ENAV Traffic Complexity Tool Implementation

Implementing Partners

Leader: ENAV


Globally, the Implementation Project aims to develop the Traffic Complexity Tool. Traffic complexity tools continuously monitor sector demand and evaluate traffic complexity (by applying predefined complexity metrics) according to a predetermined qualitative scale. The predicted complexity coupled with traffic demand enables ATFCM (Air Traffic Flow and Capacity Management) to take timely action to adjust capacity, or request the traffic profile changes in coordination with ATC (Air Traffic Control), airspace users and NM (Network Manager).

In order to supplement the local traffic counts with the flight plan data and the Traffic Volume profile available from ETFMS (Enhanced Traffic Flow Management System), the local complexity tools will (if needed through B2B connection) receive, process and integrate EFD (Flight Data message) provided by NM.

Through the implementation, planned trajectory information, network information and recorded analytical data from past operations shall be used to predict traffic complexity and potential overload situations, allowing mitigation strategies to be applied at local and network levels. Extended Flight Plan (EFPL) shall be used to enhance the quality of the planned trajectory information thus enhancing flight planning and complexity assessments.

The design and system development are part of this project, the implementation will be executed in the context of a separate project. The Implementation Project uses the specifications developed under the CEF call 2014- #062AF4 project "ENAV initiative for the identification of Network Collaborative Management requirements" (2014-EU-TM-0136-M).
