ENAV Deployment of traffic complexity tool and STAM phase 2

Implementing Partners

Leader: ENAV


The first part of the Implementation Project aims at the deployment of the Traffic Complexity Tool. Traffic complexity tool continuously monitors sector demand and evaluates 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).
The main objective of the Implementing Projects is to enhance the European ATM network performance, notably optimised capacity and flight efficiency, through the exchange, modification and management of aircraft trajectory information.
Flow Management shall move to a Cooperative Traffic Management (CTM) environment, optimising the delivery of traffic into sectors and airports whilst acknowledging the requirement for Air Traffic Flow and Capacity Management (ATFCM) measures. That will be achieved involving Network Manager in order to exchange information.
STAM (Short Term ATFCM Measures) Phase 2 procedures will be defined and implemented as required by EU 716/2014.
STAM consist of a system supported approach to smooth sector workloads by reducing traffic peaks through short‐term application of minor ground delays, appropriate flight level capping, timing and modalities of ATC re-sectorisation, exiguous re‐routings to a limited number of flights. These measures are capable of reducing the traffic complexity for ATC with minimum curtailing for the airspace users.
This project is complementary to IP 2016_114_AF4 ""ENAV Traffic Complexity Tool Implementation"" (Action 2016-EU-TM-0117-M) While IP 2016_114_AF4 aims at designing and developing the TCT, in IP 2017_045_AF4, the TCT will be implemented on all Italian ACCs and the design, the development and training of STAM2 procedures will be processed.

Specific objectives:

This IP specifically aims to:

  • Allow the implementation of the new operational concepts defined by Deployment Programme in the future ATM systems.

  • Facilitate the integration of advanced tools in the global ATM system.

  • Monitor and evaluate current and expected traffic loads and estimated controller’s workload in order to optimise the use of available capacity.

  • Involve the Network Manager in the initiative to exchange information.

  • design, develop, and implement the STAM phase 2 after the implementation of the Traffic Complexity Tool.

Expected Results:
At the end of the project the following results are expected:

  • TCT is implemented in all Italian ACCS: The tools will use predefined metrics to enhance long-term ATFCM, and/or enhanced planned trajectory prediction for mid-term ATFCM and/or real time trajectory data for short term ATFCM. Traffic complexity tools also enhance the real time ATCO workload estimation.

  • STAM2 procedure are designed, developed and Implemented.

  • Staff are trained.

Performance Benefits:

  • Enhancement of overall ATM system performances (expected at least a 5% increase)

  • Reduce delays by 3% and controller's workload by 5%."
