NEST

Network strategic modelling tool

Your simulation tool for network capacity planning and airspace design.

Log in Access conditions

The network strategic modelling (NEST) tool is simulation software for network capacity planning and airspace design.

    Functionality

    At EUROCONTROL, we use it in our capacity as the Network Manager (NM). We also provide it to air navigation service providers (ANSPs) to:

    • optimise the available resources and improve performance at network level; 
    • design and develop the airspace structure; 
    • plan capacity and perform post-operations analyses; 
    • organise traffic flows in the air traffic flow and capacity management (ATFCM) strategic phase; 
    • prepare scenarios to support fast- and real-time simulations for ad-hoc studies at local and network level.

    Access conditions

    To obtain the NEST software, you will need to access our Demand Data Repository (DDR). DDR is a simple and comprehensive web interface, accessible to registered users. DDR provides an accurate picture of pan-European air traffic demand, past and future, from several years ahead until the day before operations. It can be used to support network planning (strategic, seasonal and pre-tactical), for special events, or for major ATM development projects. If you are a DDR user:

    1. Access DDR
      The NEST software package is available on DDR, part of the OneSky Online platform. 
    2. Install
      Depending on your browser, you will either automatically download the file or you will be prompted to 'Run or Save' it. Save the file, go to your 'Download' (or other designated download folder) and run the installation (double-click on the file and follow the instructions).
    3. Launch
      Once the installation is complete, launch the main program from the 'Start menu' and begin using it.
