capable for real time monitoring, assessment and forecasting of air traffic complexity.

  2. integrate up-to-date and SWIM compliant information coming from several data sources (NM-B2B webservices, local systems).

  3. redesign the overall ATFCM concept and processes applied within Belgocontrol by considering the impact of traffic complexity in the decision making process with regard to Demand-Capacity Balancing (DCB).

Expected Results:

  1. A Traffic Complexity Tool is in operational use.

  2. ATFCM procedures are updated.

  3. Traffic flow is optimised.

Performance Benefits*:
The TCAST project will contribute to enhancements in the following key performance areas:

  1. Safety: positive impact due to better ATCO workload predictability (1%).

  2. Environment: positive impact due to the use of more optimal routes leading to reduction in emissions (1%).

  3. Capacity: positive impact due to the forecast of traffic complexity situations that would allow timely actions to be taken by the Traffic Manager (3%).

  4. Operational efficiency: positive impact (7%).

The above mentioned performance enhancements will bring benefits to Airspace Users, Belgocontrol and neighbouring Air Navigation Service Providers, the Network Manager and the Air Traffic Controllers.
